Apparently, it is possible for touchbar.m to compile on non-macos
machines. Also, the disable switch didn't actually work either. Fix this
by using the require() function and making sure that Cocoa (should be
apple-only) is found in addition to the compile check passing which is
what waf does. Fixes#10847.
This is a very simple but easy way of doing it. Ideally, it would be
nice if we could also add some sort of introspection about shader
parameters at runtime, ideally exposing the entire list of parameters as
a custom property dict. But that is a lot of effort for dubious gain.
It's worth noting that, as currently implemented, re-setting
`glsl-shader-opts` to a new value doesn't reset back previously mutated
values to their defaults.
In practice this never led to any issues due to implementation
details of bstr_sanitize_utf8_latin1, but there's no guarantee that
a bstr is correctly null-terminated.
This allows the core of mpv to know about issues in the AO.
Otherwise playback will just freeze as no more data callbacks are sent
by PipeWire.
Also it allows mpv to try to reconnect the AO or find another, working
AO.
We want to add more logic to the stream event handler.
This logic should not be triggered during normal stream shutdown, so we
remove the listener beforehand.
Workflow virtual machines have now been updated so that moby package
contains rule for the newly added syscalls, such as 'clone3'.
Effectively reverts 64fa440c69 .
This older image has been deprecated and will be removed in December.
The images have also already had planned outages during which the CI
flow has been affected. Thus it feels like a good idea to clean
this up at this point.

It turns out, even xy-VSFilter and XySubFilter do not
mangle colours if the video is native RGB regardless of
the sub's YCbCr header. libass' docs were also updated
to reflect this.
Deduplicate history like the fish shell. So for example
entering "cmd 1" then "cmd 2" then "cmd 3" then "cmd 1"
would result in a history of
[cmd 2][cmd 3][cmd 1]
instead of
[cmd 1][cmd 2][cmd 3][cmd 1]
Adds a function `history_add` to replace directly adding to history.
Adds an option `history_dedup` to activate the deduplication.
Defaults to on.
This was only needed because the mingw CI used to run on Ubuntu 20.04
which had a version of meson too old for mpv. This hasn't been the case
since we switched to 22.04 in f7164fcfac
and can now just use the package manager version.
Only matters when configuring ytdl_hook with `all_formats=yes`.
So far the tracks were ordered from worst to best quality.
Web players with quality selection always show the highest quality
option at the top. Since tracks are usually listed with the first
track at the top, that should also be the highest quality one.
yt-dlp/youtube-dl sorts it's formats from worst to best.
Iterate in reverse to get best track first.
This patch adds support for two extra WAVEFORMATEXTENSIBLE GUID tags
that can appear inside RIFF headers. It also adds support for extra
codec IDs that may appear as their own unique wSubFormats inside RIFF
headers, such as ATRAC9 inside matroska, as one example.
Fixes#10757.
I was confused in d3a28f12c9 why it
actually even worked, but after not being stupid, it's quite obviously
just a dangling pointer. The reason it only happens with
wp_presentation_feedback is because the object and listener actually
created in frame_callback not the presentation events itself (for vsync
timing reasons). So it is possible to free the object, but not
immediately recreate it again before quitting (unlike with the frame
callback). The actual comment is moved into feedback_presented (which is
first) but as of this commit it doesn't have the NULL setting logic
(that's the next one).
964692ad4c added some code to destroy
presentation_feedback we get in the presentation_discarded event. This
is the correct thing to do since the compositor could send us this
instead of feedback_presented. Without that change, mutter could
potentially leak memory on every frame.
Unfortunately, life is not so simple and wlroots and weston act
differently. These compositors only send one presentation_discarded
event if the mpv window is hidden. Not on every single missed frame like
mutter. Now in theory this shouldn't matter, but it also turns out that
mpv attempts to free the presentation feedback twice if you quit it
while it is hidden away (on weston and wlroots compositors only). The
inital wp_presentation_feedback_destroy in feedback_discarded fires, but
then the function goes off again in vo_wayland_uninit because
wl->feedback is apparently not NULL for some reason. Possibly, this is
some race condition but we can't just get rid of what's in
feedback_discarded since mutter needs this line. Instead, just hack it
by explicitly setting wl->feedback to NULL in feedback_discarded after we
destroy the presentation feedback. Some valgrind testing in mutter,
sway, and weston shows that this works correctly on all of those
compositors with various combinations of mpv being visible or not while
quitting. feedback_presented doesn't appear to exhibit this behavior so
we just leave that as-is.
666cb91cf1 added dmabuf_feedback, but it
was never actually free'd on uninit. Because this function requires
wayland protocols 1.24, we have to wrap it in an #if. Also throw in some
minor cosmetic changes in here.
This mapping isn't actually relevant until we have the Vulkan interop
merged, and it requires a newer version of libavutil than our minimum
requirement. So I'm going to remove it from master and put it in the
interop PR.
Fixes#10813
666cb91cf1 added support for v4 of the
dmabuf protocol. This was meant to be optional and the fallback support
for the old v2 (dates back to 2017[0] well before the 1.15
wayland-protocol version we depend on) was maintained. However, v4 added
several new functions and structs that of course aren't defined in old
protocol versions so naturally this breaks the build on those systems.
Since this is just a niche feature and not really critical to overall
wayland support in mpv, just give in and add another check in the build
system and #if out the newer stuff in wayland_common. v4 of linux-dmabuf
depends on wayland protocols 1-24[1], so go ahead and make that our new
check. Fixes#10807.

mpv has a CONFIGURATION define which is defined at configure time in
both build systems and printed out when you use verbose flags. In waf,
this is line is exactly what the user passes on cli at configure time.
In meson, there's currently no way to do that (someone did recently open
up a PR that would make this possible), so we just hardcode the prefix
and call it a day. This is a bit of a tangent, but the build also
copies waf and sets an optimize variable (true or false) that is also
printed out on verbose output. For waf, this makes some sense because
the build has a specific --optimize option (internally all it does is
pass -O2). In meson, optimizing is a built-in option and we just set
anything that's not -O0 as "optimize". Furthermore, there is a new
optimization option added in meson 0.64 called "plain" which passes no
flags at all* so this logic would need to be updated to account for
this.
In retrospect, this is all just stupid though. optimization is not a
boolean value and there's no real use for treating it like one just
because that's what waf does. Let's remove it from the features array.
Instead, we can expose this information in the CONFIGURATION variable
along with the prefix option so we know exactly what optimization was
used in the compiled executable. For good measure, let's also throw in
buildtype since it's related.

Meson's master branch helpfully prints out a warning here now saying
that "find_library('libdl') starting in "lib" only works by accident
and is not portable". We'll go ahead and trust them and instead change
this to dl which works with no issues.
The old "meson build" build command was actually deprecated a few months
ago*. It turns out that you're supposed to use "meson setup build"
instead which has been around for years. Go ahead and be a good citizen
and update this in the CI. Also replace any mention of "meson build"
with "meson setup build" in the documentation as well and change the one
random hardcoded string we have in meson.build to "meson configure
build" (might as well).

Console already respected the bottom margin to not overlap with the
bottom bar from the OSC, but it would still overlap with the window
decorations from the OSC.
Now everything is clipped above the top margin and no superfluous lines
are drawn.
vo_dmabuf_wayland has its own ra and context so it can handle all the
different hwdec correctly. Unfortunately, this API was pretty clearly
designed with vo_gpu/vo_gpu_next in mind and has a lot of concepts that
don't make sense for vo_dmabuf_wayland. We still want to bolt on a
ra_ctx, but instead let's rework the ra_ctx logic a little bit. First,
this introduces a hidden bool within the ra_ctx_fns that is used to hide
the wldmabuf context from users as an option (unlike the other usual
contexts). We also want to make sure that hidden contexts wouldn't be
autoprobed in the usual ra_ctx_create, so we be sure to skip those in
that function. Additionally, let's create a new ra_ctx_create_by_name
function which does exactly what says. It specifically selects a context
based on a passed string. This function has no probing or option logic
is simplified just for what vo_dmabuf_wayland needs. The api/context
validations functions are modified just a little bit to make sure hidden
contexts are skipped and the documentation is updated to remove this
entries. Fixes#10793.
vo_gpu and vo_gpu_next typically load hwdec interops on demand and
vo_dmabuf_wayland naively copied this logic. This is actually wrong
however since draw_frame in the VO always inherently relies on hwdec
being fully loaded. This can lead to a race condition during startup
which happens with --force-window=immediate. Avoid this by simply always
loading all the interops. In the case of vo_dmabuf_wayland, this is not
really a big deal since there's only vaapi and drmprime to load. Also
fixes#10791 (the other half).
We really need two roundtrips in the init function. The first one is for
running the registry and then second one is for ensuring the xdg_surface
and other potential wayland objects are configured at least once before
mpv does anything. We've been getting away with only doing the first for
a while via luck, but really we should do at least one more wait on the
compositor. Fixes#10791 (half of it).
Despite being run in a VM, the workflow actually copies the files back
to the host. We can then explictly print the error logs on failure in
their own separate section for visibility instead of it being hidden
within all the vm output.
Building on DRM platform without VAAPI broke because of misuse of
HAVE_VAAPI with #ifdef in place of #if. Also, the hwcontext_drm.h
header is not required for VAAPI builds, only DRM builds.
Originally, I considered warning once to be useful for figuring
out whether the change in logic regarding resetting requested
mode actually fixed the reported issue or not, but alas not everyone
was happy with that decision. Thus the log level will always be
debug. This enables us to lose one level of indent as well as a
variable, which is always positive.
Additionally, make the message more explicit regarding what could
possibly be implied by the mismatch, as it seems like this was
not always clear.
Otherwise mpv and the compositor can end up in an eternal loop where
mpv requests one mode, and compositor tells that the mode is not
that (and will most likely not change).
Additionally, log these mismatches - first time as a warning, and
later as debug logging.
It is verbose, but makes it more explicit that requested_decoration
takes in three values:
* 0: no specific mode requested by mpv
* ZXDG_TOPLEVEL_DECORATION_V1_MODE_CLIENT_SIDE: (!border)
* ZXDG_TOPLEVEL_DECORATION_V1_MODE_SERVER_SIDE: (border)

The zwp_linux_dmabuf_v1 protocol version 4 provides a file descriptor
containing both formats and modifiers, which makes it possible for the
compositor to import the buffers onto planes using explicit modifiers.
This is an extremely important efficiency improvement, as the 3D
hardware can be left powered off altogether, the vaapi buffer being sent
directly from the video hardware to the display controller.
It could be possible to support zwp_linux_dmabuf_v1 version 3 as well,
but there is no reason beyond compatibility with old stacks. I would
recommend to ditch version 2 as well, as modifier-less formats aren’t
very useful nowadays.
Wayland VO that can display images from either vaapi or drm hwdec
The PR adds the following changes:
1. a context_wldmabuf context with no gl dependencies
2. no-op ra_wldmabuf and dmabuf_interop_wldmabuf objects
no-op because there is no need to map/unmap the drmprime buffer,
and there is no need to manage any textures.
Tested on both x86_64 and rk3399 AArch64
dmabuf-wayland vo supports both DRMPRIME and VAAPI formats.
If upload filter is needed, we want to try VAAPI hwdec first
since most users will be using VAAPI, and there is a several second
delay when DRMPRIME hwdec is tried and fails.
Pushing E (aka Shift+e) cycles through Editions for containers
that support editions, such as Matroska, although this feature was not
documented before this commit.
The AO is feature-complete now.
As PipeWire also provides compatibility with PulseAudio, ALSA and Jack
we should put it before those for the autodetection to work.
The pure presence of PipeWire does not mean that it is actually driving
the audio session. For example it could only be meant for video.
Currently there is no proper API to detect this (see [0]), so we check
for the presence of audio sinks.
As soon as a proper API exists, we should use that.

It turns out that wayland-scanner and wayland-protocols are both exposed
as configure options in waf meaning you can --enable/--disable them at
configure time. This is pretty nonsensical. If you want to control
wayland in the build, you should just use --enable-/--disable-wayland.
wayland-scanner and wayland-protocols should just be typical checks like
in the meson build.
vaapi allows for implicit conversion on upload, which has some
relevance as the set of supported source formats is larger than the
set of displayable formats. In theory, this allows for offloading the
conversion to the GPU - if you have any confidence in the hardware
and/or driver's ability to do the conversion.
Today, we actually track the 'input' and 'output' upload formats
separately all the way up until the point we do a check as to whether
the original source format is an accepted 'output' format and then
reject it if it is not.
This means that we're essentially ignoring all the work we did to track
those 'input' formats in the first place. But it also means that it's a
simple change to compare against the 'input' format instead. The logic
is already in place to do best format selection on both sides.
I imagine that if I read through the history here, wm4 tried to
implement all of this properly and then gave up in disgust after seeing
vaapi mangle various conversions.
This is particularly interesting for vo-dmabuf-wayland where it is only
possible to display the subset of valid vaapi formats that are
supported by the compositor, yet all playback has to go through vaapi.
Users will then be able to take advantage of all possible vaapi formats
to avoid having to do software format conversion.
This has been a long standing problem that I think was the root cause
for wm4's vaapi shitlist. As DRM explicit supports all possible rgba
orderings, but OpenGL only guarantees support for 'rgba8', something
has to happen to support import of dmabufs with non-native ordering.
Although undocumented, it appears that somewhere in the import on the
GL side, the ordering is swizzled to rgba - which makes sense as that's
the only way to be able to support importing all the different formats.
But we didn't know this, and we do our own swizzling based on the
original imgfmt - which matches the drm format. So we get double
swizzling and messed up colours.
As there is no way for us to express that the GL swizzle happened to
the rest of mpv, the easiest thing to do is fudge the format to the
natural ordering so the GL doesn't change anything, then our swizzling
will do the right thing in the end.
Note that this change doesn't handle 0rgb and 0bgr because they seem to
be affected by some additional feature/bug that is mangling the
ordering somewhere that equally affects Vulkan interop. That could be a
vaapi driver bug or something going on in ffmpeg.
A few years ago, wm4 got sufficiently annoyed with how vaapi image
format support was being discovered that he flipped the table and
introduced the shit list (which just included vaapi) to hard-code the
set of supported formats.
While that might have been necessary at the time, I haven't been able
to find a situation where the true list of supported formats was unsafe
to use. We filter down the list based on what the vo reports - and the
vo is already doing a thorough testing of formats, and if a format
makes it through that gauntlet, it does actually work.
Interestingly, as far as I can tell, the hwdec_vaapi probing code was
already good enough at the time (also written by wm4), so perhaps the
key difference here is that the driver side of things has improved.
I dug into this because of the support for the 422/444 high bit depth
vaapi formats I added to ffmpeg. These are obviously not in the hard
coded list today, but they work fine.
Finally, although it's positioned as a vaapi thing, it's really just
Intel specific, as the AMD vaapi driver has never exposed support for
anything except the formats used by the decoder/encoder profiles.
The logic around trying to establish what formats are supported by
vaapi is confusing, and it turns out that we've been doing it wrong.
Up until now, we've been going through the list of decoding profile
endpoints and checking the formats declared in those profiles to build
our list.
However, the set of formats that the vaapi driver can actually support
is potentially a superset of those supported by any given profile
endpoint. This master list is exposed by libavutil via the
av_hwframe_transfer_get_formats() function, and so we should use that
list as our starting point.
Perhaps surprisingly, this change actually removes no code, because we
still want the logic that enumerates endpoints and finds supported
formats for endpoints. We need this because we must have at least one
known sw format to initialise the hwframe_ctx with.
Additionally, while in the general case,
av_hwframe_transfer_get_formats can return different formats depending
on what format you initialise the hwframe_ctx with, I happen to have
read the libavutil code, and it doesn't care, so we just need to call
it once, we know we'll get back all known formats.
In practice, with an Intel vaapi driver, this will result in us
supporting a handful of extra formats for hwuploads - particularly
yuv420p (so no need to convert to nv12 first) and various orderings
of rgb(a).
Commit 740b701 introduced handling for subtitles with unknown duration,
but it came with a minor flaw where a track event that shares identical
start time with following track event will has its Duration value set
to 0, we don't want this to happen since it will prevent simultaneous
rendering of multiple track events.
This commit aims to address this issue.
When the width is exactly a multiple of SLICE_W (currently 256),
heap buffer overflow is reported by Address Sanitizer. So adjust
the maximum index for the line array accordingly.
We've had some annoying names for interops, which we can't simply
rename because that would break config files and command lines. So we
need to put a little more effort in and add a concept of legacy names
that allow us to continue loading them, but with a warning.
The two I'm renaming here are:
* vaapi-egl -> vaapi (vaapi works with Vulkan too)
* drmprime-drm -> drmprime-overlay (actually describes what it does)
* cuda-nvdec -> cuda (cuda interop is not nvdec specific)
mpv set _NET_WM_DESKTOP to 0xFFFFFFFF, which behaves differently with each window manager.
Instead, set the window property to STICKY, and let the window managers deal with it.
The new status quo is simple: all messages coming from libplacebo are
marked "vo/gpu{-next}/libplacebo", regardless of the backend API (vulkan
vs opengl/d3d11).
Messages coming from mpv's internal vulkan code will continue to come
from "vo/gpu{-next}/vulkan", and messages coming from the vo module
itself will be marked "vo/gpu{-next}".
This is significantly better than the old status quo of vulkan messages
coming from "vo/gpu{-next}/vulkan/libplacebo" whereas opengl/d3d11
messages simply came from "vo/gpu{-next}", even when those messages
originated from libplacebo.
(It's worth noting that the the destructor for the log is redundant
because it's attached to the ctx which is freed on uninit anyway)
Managed to go completely unnoticed for months (who was the bad person
that introduced these*). Fairly self-explanatory. After getting
ProviderInfo from randr, we need to free it. The other one is pretty bad
because it leaked every frame (ouch). It turns out that you're supposed
to free any event data after you cast a generic event to an
XGenericEventCookie. Free that as well.
*: It was me.
The wayland presentation time code currently always assumes that only
CLOCK_MONOTONIC can be used. There is a naive attempt to ignore clocks
other than CLOCK_MONOTONIC, but the logic is actually totally wrong and
the timestamps would be used anyway. Fix this by checking a use_present
bool (similar to use_present in xorg) which is set to true if we receive
a valid clock in the clockid event. Additionally, allow
CLOCK_MONOTONIC_RAW as a valid clockid. In practice, it should be the
same as CLOCK_MONOTONIC for us (ntp/adjustime difference wouldn't
matter). Since this is a linux-specific clock, add a define for it if it
is not found.
This has had no effect since libplacebo v4.192.0, and was deprecated
upstream a year ago. No deprecation period in mpv is justified by this
being a debug / work-around option.
Removed the outdated information about environmental brightness
with respect to --gamma-factor, and mention that the option is
deprecated and subject to future removal. Also deprecated the
--gamma-auto option as it relies on the same outdated way of doing
things.
This brings vo_gpu_next's behavior more in line with vo_gpu. Currently,
the status quo was that `vo_gpu_next` generated subtitles with the full
resolution of the dst crop, even though practical limitations of
libplacebo meant that such subtitles inevitably got cut off at the video
boundaries. This was actually a worse status quo than `vo_gpu`, which
simply constrained subtitles to the video dimensions to prevent these
issues.
With this change, the behavior is the same as `vo_gpu`, which has the
exact same problem w.r.t interpolation. Users are back to choosing
between --blend-subtitles=yes and not having subtitles in margins,
and using --blend-subtitles=no and not having subtitle interpolation.
There are different pros and cons to each approach, and I still
ultimately plan on allowing libplacebo to interpolate subtitles even in
the black bars, to solve this issue once and for all. But for now, let's
not let perfect be the enemy of good.
No attempt is made to implement `--blend-subs=video`, which I consider
deprecated.
Fixes: https://github.com/mpv-player/mpv/issues/10272
Specifying the id of the target node during stream connect is
deprecated. Instead the property target.object should be used to link
by target serial or name. Using the name allows us to drop a bunch of
custom code.
I actually don't quite understand why this is needed, since in theory we
should already be doing the rotation as part of applying the crop. But I
guess that code doesn't quite work. This is the only way it works, so
it's probably correct. (And note that `vo_gpu` does the same internally)
This fixes an issue where blend stages with multiple passes got
overwritten by later passes, with only the final pass (typically the
overlayp pass) actually being shown.
Alphabetizing the extensions cleans up the code and makes it less
ambiguous where newer extensions should be added. The video line
also was wrapped to 72 characters for cleanliness.
When af_scaletempo2.c:process() detects a format change, it goes back
through mp_scaletempo2_init() to reinitialize everything. However,
mp_scaletempo2.input_buffer is not necessarily reallocated due to a
check in af_scaletempo2_internals.c:resize_input_buffer(). This is a
problem if the number of audio channels increases, since without
reallocating, the buffer for the new channel(s) will at best point to
NULL, and at worst uninitialized memory.
Since resize_input_buffer() is only called from two places, pull size
check out into mp_scaletempo2_fill_input_buffer(). This allows each
caller to decide whether they want to resize or not. We could be
smarter about when to reallocate, but that would add a lot of machinery
for a case I don't expect to be hit often in practice.
Certain combinations of hardware formats require the use of hwmap to
transfer frames between the formats, rather than hwupload, which will
fail if attempted.
To keep the usage of vf_format for HW -> HW transfers as intuitive as
possible, we should detect these cases and do the map operation instead
of uploading.
For now, the relevant cases are moving between VAAPI and Vulkan, and
VAAPI and DRM Prime, in both directions. I have introduced the IMGFMT
entry for Vulkan here so that I can put in the complete mapping table.
It's actually not useless, as you can map to Vulkan, use a Vulkan
filter and then map back to VAAPI for display output.
Historically, HW -> HW uploads did not exist, so the current code
assumes they will never happen. But as part of introducing Vulkan
support into ffmpeg, we added HW -> HW support to enable transfers
between Vulkan and CUDA.
Today, that means you can use the lavfi hwupload filter with the
correct configuration (and previous changes in this series) but it
would be more convenient to enable HW -> HW in the format filter so
that the transfers can be done more intuitively:
```
--vf=format=fmt=cuda
```
and
```
--vf=format=fmt=vulkan
```
Most of the work here is skipping logic that is specific to SW -> HW
uploads doing format conversion. There is no ability to do inline
conversion when moving between HW formats, so the format must be
mutually understood to begin with.
Additional work needs to be done to enable transfers between VAAPI
and Vulkan which uses mapping, rather than uploads. I'll tackle that
in the next change.
Today, lavfi filters are provided a hw_device from the first
hwdec_interop that was loaded, regardless of whether it's the right one
or not. In most situations where a hardware based filter is used, we
need more control over the device.
In this change, a `hwdec_interop` option is added to the lavfi wrapper
filter configuration and this is used to pick the correct hw_device to
inject into the filter or graph (in the case of a graph, all filters
get the same device).
Note that this requires the use of the explicit lavfi syntax to allow
for the extra configuration.
eg:
```
mpv --vf=hwupload
```
becomes
```
mpv --vf=lavfi=[hwupload]:hwdec_interop=cuda-nvdec
```
or
```
mpv --vf=lavfi-bridge=[hwupload]:hwdec_interop=cuda-nvdec
```
If we want to be able to handle conversion between hw formats in filter
chains, then we need to be able to load hwdec_interops from filters, as
the VO is only ever going to initialise one interop, based on its
configuration. That means that in almost all situations, only one of
the required interops will be loaded at the time the filter is
initialised.
The existing code has some assumptions that new hwdec_interops will not
be loaded after the vo has picked one to use. This change fixes two
instances:
* Refusing to load a new hwdec_interop if there is at least one
loaded already.
* Not recalculating the set of formats known to the autoconvert
filter when a new output format shows up. This leads to autoconvert
not knowing that a new format is supported when the hwdec interop is
lazily loaded.
It turns out that it's generally more useful to look up hwdecs by image
format, rather than device type. In the situations where we need to
find one, we generally know the image format we're dealing with. Doing
this avoids us having to create mappings from image format to device
type.
The most significant part of this change is filling in the image format
for the various hw interops. There is a hw_imgfmt field today today, but
only a couple of the interops fill it in, and that seems to be because
we've never actually used this piece of metadata before. Well, now we
have a good use for it.
ASS must only automatically break at ASCII spaces (\x20), but other
subtitle formats might expect more breaking oppurtinities.
Especially non-ASS subs in scripts, which typically do not use (ASCII)
spaces to seperate words, like e.g. CJK, might overflow the screen
if the conversion didn't insert additional linebreaks (ffmpeg does not).
Thus try to enable Unicode linebreaking for converted subs and the OSD
if libass is new enough. The feature may still be unavailable at runtime
if libass wasn't build with Unicode linebreaking support.
Previously, running a debug build of mpv would crash with this output

but the Swift runtime began asserting on it in debug builds a couple macOS
versions ago.
Previously we would only call list_devs() on available AOs if an AO
*did not* have a hotplug_init() callback or for the first one that *did*
have it.
This is problematic when multiple fully functional hotplug-capable AOs
are available.
The second one would not be able to contribute discovered devices.
This problem prevents ao_pipewire from introducing full hotplug support
with hotplug_init().
When a platform has multiple valid AOs that can provide hotplug events
we should try to use the one that also provides playback.
Concretely this will help when introducing hotplug support for
ao_pipewire.
Currently ao_pulse is probed by ao_hotplug_get_device_list() before
ao_pipewire and on the common setups where both AOs could work pulse
will be selected for hotplug handling.
This means that hotplug_init() of ao_pipewire will never be called and
list_devs() has to do its own initialization.
But if ao_pulse is non-functional or not compiled-in suddenly
ao_pipewire *must* implement hotplug_init() for hotplugging events to
work for all.
Also if the hotplug ao_pulse connects to a PulseAudio instance that is
not emulated by the same PipeWire instance as the playback ao_pipewire
the hotplug events are useless.
30 characters are not a lot.
Also when the name is calculated from the allocation site the line
number will be the at the end of the name, so truncating it is
especially inconvenient.
I'm adding support in ffmpeg for the XV36 format which will be used
by VAAPI for 12bit 4:4:4 content. It's an undefined-alpha channel
variant of Y412 which is itself a 12bit+4bits padding variant of Y416.
We currently have a repacker for full four channel cccc16, and for
three channel ccc16, but nothing for ccc16x16 with the undefined alpha
channel.
It's simple enough to add one using the existing macros.
uau did some investigation and noticed that we do not send a wakeup
event when we encounter end-of-stream in ao_read_data(), in contrast to
the equivalent logic for push AOs in ao_play_data().
Inserting that wakeup fixes the original problem of lack of
reinitialization on a format change without the problems we saw with
the previous attempted fix.
Fixes#10566
We have previously had a problem where pull AOs (such as pipewire)
would not reinitialize on a format change when going between two
audio-only files. In such a situation, playback would stop after the
first file.
We initially attempted to fix this by explicitly draining on EOF, which
solves that problem but introduces a blocking step where we don't
actually want one, breaking gapless audio, and causing dropped frames
at the end of playback for files with video in them too.
So, let's undo these changes and do something better in the next
commit.
The error description in #10545 could indicate that we are overflowing
we are corrupting the buffer metadata ourselves through out-of-bound
writes.
This check is also present in pw-cat so it seems to be expected for
b->requested to exceed the actual available buffer space.
Potential fix for #10545
52aed495cb ("audio: drain ao on EOF") introduced logic to drain an AO
when EOF of the input has been reached.
When no AO however is present this leads to a NULL-dereference.
Fixes#10556
Facing down the multitude of ways to somehow wrangle the get_fn pointer
out of the GL environment and into libplacebo, I decided the easiest is
to just store it inside the GL struct itself.
The lifetime of this get_fn function is a bit murky, since it's not
clear on whether or not it survives the VO init call (especially in the
case of the GL render API, which explicitly states that parameters do
not need to survive the call they're passed to), so just add a
disclaimer.
(It's fine for us to use like this because `gpu_ctx_create` is still
part of VO init)

Every format that was not detected as a video format was added to the
audio tracks. This resulted in e.g. YouTube storyboards from ending up
in the list of audio tracks.
Now formats that are already known to be neither video formats nor audio
formats, will also not end up in any track list.
Formats where it is unknown if they are video or audio get added to
tracks if `force_all_formats` is used, otherwise only
formats that are known to contain video or audio become video or audio
tracks respectively.

Add xoshiro as a PRNG implementation instead of relying
on srand() and rand() from the C standard library. This,
in particular, lets us avoid platform-defined behavior with
respect to threading.
Since the previous commit introduced the notion of a features dictionary
that conveniently tells us whether or not to use a feature in a simple
yes/no, we can make use of this everywhere in the build. Instead of
doing something like 'if foo.()', change it to 'if feature['foo']
instead. This enforces a consistent standard instead of having a lot of
different possible combinations of booleans that may or may not do
something.
mpv has a ton of defines that are generated during building. Previously,
the meson build just had this as a big giant wall of text that manually
set each one but we can do this smarter. Instead, change the "features"
object to a dictionary and have it hold the name of the feature and its
value (true/false on whether it is enabled). Then at the end, just loop
through it and reformat the name of the feature so it becomes
HAVE_FEATURE. A side effect of this is that a lot of extra defines are
generated that aren't actually used in the code, but the waf build
worked like this for years anyway. A nice result of this is that the use
of foo['use'] internally can be completely eliminated and replaced with
feature['foo'] instead when needed.
The build was a bit overzealous with using dictionaries. These are fine
for when the feature checking is more complicated, but there's no point
in having them for the simplier things. This also eliminates the usage
of the 'name' key completely.
One would expect that e.g.
`--script-opts=ytdl_hook-all_formats=no --ytdl-format=bestaudio` and
`--script-opts=ytdl_hook-all_formats=yes --ytdl-format=bestaudio`
to play the exact same tracks without manual intervention.
This already worked when two formats were requested.
For a single format with `all_formats=yes` it would also play a track
that was not requested when available. This was inconsistant with the
behavior of `all_formats=no` (default), which would not play a second
track when only a single one was requested.
This combined with #10395 now plays the exact same tracks with
`all_formats=yes` as without, even when only one format is requested.
In wayland-protocols 1.25, xdg-shell got a version bump which added the
configure_bounds event. The compositor can send this to clients to
indicate that they should not resize past a certain size. For mpv, we'll
choose to only listen to this on reconfig events (i.e. when the window
first appears and if the video resolution changes later in the
playlist). However, this behavior is still exposed as a user option
(default on) because it will neccesarily conflict with a user setting a
specific geometry size and/or window scale. Presumably, if someone is
setting a really large size that goes beyond the bounds of their
monitor, they actually want it like that. The wayland-protocols version
is newer-ish, but we can get around having to poke the build system by
just using a define that exists in the generated xdg-shell header.
Unexpectedly, x11->screenrc actually doesn't update with randr events.
In a multimonitor configuration it could easily be wrong depending on
the user's layout. While it's tempting to modify the logic so screenrc
changes with randr events, this rectangle is currently used everywhere
and as far as we know, this pretty much works fine. Instead, just loop
over the randr displays that we have and select it if it overlaps with
the winrc. This follows the same logic as the fps selection in the case
of the mpv window overlapping multiple monitors (the last one is
selected).
Tracks are marked as default tracks based on what yt-dlp/youtube-dl
returns in the field `requested_formats`. The problem is that this field
only exists when there is more then one requested format.
So `ytdl-format=bestvideo+bestaudio` would have that field,
but `ytdl-format=bestaudio` would not,
leading to no tracks being marked as default tracks.
The requested formats can also be found under `requested_downloads`,
which exists regardless of the number of requested formats.
However when there is more then one requested format,
`requested_downloads` doesn't contain those formats directly and instead
has a field `requested_formats` that is identical to the other
`requested_formats`. Therefore use `requested_downloads` as a fallback
for when `requested_formats` doesn't exist.
ae768a1e14 forgot to bump the required
libdrm version however Debian 11 just barely misses the requirement,
which is a good reason not to require it unconditionally anyway.
The older overlay based drmprime hwdec should be preferred to the new
texture mapping one. This is for a few reasons:
1. In any situation where both hwdecs work, it's probably right to use
the more mature one by default, for now.
2. It seems like the overlay path primarily works on older SoCs
where the texture path is less performant, and in at least one
tested case is visually buggy, so you definitely want it to be
tried first.
3. In situations where the old hwdec doesn't work, it will fall through
to the new one.
sfan5 found a few things after I pushed the change, so this fixes them.
* Use-after-free on drm_device_Path
* Not comparing render_fd against -1
* Not handling dup() errors
This gives pull-based AOs the chance to play all queued audio.
Also it will make sure that the audio has finished playing so we can
reinitialize the AO if format changes are necessary.

In the confusing landscape of hardware video decoding APIs, we have had
a long standing support gap for the v4l2 based APIs implemented for the
various SoCs from Rockship, Amlogic, Allwinner, etc. While VAAPI is the
defacto default for desktop GPUs, the developers who work on these SoCs
(who are not the vendors!) have preferred to implement kernel APIs
rather than maintain a userspace driver as VAAPI would require.
While there are two v4l2 APIs (m2m and requests), and multiple forks of
ffmpeg where support for those APIs languishes without reaching
upstream, we can at least say that these APIs export frames as DRMPrime
dmabufs, and that they use the ffmpeg drm hwcontext.
With those two constants, it is possible for us to write a
hwdec-interop without worrying about the mess underneath - for the most
part.
Accordingly, this change implements a hwdec-interop for any decoder
that produces frames as DRMPrime dmabufs. The bulk of the heavy
lifting is done by the dmabuf interop code we already had from
supporting vaapi, and which I refactored for reusability in a previous
set of changes.
When we combine that with the fact that we can't probe for supported
formats, the new code in this change is pretty simple.
This change also includes the hwcontext_fns that are required for us to
be able to configure the hwcontext used by `hwdec=drm-copy`. This is
technically unrelated, but it seemed a good time to fill this gap.
From a testing perspective, I have directly tested on a RockPRO64,
while others have tested with different flavours of Rockchip and on
Amlogic, providing m2m coverage.
I have some other SoCs that I need to spin up to test with, but I don't
expect big surprises, and when we inevitably need to account for new
special cases down the line, we can do so - we won't be able to support
every possible configuration blindly.
Whether or not the GNOME project has a tendency to make life
difficult for anyone outside their ecosystem, the user manual is
no place for childish rants such as this.
Keep it to what is relevant for users.
I already added the equivalent logic for dmabuf_interop_pl previously
but I skipped the GL support because importing dmabufs into GL requires
explicitly providing the DRM format, and if you are taking a
multi-plane format and trying to treat each plane as a separate layer,
you need to come up with a DRM format for each synthetic layer.
But my initial testing has shown that the RockPRO64 board I've got to
work on drmprime hwdec will only produce NV12 in a single layer multi
plane format, and it doesn't have Vulkan support, so I have had to
tackle the GL multi-plane problem.
To that end, this change introduces the infrastructure to provide new
formats for synthetic layers. We only have lookup code for NV12 and
P010 as these were the only ones I could test.
Annoyingly, libva and libdrm use different structs to describe dmabufs
and if we are going to support drmprime, we must pick one format and do
some shuffling in the other case.
I've decided to use AVDRMFrameDescriptor as our internal format as this
removes the libva dependency from dmabuf_interop. That means that the
future drmprime hwdec will be able to populate it directly and the
existing hwdec_vaapi needs to copy the struct members around, but
that's cheap and not a concern.
With the files renamed, we can now disentangle the shared private
struct between the interops and hwdec_vaapi. We need this separation
to allow the future drmprime hwdec to use the interops.
This is the first in a series of changes that will introduce a drmprime
hwdec. As our vaapi hwdec is based around exporting surfaces as
drmprime dmabufs, we've actually got a lot of useful code already in
place in the GL/PL interops. I'm going to reorganise and adjust this
code to make the interops usable with the new hwdec as well.
The first step is to rename the files and functions. There are no
functional or other changes here. They will come next.
Avoids another pitfall on systems where the first card has a primary
node but is not capable of KMS. With this change --drm-context=drm
should work correctly out-of-the-box in all cases.
On S905X (meson) boards drmModeAtomicCommit called from
disable_video_plane in hwdec_drmprime_drm.c might still be running when
another call is made from queue_flip in context_drm_egl.c.
This causes EBUSY error in queue_flip, and causes mpv to hang.
The example given in #3024 would not play the correct video when
combined with `--ytdl-raw-options=yes-playlist=`.
Allowing `youtube:tab` as extractor and correcting the id check fixes
that.
This is somewhat academic for now, as we explicitly ask for separate
layers and the scenarios where multi-plane images are required also use
complex formats that cannot be decomposed after the fact, but
nevertheless it is possible for us to consume simple multi-plane
images where there is one layer with n planes instead of n layers with
one plane each.
In these cases, we just treat the planes the same as we would if they
were each in a separate layer and everything works out.
It ought to be possible to make this work for OpenGL but I couldn't
wrap my head around how to provide the right DRM fourcc when
pretending a plane is a layer by itself. So I've left that
unimplemented.
A VRAM memory leak was present in d3d11 when `idle=yes` and playback
stops for an item. This patch re-enables some of the code which is
only used during diagnostic which fixes the issue.
Generally, the hard-coded sizes used for the OSC elements are
comfortable regardless of the font used, but the timecode fields have
relatively many characters, and so are affected to a greater degree by
fonts with a wider or narrower average character width than expected.
This allow users to adjust the space reserved for the timecode fields to
compensate.
Using cmsFLAGS_HIGHRESPRECALC results in Little-CMS generating an
internal 49x49x49 3DLUT, from which it then samples our own 3DLUT. This
is completely pointless and not only destroys the accuracy of the 3DLUT,
but also results in no additional gain from increasing the 3DLUT
precision further.
The correct flag for us to be using is cmsFLAGS_NOOPTIMIZE, which
suppresses this internal 3DLUT generation and gives us the full
precision. We can also specify cmsFLAGS_NOCACHE, which is negligible but
in theory prevents Little-CMS from unnecessary pixel equality tests.
pw_core_disconnect frees the core, so accessing it afterward to
destroy the context is not allowed.
Instead, just destroy the context, the first thing it does is disconnect
all cores for us.
mpv only remembers volume for two channels.
Always apply the same volume to all channels in case of
non-stereo layout similarly to ao_pulse.
Don't try to do anything smart when averaging volumes,
normally they are equal anyway.
This was introduced in 7fb972fd39 and
later revised in f5a094db04. Transparency
in EGL/X11 has been broken upstream for years in Mesa unfortunately.
However, the first commit claimed to have found a way to preserve
transparency by doing a trick with picking EGLConfigs (the second commit
revises this but keeps the logic in place). However, it doesn't appear
that the first commit actually fixes anything (transparency doesn't work
on my machine) and no one else seems to have reported it working. On the
other hand, if Mesa does ever actually fix this, transparency would
immediately be broken since mpv would always set the EGL_ALPHA_SIZE to
0. Go ahead and remove this since it doesn't seem to have any actual
utility and is technically a bit of a timebomb (not that deleting two
lines is a lot of work but still) if upstream ever does fix this.
The meson build does a lot of checks and if you aren't familiar with the
internals of the meson.build, it may not be clear what is actually
enabled and what isn't. It turns out that meson has a handy function,
summary, exactly for this. This just prints a pretty summary of some
notable features in the build. It's not meant to be a comprehensive
list, but rather just what users are likely to care the most about (i.e.
x11, vulkan, etc.)
This was introduced in 04257417 without a clear explanation of the bug
it was solving, so I have no idea if it's still needed (or why it ever
was). And it definitely creates unexpected behavior, e.g. forced
clipping when converting between float and floatp.
I therefore think we should simply remove this logic and see if it
regresses anything else, then fix those other bugs *properly* (if
they're still around).
Fixes#9979
Commit 7f4841ff sorted the bindings so that if the same key was bound
more than once, then the newest binding takes priority (sorted last).
However, it got the comparison function wrong, which means the result
of the sort depended on the algorithm and not on the actual data, so
the priority for keys with more than one binding was still arbitraty.
Fix the sort function, and finally ensure that later binding acutally
override earlier bindings of the same key.
This commit kind of mixes several related things together. The main
thing is to avoid calling any XPresent functions or internal functions
related to presentation when the feature is not auto-whitelisted or
enabled by the user. Internally rework this so it all works off of a
use_present bool (have_present is eliminated because having a non-zero
present_code covers exactly the same thing) and make sure it updates on
runtime. Finally, put some actual logging in here whenever XPresent is
enabled/disabled. Fixes#10326.
Previously if the raw command_native_async returned an error then the
callback function was run directly. This meant that script writers
potentially had to account for both synchronous and asynchronous logic
in the callback, which can happen even with seemingly 'safe' commands
if the mpv event queue is full.
This was at odds with the Javascript implementation of
the function, which always runs the callback asynchronously.
Now the mp.add_timeout function is used to run the callback
asynchronously on error, replicating the Javascript implementation.
This provides consistency for developers in how the callback is handled
in Lua, and increases consistency between the Lua and Javascript APIs.
With the recent addition of the libxpresent, it should improve frame
timings for most users. However, there were known cases of bad behavior
(Nvidia) which lead to a construction of a whitelist instead of just
enabling this all the time. Since there's no way to predict whatever
combination of hardware/drivers/etc. may work correctly, just give users
an option to switch the usage of xorg's presentation statistics on/off.
The default value, auto, works like before (basically, Mesa drivers and
no Nvidia are allowed), but now one can force it on/off if needed.
The old logic always reset the x11->has_mesa/has_nvidia values on every
loop through the provider. This meant that it would always just match
whatever the last provider happened to be. So in the case of a dual GPU
system, if nvidia was the very first provider and the integrated
intel/amd card was the second (in practice, this is probably mostly the
other way around), then mpv would set has_mesa to true and has_nvidia to
false and thus try to use presentation. This is not the intended
behavior. Just rework this by also checking x11->has_mesa/has_nvidia in
the loop so a true value from the previous iteration is preserved.
This code was taken from the older vo_vaapi driver, which does
use the vaapi format list, but the new driver has no use for
these formats, as it is only interested in va surfaces that
can be mapped to wl buffers. The format doesn't enter into
it at all.
Immediately after this, d3d11 is defined again and the rest of the
meson.build uses that. Probably, this dictionary was from the original
meson PR and removing it was forgotten at some point while stuff was
being rewritten.
This builds off of present_sync which was introduced in a previous
commit to support xorg's present extension in all of the X11 backends
(sans vdpau) in mpv. It turns out there is an Xpresent library that
integrates the xorg present extention with Xlib (which barely anyone
seems to use), so this can be added without too much trouble. The
workflow is to first setup the event by telling Xorg we would like to
receive PresentCompleteNotify (there are others in the extension but
this is the only one we really care about). After that, just call
XPresentNotifyMSC after every buffer swap with a target_msc of 0. Xorg
then returns the last presentation through its usual event loop and we
go ahead and use that information to update mpv's values for vsync
timing purposes. One theoretical weakness of this approach is that the
present event is put on the same queue as the rest of the XEvents. It
would be nicer for it be placed somewhere else so we could just wait
on that queue without having to deal with other possible events in
there. In theory, xcb could do that with special events, but it doesn't
really matter in practice.
Unsurprisingly, this doesn't work on NVIDIA. Well NVIDIA does actually
receive presentation events, but for whatever the calculations used make
timings worse which defeats the purpose. This works perfectly fine on
Mesa however. Utilizing the previous commit that detects Xrandr
providers, we can enable this mechanism for users that have both Mesa
and not NVIDIA (to avoid messing up anyone that has a switchable
graphics system or such). Patches welcome if anyone figures out how to
fix this on NVIDIA.
Unlike the EGL/GLX sync extensions, the present extension works with any
graphics API (good for vulkan since its timing extension has been in
development hell). NVIDIA also happens to have zero support for the
EGL/GLX sync extensions, so we can just remove it with no loss. Only
Xorg ever used it and other backends already have their own present
methods. vo_vdpau VO is a special case that has its own fancying timing
code in its flip_page. This presumably works well, and I have no way of
testing it so just leave it as it is.
Unfortunately there's a certain company that makes graphics drivers that
are harder to deal with. The next commit aims to implement presentation,
but some empirical testing from users show that it's actually broken.
Give up and just tap into Xrandr so we can figure what drivers (or well,
providers by the extension terminology) are driving the screen.
Basically if we find intel, amd, or radeon, assume it's a Mesa driver.
If we find nvidia, then it must be nvidia. This detection requires randr
1.4 (which means using presentation in mpv secretly depends on randr
1.4), but this protocol version is nearly a decade old anyway so
probably 99.9% of users are fine. Do the version query check and all
that anyway just to be on the safe side.
Wayland had some specific code that it used for implementing the
presentation time protocol. It turns out that xorg's present extension
is extremely similar, so it would be silly to duplicate this whole mess
again. Factor this out to separate, independent code and introduce the
mp_present struct which is used for handling the ust/msc values and some
other associated values. Also, add in some helper functions so all the
dirty details live specifically in present_sync. The only
wayland-specific part is actually obtaining ust/msc values. Since only
wayland or xorg are expected to use this, add a conditional to the build
that only adds this file when either one of those are present.
You may observe that sbc is completely omitted. This field existed in
wayland, but was completely unused (presentation time doesn't return
this). Xorg's present extension also doesn't use this so just get rid of
it all together. The actual calculation is slightly altered so it is
correct for our purposes. We want to get the presentation event of the
last frame that was just occured (this function executes right after the
buffer swap). The adjustment is to just remove the vsync_duration
subtraction. Also, The overly-complicated queue approach is removed.
This has no actual use in practice (on wayland or xorg). Presentation
statistics are only ever used after the immediate preceding swap to
update vsync timings or thrown away.
Technically this was wrong. If you passed -Dvdpau=enabled but did not
have x11 (a requirement for this), the build would silently just not
build the vdpau VO. The correct behavior is for it to be a hard error.
Accomplish this by using the require function and making sure that x11
is indeed being used before attempting to find the library.
In win32 build, if libass and libfontconfig appear after libmingwex
during linking, crash happens whenever fontconfig calls to opendir().
Moving them before ffmpeg makes sure they always appear first.
More info on https://github.com/shinchiro/mpv-winbuild-cmake/issues/217.
The first set iterates through all standard FFmpeg layouts and
checks that those which fit MP_NUM_CHANNELS succeed.
The second set iterates through built-in named channel layouts,
and attempts to convert them to AVChannelLayouts.
This is the new FFmpeg channel layout structure, which now
combines channel count and layout into a single location.
Only unspecified (channel count only) and native (channel layout
mask based) layouts are currently supported for the initial move
towards non-deprecated APIs.
This shouldn't have mattered but apparently qtile is unable to get the
app id if you set it after the initial surface commit. Wayland is a mess
anyway so just shuffle this around so that the frame callback and
surface commit are the last things registered in vo_wayland_init. This
works around qtile and, in theory, doesn't appear to break anything
else. Fixes#10280.
Some wayland compositors (i.e. weston) get extremely picky about
committed buffer sizes not matching the configured state. In particular,
weston throws an error on you if you attempt to launch with
--window-maximized and use opengl (vo_vaapi_wayland actually errors as
well in this case, but that's a different issue). The culprit here is
actually wl_egl_window_create. This creates an initial buffer at the
sizes passed in the arguments which is what weston doesn't like.
Instead, move the egl_window creation call to the resize function. This
ensures that mpv is using the size obtained via the toplevel event, and
it should always be the buffer size we want.
The `absolute` value was incorrectly labelled as the default instead of
the value named `default`, which was somewhat confusing. When the newer
default option was added in 679e410 it seems like wm4 forgot to remove
the label in the manual on the previous default.
TL;DR: previously a JavaScript VM was created + destroyed whenever
a sub track was initialized, even if no jsre filter was set.
Now a JS VM is created only if jsre filters were set.
Sub filters are initialized once when a subtitle track is chosen, and
then whenever the sub track changes or when some sub options change.
Sub filters init is synchronous - playback is suspended till it ends.
A filter can abort init early (get disabled) depending on conditions
specific to each filter. The regex and jsre filters aborted early
if the filter is disabled (default is enabled) or if the track is not
ass (relativey rare, e.g. bitmap subs).
The init then iterates over the filter strings, and if the result is
empty (common - no filter was added, but also if all strings failed
regex init) then it's also aborted during init.
While this iteration step is cheap with filter regex, with jsre it
requires instanciating the JS VM (mujs) in advance in order to parse
the filter strings at the list, and the VM is then destroyed if the
list ends up empty.
This VM create+destroy is fast but measurable (0.2 - 0.7 ms, slowest
measured on 2010 MacBook Air), but can be avoided altogether if we
check that the filter list is not empty before we create the VM.
So now we do just that.
This way mingw-w64 becomes the first CI workflow to build gpu-next.
Unfortunately, currently neither wscript or meson has gpu-next or
libplacebo-next as an option that one can require.
This was actually always bugged, but we just got lucky that compositors
ignored it. The egl window was created only using wl->geometry's
coordinates but those do not include the scale factor. So technically,
the initial window creation always had the wrong size (off by whatever
the scaling factor is). The resize call later fixes it because that
correctly uses wl->scaling so in practice nothing bad was seen.
wlroots's master branch has started sending an error in this case
however and this is what trips it. Fix it correctly by using the scale
factor. This is what cd3b4edea0 tried to
fix (but was incorrect).
cd3b4edea0 is not correct and had some
unexpected breakage with geometry/resizing. Rather than completely
revert it, this commit restores the set_surface_scaling call as well as
rearranges some other things in the wayland init/reconfig process to
make it simplier. The next commit properly fixes what
cd3b4edea0 tried to fix.
Just a couple of small changes. First, the obvious one is to remove the
bogus wl->window_size = wl->vdparams; line in the configure conditional.
The reconfig always unconditionally sets the window_size here so there's
no need to duplicate it. The more important change is to remove the
usage of set_surface_scaling. This function is just to handle when
scaling changes and for setting the initial scale, it was called in the
reconfig. This, however, causes some weird issues in the latest
sway/wlroots where it can try to divide a buffer by an inappropriate
scale factor. This is possibly due to some weird ordering of events and
only occured in opengl for some reason.
Luckily, it turns it out it's not neccessary to set the scaling here at
all. The surface enter event is already setup to handle scale changes.
On an HIDPI display, mpv will initially assume a scale of 1 but the
surface actually enters the wl_output, it will automatically readjust
and resize itself to the appropriate scale value. This works on the
initial launch of the mpv window as well, so there's no need to special
case this in the reconfig event. This has the nice bonus of avoiding
that sway/wlroots issue as well since the buffer_scale is set much
later. Fixes#10263.
One downside of this approach is that it bypasses the mixer cache, but
while this is not ideal for performance reasons, the status quo is also
simply broken so I'd rather have a slower implementation that works than
a faster implementation that does not.
And as it turns out, updating the OSD state and invalidating the mixer
cache correctly is sufficiently nontrivial to do in a clean way, so I'd
rather have this code that I can be reasonably certain does the right
thing.
Fixes#9923 as discussed. Also fixes#9928.
This is mainly for other user scripts that may conflict with the osc
logo in some way. Although it is possible to listen for
shared-script-properties, this has many edge cases that could easily pop
up. A user could want other OSC things to happen at the same time (say
osc-message). They just don't want the logo. The idlescreen option
disables all idlescreen related things (including the santa hat) if it
is set to "no". A new script message (osc-idlescreen) is also added so
users can easily toggle the value (passing "cycle" or just explictly
setting "yes" or "no"). Some more discussion on this is found in the
below github issues.

Apparently _t names are reserved, and in this case it wasn't very
useful anymore (it was useful while developing it, but this code is
almost 10 years old now).
Fixes a compilation error on Solaris.
The wayland stuff is designed to update/rescale itself whenever the
wl_output scale changes. This is great, but vo_vaapi_wayland should not
actually attempt to handle any hidpi stuff. The point of this VO is to
hand off as much to the compositor as possible, so we do want the
compositor to do the scaling here (enjoy your bilinear). This fixes some
incorrect rendering that could occur with scaling values not equal 1 due
to mismatches between buffer coordinates and the surface local
coordinates. It also eliminates the need to specify
--no-hidpi-window-scale on hidpi displays (has the same practical
effect).
A bad person (AKA me) merged this stuff without paying close enough
attention to the code style. Reformat this to be in-line with the rest
of the wayland code and general mpv style (braces for functions on the
next line, horizontally aligning arguments, some cosmetic cleanups for
wayland_common.h, etc.).
So it turns out that mpv already has an mp_tag_str which makes a
readable string out of fourccs (drm formats are these).
drm_format_string, on the other hand, has a ton of baggage with having
to check different libdrm versions for certain headers, adding
compile-time defines (because there are no version defines in the libdrm
headers), etc. It's a lot simpler to just use what mpv already has and
it returns what you actually care about: i.e. is this format supported
or not. Fixes https://github.com/mpv-player/mpv-build/issues/184
This driver makes use of dmabuffer and viewporter interfaces
to enable efficient display of vaapi surfaces, avoiding
any unnecessary colour space conversion, and avoiding scaling
or colour conversion using GPU shader resources.
If the player is started with --idle and the osc-tracklist script-message
is called then the tracks_osc table will be nil,
which caused the OSC to crash due to attempting to index a nil value.
This appears to be because the osc_tracklist variable is both
initialised and updated by (ultimately) the render() function, which
is not run when the player is idling.
Rather than mess with the existing OSC logic it's easier to either
add this single check, or alternatively to initialise the the tracks_osc
table somewhere before this.
Both mpv's main function and the client API use mp_initialize to start
up. In general, these work the same however the client API had one
slight, unnecessary limitation: you can't start it up with idle=no. In
practice, the libmpv profile (used with the client API) sets idle to
yes, so it's rarely encountered, but there's no particular reason why
this policy needs to be enforced. It turns out that mp_initialize does a
quick check to see if there are any entries in the playlist and if idle
mode is set. If not, it prints the help message and exits. Basically,
it's just the part that handles the terminal message when you type "mpv"
with no arguments. Unfortunately with idle=no, the client API also hits
this code path, exits prematurely with 1 and thus returns an API error.
Fortunately, the fix is very simple. If the client API is used instead
of the "normal" mpv executable, then the mp_initialize function gets a
NULL for the options argument. When starting mpv from the terminal (when
you would want to see the before mentioned help text), there will always
be at least an argv[0] (the mpv executable name itself) so we can
reliably distinguish between the two. The other case where there could
be no argv is if the pseudo-gui profile is used, but this always
enforces idle so we don't have to worry about it either. In other words,
with this combination of conditions (options, no idle, and no playlist
entries), we can be sure this is from a user calling mpv in the terminal
with no arguments. Therefore, other cases can be allowed which means
client API users can initialize with idle=no. Fixes#10162.
Normally with the keep-open option, mpv is supposed to set the
eof-reached property to true so clients can possibly do interesting
things at this step. However, there was actually an edge case where this
property notification did not occur. If you use keep-open and then seek
in the file past the end (so mpv stops), property notification is not
actually sent in this case. Internally, mpv does a very exact seek at
this step which also ends playback, but it does not set STATUS_EOF to
the ao and vo before the core idle state is updated. To fix this edge
case, it's simply just a matter of explictly setting STATUS_EOF after
seek_to_last_frame in handle_keep_open. This logic will only ever
trigger if keep-open is being used and the seek goes past the end of the
file, so we know that there will always be an EOF here.
5774ce759a added the new output name event
and used them for the --fs-screen-name option. It turns out that the
display-names property could also make use of these names, so go ahead
and use output->name in this case if we have them. If not, fallback to
output->model like before.
Windows is weird and symbols weren't actually being exported. This is
because __GNUC__ is defined and picked up in the conditional, but
__attribute__((visibility("default"))) doesn't actually export anything
to the dll. Instead, just check if we have win32 defined first and then
always set __declspec(dllexport). Fixes#10171.
ffmpeg 5.1 adds support for IPFS (the ipns:// and ipfs:// protocols).
This patch enables those protocols to be fist-class citizens in mpv.
Thus allowing for playing IPFS resources on mpv like:
"mpv ipfs://QmbGtJg23skhvFmu9mJiePVByhfzu5rwo74MEkVDYAmF5T"
Some compiler flags were passed to mpv in order to get it to build as a
gui application on windows. However on the meson build, this always
resulted in mpv being built as a console application. This is because
the function for making executables in meson specifically has a kwarg
called win_subsystem* which defaults to 'console'. That always added
link arguments at the end which compiled mpv.exe as a console
application. The correct thing to do is to remove all of the
subsystem-related flags in the meson build and use the win_subsystem
kwarg as intended by setting it to 'windows,6.0'. For mpv.com, we can
remove the -Wl,--subsystem,console flag since meson will set this by
default in that executable. This makes mpv.exe function correctly and
open with the pseudo-gui while mpv.com acts as a console wrapper.

These values and options were simply never looked at in the drm egl
context. This pretty much is just a copy and paste of what is in vo_drm.
Fixes#10157.
09ea3a424f moved the console above the OSC when it is visible so they
don't overlap, but only changed the first ass:pos() call and forgot to
update the second one, which redraws the cursor on top of the text, so
when both the OSC and the console are visible, a second cursor is drawn
on the OSC. You have to type past where the buttons are to notice it.
This commit synchronizes the position of the 2 ASS events.
Allow screenshot-high-bit-depth=yes to work with JPEG XL
screenshots when screenshot-sw=no is set. They already work
as expected when screenshot-sw=yes is set, but this allows
the hardware screenshots to work this way too.
Since 2018, wl_surface_damage_buffer has been explicitly preferred and
recommended over wl_surface_damage*. mpv was still using the old
function in a couple of spots. The only difference is that we need to
pass buffer coordinates instead of surface coordinates. In vo_wlshm,
this is done by using vo->dwidth/vo->dheight since that is always used
whenever wl_buffers are created. In the case of the cursor surfaace, we
actually already passed buffer coordinates to it (img->width/height)
which was probablly technically wrong with wl_surface_damage, but it
doesn't really matter in practice. This requires bumping wl_compositor
to version 4 which is no problem since this dates back to 2015*.

Add Jpeg XL as a possible output format for screenshots, which
should make it possible to take fast screenshots with much better
quality than JPEG, or take lossless high-bit-depth screenshots
with lower file sizes than PNG.
It is possible for vo_gpu_next to attempt a resize before the windowing
backend is fully initialized. In practice, this can happen on wayland
which means libplacebo attempts a 0x0 resize. Depending on the API, a
0x0 resize may be allowed (vulkan or d3d11), but libplacebo just returns
a 0 in this case which mpv doesn't do anything with anyway. In the case
of opengl, this usage is explictly forbidden and will result in a
warning which may confuse users. Solve this by just not trying a resize
if dwidth and dheight in the vo are not available. Fixes#10083.
Recently, git patched a CVE which makes it much more strict about
different users operating on directories they don't own. For us, this
causes breakage with version.sh and version.py since they both run a git
describe command to fetch the commit hash. Currently, this only affects
the tumbleweed container (likely because it was recently changed) and
thus the git describe command always errors out. Workaround this by just
explictly adding the mpv directory as a safe directory for git.
- Say built-in which is more common than builtin
- Move "By default" because only the key to open the console is
customizable, and fix the punctuation and case of the sentence
- ` opens the console, not ´
- Remove the sentences that explains which user script console.lua is
based on since it's no longer relevant now that the console has been
part of mpv for over 2 years.
Now that a separate --cover-art-whitelist option exists, files like
cover.jpg are loaded even without setting --cover-art-auto to fuzzy, so
only load files that have exactly the media filename by default, since
fuzzy loading is probably more likely to load unwanted images than to
load cover art that the user intended to display, especially if you play
audio files with a short filename like a.mp3.
This allows more fine grained control over which cover art to load. With
--cover-art-auto=exact and --cover-art-whitelist=yes, you can now load
cover art with the exact media filename and the whitelisted filenames,
but not cover art that contains the media filename
(--cover-art-auto=fuzzy).
This adds a section to the documentation to explain how resuming
playback works, and in particular it explains how it affects which
playlist entry mpv starts playing from, since this feature was only
implied in the --playlist-start documentation.
It also groups the documentation of the watch later options together to
make them easier to find.
draw_image is an old API that was deprecated long ago. However when
wlshm was originally added, it used draw_image. There's no particular
reason for this and it can trivially be switched to draw_frame instead.
This has some real advantages (notably --vo=wlshm --idle --force-window
actually works).
This fixes build failures with avcodec 58.113.100 or before,
matching FFmpeg release versions 4.0 to 4.3.
This flag was added in between avcodec 58.113.100 and 58.114.100
during the FFmpeg 4.4 development cycle. It lacks its own version bump,
so instead a check for the define is utilized instead.
Additionally, warn the user if they request GPU film grain with
too old of an FFmpeg.
Fixes#10088
The VO is available during decoder initialization mostly for direct
rendering purposes, so if f.ex. a complex filter chain is utilized,
there is no video renderer information available via
mp_filter_find_stream_info during creation of the decoder filter.
Thus, check for whether the VO is available before attempting to
check the capabilities flag from it.
Additionally - to simplify logic - makes explicitly requesting GPU
film grain to always disable decoder film grain functionality. The
warning is still shown if the VO is available and no support for
film grain application is available.
Fixes#10079
In wayland 1.20.0, a couple of new events, name and description, were
added to the interface. Description is not particularly useful, but name
returns back nice names for the output like "DP-1" and so on. It makes
sense to use these for fs-screen-name and prefer them over the model
name (old way of doing it) if they are available. The only problem is
that 1.20.0 is pretty new so old distros aren't going to have it anytime
soon. Deal with this by adding some defines.
Because wayland is a special snowflake, mpv wound up incorporating a lot
of logic into its render loop where visibilty checks are performed
before rendering anything (in the name of efficiency of course). Only
wayland actually uses this, but there's no reason why other backends
(x11 in this commit) can't be smarter. It's far easier on xorg since we
can just query _NET_WM_STATE_HIDDEN directly and not have to do silly
callback dances.
The function, vo_x11_check_net_wm_state_change, already tracks net wm
changes, including _NET_WM_STATE_HIDDEN. There is an already existing
window_hidden variable but that is actually just for checking if the
window was mapped and has nothing to do with this particular atom. mpv
also currently assumes that a _NET_WM_STATE_HIDDEN is exactly the same
as being minimized but according to the spec, that's not neccesarily
true (in practice, it's likely that these are the same though). Anyways,
just keep track of this state in a new variable (hidden) and use that
for determing if mpv should render or not.
There is one catch though: this cannot work if a display sync mode is
used. This is why the previous commit is needed. The display sync modes
in mpv require a blocking vsync implementation since its render loop is
directly driven by vsync. In xorg, if nothing is actually rendered, then
there's nothing for eglSwapBuffers (or FIFO for vulkan) to block on so
it returns immediately. This, of course, results in completely broken
video. We just need to check to make sure that we aren't in a display
sync mode before trying to be smart about rendering. Display sync is
power inefficient anyways, so no one is really being hurt here. As an
aside, this happens to work in wayland because there's basically a
custom (and ugly) vsync blocking function + timeout but that's off
topic.
The video sync logic for mpv lies completely within its core at
essentially the highest layer of abstraction. The problem with this is
that it is impossible for VOs to know what video sync mode mpv is
currently using since it has no access to the opts. Because different
video sync modes completely changes how mpv's render loop operates, it's
reasonable that a VO may want to change how it renders based on the
current mode (see the next commit for an example).
Let's just move the video sync option to mp_vo_opts. MPContext, of
course, can still access the value of the option so it only requires
minor changes in player/video.c. Additionally, move the VS_IS_DISP
define from to player/core.h to common/common.h. All VOs already have
access to common/common.h, and there's no need for them to gain access
to everything that's in player/core.h.
A bit of a personal pet peeve. vulkan, opengl, and wlshm all had
different methods for doing wayland's "check for visibility before
drawing" thing. The specific backend doesn't matter in this case and the
logic should all be shared. Additionally, the external swapchain that
the opengl code on wayland uses is done away with and it instead copies
vulkan by using a param. This keeps things looking more uniform across
backends and also makes it easier to extend to other platforms (see the
next couple of commits).
This lets us remap various messages which might now be happening at
each frame onto the trace level, thus unaffecting the initial debug
log level.
Additionally - thanks to this ability - the previously globally denied
message queue abandonment messages can now be handled and mapped to
trace log level, as on that log level they may be of use.
Recommended by rossy and based on his libplacebo commit
6d72f6445566eddb0493447d0bda72d98a99d40c .
Instead of always having the reference outside of calling resize,
request a backbuffer at start and relieve the backbuffer at
submission for presentation.
Query the description of the swap chain, which should in all theory
contain the format of the backbuffer. Then utilize a newly added
ra_d3d11 function to map the format to an ra_format. After that,
utilize the depth of the first plane of the format, as previously.
This makes use of the new frame acquire/release callbacks to hold on to
hwdec images only as long as necessary. This should greatly improve the
smoothness/efficiency of hwdec interop, by not holding on to them for
longer than needed.
This also avoids the need to pool hwdec mappers altogether.
Should fix#10067 as well, since frames are now only mapped when we
actually use them.
9a7b2015e1 added the --screen-name option
for x11, but it was unfortunately broken. The commit does correctly
handle vo_x11_update_screeninfo and select the correct screen. However,
vo_x11_sizehint was missed. Specifically, the force_pos bool was always
false because it only took into account --screen being set and not
--screen-name. To fix this, just add an extra condition to the force_pos
bool so it becomes true if there's a string in --screen_name. Fixes
issue #9877.
Previously on wayland, it would result in an egl config with only 2 alpha
bits, which technically matches what was requested, but is not very useful.
Fixes#9862
Variable Refresh Rate (VRR), aka Freesync or Adaptive Sync can be used
with DRM by setting the VRR_ENABLED property on a crtc if the
connector reports that it is VRR_CAPABLE. This is a useful feature
for us as it is common to play 24/25/50 fps content on displays that
are nominally locked to 60Hz. VRR can allow this content to play at
native framerates.
This is a simple change as we just need to check the capability
and set the enabled property if requested by the user. I've defaulted
it to disabled for now, but it might make sense to default to auto
in the long term.
The field has been deprecated, yet the upcoming new default is not yet
the default. Thus, until lavc major hits 60 and the default behavior
finally gets changed, we have to explicitly set the field's value.
The deprecation had already been handled by adding the required
version limitation for this code in bbbf3571ed ,
this change merely just removes the warning which would otherwise
appear until lavc major version gets bumped to 60.
this field is used only in a special vo draining edge case.
switching to an atomic reduces osd->lock contention
between the mpv core (in write_video) and vo threads
which are managing osd rendering manually (such as vo_rpi).

Pulling in <libplacebo/utils/libav.h> in particular triggers the
notorious _av_vkfmt_from_pixfmt linking issue when FFmpeg is built
without Vulkan support.
When I introduced the concept of lazy loading of hwdecs by img format,
I did not propagate the probing flag correctly, leading to the new
normal loading path not runnng with probing set, meaning that any
errors would show up, creating unnecessary noise.
This change fixes this regression.
FFmpeg recently split version.h into version.h and
version_major.h, and no longer automatically includes
version.h in avcodec.h (and the other libraries). This
should allow mpv to build against ffmpeg git master. See
FFmpeg/ffmpeg@f2da2e1458
These headers are not new, so their inclusion should not affect
backwards compatibility.
As found out by @philipl, failing to pass this from the VkInstance to
the VkDevice is bad style. We might want to override the get_proc_addr
pointer in the future.
20c4036daa switched to hiding all symbols
by default and exporting the ones we want with MPV_EXPORT.
However, the mpv_stream_cb_add_ro function was missed and it is part of
the client API. Export it too. Fixes#9971.
Our logging here today is very poor. We don't make it clear what
formats we are probing, or even that a certain format failed in most
cases. In the case where we do log the error, we don't make it clear
which format it was that failed.
The end result is that we have no idea what the possible and final
format spaces are, which makes it very hard to debug whether things are
working correctly, or to work on supporting additional formats.
The documentation's current discussion of hwdec usage is out of date,
and unnecessarily pessemistic when applied to modern hardware. The
reality is that modern APIs on modern hardware produce reasonable
results and there's no need to pretend otherwise. The current language
that tries to drive people away from using hwdecs at all leads to them
making bad choices when they do try to use it.
Let's also make it clearer that users should use vo=gpu with hwdecs
rather than vo=vaapi or vo=vdpau. Even the existing admonitions have
proven insufficient, so let's strengthen that language.
This code fails if we have DR buffers, but none of them correspond to
the current frame. Normally only happens if e.g. changing the decoder at
runtime, since DR buffers are not properly reinit in that case.
(Arguably a separate bug)
The current map_frame() code fails to clean up after itself on the
failure paths. But if map_frame returns false, no cleanup code is ever
attempted. Add the relevant calls to clean up state manually,
throughout.
So, turns out the approach in 7f67a553f doesn't work for all codecs. In
particular, sometimes lavc will internally allocate a new AVBuffer that
just points at the old AVBuffer but has a different opaque field for
some reason. In these cases, the DR metadata doesn't survive the
round-trip through libavcodec.
I explored several alternative ways of solving this problem, including
adding new mp_image fields, but in the end none of them survived the
round-trip through AVFrame and back. The `priv` and `opaque` fields
in respectively `mp_image` and `AVFrame` are also too heavily overloaded
to be of much help.
In the end, bite the bullet and use the same approach as done in
`vo_gpu`, which is to just keep track of a list of all allocations. This
is a really ugly way of doing things IMO, but ultimately, completely
safe.
Previously, when mpv was invoked with unsupported hwdec value, such
as --hwdec=foobar, there was no indication that it doesn't exist.
The reason it's not validated during options parsing is that the name
is only evaluated when selecting hwdec for actual decoding, by
matching it against runtime list of names from ffmpeg.
Additionally, when selecting hwdec for decoding, matching the name
came after filtering by codec, hence overall never-matched-name did
not necessarily indicate it's unsupported (doesn't exist at all).
Now we check the name before filtering by codec, and when done,
warn if no hwdec with that name exists at all.
This means that an unsupported name will now generate such warning
whenever we try to choose a hwdec, i.e. possibly more than once.
It's much better than no notification at all, and arguably adequate
for a sort of configuration error (linked ffmpeg has no such hwdec
name) which we don't validate during option parsing.
Some decoders, notably hevcdec, will unconditionally memset() the entire
AVBufferRef based on the AVBufferRef size. This is bad news for us,
since it also overwrites our `struct dr_buf`.
Rewrite this code to make it more robust - keep track of the DR buf
metadata in a separate allocation instead. Has the unfortunate downside
of technically being undefined behavior if `opaque` is not at least 64
bits in size, though, but avoids this issue.
Maybe there's a better way for us to unconditionally keep track of DR
allocation metadata. I could try adding it into the `mp_image` itself.
Maybe on a rainy day. For now, this works.
Fixes#9949

Previously only status<0 was considered as error, but status>0 is
also an error (the process exit code). Change to status != 0.
This likely makes little to no difference in practice, because if
stdout is empty or can't be parsed as JSON then it's considered
an error anyway, but still, this is more correct.
Also, on error, add the complete subprocess result to the verbose log.
There are two major ways of going about this:
1. Expose the native ra_gl/ra_pl/ra_d3d11 objects to the pre-existing
hwdec mappers, and then add code in vo_gpu_next to rewrap those
ra_tex objects into pl_tex.
2. Wrap the underlying pl_opengl/pl_d3d11 into a ra_pl object and expose
it to the hwdec mappers, then directly use the resulting pl_tex.
I ultimately opted for approach 1 because it enables compatibility with
more hardware decoders, specifically including ones that use native
OpenGL calls currently. The second approach only really works with
cuda_vk and vaapi_pl.
I was initially hesitant to link to an external article from the manpage
but a lot of other places in the man page already do something like
this, and it really makes more sense to have this as a wiki article
rather than trying to keep the manpage up-to-date by hand, since this
evolves quickly and the two are expected to converge over time.
This avoids decoding/caching more frames in advance than necessary. In
particular, this is very important for hwdec, which generally can't have
too many decoded frames in a pool at the same time.
So I can reuse it in vo_gpu_next without having to reinvent the wheel.
In theory, a lot of the stuff could be made more private inside the
hwdec code itself, but for the time being I don't care about refactoring
this code, merely sharing it.
We don't need to hold on to buffers longer than necessary. Doesn't
matter for vo_gpu but greatly matters for vo_gpu_next, since it persists
hwdec mapped textures for longer periods.
Unfortunately, only provides benefits for hwdecs which do explicit
copies in their decode path, which currently just means cuda and
d3d11va.
There's really nothing vulkan-specific about this hwdec wrapper, and it
actually works perfectly fine with an OpenGL-based ra_pl. This is not
hugely important at the time, but I still think it makes sense in case
we ever decide to make vo_gpu_next wrap OpenGL contexts to ra_pl instead
of exposing the underlying ra_gl.
Easiest way is by just using a designated struct initializer. If we
don't, `p->images` ends up inheriting random data, which leaks into e.g.
eglDestroyImageKHR.
It's a small miracle this never blew up before. Or maybe it did. Who
knows.
A few years ago, in 25e70f4743, we
disabled the vavpp deinterlacing auto-filter on the basis that it
caused crashes on _some_ hardware with _some_ driver version(s). But
since then, the situation has improved. There is still a limitation
where you can't turn deinterlacing on on the fly with AMD, but it
doesn't crash anymore (That is #7388).
So, given that AMD users have to set up the deinterlacing filter
manually either way, let's re-add the auto-filter for Intel users.
Some youtube_dl extractors retrieve URLs which contain other URLs
inside of them, for example Funimation, like this:
https://example.com/video?parameter=https://example.net/something
The url_is_safe function uses a pattern to match the protocol at the
start of the URL. Before this commit, this pattern was not compliant
with the URL spec (see the definition of "A URL-scheme string"):
https://url.spec.whatwg.org/#url-writing
Therefore it would match any characters, including "://", until the
last occurence of "://" in the string. Thus the above URL would match
https://example.com/video?parameter=https
which is not in safe_protos so the video will not play.
Now the protocol can only start with a letter and only contain
alphanumerics, "." "+" or "-" as the spec says, so it will only match
the first protocol in the URL ("https" in the above example.)
Previously the URL also had to contain "//" after the ":". Data URLs

libplacebo v198 fixed this properly by adding the ability to flip planes
directly, which is done automatically by the swapchain helpers.
As such, we no longer need to concern ourselves with hacky logic to flip
planes using the crop. This also removes the need for the OSD coordinate
hack on OpenGL.
These helpers, for some reason, decided to round the returned values up
to multiples of the nearest plane alignment. This logic makes no sense
to me, and completely breaks any sort of oddly-sized mp_image.
This logic was introduced, presumably in error and without real
justification, as part of a major refactor commit (caee8748), As far as
I can tell, removing it again doesn't regress anything.
Fixes several serious bugs including buffer underflows and GPU crashes
in vo_gpu and vo_gpu_next.
Page 2 displays the frame timing info for each type (currently "Fresh"
and "Redraw"), but since they're unordered keys of a map, their
iteration order and hence their order on screen could (and did) change
depending on $things, which was annoying.
haasn thinks none of them should be considered more important (and
therefore maybe worthy of being displayed on top), so we go with
lexicographic order, which currently means that "Fresh" is first.
Fixes#9901
This fixes two potential divisions by 0 at generate_graph(...):
- If v_avg is (given and) 0.
- if v_max is 0.
The former doesn't seem to happen in practice because v_avg is only
used at one generate_gpah call, where it's apparently not 0.
The latter triggers if all the graph values are 0 (hence v_max is
also 0).
The implication of these divisions by 0 is an invalid y-value which
ends up at the ASS coordinates string for the graph inner content.
On linux the value ends as "nan" (luajit) or "-nan" (lua 5.1/5.2), and
on Windows it's "nan" (luajit) or "-1.#IND00" (lua 5.1/5.2), maybe due
to msvcrt's snprintf.
All these strings are wrong as ASS numbers, but due to luck in how
libass parses the coordinates, "nan" and "-nan" result in empty graph
(which looks OK for "all values are 0"), while "-1.#IND00" is parsed
as -1, which breaks the graph rendering (affects other graphs too).
One example of "all values are 0" is at page 0 (internal performance
graphs) on Windows - because the cpu metrics don't work.
So this fixes at least page 0 on Windows with lua 5.1/5.2.
While at it, move the scale calculations to one place, which now
avoids division by 0, instead of duplicating this calculation.
In the future, we can consider improving the generate_graph API:
- It needs one peak value, but takes 3 (v_max, v_avg, scale) which
are meshed into one final value.
- v_avg is only used in 1 of 6 call sites, but at the middle of the
arguments, so all other call sites need to pass explicit "nil".
- "scale" is arbitrary and used to leave some space at the top of the
graph. 5 places use 0.8, one uses 0.9. Could probably be unified.
Render subs at the output resolution, rather than the video resolution.
Uses the new APIs found in libplacebo 197+, to allow controlling the OSD
resolution even for image-attached overlays.
Also fixes an issue where the overlay state did not get correctly
updated while paused. To avoid regenerating the OSD / flushing the cache
constantly, we keep track of OSD changes and only regenerate the OSD
when the OSD state is expected to change in some way (e.g. resolution
change). This requires introducing a new VOCTRL to inform the VO when
the UPDATE_OSD-tagged options have changed.
Fixes#9744, #9524, #9399 and #9398.
The stop-screensaver option is currently limited to a simple yes/no
option. While the no option does always disable mpv trying to stop the
screensaver, yes does not mean the screensaver is always stopped. The
screensaver will be enabled again depending on certain conditions (like
if the player is paused). Simply introduce a new value for this option,
always, which does exactly what the name implies: the screensaver will
always be disabled.
- Make it clearer that playback_only affects subprocess' behavior when
the playback of the current playlist entry terminates, rather than
when mpv quits.
- Explain when status is positive and when it is negative.
- Replace "exited gracefully" in status' and error_string's
documentation with "terminated normally" so it can't be misinterpreted
as exiting successfully.
- Reword the playback_only warning
Historically, we have treated hwdec interop loading as a completely
separate step from loading the hwdecs themselves. Some hwdecs need an
interop, and some don't, and users generally configure the exact
hwdec they want, so interops that aren't relevant for that hwdec
shouldn't be loaded to save time and avoid warning/error spam.
The basic approach here is to recognise that interops are tied to
hwdecs by imgfmt. The hwdec outputs some format, and an interop is
needed to get that format to the vo without read back.
So, when we try to load an hwdec, instead of just blindly loading all
interops as we do today, let's pass the imgfmt in and only load
interops that work for that format. If more than one interop is
available for the format, the existing logic (whatever it is) will
continue to be used to pick one.
We also have one callsite in filters where we seem to pre-emptively
load all the interops. It's probably possible to trace down a specific
format but for now I'm just letting it keep loading all of them; it's
no worse than before.
You may notice there is no documentation update - and that's because
the current docs say that when the interop mode is `auto`, the interop
is loaded on demand. So reality now reflects the docs. How nice.
Pass channel volumes to `pw_stream_set_control` as array.
This is correct calling conventions and prevents
right channel muting every time ao-volume property is changed.
Terminate `pw_stream_set_control` calls with 0.
This is an annoying special case only really needed because of the
`vflip` filter. mpv handles this by directly adjusting the plane
transform. The libplacebo API, unfortunately, does not allow passing the
required information for this to work smoothly.
Long-term I plan on adding support for plane flipping in libplacebo
directly, but for the meantime, we will have to work-around it by moving
the flipping to the whole-image `crop` instead. Not an ideal solution
but better than crashing.
Fixes#9855
We're getting bug reports that the recent change to add extra usage
flags to swapchain buffers (for gpu-next) breaks mpv on some Windows 7
systems, and it seems like this is only happening with flip-model
swapchains.
Creating swapchains with DXGI_USAGE_UNORDERED_ACCESS should be valid. At
least, it's not specifically disallowed, unlike some other flags[1]. So,
just disable it for flip-model swapchains in Windows 7, rather than
disabling it everywhere.

See the previous commit for the full explanation. Basically, luajit 2.0
has a bad pc file on macos that causes libmpv to fail during build. The
workaround was, if the os was darwin and luajit was found, to save a
full luajit dep and a partial luajit dep with the link args removed. The
partial dep was used for compiling libmpv, and the full dep was used for
the actual mpv executable. This worked and was needed for the CI to pass
but it sucked. Since the previous commit now makes the CI grab lua 5.1,
we don't need all this crap anymore. Just delete it and treat the
dependency normally.
This does effectively mean that building libmpv with luajit 2.0 on macOS
will no longer work with the meson build. However libraries not being
built correctly is not a mpv-specific issue. The waf build will succeed
for some reason, but it has known issues and it would be better if it
just failed honestly. An upstream developer said years ago that that
macOS users should use the 2.1 branch (and there's no release of
course). In any case, no macOS user should be building mpv with luajit
2.0, so we shouldn't be going out of our way to support this.
https://github.com/mpv-player/mpv/issues/7512https://github.com/LuaJIT/LuaJIT/issues/521#issuecomment-562999247
LuaJIT is still actively developed, but upstream is allergic to making
new releases for whatever reason. The last tagged release was in May of
2017, so we probably shouldn't expect a new release anytime soon. Now
for mpv, this doesn't really matter except in the case of macOS where
2.0.5 is actually a bit broken (and of course the CI uses luajit). More
specifically, the 2.0.5 pc is broken and has a "-pagezero_size 10000"
flag which causes libmpv to fail (only executables are allowed to use
this). This magically works on waf. It's possible that it just happens
to ignore the link arguments. However on the meson build, this is broken
and led to a really ugly hack using a partial dependency so both mpv and
libmpv succeed. Fortunately, the 2.1 luajit branch fixes this.
Unfortunately, there's no actual release.
Instead, just use Lua 5.1. Note that lua 5.1 is technically deprecated
in homebrew, but the chances of this going away is pretty slim since
everyone knows that new lua versions are not backwards compatible.
Anyways, using 5.1 works fine and lets us get rid of a terrible hack in
the meson build. People really shouldn't be using 2.0 LuaJIT anyway.
We have a few examples with vf=rotate=90, but libavfilter's rotate
accepts radians - not degrees, so a value of 90 is valid but misleading
because it's not 90 degrees.
Change the value of 90 at those examples.
Also replace "vf-add=hflip" with "vf add hflip", since that example
lists commands, not options, to run.
Drag and drop in wayland is weird and it seems everyone does this
slightly differently (fun). In the past, there was a crash that
occured (fixed by 700f4ef5fa) which
involved using the wl_data_offer_finish in an incorrect way that
triggered a protocol error (always fatal). The fix involved moving the
function call to data_device_handle_drop which seemingly works, but it
has an unfortunate side effect. It appears like GTK applications (or at
least firefox) close the pipe after this function is called which makes
it impossible for mpv to read data from the fd (well you could force it
open again in theory but let's not do that). Who knows if that was the
case when that commit was made (probably not because I'd think I would
have noticed; could just be a dummy though), but obviously having broken
dnd for a major application isn't so fun (this works with QT and
chromium anyway).
Ideally one would just simply check the pipe in data_device_handle_drop,
but this doesn't work because it doesn't seem the compositor actually
sends mpv the data by then. There's not actually a defined event when
you're supposed to be able to read data from this pipe, so we wait for
the usual event checking loop later for this. In that case,
wl_data_offer_finish needs to go back into check_dnd_fd, but we have to
be careful when calling it otherwise we'd just commit protocol errors
like before. We check to make sure we even have a valid wl->dnd_offer
before trying to indicate that it is finished and additionally make sure
there is a valid dnd_action (after checking the fd, it's always set back
to -1).
This doesn't fix everything though. Specifically, sway with
focus_follows_mouse (the default) and GTK as the data source still
doesn't work. The reason is that when you do a drag and drop in sway
with that option on, a new wl_data_device.data_offer event is sent out
instantly after the drop event. This happens before any data is sent
across the fd and before mpv even has a chance to check it. What GTK
does, when getting this new data_offer event, is close the pipe
(POLLHUP). This means mpv can't read it when we reach the event loop and
thus no data is ever read and broken drag and drop. From the client
side, this isn't really fixable since the wayland protocol doesn't have
a clear indication of when clients are supposed to read from the fd and
both the compositor and data source are doing things totally out of our
control. So we'll consider this weird case, "not our bug" at least. The
rest should work.
By receiving the graphics API-specific contexts from the generic
pl_gpu instance, it is not necessary to store them separately.
As the current priv struct stores nothing else, this allows its
removal. This removal cleans up related compiler warnings regarding
unused variables in case of opengl and d3d11 being disabled in
mpv/libplacebo.
Functions to receive the underlying vulkan,gl,d3d11 structure were
added in libplacebo version 4.182. Our current requirement for
gpu-next is 4.190, and thus we can freely utilize these helper
functions.
We only wish to touch actual video frames, which should have an
allocated image attached to them, so just check the frame type
early, and exit by passing through such non-video frames to further
filters in the chain without attempting to process them.
Fixes a crash in case of non-video (EOF/NONE) frames being passed
onto the filter when the dovi option was set to false since
05ccc51d53 .
While testing support for the exotic formats used by Intel vaapi for
4:2:2 and 4:4:4 surfaces, I realised that we were enumerating all
endpoints and checking formats for them. The problem with this is
that decoding (VLD) endpoints are only a subset of what vaapi exposes.
All the encoding endpoints are there too, and there is also the
None profile that we don't care about, but which generates ffmpeg
warnings if you try and examine it.
So, let's only look at VLD endpoints. This will speed things up a
little bit and make the logging less noisy.
This speeds up chapter name access while hovering the seekbar:
- Fetch the chapter-list property using observation rather than on
every render while hovering the bar. Property access, especially
with potentially lots of values (chapters), can be expensive-ish,
and can involve locking, so the less per-render the better.
- Sort the list once (on change) to simplify the iteration logic when
searching the chapter which matches the mouse position. It's still
O(N) (no binary search currently), but with less work.
The cached sorted list is stored at the state. While there are other
places which access this property and could use this cache, for now we
don't touch them, because they're not performance-critical (on init
for the chapter markers, on ch_{prev,next} button click for OSD).
Caching properties using observation instead of using mp.get_property
can indeed speedup other places too, but it should be part of a system
rather than implemented per-property. Maybe some day.
When utils.get_user_path was added, the expand-path command didn't
exist. Now it does, so remove the C code, make it a trivial wrapper.
Keep this function for backward compat to not break scripts, but
technically it's not required anymore.
This has been the latest stable release for about half a year now. This
version in particular lets us get rid of all the deprecation warnings in
the older code. (See the following commits)
The wayland backend contains logic to detect if the window is hidden. If
so, we skip rendering as an optimization. However, if we receive
multiple resize events in rapid succession, we will send the compositor
new buffers faster than the refresh rate of the monitor. Therefore the
compositor will not send us frame events which we incorrectly interpret
as the window being hidden.
Once the last buffer has actually been rendered, the compositor sends us
a frame event. However, if at that point playback is paused, there is no
logic to restart rendering of frames that we skipped due to the above
optimization. Therefore we never send the compositor new buffers
corresponding to the new size of the window and the surface will either
be too small or too large.
The simplest solution is to always render a few frames after we receive
a resize event.
vo_gpu_next and libplacebo expect swapchain images to be able to be
blitted to, which for libplacebo on FL11_0 and up means they have to
have DXGI_USAGE_UNORDERED_ACCESS, since libplacebo uses a compute shader
to emulate certain kinds of blits. For libplacebo's benefit, set all
applicable usage flags on swapchain images.
The docs specify that the +-X+-Y geometry values position the content.
This used to work correctly but got broken at 8fb4fd9a .
Geometry size is unaffected - this only concerns position.
Commit 8fb4fd9a made it center the window rather than the content by
taking the borders into account during positioning, but forgot to make
an exception when a position is specified explicitly.
This commit adds this exception, and now if a specific position is
requested then the borders are ignored, and the content is positioned
correctly.
The code assumed that the value of the profile-restore field is
"default" for such profiles, but the C implementation is such
that the field is intentionally omitted in such case.
This resulted in incorrectly trying to restore such profiles. However,
there are no stored values with profile-restore=default, so it only
resulted in a harmless warning, but otherwise behaved correctly (i.e.
nothing is restored).
Fix the condition by taking into account that missing field means
"default", so that it doesn't try to restore in such case, and
avoid the warning.
Currently the profile-restore field is intentionally omitted if it
holds the default value (i.e. no values are stored for the profile,
and trying to restore would only warn).
See m_config_get_profiles at command.c .
a02901cae7 changed how mpv was handling
wl_surface_set_buffer_scale. It's correct in that constantly setting the
surface scale on every resize (which mpv was previously doing) is
unneccessary and not right. However, it introduced a slight regression
if someone moved a surface to a new monitor with the same resolution but
a different scale. It did not trigger a resize and thus the video would
have incorrect dimensions. A later refactor changed how things looked
inside here, but this regression wasn't fixed. A resize should always be
triggered if the scale changes in this surface event. Fixes#9426.
Mouse button event codes above `BTN_EXTRA` (the ones currently defined
in `input-event-codes.h` are `BTN_FORWARD`, `BTN_BACK`, and `BTN_TASK`)
are mapped to `MP_MBTN9` and up. (Reminder that due to historical
reasons, the names `BTN_FORWARD` and `BTN_BACK` are completely
misleading; the real forward and back buttons are `BTN_SIDE` and
`BTN_EXTRA` and are already mapped correctly by mpv.)
This functionality is analogous to what the X11 backend supports in
`video/out/x11_common.c` and what the Cocoa backend supports in
`video/out/cocoa/events_view.m`.
According to the xdg-shell protocol spec, a 0x0 size from the compositor
means that "the client should decide its own window dimension". We were
not doing this correctly. What should happen is that mpv should simply
reuse the old window size if it is not maximized or fullscreened. This
should work on all (reasonably recent) versions of mutter and an
compositor that follows the spec.
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/blob/main/stable/xdg-shell/xdg-shell.xml#L1050
So actually according to the xdg-shell spec, a 0x0 resize is meant to
indicate that "the client should decide its own window dimension".
Previously, this just accidentally worked. In mutter 41.3, they changed
how 0x0 resizes were sent and what actually happened was that mpv tried
to resize itself to 0x0. This was obviously broken, so the reverted
commit naively just ignored 0x0. It actually seemed to work, but it
ended up breaking older versions of mutter. It's also not exactly the
correct fix so it deserves a revert.
This reverts commit d16defac27.
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/blob/main/stable/xdg-shell/xdg-shell.xml#L1050
This define was always just a stopgap for that two month period (August
2021 - October 2021) where the bytes_read field in ffmpeg was completely
missing. Before that time, it was a private member in a struct (which
mpv used). Afterwards, it officially became public. Fortunately, the
lack of this field never actually made it into a release, so it could
have only possibly affected people building from the master branch.
Since ffmpeg 5.0 came out recently, and it's been plenty of months since
that two month window, we can go ahead and drop this check. This
finishes up the work done in 78cfeee2b9.
Sidenote: the cached ffmpeg version in the mingw ci were from that time
period when the bytes_read field was missing. The N in the workflow is
bumped to force a full rebuild and fresh clone of ffmpeg.
Both _NET_WM_NAME and _NET_WM_ICON_NAME (part of Extended Window Manager
Hints) require that the string is UTF-8*. mpv was not doing this and
thus violating the spec. Just sanitize the title for these two atoms.
Note that XA_WM_NAME and XA_WM_ICON_NAME have no such requirement so
those atoms are left the same. Fixes#8812.

Apparently mutter can send us 0x0 resizes* for whatever reason. Probably
there's some interal reason why this occurs, but for us trying to resize
to 0x0 is obviously terrible and results in all kinds of brokenness.

Previously, the sub-visibility option changed the visibility of all
subtitles including secondary ones. This meant that it was not possible
to only display secondary subtitles while hiding the primary ones. This
modifies the sub-visibility option so that it only affects primary
subtitles which allows only secondary subtitles to be displayed.
This reverts commit 04f0b0abe4.
It's not a good idea to unify the names only for visibility, while
keeping secondary-* for everything else.
This needs a bit more thought before we allow secondary sub to be
visible on its own.
Adds --sub-visibility choices 'primary-only' for only displaying the
primary subtitle track, and 'secondary-only' for only displaying
secondary subtitle track.
Removes --secondary-sub-visibility and displays a message telling the
user to use --sub-visibility=yes/primary-only instead.
These changes make it so that the default 'sub-visibility' bind 'v'
cycles through all the 'sub-visibility' choices, 'no', 'yes',
'primary-only', and 'secondary-only'.
Was tripping -Wparantheses as the && after the || was not explicitly

It currently defaults to false,

All of the run_command() calls currently use need to succeed for the

The AO provides a way for mpv to directly submit audio to the PipeWire
audio server.
Doing this directly instead of going through the various compatibility
layers provided by PipeWire has the following advantages:
* It reduces complexity of going through the compatibility layers
* It allows a richer integration between mpv and PipeWire
(for example for metadata)
* Some users report issues with the compatibility layers that to not
occur with the native AO
For now the AO is ordered after all the other relevant AOs, so it will
most probably not be picked up by default.
This is for the following reasons:
* Currently it is not possible to detect if the PipeWire daemon that mpv
connects to is actually driving the system audio.
(https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/1835)
* It gives the AO time to stabilize before it is used by everyone.

There was some breakage with regards to the iconv detection in some
older meson versions. This was all settled in 0.60.3 and now it simply
just works. Remove the workarounds and bump the needed meson version to
0.60.3.
When this was originally added, some OS package managers were slow and
behind the required meson version needed for mpv to build. Both opensuse
tumbleweed and freebsd now appear to carry meson 0.60.3 in their repos
so we no longer need to do the two-step process of installing pip3 and
then installing meson via pip. Instead, just use the OS package manager
version.
Useful to strip dolbyvision from the output, in cases where the user
does not want it applied. Doing this as a video filter gives users the
abiilty to easily toggle this stripping at runtime in a way that
properly propagates to any (potentially stateful) VO.
It also thematically fits the rest of the options in vf_format, which
are similarly concerned with modifying the video image parameters.
This needs to be forwarded from the AVStream to the AVPacket itself, so
that it reaches the decoder. There exists an FFmpeg function for this,
we just need to call it. (Also add some logging)
Instead of `xkb_keymap_new_from_string`. The protocol does not require
the keymap to be null terminated and if the size of the keymap is a
multiple of the page size, using `_from_string` could lead to problems.
Some compositors include a null byte and even include the null byte in
`size`. Therefore we have to use `strnlen` to find the real length of
the string. Note that `_from_string` internally uses `strlen` and then
calls `_from_buffer`.
While mpv uses version 1 of the `wl_seat` protocol and `MAP_PRIVATE` is
only required from version 7 on, using `MAP_PRIVATE` allows us to be
compatible with compositors that have only been tested with newer
applications.
Since the keymap is not modified after `mmap`, using `MAP_SHARED` has no
advantage over `MAP_PRIVATE`.
This merges the old desaturation control options into a single
enumeration, with the goal of both simplifying how these options work
and also making this list more extensible (including, notably, new
options only supported by vo_gpu_next).
For the hybrid option, I decided to port the (slightly tweaked) values
from libplacebo's pre-refactor defaults, rather than the old values we
had in mpv, to more visually match the look of the vo_gpu_next hybrid.
Merge --gamut-clipping and --gamut-warning into a single option,
--gamut-mapping-mode, better corresponding to the new vo_gpu_next APIs
and allowing us to easily extend this option as new modes are added in
the future.
image2D is only defined from GLSL ES 3.1 onwards, so those statements

fixes commit 584ab29c88
This commit is mainly for correcting the previous commit message.
The previous commit fixed an issue where [un]registering events above
the first event ID "hole" is not requested from libmpv, and that's
indeed true.
However, this had nearly zero impact in practice, because libmpv
enables all events by default anyway (except TICK).
Therefore, above the first ID "hole" [un]register requests are not
sent to libmpv, and the events just keep arriving.
But the callback functions are still added/removed correctly (at
defaults.js), and so the script is not called back even if unregister
did not actually happen with libmpv.
The only event which was affected is TICK - which is not enabled by
default as it's deprecated, and before the previous commit could not
be enabled.
So the fix is more a general correctness fix now that the IDs array
can have "holes", but with effctively no impact in practice.
Commit 63205981 removed some events but left all other event IDs at
their original values, which created "holes" at the events IDs array.
The JS backend for mp.register_event maps a name to an ID by scanning
all IDs and stopping when the name was found or a NULL name was
returned. Lua does the same except that it doesn't stop on NULL name.
Previously it was not possible to have a NULL name before the end of
the array, but now it is possible due to the enumeration holes.
Fix by skipping missing names, like lua does.
Back when the meson build was still in the PR state, this particular
variable was a dictionary. Later, it was refactored to simply be a
feature object instead. All uses of egl_drm['use'] should have been
replaced with egl_drm.allowed() but this particular line was missed
(that's what I get for not just doing find/replace). The conditional in
this line is usually satisified before egl_drm ever needs to be checked
which was why no one noticed until now. Fixes#9631.
Commits 04018c3061cd7a7a1de8 introduced behavior that
updated window geometry during wayland events (specifically surface and
output). This is good but they also are too aggressive with
automatically resizing. For example, if a window is manually resized by
the user and then dragged to a different monitor with different geometry
than the initial monitor, mpv will automatically resize itself to the
window's resolution. The initial thought behind this logic was for
autofit to automatically readjust itself on a new monitor, but doing
that breaks other common use cases. An attempt could be made to
distinguish between autofit and a manual resize but that introduces a
lot of complexity for an edge case. It's better to simply not change the
window geometry here. Internal values are recalculated and scaled of
course, but wl->window_size and wl->geometry should not change.
shaderc is a special case dependency in meson. According to the
documentation*, it first checks for shaderc_shared and will fallback to
shaderc_combined (the order is reversed if the static keyword is true).
However, shaderc also has a third .pc file (shaderc_static) which should
be checked. The meson documentation doesn't indicate this, but it also
actually checks shaderc_static*. shaderc_combined is first checked if
meson looks for static libs and if that is not found it tries
shaderc_static. So this extra fallback check is not needed.

Shaderc has been shipping .pc files for almost three years and we all
know of the advantages. If this turns out to be problematic the old checks
can be re-added but I'd like to avoid doing this preemptively.
During execve() ignored and blocked signals carry over to the child
process, though apparently for SIGCHLD (which the bug report was about)
this is implementation-defined.
fixes#9613
We've been assuming that maximum number of compute group threads is
never less than the 1024 defined by the desktop GL spec. Given that we
haven't had working compute shaders for GLES and I guess the Vulkan
spec defines at least as high a value, we've gotten away with it so
far.
But we should really look the value up and respect it.
This is only needed on Android and supposed to handle a context
resize without reconfiguring the image parameters. reconfig()
already does exactly this so plug it in there.
Not all deprecated symbols were removed. Only three events were removed for now
since these are not used internally.
This bumps the library version to 2.0.
Simply returning out of this function leaks avpkt, need to always "goto
done".
Rewrite the logic a bit to make it more clear what's going on (IMO).
Fixes#9593
It's supposed to work with GLES >= 3.1 but we had all sorts of bad
assumptions in our version handling, and then our compute shaders
turn out not to be GLSL-ES compliant.
This change contains some necessary, but insufficient, tweaks to the
shaders. Perhaps we'll make it actually work some day.
Some of the extension declarations did not include the ES version where
they became core functionality, and in some of these cases, there was
never actually an ES extension - it first appeared in core. We also had
a number of buggy version checks where ES versions were compared
against required desktop GL versions.
nvidia follow the OpenGL spec very strictly, with two particular
consequences:
* They will give you the exact context version that you ask for,
rather than the highest possible version that meets your request.
* They will hide extensions that the specs say require a higher
version than you request, even if it's technically possible to
provide the extension at lower versions.
In our case, we really want a variety of extensions, particularly
compute shaders that are only available in 4.2 or higher. That means
that we must explicitly include a high enough version in our list of
versions to check for us to be able to get a 'good' enough context.
As for which version? We restore the 4.4 version that we had in the
old version selection logic. This is the highest version we ever asked
for, and we have separate logic that clamps the GLSL version to 4.4,
so anything newer wouldn't make a difference.
Since libavcodec major version 59, the requested "ass" format became
the default as the old timing-included format was disabled starting
with that version. Additionally, this option by itself has since
been deprecated as it no longer serves any purpose.

This is a workaround for nvidia proprietary drivers. The authors of
those drivers interpret the spec such that eglMakeCurrent will not
reconfigure the read and draw buffers. Thus windows wont display
anything drawn by opengl. nvidia authors refer to
https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_no_config_context.txt
specifically Issues 2/3 which reference eglMakeCurrent.
On mesa this is a non-issue and the read/draw targets are assigned with
eglMakeCurrent.
The context must be made current in order to query OpenGL strings. An
earlier proposal to create the wayland window surface similarly to X11
during init was deemed inappropriate so instead we manually set the
targets once we have created a window surface.
Allow --keep-open=always to work with --loop-playlist, where
before this patch it would work only on the last playthrough of the

Fixes#9470.
Somewhat annoying but still relatively straightforward. There are
several ways to approach this, but I settled on reusing the pl_queue as
a cheap way to get access to the currently mapped frame. This saves us
from having to process `vo_frame` at all, and also avoids any overhead
from re-uploading the same frame twice.
(However maybe there's some circumstance in which `vo_frame` needs to be
queried/updated first, to get a screenshot of the correct frame? I'm not
sure.)
I also had the option of going with either pl_render_image() on the
extract pl_frame, or just calling pl_render_image_mix directly on it. I
went for the latter, because in the optimal case, this allows the
rendered frame to be directly retrieved from the cache, actually
entirely avoiding any sort of recompute overhead. This makes e.g. ctrl+s
during playback essentially free. (Except for the download cost,
obviously)
It would be even neater if we could make this VOCTRL asynchronous and
thereby leverage libplacebo's asynchronous download capabilities. But oh
well. That will have to wait for a sufficiently rainy day.
Closes#9388
20c4036daa switched to using symbol
visibility attributes for mpv client api functions (for the meson build
at least). Unfortunately mpv_client_api_version was mistakenly missed.
We need to export this function as well. Fixes#9531.
As noticed in #9526, apparently there's some case in which DR buffers
get corrupted. Add an explicit sentinel check to try and figure out
which cases these are.
The initial iconv dependency worked everywhere but was broken on
freebsd. This was fixed in 0.60.2 but the fix accidentally broke mingw
(ouch; kind of my fault for not double checking). There's another PR to
fix this but that won't land until 0.60.3 so for the meantime just
if/else this (both freebsd and windows work with the system method)
until we want to bump the meson version (probably not for a while since
opensuse tumbleweed is weirdly slow).
Previously OSD was always displayed on {ch,pl}_{next,prev} left-click,
and seekbar-hover-chapter was always enabled and with fixed format.
Now it can be controlled with:
- chapters_osd, playlist_osd: yes/no (only affects left-click).
- chapter_fmt: lua string.format template, or "no" to disable.
Fixes#4675
This commit sucks bad, but everything else is worse is other ways.
Basically, the current vblank waiting time in the vo_wayland_wait_frame
function (calculated very carefully using presentation statistics) is
randomly too short. Some compositors are quite variable when they
actually return callback so our timeout expires too quickly and throws
everything off. The fix? Add an arbitrary 5% to the vblank value and
pray that nothing gets off that much. Why did they have to make
swapinterval 1/fifo mode indefinitely block? Fixes#9504.
Better to avoid any wonky calculations on startup with garbage values.
The others end up being derived from last_ust/last_msc. refresh_interval
is referenced exactly once and could, in theory, result in some terribly
erroneous vblank time.
A read can be prepared on the wayland display FD that is never actually
read. This occurs when events are triggered on other FDs in the fd set.
This change cancels a prepared read if poll reported no events for it.
This fixes some hangs due to how nvidia's EGL implementation polls on
the wayland fd unlike mesa implementations. It is based on nvidia's
proposed fix for qt's similar message pump in

This is done to avoid cluttering vo_gpu_next.c with more ifdeffery and context-specific code
when additional backends are added in the near future.
Eventually gpu_ctx is intended to take the place of ra_ctx to further separate gpu and gpu_next.
This case was added in 662c793a55
for use in vo_gpu_next as a visibility test before rendering a frame.
The OpenGL context doesn't have this so it just returns true.
This is needed when the color system is not explicitly tagged, but
instead needs to be inferred by the VO.
Note that there exists the function mp_image_params_guess_csp for this
sort of stuff, but it contains a lot of baggage that I don't want to
replicate, in order to move as much of this logic into pl_renderer as
possible, and therefore also give it the best chance of knowing what
shortcuts it can and can't take.
Fixes the other half of https://github.com/mpv-player/mpv/issues/9499
Adding vsync_offset to the pts in pl_queue_update actually messes up
frame timings if one isn't using interpolation. The easiest way to see
this is to have the monitor's refresh rate at an integer multiple of a
video during a panning shot (classic case). There will be very visible
judder/stutter in this case that does not happen in vo_gpu. The cause of
this is the addition of the extra vsync_offset. Just match the semantics
of vo_gpu where this is only used when interpolating.
This possibility actually existed for years. The wayland protocol is
asynchronous and there's no restriction on when a compositor can send a
surface enter event. In mpv's case, the surface enter event is used to
set some vital things regarded geometry/scaling etc. However, this
implictly assumes that wl->current_output is actually initialized. The
vast majority of the time, vo_wayland_reconfig will happen first which
is where wl->current_output is, and should, be created. There's no
rule/law that the ordering of events will always occur in this order.
Plasma with certain auto-profile conditions can send the surface enter
event before mpv does its initial reconfig. That segfaults of course.
Just add a check to make sure we have wl->current_output here and return
if we don't. This assumes that the compositor will send us another
surface enterance event when mpv actually does the initial surface
commit and roundtrip request later. Wayland logs indicate this does
happen. Fixes#9492.
It was never implemented before but it's trivial. As an aside, touch
events currently don't support modifiers either (is this a thing?). Well
if someone complains that can be done later. Fixes#9490.
The audio rewrite in d27ad96542 originally
broke this ao. However, 0ac724f002 fixed
and the documentation was never updated to reflect that. OpenAL has
worked fine for a while not. Just remove this sentence.
Even when not display synced. Prevents redraw overhead for refreshes
while paused.
Also make the logic slightly clearer to follow (since it's inverted).
Following the previous commit, we can just set gnu_symbol_visibility to
'hidden' to hide everything except for the symbols we explictly want to
export. This should work on gcc, clang, and msvc.
In mpv, the only symbols we want to export are the functions from the
client API. This is accomplised using a specific .def whitelist, but the
main compilers people use (gcc or clang) like these attributes since it
allows for further optimizations. MSVC also allegedly supports this as
well (untested of course), so use __declspec for tht case.
This almost perfectly recreates the semantics of --vo=gpu, i.e.:
- still frames are never interpolated
- non-repeated frames bypass single frame cache
The only difference is that libplacebo doesn't do a cache/blit on the
full output image, but rather it re-runs the last rendering step. This
has some advantages and some drawbacks. The most notable advantage is
that it also allows re-using the image contents when the only thing that
changes is the OSD (whereas `--vo=gpu` would force a full re-render for
that). The most notable drawback is that it also implies going through
the dithering and output LUT logic on redraws. All in all, I think this
is a pretty good trade-off in favor of `--vo=gpu-next`.
Fully fixes the last remaining performance difference in #9430.
GLX_CONTEXT_PROFILE_MASK_ARB and related constants are provided by
GLX_ARB_create_context_profile but the check was for _create_context.
The former implies the latter (which we also need) so just replace
the checked extension.
It abstracts EGL 1.5, extension checks and other inconsistencies away.
This can be used in context code as the (preferred) alternative to
eglCreateWindowSurface().
Using a simple substring match for extension checks is considered bad practice
because it's incorrect when one extension is a prefix of another's name.
This will almost surely not make a difference in practice but do it for correctness anyway.
Although there are no known problems with this, using the helper should
be more portable. It will also prefer EGL 1.5's eglGetPlatformDisplay
over eglGetPlatformDisplayEXT if available.
The original implementation had some errors with regards to android. Add
a couple of missing files, add the android library, fix the aviocontext
bytes_read check, fix egl-android, and rearrange/tidy up the vulkan
handling.
While the basic Vulkan Display context can theoretically drive the
display without the involvement of any non-Vulkan code, that prevents
us from using VAAPI acceleration. When initialising VAAPI without a
window system, we need to provide it with an opened DRM render fd
corresponding to the device to use.
In the context of using VK_KHR_display, that means we need to identify
which DRM device matches the selected Vulkan device, and then open its
render fd and set the necessary state that VAAPI expects to find.
With that done, the normal VAAPI<->Vulkan interop can kick in and we
get working acceleration
A few custom targets had some less than optimal names which created some
misleading "Generating custom-target-name with a custom command"
messages. Change those to be more descriptive/correct. In a few other
places, some checks were being done that could easily be
skipped/ignored in certain cases (like checking for windows-related
headers when gl-win32 isn't true). Also rearrange that to be smarter.
Finally, print some extra libplacebo messages for enabling/disabling
vo_gpu_next.
This test fails because the compiler object does not have -Wformat when
it tries this flag. To fix this this, we have to pass both -Wformat and
-Werror=format-security at the same time during the test. This requires
us to use has_multi_arguments so this flag needs to be pulled out of
this array and tested separately.

Update the github workflows to also do meson builds for every OS.
Additionally, make every workflow execute the built mpv executable
(except for windows and FreeBSD's waf executable) to make sure that it
runs. As an aside, FreeBSD unfortunately is a bit less elegant since it
is in a VM.
The extension is completely arbitrary since ebml_defs.c isn't a real c
file that actually is compiled at any point in time. It's just used as
an include. The reason for changing the extension is because meson needs
to add this to its list of sources for dependency/ordering purposes.
Understandably, meson will try to compile any .c file added to a c
project executable object. Obviously, this compilation will never
succeed, and this shouldn't be compiled anyways. Just make it .inc
instead.
Another modification for the upcoming meson build. Meson can capture the
stdout and redirect it to a file. However, this is considered a hack.
It's better to just add a few lines to this script and write a file
directly.
Apple is great and forces us to do a lot of weird checks because they
randomly move the location of the swift libraries around. Make a
specific python script for checking various locations and write the
output to stdout for meson.
Building for macos requires us to check the macos sdk path as well as
the sdk version that is on the system. To do this, let's steal the logic
that's in the compiler_swift.py check from the waf build. This returns a
comma-delinated string. The first entry is the absolute path to the sdk.
The second entry is the detected macos sdk version.
version.h is essential for building, and its generation was done by a
shell script. Strictly speaking, python should in general be more
portable (windows), and would be better for the upcoming meson build to
simply just execute a python script. version.py has some small
differences with version.sh which shouldn't matter but they are noted
below.
- version.sh accepted several arguments that seemed useless (like
--cwd). These were removed from version.py.
- version.py takes either no arguments (prints the version) or it takes
exactly one argument specifying the complete path of where the header
should be generated.
- version.sh attempted to read a file named "snapshot_version". The
comments noted that this was for "daily tarball snapshots". Such a
file does not exist in the source tree, and it's not really clear that
anyone actually uses this. This logic was removed from version.py.
- version.py reads the SOURCE_DATE_EPOCH environment variable. Some
distros use this for reproducible builds. Technically you could also
just disable the build date but this is only a couple of extra lines
and maybe it's prettier than UNKNOWN.
- version.py also doesn't attempt to display timezone information in the
build date. It only shows UTC time.
d2e8bc4499 was the the commit that
originally introduced the usage of this bit. As the message states, the
purpose was to force creating GLES 3 contexts on drivers that do not
return a higher version context than what was requested. With the recent
opengl refactors, mpv's gl selection has already moved away from such
complicated queries. Perhaps when that commit was added things were
different, but nowadays it seems like Mesa simply returns the highest
driver version available that is compatibile with the request (i.e.
requesting GLES 2 returns a GLES 3 context on my machine). In that case,
let's just simply drop EGL_OPENGL_ES3_BIT altogether as it does break
GLES 2 only machines. Fixes#9431.
The new GBM supporting nvidia drivers declare support for 10bit
surfaces using BGR ordering, rather than RGB, so add support for them.
We've also seen examples of hardware supporting BGR8888 but not
RGB8888 so let's support those too.
Of course, the nvidia EGL driver doesn't publish support for any 10bit
formats so you can't actually do 10bit display. Perhaps they'll
eventually fix that.
The GBM supporting nvidia driver doesn't support creating surfaces
without modifiers and using modifiers is more and more recommended as
the right way to do this.
Enumerating modifiers is painfully verbose, but necessary if we are to
allow the driver to pick the best possible one.
This fixes a mismatch between configure working and build time
failing with Linux + OSSv4, enabling compilation on Debian based
Linux systems with the oss4-dev package.
Fixes#9378
This logic, which was working around a libplacebo bug, ended up always
alpha blending - even for sources without an alpha channel. This caused
a minor slowdown to be constantly enabled.
Due to the recent bump to libplacebo v170, this is no longer needed.
Completely untested, since Linux still can't into HDR in 2021. Somebody
please make sure it works.
Technically covers #8219, since gpu-context=drm can be combined with
vo=gpu-next.
This required an upstream API change to implement in a way that doesn't
unnecessarily re-push or upload frames that won't be used. I consider
this a big enough bug to justify bumping the minimum version for it.
Closes#9401
This was originally added in f2afae55e9
for unclear reasons (way to go me). This concept is clearly incorrect.
It doesn't matter what state the window is in. As soon as mpv detects a
scale change, it needs to reset the buffer scale of the window. Just
remove all this junk and put wl_surface_set_buffer_scale in
set_surface_scaling like it should be. Related issue: #9426.
Looking at this again I'm not sure it does anything useful at all. The
man page entry is also wrong: `bicubic` is not affected, only
`bicubic_fast`, and those filters are not configurable anyways.
So this would only ever be a debugging option, and I don't see a
pressing need for it.
No interface-change.rst update because it only just got added anyways.
In practice, this is for wayland. vo_gpu_next doesn't check the
check_visible parameter since it didn't descend into the
vulkan/context.c file when starting a frame. To make this happen, just
call the start_frame function pointer but pass NULL as the ra_fbo. In
there, we can do the visibility checks and after that bail out of the
start_frame function if ra_fbo is NULL.
This vulkan-specific parameter was poorly named and probably causes
confusion. Just rename it to check_visible instead to make clear what is
going on here. Only wayland uses it for now but in theory anyone else
can. As an aside, wayland egl accomplishes this by using an external
swapchain instead (an opengl-only concept in the mpv code). This may or
may not need to be changed in the future when gpu-next gets opengl
support.
As discussed in #8799, this will eventually replace vo_gpu. However, it
is not yet complete. Currently missing:
- OpenGL contexts
- hardware decoding
- blend-subtitles=video
- VOCTRL_SCREENSHOT
However, it's usable enough to cover most use cases, and as such is
enough to start getting in some crucial testing.
This seems to work on gcc, clang and mingw as-is, but I made it
conditional on __GNUC__ just in case, even though I can't figure out
which compilers we care about that don't export this define.
Also replace all instances of assert(0) in the code by MP_UNREACHABLE(),
which is a strict improvement.
A lot of people seem to do something like --tscale=box
--tscale-window=<function>. Just let them use --tscale=<function>
directly, by also accepting raw windows.
Kinda hacky but needed for feature parity with vo_gpu_next, which no
longer has `--tscale=box`. Note that because the option struct is still
shared, vo_gpu_next inherits the same option handling code, so we have
to export this feature for vo_gpu as well.
Back when runtime updating of autofit/geometry was added for wayland and
x11 (commits: 4445ac828dca0298543103094357e64f8828ef56 and
ced92ba607ebd98687b26ef3d8c09d5f6e22cf4b respectively), the naive
assumption was that window-related geometry would always be available.
While this is true 99% of the time, this isn't a guarentee. It is
possible for certain things such as loading shaders to delay starting up
the player. This causes autofit/geometry options to be registered as a
runtime update and triggers VOCTRL_VO_OPTS_CHANGED. This ends up calling
some geometry-related functions but this happens before the actual
values are available. Hence, a nullptr was accessed which segfaults. At
least one user experienced this with a combination of options in wayland
but in theory the same thing could happen under x11.
The fix is simple. Just be sure to check that the required geometry is
available before doing any calculations. In wayland, this would be
wl->current_output. Additionally add an assert to set_geometry (we
should never use this function without wl->current_output) to be extra
sure. In x11, the check is on x11->window. Later when the reconfig for
each backend actually happens, the autofit/geometry set by the user
happens anyway so ignoring it in this case does no harm. Fixes#9381.
The problem with the previous code - which used mp.get_user_path, is
that it returns a path even with --no-config, and even if the file
doesn't exist.
This is why we tested the "config" property, and also used
mp.utils.file_info to check that the file exists.
mp.find_config_file doesn't return a path with no-cofig and doesn't
return a path if the file doesn't exists. It's simpler and better.
Upstream libplacebo got refactored to use byte-sized strides rather than
texel-sized strides. This commit makes mpv's ra_pl wrapper take
advantage of that, rather than forcing a stride-fixing memcpy.
Note that, technically, we would still need a stride fixing memcpy in
cases when the true stride is not a multiple of the format's texel
*alignment*, however this is a much rarer case and extremely unlikely to
occur in practice, since all relevant formats use power-of-two texel
alignments.
In the reconfig event, the keepaspect option was checked before setting
the window_size geometry to the new params obtained from the vo. This is
incorrect. If a user disabled keepaspect on wayland, the video's size
would not change on a reconfigure event (i.e. loading a new video in the
playlist with a different size). No other windowing backend (x11, win32,
etc.) behaves like this or uses keepaspect in its code like wayland did
in this case. Clearly, this is not correct. Such functionality should be
handled by a separate option entirely. Just remove this if statement.
The bytes_read struct member in AVIOContext is now officially public,
so its usage no longer has to be specified as non-compliance with
FFmpeg's ABI/API rules.
That said, unfortunately there was a short period of time between
August 2021 and October 2021 where the struct member did not exist
in FFmpeg's git master, so keep a feature check for it alive for
now to enable building with those versions. Thankfully, no release
version of FFmpeg will be without this field, so it should be
possible to drop this check with time.
Finally, simplify the function in case the struct member is not
found. After all, there is zero reason to iterate through the AVIO
contexts if we cannot get the information we require.
Based on the idea behind emersion's change to drm_info
(https://github.com/ascent12/drm_info/commit/869e789a645b92a99e592a230fe39b0c59a2cd7d).
Lets us by default skip devices which are not capable of doing what
the DRM master output requires (not primary devices), as some devices
have card0 actually not be such.
Negative part is that the number given to drm-connector is no
longer a direct mapping against a file name.
Upon re-examination I have no idea why this code was ever written or
what problem it was trying to solve. But, getting rid of it fixes#9291.
It might be a remnant from before 2af2fa7a27. Who knows. This code will
be replaced soon(tm) anyways.
Regression from e13fe1299d. Apparently,
Broadcom's EGL does not support the EGL_CONTEXT_FLAGS_KHR attribute nor
EGL_CONTEXT_OPENGL_DEBUG_BIT_KHR. Just define these as EGL_NONE and 0

editorconfig configuration files hold editor style hints, and
is supported by many popular editors. See https://editorconfig.org/ .
The vast majority of the mpv source/text files are already styled as
4 space indentation, trailing newline at EOF, and UTF-8 encoding.
This commit adds a single .editorconfig root file which applies these
rules to all files using the glob "[*]".
If it turns out to be too inclusive then we can narrow it down later.

Normally there was no issue, but when the code converted a deeply
nested table into an mpv node - it didn't ensure the stack has room.
Lua doesn't check stack overflow when invoking lua_push* functions,
and leaves this responsibility to the (c) user via lua_checkstack.
Normally that's not an issue because when a lua (or autofree) function
is called, it's guaranteed at least LUA_MINSTACK (20) pushes.
However, pushnode and makenode are recursive, and each iteration can
add few values at the stack (which are popped when the recursion
unwinds), so checkstack must be used on (recursive) entry.
pushnode already checked the stack, makenode did not.
This commit checks the stack at makenode as well. The value of 6
(stack places to reserve) is with some room to spare, and in pratice
each iteration needs 2-3 at most (pushnode also leaves room).
Example which could previously corrupt the stack:
utils.format_json({d1={d2={<8 more times>}}}
This uses makenode to convert the lua table into an mpv node which
the json writer uses as input, and if the depth is 10 or more then
corruption could occur. mp.command_native is also affected, as well as
any other mp/utils command which takes a lua table as input.
While at it, fix the error string which pushnode used (luaL_checkstack
uses the provided string with "Stack overflow (%s)", so the user
message only needs to be additional info).
The speedup is due to moving big part of the autofree runtime overhead
(new lua c closure) to happen once on init at af_pushcclosure, instead
of on every call. This also allows supporting upvalues trivially, even
if mpv doesn't use it currently, and is more consistent with lua APIs.
While x2 infrastructure speedup is meaningful - and similar between
lua 5.1/5.2/jit, in practice it's a much smaller improvement because
the autofree overhead is typically small compared to the "real" work
(the actual functionality, and talloc+free which is needed anyway).
So with this commit, fast functions improve more in percentage.
E.g. utils.parse_json("0") is relatively fast and is now about 25%
faster, while a slower call like mp.command_native("ignore") is now
about 10% faster than before. If we had mp.noop() which does nothing
(but still "needs" alloc/free) - it would now be about 50% faster.
Overall, it's a mild performance improvements, the API is now more
consistent with lua, and without increasing code size or complexity.
mpv doesn't have other dot files in its config dir, and it also
shouldn't be "invisible".
The new name ~~/init.js now replaces ~~/.init.js
While mpv usually deprecates things before outright removing them,
in this case the old (dot) name is replaced without deprecation:
- It's a bad idea to execute hidden scripts, even if at a config dir,
and we don't want to do that for the next release cycle too.
- We warn if the old (dot) name exists and the new name doesn't,
which should be reasonably visible for affected users.
- It's likely niche enough to not cause too much pain.
If for some reason both names are needed, e.g. when using also an old
mpv versions, then the old name could be symlinked to the new one, or
simply have one line: `require("~~/init")` to load the new name, while
a new mpv version will load (only) the new name without warning.
With the recent refactor and quick look against the GLX code path, it's
fairly obvious, and trivial, how to add support for debug contexts.

Drop the gl3 suffix from the function name - it's no longer needed, with
the _old function gone.
Push the mpgl_min_required_gl_versions[] looping within the function,
reducing the identical glXGetProcAddress/glXQueryExtensionsString calls
while making the code neater.

The old/legacy code-path isn't really needed for mpv use-cases.
In particular:
All Mesa drivers (even GL 2.1 ones like lima/vc4) work fine with the
"non-legacy" path.
From proprietary/binary drivers - the vendor either does not support
desktop GL or the drivers/HW is not actively supported.
Looking at the Nvidia HW - anything GeForce 7 and older is GL 2.1 and
lacks decent video acceleration. The latest official drivers are from
2017.
All newer Nvidia HW is GL 3.3+ thus must have GLX_ARB_create_context as
in the non-legacy path, while also good acceleration albeit via VDPAU
in some cases.
With the old path gone, provide meaningful error message in the very
unlikely case that GLX_ARB_create_context is missing.

With earlier commit f8e62d3d82 ("egl_helpers: fix create_context
fallback behavior") we added a fallback for creating OpenGL context
while EGL_KHR_create_context is missing.
While it looked correct at first, it is missing the eglMakeCurrent()
call after creating the EGL context. Thus calling glGetString() fails.
Instead of doing that we can just remove some code - simply pass the
CLIENT_VERSION 2, as attributes which is honoured by EGL regardless of
the client API. This allows us to remove the special case and drop some
code.

The ra_gl_ctx_test_version() helper is quite clunky, in that it pushes a
simple check too deep into the call chain. As such it makes it hard to
reason, let alone have the GLX and EGL code paths symmetrical.
Introduce a simple helper ra_gl_ctx_get_glesmode() which returns the
current glesmode, so the platforms can clearly reason about should and
should not be executed.

As the documentation of the toggle says - the implementation can (and
will actually if they follow the GLX/EGL spec) return context version
greater than the one requested.
This happens with all Mesa drivers that I've tested as well as the
Nvidia binary drivers.
This toggle seems like a workaround for buggy drivers, yet it's lacking
context about the vendor and version.
Remove it for now - I'll be happy to reinstate it (partially or in full)
as we get concrete details.
This allows us to simplify ra_gl_ctx_test_version() making the whole
context creation business easier to follow by mere mortals.

Alike the GL commit earlier - the EGL spec essentially mandates that
implementation will return GLES 3.0+ (if supported by the driver), even
though only GLES 2 is requested.
The only thing we should watch out is - we should add both ES2_BIT and
ES3_BIT as EGL_RENDERABLE_TYPE.
This has been verified against the Mesa drivers (i965, iris, swrast) and
Nvidia binary drivers.

Currently mpv requires a bare minimum of GL 2.1, although it tries to
use 3.2+ core contexts when possible.
The GLX and EGL spec effectively guarantee that the implementation will
give you the highest compatible version possible. In other words:
Requesting 3.2 core profile will always give you core profile and the
version will be in the 3.2 .. 4.6 range - as supported by the drivers.
Similarly for 2.1 - implementation will give you either:
- 2.1 .. 3.1, or
- 3.2 .. 4.6 compat profile
This has been verified against the Mesa drivers (i965, iris, swrast) and
Nvidia binary drivers.
As such, drop the list to 320, 210 and terminating 0.

The ioctls were disabled a while back since they error out and allegedly
cause problem with X running in another VT.
Omitting the ioctls is not cool, even as a workaround.
If they fail, the user is supposed to fallback appropriately - use a suid
wrapper, logind-like daemon or otherwise.
As of kernel 5.10, they should just work in nearly all cases, so let's
just reinstate the calls.

This behavior is more convenient and allows profile conditions like:
[video]
profile-cond=get('current-tracks/video/image') == false
[image]
profile-cond=get('current-tracks/video/image')
Otherwise, these profiles have to be manually applied and restored in a
script.
The note about discouraging the use of current-tracks in scripts is
removed, because it makes people avoid using this convenient property.
It was added in 720bcd79d0 without leaving an explanation of why you
shouldn't use it, and the only reason seems to be that it doesn't work
with lavfi-complex, but this commit changes that.
This exposes whether a video track is detected as an image, which is
useful for profile conditions, property expansion and lavfi-complex.
The lavf demuxer sets image to true when the existing check detects an
image.
When the lavf demuxer fails, the mf one guesses if the file is an image
by its extension, so sh->image is set to true when the mf demuxer
succeds and there's only one file.
The mkv demuxer just sets image to true for any attached picture.
The timeline demuxer just copies the value of image from source to
destination. This sets image to true for attached pictures, standalone
images and images added with !new_stream in EDL playlists, but it is
imperfect since you could concatenate multiple images in an EDL playlist
(which should be done with the mf demuxer anyway). This is good enough
anyway since the comment of the modified function already says it is
"Imperfect and arbitrary".
This moves the image check to where the number of frames is available of
comparison, which allows not detecting jpg and png videos as images, and
detecting 1-frame gifs as images. This works with the mjpeg and png
videos in the FATE suite, though unfortunately the bmp video is still
detected as an image since it has nb_frames = 0.
aliaspix streams are also now considered images.
Attached pictures are now treated like standalone images, so audio with
attached pictures now has mf-fps as container-fps instead of
unavailable, which makes it consistent with external cover art, which
was already being assigned mf-fps.
Unfortunately images in a codec commonly used for videos are never
detected, and detection was inaccurate even using the now private
codec_info_nb_frames field in AVStream, and mediainfo gets them wrong
too, so I guess it's just a lost cause.
The custom init script should be considered a configuration file, and
as such it should be ignored when the user wants vanilla mpv - and now
it is ignored with --no-config.
This is similar to [no-]input-default-bindings, but affects only
builtin bindings (while input-default-bindings affects anything which
config files can override, like scripting mp.add_key_binding).
Arguably, this is what input-default-binding should have always done,
however, it does not.
The reason we add a new option rather than repurpose/modify the
existing option is that it behaves differently enough to raise
concerns that it will break some use cases for existing users:
- The new option is only applied once on startup, while
input-default-bindings can be modified effectively at runtime.
- They affects different sets of bindings, and it's possible that
the set of input-default-bindings is useful enough to keep.
Implementation-wise, both options are trivial, so keeping one or the
other or both doesn't affect code complexity.
It could be argued that it would be useful to make the new option
also effective for runtime changes, however, this opens a can of
worms of how the bindings are stored beyond the initial setup.
TL;DR: it's impossible to differentiate correctly at runtime between
builtin bindings, and those added with mp.add_key_bindings.
The gist is that technically mpv needs/uses two binding "classes":
- weak/builtin bindings - lower priority than config files.
- "user" bindings - config files and "forced" runtime bindings.
input-default-bindings affects the first class trivially, but
input-builtin-bindings would not be able split this class further
at runtime without meaningful changes to a lot of delicate code.
So a new option it is. It should be useful to some libmpv clients
(players) which want to disable mpv's builtin bindings without
breaking mp.add_key_bindings for scripts.
Fixes#8809
(again. the previous fix 8edfe70b only improved the docs, while
now we're actually making the requested behavior possible)
Currently using mpv --msg-level=help, shows an instance of --msglevel
(missing dash). Seems like the help message was only partially updated
with the -msglevel -> --msg-level transition.

Before this commit, animation-end was handled at render(), however,
it's not called on idle, which resulted in state.anitype ~= nil, with
nothing to reset it during idle, which caused in an infinite tick()
loop (starts on first mouse move).
Now tick resets the animation on idle, and also, as a safety measure,
if we're past 1s after the animation deadline.
The safety measure is because the osc states are complex, and it's
easier to detect a "we really shouldn't be animating now" at tick()
itself rather than detecting the exact states where animation should
be reset. Generally, the safety mmeasure is not needed.
TL;DR: use --lua=XXX for pkg-config name XXX, e.g. --lua=lua-5.1 .
For unversioned 'lua.pc', use the name luadef51/luadef52 .
Autodetection remains the same (5.2 names, luajit, 5.1 names).
The old names are still supported, but not auto-detected.
Before this patch, if one wanted to choose a specific lua version when
more than one is installed, then the names were a mess, e.g. 51obsd is
also the name detected on Arch linux, and other (distro) names are
also not unique to a specific distro/platform.
So to ask mpv to choose the package name (specifically, the pkg-config
file name), one needs to look at the mpv sources and find the
(arbitrary) distro name which has the same lua version naming as they
do on their own system, e.g. --lua=51obsd on Arch. This is a pain.
Now we add generic names:
- luadef51/luadef52 - generic pkg-config lua.pc (version is inside).
- lua* - exactly the pkg-config name, e.g. --lua=lua-51 for lua-51.pc
(the names are curated, e.g. --lua=foo won't detect foo.pc).
- The legacy names (e.g. 51deb) are still supported, but undocumented,
and the new generic names take precedence during auto-detection.
The fact that the generic names all start with "lua" has an additional
benefit that it shows right after "lua" at the output of mpv -v,
while the old names start with numbers, so they're first at the list,
making it hard to understand that e.g. "51obsd" is the lua version.
None of these names are actually used at the mpv code. The C code
checks the version using the lua headers (LUA_VERSION_NUM).
The lua version names which are autodetected/chosen (such as "51deb")
are used for two things:
- as key for storing the pkg-config compile/link flags.
- as ID for config.h and elsewhere - they're sanitized to use "_".
Due to some inconsistensies, if the sanitized ID is different than
the original name, then the compile/link flags are stored with the
original name as key, while the retrieval happens with the sanitized
ID - and therefore fails to find the correct flags.
The solution is to use the original name only for display purpose at
the output of configure, while using the sanitized version for
everything else, so that storage and retrieval use the same key.
Currently there's no issue and the patch has no effect, because the
sanitizer considers all the current names as valid IDs.
However, the next commit will add names which the sanitizer modifies,
such as "lua-5.1", so this commit makes such names work too.
Unfortunately, this functionality in large part based on a struct
member that was made private in FFmpeg/FFmpeg@7489f63281
in May. Unfortunately, this was not noticed during review.
This reverts commit 0862664ac9.
This CI builder bases on openSUSE Tumbleweed, and recently had
its glibc updated. This led to new syscalls such as 'clone3' not
being allowed through the security layer.
Can be reverted after Github Actions updates their security policy.

This exposes whether a video track is detected as an image. This is
useful for profile conditions, property expansion and lavfi-complex, and
is more accurate than any detection even Lua scripts can perform, since
they can't differentiate between images and videos without container-fps
and audio and with duration 1 (which is the duration set by the mf
demuxer with the default --mf-fps=1).
The lavf demuxer image check is moved to where the number of frames is
available for comparison, and is modified to check the number of frames
and duration instead of the video codec. This doesn't misdetect videos
in a codec commonly used for images (e.g. mjpeg) as images, and can
detect images in a codec commonly used for videos (e.g. 1-frame gifs).
pix files are also now detected as images, while before they weren't
since the condition was checking if the AVInputFormat name ends with
_pipe, and alias_pix doesn't.
Both nb_frames and codec_info_nb_frames are checked because nb_frames is
0 for some video codecs (hevc, av1, vc1, mpeg1video, vp9 if forcing
--demuxer=lavf), and codec_info_nb_frames is 1 for others (mpeg, mpeg4,
wmv3).
The duration is checked as well because for some uncommon codecs and
containers found in FFMpeg's FATE suite, libavformat returns nb_frames =
0 and codec_info_nb_frames = 1. For some of them it even returns
duration = 0, so they are blacklisted in order to never be considered
images.
The extra codecs that would have to be blacklisted without checking the
duration are AV_CODEC_ID_4XM, AV_CODEC_ID_BINKVIDEO,
AV_CODEC_ID_DSICINVIDEO, AV_CODEC_ID_ESCAPE130, AV_CODEC_ID_MMVIDEO,
AV_CODEC_ID_NUV, AV_CODEC_ID_RL2, AV_CODEC_ID_SMACKVIDEO and
AV_CODEC_ID_XAN_WC3, while the containers are film-cpk, ivf and ogg.
The lower limit for duration is 10 because that's the duration of
1-frame gifs.
Streams with codec_info_nb_frames 0 are not considered images because
vp9 and av1 have nb_frames = 0 and codec_info_nb_frames = 0, and we
can't rely on just the duration to detect them because they could be
livestreams without an initial duration, and actually even if we could
for these codecs libavformat returns huge negative durations like
-9223372036854775808.
Some more images in the FATE suite that are really frames cut from a
video in an uncommon codec and container, like cine/bayer_gbrg8.cine,
could be detected by allowing codec_info_nb_frames = 0, but then any
present and future video codec with nb_frames = 0 and
codec_info_nb_frames = 0 would need to be added to the blacklist. Some
even have duration > 10, so to detect these images the duration check
would have to be removed, and all the previously mentioned extra codecs
and containers would have to be added added to the blacklists, which
means that images that use them (if they exist anywhere) will never be
detected. These FATE images aren't detected as such by mediainfo either
anyway, nor can a Lua script reliably detect them as images since they
have container-fps and duration > 0 and != 1, and you probably will
never see files like them anywhere else.
For attached pictures the lavf demuxer always set image to true, which
is necessary because they have duration > 10. There is a minor change in
behavior for which audio with attached pictures now has mf-fps as
container-fps instead of unavailable, but this makes it consistent with
external cover art, which was already being assigned mf-fps.
When the lavf demuxer fails, the mf one guesses if the file is an image
by its extension, so sh->image is set to true when the mf demuxer
succeds and there's only one file.
Even if you add a video's file type to --mf-type and open it with the mf
protocol, only the first frame is used, so setting image to true is
still accurate.
When converting an image to the extensions listed in demux/demux_mf.c,
tga and pam files are currently the only ones detected by the mf demuxer
rather than lavf. Actually they are detected with the image2 format, but
it is blacklisted; see d0fee0ac33.
The mkv demuxer just sets image to true for any attached picture.
The timeline demuxer just copies the value of image from source to
destination. This sets image to true for attached pictures, standalone
images and images added with !new_stream in EDL playlists, but it is
imperfect since you could concatenate multiple images in an EDL playlist
(which should be done with the mf demuxer anyway). This is good enough
anyway since the comment of the modified function already says it is
"Imperfect and arbitrary".
Previously, loading ~~/.init.js was inside a try block, in order to
quietly ignore errors if the file doesn't exist.
However, that also prevented any real errors from showing up even when
the file does exist, and the script continued as if everything is OK,
while in fact the custom init script didn't complete correctly.
Now we first check if the file exists, and then load it without
try/catch, so that any error shows up normally (and abort the script).
The value of the border option should always match what the actual state
of the window is. Previously if a compositor rejected the request by
mpv, it did not correct itself. Also add some code to keep track of
decoration requests. Anytime the state is changed, make the last saved
request again (doesn't hurt and seems like intuitive behavior).
Unfortunately, this isn't foolproof since options only send callback if
the value is changed. (ex. on sway if the floating window has no border,
and then is titled, setting the border value to "yes" does nothing since
tiling the window already set the border value to "yes").
Fixes handle leak that happened whenever tvservice callback was invoked.
Powering on the TV causes HDMI unplug and attached events to be sent to
the tvservice callback.
This meant you could only power on/off your TV a finite number of times
before you were unable to allocate additional resources from VideoCore
(usually resulting in a "Could not get DISPMANX objects." error).
Furthermore because the VideoCore kernel driver does not cleanup handles
when a process dies, the only way to recover from the leak was to reboot
the RPI.
Because youtube-dl is inactive and the yt-dlp fork is becoming more
popular, make mpv use yt-dlp without any extra configuration.
yt-dlp is ordered before youtube-dl because it's more obscure, so users
who have yt-dlp installed are more likely to want to use it rather than
youtube-dl.

In Linux kernel commit 819fbd3d8ef36c09576c2a0ffea503f5c46e9177

been moved out again by Linus.)
We do not actually use this, and it's in a state of maybe-removal
from the kernel as of Linux 5.14. Get rid of it; mpv still builds
fine without it, so it wasn't needed anyways.

Without this, cases where the parser cannot return data right away
will end up utilizing the following fed packet's timestamps. This
will in turn cause an unnecessary offset in the audio stream
timestamps.
An example of such buffered parser in libavcodec is the EAC3 one.
Before this commit, timeBeginPeriod(1) was set once when mpv starts,
and the timers remained hi-res till mpv exits.
Now we do the same as before on Windows version < 10.
On Windows 10+ we now use timeBeginPeriod if needed, per timeout.
To force a mode regardless of Windows version, set env MPV_HRT:
- "always": the old behavior - hires timers as long as mpv runs.
- "perwait": sets 1ms timer resolution if timeout <= 50ms.
- "never": don't use timeBeginPeriod at all.
It was observed that on Windows 10 we lose about 0.5ms accuracy of
timeouts with "perwait" mode (acceptable), but otherwise it works
well for continuous timeouts (one after the other) and random ones.
On Windows 7 with "perwait": continous timeouts are accurate, but
random timeouts (after some time without timeouts) have bad
accuracy - roughly 16ms resolution instead of the requested 1ms.
Windows 8 was not tested, so to err on the side of caution, we keep
the legacy behavior "always" by default.
This brings enabled features on the same level as disabled and
auto-detected features by having both alternatives available.
Looking at the commit message of 652895abdc
this seems to have been the intent from the start, but this specific
definition was missing from the option creation in Features.
In wayland_common, wl->window_size keeps track of the window's size when
it is not in the fullscreen or maximized state. GET_UNFS_WINDOW_SIZE is
meant to report the size except for when it is fullscreen (hence UNFS).
However, the actual function was merely returning the wl->window_size so
it was wrong for maximized windows. Workaround this by returning
wl->geometry instead when we have the maximized case. Fixes#9207.
Its define (HAVE_FFMPEG_STRICT_ABI) is now utilized in a single
location, where an internal libavformat struct member is utilized.
This struct member is now (after around 10 years) finally removed
from public visibility in FFmpeg's master.
After a review of functionality, the information in bytes_read is
passed onto the demuxer layer, and then utilized for
{cache,hack}_unbuffered_read_bytes. This information is then utilized
for:
1. Calculation of bytes_per_second in demux/demux.c::update_cache,
which fills the information for properties "cache-speed" as well as
"raw-input-rate" (of which stats.lua is the most prominent user).
2. bytes_per_second also affects how often update_cache is called in
addition to the two locations it is called unconditionally in
(read_packet, demux_update).
In other words, the information provided does not appear to control
crucial mpv functionality, but rather its lack would seem to mostly
affect the speed of certain properties updating, or having valid
values. For the former, stream size as well as timed metadata get
updated in update_cache - although the demux layer does throttle
the update of certain things to once per second in that function.
For the latter, "cache-speed" and "raw-input-rate" lose read data
statistics from AVIOContexts opened by the opened FFmpeg AVFormatContext
itself, as opposed to the primary one - which goes through mpv's
stream reading implementation.
By enabling this feature, and disabling this abuse of private API
lets users build mpv by default with the latest master FFmpeg, thus
giving us the breathing room to look into some of the details of
this case, and either decide to:
1. Post a patch to add this information back to FFmpeg proper.
2. Remove or replace this functionality in another manner.
End user impact:
Any IO not handled by mpv itself - but rather by IO contexts newly
opened by the input format - is not visible through the properties
"cache-speed" and "raw-input-rate". Examples of such input formats
are the HLS and DASH readers in FFmpeg.

mpv https://youtube.com/watch?v=DBzFQgSMHdQ --ytdl-format=299
ytdl_hook.lua is unaffected by this because EDL lists don't go through
the file reader at demux_playlist.c (where each line was limited to
512K before this commit), however, EDL files on disk which are
loaded with --playlist=file.edl do.
Increase the limit to 2M so that such EDL files can also be loaded

Previously, the initial positioning and fit ignored the borders, and
centered the content (the video itself) at the working area.
Now, the initial positioning centers the window, by subtracting the
borders (if needed) from the target area for the initial fit/position.
While this does mean that the initial maximum content area is now
smaller than before, ultimately this has no impact on the window size,
because fit_on_screen is called later and, if needed, further shrinks
the window to fit the borders too - but without centering the window.
So the net impact of this commit is only the initial positioning (same
size as before), which now centers the window instead of the content.
Note that on Windows 10 the borders include invisible areas at the
sides and bottom of the window (for mouse edge-drag), so visibly the
window is nearer to the top than to the bottom, but these are the
metrics we have (fit_on_screen uses the same border size values).
On Windows 7 it looks perfectly centered.
The --monitoraspect value is calculated at vo_calc_window_geometry2
(VCWG2) or VCWG3, and applied via vo_apply_window_geometry.
Before this commit, the screen size which the win32 VO used with
VCWG2 was the working area (screen minus taskbar). This allows better
fitting, but breaks the pixelaspect calculation which is derived from
the --monitoraspect value and this rectangle.
VCWG3 allows an independent size for the aspect calculations, and now
we use it independently of the fit size.
vo_calc_window_geometry2 (VCWG2) calculates both the pixelaspect and
the autofit sizes based on one "screen" rectangle.
However, these two calculations might need two different "screen"
rects if the fit should take into account decorations and/or taskbar
etc, while pixelaspect should be based on the full (monitor) rect.
VCWG3 does just that. It's the same as VCWG2, but with an additional
monitor rect which is used exclussively to calculate pixelaspect,
while the "screen" argument is used for fitting (like before).
VCWG2 now uses/calls VCWG3 with the same screen and monitor rects.
Currently yet unused.
If bash_completion wasn't installed, _filedir wouldn't be defined which
led to all filename-based completions to error out. Specifically
autocompletion would fail when a filename was expected and when
bash_completion wasn't installed. Now we fall back to `compgen -f` if
_filedir fails. According to _filedir's comments, compgen doesn't
handle files with spaces well, but it is still better to complete most
files than none.
If an unknown ESC sequence is detected where an ASCII char <X> follows
the ESC, mpv interprets it as ALT+<X>, which is the traditional
terminal encoding of ALT+letter.
However, if <X> is '[' then it's a CSI sequence which continues after
the '[', and has its own termination rules (can be many chars).
Previously, mpv interpreted unknown CSI sequences as (incorrect) ALT+[
followed by (incorrect) "keys" from the rest of the sequence.
In this commit, if a unknown CSI sequence is detected, mpv ignores
exactly the complete sequence.
The "cycle" command _declaration_ enables repeatability by default,
however, the command handler applies additional logic to augment it,
based on the property which is being cycled - using some guesswork.
Specifically, properties with discrete values are not repeatable
(like sub or osd-level), while continuous properties are repeatable
(like volume).
Previously, the "repeatable" prefix could not override this additional
logic.
This commit changes the behavior so that the logic affects only the
default repeatability (still based on the property like before),
however, the "repeatable" prefix is now allowed to override it.
This is an artificial background box with the original colors,
rendered as a plain rectangle instead of libass's opaque-box.
Fixes#9134 (together with the previous commit)
This breaks the rendering in various ways, so first workaround is to
simply disable the opaque box for the bar.
Next commit will add an artificial background box.
This read-only property reflects the VO's dpi-scale value, and wasn't
supported on win32 until now (it is supported on wayland/x11/osx).
Currently in mpv it's only used by the builtin script console.lua,
and assumed 1 if unavailable.
When --window-scale=NUM is set from CLI, the dpi_scale value was/is
taken into account when the win32 VO calls vo_calc_window_geometry2.
However, when [current]-window-scale is read or set at runtime, it uses
the VOCTRL_{GET,SET}_UNFS_WINDOW_SIZE interface, where other VOs apply
the dpi_scale value internally (wayland, x11, osx), but the win32 VO
didn't before this commit.
Fixes two issues when --hidpi-window-scale=yes and dpi_scale != 1 :
- Incorrect window-size when setting [current-]window-scale at runtime.
- Incorrect current-window-scale value when reading it.
vo_calc_window_geometry2(...) is called to initialize the window
size with the dpi_scale value as one of the arguments.
dpi_scale is 0 initially, and set to a valid value at update_dpi(),
which is called from [force_]update_display_info().
However, no measures were taken to ensure that dpi_scale is set
correctly before vo_calc_window_geometry2() is called, which could
result in incorrect window size if it's not initialized.
It did happen to get initialized on time, by luck, because
VOCTRL_GET_DISPLAY_FPS is used early, which happens to call
update_display_info to read the fps value (other update_display_info()
calls are after the first vo_calc_window_geometry2() call).
This commit ensures that dpi_scale is initialized on time if needed.
Also, update_dpi() now ensures that dpi_scale is never 0.
Previously, a list of commands was always considered repeatable.
This behavior was added at 6710527a (and moved around since then),
in order to fix#807 (impossible to make a repeatable list).
The problem was that a list doesn't have the normal repeatability
flags and so it was never repeatable, so it was hardcoded to be
repeatable instead. Presumably it was deemed good enough.
However, this made it impossible to have a non-repeatable list.
This commit changes the behavior so that a list repeatability is
that of the first command at the list.
This way, any list can be made either repeatable or non-repeatable
using the following idiom (e.g. at input.conf), based on the fact
that the "ignore" command is not repeatable by default:
x ignore; cmd1...; cmd2... # non-repeatable
y repeatable ignore; cmd1...; cmd2... # repeatable
Fixes#7841

This is a regression from cbbd81bb (the previous commit):
print_seq1 (which prints a sequence with 1 parametric byte value) is
used with 256 colors output, and apparently was never tested.
Two issues were introduced at the offending commit:
1. The ";5" part was incorrectly removed from the strings
ESC_COLOR256_{BG,FG} (affects both *nix and Windows).
2. On windows only - a semicolon was not used after the prefix.
Both issues resulted in an invalid 256 colors sequences and output.
- Replace the legacy --osd-status-msg with the newer --osd-msg3.
- Escape \b in show-text "This is ${osd-ass-cc/0}{\b1}bold text".
- Link the Flat command syntax section because it's no longer true that
you always need to escape \, since C escape sequences are not
interpreted with single and custom quotes.
On windows the UTF-8 strings are translated to wchar_t when printed to
the console, and some escape sequences are also translated, however,
this only works when printf is mapped to mp_printf, and for that to
happen we need to include osdep/io.h .
Normally in wayland, you receive a keymap event from the compositor
which is what allows the client to setup what is needed for xkb.
However, it turns out that this doesn't occur in the case of virtual
keyboards, such as from wtype, that come from the custom
virtual-keyboard protocol. What happens in this case is that mpv only
receives a keyboard entrance event. According to the wayland protocol
documentation [1], "the compositor must send wl_keyboard.modifiers event
after [the wl_keyboard.enter] event". It is possible for this to occur
before the physical keyboard is properly mapped (i.e: using a virtual
keyboard to start mpv). What this results in is a segfault once
xkb_state_update_mask is called in the modifiers event. The fix is to
simply not always assume we have created the xkb state if we get this
event and check for its existence first. Closes#9119.

When changing video track with subtitles with unknown duration, they
aren't shown until you seek, cycle sub back and forth, or apply a video
filter. This is caused by reinit_video_chain_src() calling
reset_subtitle_state() -> sub/sd_ass.c:reset() -> ass_flush_events()
when ctx->duration_unknown is true.
The ass_flush_events() call was added in a714f8e so subs with unknown
duration wouldn't multiply on seek, i.e. when reset_subtitle_state() is
called from reset_playback_state(). So keep calling it from there, and
in reinit_video_chain_src() use just term_osd_set_subs(mpctx, NULL)
instead to clear any subtitles printed to the terminal. The
reset_subtitle_state() call was added in c1ac97b to "reset the state
correctly when switching between video/no-video", but with it removed I
no longer notice any issue doing that.
Previous fullscreen handling code was removed in 59cdfe50b2 during
deprecation of VOCTRL_FULLSCREEN. Lack of this code caused the OSD layer
to be to be not resized along with the video layer when fullscreen is
toggled.
If a user attempted to change the window scale of a maximized window on
x11, nothing would happen since the window manager holds the size of the
window constant. Just do an unmaximize first before performing the
resize.
When the VT switch out is triggered, the decode thread (VD) falls back
to sw decoding. However, on the VO thread, which is responsible for
handling display preemption and presentation, vo_vdpau.c:reconfig() is
called. The reconfig() function returned -1 when the check_preemption()
returned 0. The vo_reconfig2() (which calls reconfig()) returned -1 in
turn which entered into an error handling path. This led to a series of
functions calls that ultimately set the in_terminate flag to TRUE.
This led the vo_thread to exit which ultimately led to the
MPV application exit.
The fix is to return 0 instead of -1 after the check_preemption() in
the vo_vpdau.c:reconfig(). Returning 0 instead of -1 is not fatal and
does not have any side effects. This is confirmed by testing the VT
switching behaviour. And as far as the frames that are going to the
display are concerned, they are now dropped. Since the display is
preempted, it is okay to drop the frames and continue.
Without this entry, when starting mpv as a flatpak application on
elementaryOS, the Dock icon would get duplicated, as if the application
was detached from its launcher. This entry fixes that by allowing the
dock to associate the app's window with the desktop entry.
Fixes#9109
29e15e6248 prefixed youtube-dl's subs url with an edl prefix to not
download them until they're selected, which is useful when there are
many sub languages. But this prefix broke the alignment of secondary
subs, which would overlap the primary subs instead of always being
placed at the top. This can be tested with
--sub-file='edl://!no_clip;!delay_open,media_type=sub;secondary_sub.srt'
When a sub is added, sub.c:reinit_sub() is called. This calls in
init_subdec() -> dec_sub.c:sub_create() -> init_decoder() ->
sd_ass:init(). Then reinit_sub() calls
sub_control(track->d_sub, SD_CTRL_SET_TOP, &(bool){!!order}) which sets
sd_ass_priv.on_top = true for secondary subs.
But for EDL subs the real sub is initialized again when in
dec_sub.c:sub_read_packets() is_new_segment() returns true and
update_segment() is called, or when sub_get_bitmaps() calls
update_segment(). update_segment() then calls init_decoder(), which
calls sd_ass:init(), so sd_ass_priv is reinitialized, and its on_top
property is left false. This commit sets it to true again.
For URLs that need to be downloaded it seems that the update_segment()
call that reinitializes sd_ass_priv is always the one in
sub_read_packets(), but with local subs sub_get_bitmaps() is usually
called earlier (though there shouldn't be a reason to use the EDL URL
for local subs), so I added the order parameter to sub_create(), rather
than adding it to all of update_segment(), sub_read_packets() and
sub_get_bitmaps().
Also removes the cast to bool in the other sub_control call, since
sub/sd_ass.c:control already casts arg to bool when cmd is
SD_CTRL_SET_TOP.
Right after the listener is constructed, request a mode based on the
value of the border option. If border, then request SSD. If no border,
request CSD. The decoration listener handles it from there.
The previous wording gave the false impression that there was no media
key support for OSes besides Windows and macOS. This is untrue, the
option may only exist on those two platforms but it simply means that
media keys will always be enabled on other OSes as long as they are
supported.
The current usage of the xdg-decoration protocol is quite a bit crude.
There's a specific listener struct for this like with most wayland
things, but mpv wasn't even using it. It also made no attempt to detect
if the compositor was telling mpv to use client side decorations. To
implement this correctly, first of all we need to create the decoration
listener object and add it like how most wayland things work. Secondly,
set_border_decorations needs to be changed to accept the uint32_t mode
given by the compositor. When we get the decoration event, pass the mode
obtained from the compositor to set_border_decorations. Update the mpv
border option, based on whether or not we have server side decorations
(yes if we have them; no if we don't). mpv can actually request either
client side or server side decorations with this protocol. This function
doesn't belong in set_border_decorations but rather it should be called
when the border option changes. Whether or not this request actually
works depends on the compositor (Plasma appears to allow it; sway does
not). If the compositor allows this request, then it gets handled by
configure_decorations. Note that the enum strangely starts at 1 hence
why there is an extra +1.
When performing the scaling calculations, the window scale properties do
not bother checking for potential monitor par. The vo keeps track of
this via vo->monitor_par. Simply multiply/divide the video's width or
height depending on the value of monitor_par. We also clamp the values
to avoid the values running away to infinity in extreme cases.
The vo currently handles rotations in 90 degree steps and some VOs set
this via VO_CAP_ROTATE90. When the rotation exactly hits either 90 or
270 degrees, this causes the values of dwidth and dheight to perfectly
swap like one would expect. However, the mp_image_params_get_dsize
function call in both of the window scale functions do not take this
special case into account. So the width/height values returned will be
incorrectly flipped in the 90 and 270 degree cases if the vo driver does
implement VO_CAP_ROTATE90 (like vo=gpu). Fortunately, the
mp_image_params struct keeps track of the rotation for us. So all we
need to do is check if the image is rotated at 90 or 270 degrees and
check that the current vo driver supports VO_CAP_ROTATE90. If so, then
swap vid_w and vid_h to their true, correct values.
Based on a small patch originally written by @avih. Instead of
duplicating the window-scale logic in update_window_scale, just call the
mp_property_current_window_scale function with the M_PROPERTY_SET action
and a NULL property.
So the resizing mechanism is actually supposed to match the video size
to the window size while preserving the aspect ratio. In wayland, the
current logic behaves as if --no-keepaspect-window was set. Fix this by
simply multiplying the height by the same scale factor the width is
multiplied by. Also get rid of the pointless (width > height) test (it
makes no difference in any case) as well as some unneccesary checks for
the keepaspect-window option. The use of ceil here is to make sure the
window coordinates can never possibly have be 0 due to truncation
(weston can still give you a 1x1 window which is fun). Fixes#9098.
There's currently some touch related code in mpv wayland, but clearly
nobody actually uses because it's a broken mess. Initially an attempt to
distinguish between two finger touches and one finger touch was made,
but there's not a good way to make this work. For whatever reason,
initiating either xdg_toplevel_resize or xdg_toplevel_move blocks any
other touch events from occurring (at least in plasma). Trying to call
these functions anywhere else is not really useful since the serial will
be invalid outside of the touch down events (well it would work in the
touch up event but that's just silly).
Anyways, let's just make this work sanely. Eliminate the touch entries
variable completely because it's pointless. Only one finger event is
ever considered at a time. Touches besides the initial one are all
ignored. If a user touches and drags within the touch edge radius, then
a resize event occurs. If the user touches and drags elsewhere on the
window, a move event occurs. A single tap displays the osc (which is
clickable if you tap again). A double tap toggles fullscreen.
Additionally, the default touch edge radius of 64 pixels is way too big
(at least I think so). Cut this in half to 32 which feels a lot better
(on a pinephone using plasma mobile anyway).
The way the window-scale option is supposed to behave wasn't really ever
documented until 25cfc81. It turns out that different OS/WMs may do
slightly different things. For wayland, we need to fix two things.
First, only return the wl->window_size in GET_UNFS (aka don't return the
fullscreen size). For SET_UNFS, we need to change the behavior for the
maximized window case. If the window is maximized, first attempt to
unmaximize it and send the wayland event. If the compositor allows this
to happen, then go ahead and set the new dimensions and resize it. In
the case that the attempt to unmaximize is not successful, then don't
attempt the resize and just save the window size dimensions for later to
be used when the user unmaximizes the window.
The window-scale property mirrors the respective option (not the
effective scale derived from the current window size), and as such
setting its value to the same value it had before has no effect.
Specifically - the window will not resize.
This is consistent as far as property-option bridge behavior goes,
but we do end up with an issue that we can't set an arbitrary scale
and expect the window to always resize accordingly.
We do also have a current-window-scale property which does reflect
the actual window size, however, it's been read-only till now.
This commit makes current-window-scale RW so that it's now always
possible to set an arbitrary scale and expect the window to resize
accordingly (without affecting window-scale - like manual resize).
Also, mention window-scale no-effect-if-not-changed at the docs.
Based on code by @Dudemanguy from commit 873ae0d, with same effect.
This reverts commit 873ae0de2a.
The next commit will restore this functionality, with the
following differences from the reverted commit:
- Smaller and simpler code change.
- On bad scale: use "Invalid value" (compared to "no such property").
- Doesn't combine the docs for window-scale and current-window-scale.
- Doesn't remove the docs for window-scale behavior prior to 0.31.0.
Regression from 24357cb. It's ugly but unfortunately keeping tracking of
the last toplevel width and height really is the best way to solve this
problem and removing it was a mistake. Compositors don't always send
width/height coordinates of the actual window. The easiest way to
trigger this is by changing window-scale/current-window-scale and then
unfocusing the window. The compositor will send another toplevel
configure event with coordinates of the window before the resize. Maybe
compositors could be smarter but multiple ones do this (sway, gnome,
plasma), so just keep the old workaround. The only difference this time
is that the toplevel width/height is saved at the very beginning which
also covers the case where it equals 0 (i.e. weston).
Somewhat confusingly, mpv has both a window-scale option and a
current-window-scale property. The documentation lists window-scale
under properties (and it is technically is one), but at its core it is
actually an option which means it behaves subtly different. Options in
mpv are runtime-configurable, but they only change anything if the value
of the option itself changes. window-scale is an option and not meant to
keep track of the actual scale of the window (intended behavior
introduced by d07b7f0). This causes window-scale to do nothing in
certain cases (ex: the window is manually resized and window-scale is
set to 1.00 again). This is logical and consistent with the behavior of
the rest of the mpv options, but it also makes it a poor candidate for
setting the mpv window scale dynamically.
As a remedy, we can just make current-window-scale writeable instead.
current-window-scale is intended to always report the actual scale of
the window and keep track of any window size changes made by the user.
By making this property also writeable, it allows the user to have more
intuitive behavior (i.e. setting current-window-scale to 1.00 always
sets the window to a scale of 1). Additionally, the default input.conf
is changed to use current-window-scale instead of window-scale. The
window-scale documentation under property list is removed since it is
already documented under options and users should probably set the
current-window-scale property instead in most cases.
Using --sub-filter-regex-plain (default:no)
The ass-to-plaintext functionality already existed at sd_ass.c, but
it's internal and uses a private buffer type, so a trivial utility
wrapper was added with standard char*/bstr interface.
The plaintext can be multi-line, and the multi-line regexp flag is now
always set, but only affects plaintext (the ASS source is one line).
Pretty much identical to filter-regex but with JS expressions and
requires only JS support. Shares the filter-regex-* control options.
The target audience is Windows users - where filter-regex doesn't
work due to missing APIs, but mujs builds cleanly on Windows, and JS
is usually enabled in 3rd party Windows mpv builds.
Lua could have been used with similar effort, however, the JS regex
syntax is more extensive and also much more similar to POSIX.
1. On a pathological case where event_format is NULL, previously the
filter was trying to use it with each new sub - and re-failed. Now
the filter gets disabled on init (event_format doesn't change).
2. Previously, if the filter didn't modify the text or if the text
could not be extracted - it still allocated a new packet with same
content. Now it returns the original, saving a whole lot of no-ops
(there are still few allocations in this case though).
1 above is preparation for the next commit, and 2 was trivial, but
there's more to do if anyone cares (NIH string functions instead of
bstr, unused arguments, messages could be improved, and more).
Add two stand-alone function to help with the text-extraction task
which ass filters need. Makes it easier to add new filters without
cargo-culting this functionality.
Currently, on malformed event (which shouldn't happen), a warning is
printed when a filter tries to extract the text, so if few filters
are enabled, we'll get multiple warnings (like before) - not critical.
The regex filter now uses these utils, the SDH filter not yet.
The source of many geometry woes. There's some loosely related toplevel
things that should be cleaned up/fixed. First of all,
VO_EVENT_LIVE_RESIZING is actually completely useless. It might have
been useful sometime in the past, but there's no point. It doesn't
"speed up" resizing in any way and appears to be originally for cocoa.
Just remove it.
Way back in the day, toplevel_width/height was added as a workaround for
when we got uncoorperative (i.e. wrong) width/height coordinates from
the compositor in this event. Basically it could happen due to numerous
reasons but a lack of atomic commits was part of the reason and also
mpv's geometry handling then was a lot rougher. We *shouldn't* need this
workaround anymore. The width/height values are only used exactly when
we need them. If mpv sets geometry on its own, it should still be the
right dimensions.
Related to the above, mpv never actually propertly handled the case
where width or height was equal to 0. According to the xdg-shell spec,
"If the width or height arguments are zero, it means the client should
decided its own window dimension." An example of a compositor doing this
is weston. It's, unsurprisingly, broken. Getting out of fullscreen or a
maximized state does not restore the old window size like it should. The
right way to handle this is to just return near the end of the function
if we have a 0 for either argument and before any geometry is set
(wl->geometry's width or height can never be zero). Luckily, state
changes are already being detected so they just trigger the goto when
needed.
Finally, e2c24ad mistakenly removed the VO_EVENT_EXPOSE. There are edge
cases where this is needed and it's safer to just force a redraw here
when the window gets activated again. Just force wl->hidden to false
first and then trigger the expose.
Since 1d1d1fbff9 option-info/<name>/set-locally was being set to true
for every option. This broke setting start from ytdl-hook, which doesn't
overwrite start if it was set-locally. Fix this so that only adding an
option to reset-on-next-file or setting file-local-options/<name> make
set-locally true like before.
However, it's arguable that just adding an option to
reset-on-next-file without ever changing it should not make set-locally
true, so that e.g.
--reset-on-next-file=start 'https://youtube.com/watch?v=...&t=30'
will start at 30, though it currently doesn't.
Fixes#9081.
Previously we assumed the key-name string occupies strlen(name) cells,
now we count codepoints instead.
This improves alignment of non-english key names. Still not perfect
because we don't know if the key name is single or double width, but
wcwidth not available to scripts, notoriously unreliable (depends on
locale, correct and updated tables, etc), and also not always
available (Windows).
Still, better than nothing, and we err by at most one cell - vs up to
three before this commit (4 bytes keyname codepoint).
In the future we could do the alignment using libass tags, however,
this both complicates the ass-output generation, and also not available
when we output for the terminal, so for now only count codepoints.
Also, if the key name was in a right-to-left language, then previously
the name/command were swapped visually. Now we inject a left-to-right
marker before the name to ensure direction. This works also when
harfbuzz is disabled for libass (--sub-ass-shaper=simple).
Users expect single quotes to work when the value includes literal
backslashes or double-quotes (or as general quoting like in shell).
The updated docs also include some previously-missing notes:
- newline is only supported in double quotes.
- adjacent (quoted) arguments don't join into one.
Supporting mixed quoting (adjacent quoted strings) would make
mpv's parsing more complete, but would require delicate effort of
larger scope, for two reasons:
- We'd need to also support escaping outside of quotes and do our
best about backward compatibility.
- The parsed value can either be a substring of the input or
a newly-allocated string, which would be delicate when joining.
Not critical to add right now.
Custom quotes were added in 4f129a3e and began with !, however, this
required quoting "!reverse" (used for the cycle-values command), which
is inconvenient, and was not taken into account when ! was chosen for
custom quotes. Also, ` is more natural for quoting than !.
This does break backward compatibility with the earlier form of custom
quotes, but at least we didn't make a release yet since custom quotes
were added (the last release - 0.33[.1] doesn't support it).
Let audio-display determine whether embedded images or external cover

Because having these on every video is annoying, and when you resume
from watch later files, the filters are applied immediately so they hide
your osd-playing-msg or equivalent show-text commands.
More wayland weirdness. So previously, flipping a hidden state from true
to false was done in vo_wayland_wait_frame. In theory, this would be
after you get the frame callback and all those events so there's no
problem. However since the function also does a bunch of
flushing/dispatching/etc. to the default display queue so a lot of
unknown things can happen before we actually set the hidden variable
back to false. For example if a single image was paused and left on
another virtual desktop long enough (~5 minutes) while also not having
focus, switching back to that desktop could render it a black frame.
This edge case was supposed to be handled by the surface being activated
again in the toplevel event but apparently that doesn't always work. The
fix is to just delete all of that junk and set wl->hidden = false in the
frame callback. What's actually happening is kind of a mystery honestly.
Probably the compositor drops the buffers after a while as an
optimization (sensible) and forces a repaint if you switch back to the
virtual desktop. Somehow wl->hidden not being set to false would not
properly trigger a repaint (likely because it also sends a toplevel
event which does stuff) thus you just get a black window. If you just
make sure to set hidden in the frame callback, it appears like all of
these problems and edge cases are solved. Since this event must happen
first, that makes sense. That simplifies a lot of stuff and fixes some
subtle bugs at the same time so just go with this approach.
The EGL stuff is really complicated because of historical reasons
(tl;dr: blame EGL). There was one edge case with EGL context creation
that lead to incorrect behavior. EGL_KHR_create_context was created with
EGL 1.4 (which mpv does support) but it is still possible for an EGL 1.4
device to not implement this extension. That means that none of the EGL
attrs that pass a specific opengl version work. So for this obscure
case, there is a fallback context creation at the very end which simply
creates an EGLContext without passing any special attrs.
This has another problem however. mpv has a hard requirement on at least
desktop opengl 2.1 or opengl ES 2.0 to function (we're not asking for
much here). Since the fallback EGL context creation has no version
checking, it is entirely possible to create an EGL context with a
desktop opengl version under 2.1. As you get further along in the code,
the user will encounter the hard opengl version check and then error
out. However, we're supposed to also actually check if GLES works
(that's what the opengl-es=auto option is for) so this is a bug.
The fix is to do a bit of code duplication and make a mpgl_check_version
specifically for if we hit the edge case of needing to create an EGL
context without the EGL_KHR_create_context extension. Grab the version
with the function pointer, check if it's under 210, if so destroy the
EGL context and set it to NULL. After that, if the user has set
opengl-es to auto, mpv will try GLES next. If it is set to no, then mpv
will simply fail as desired. Fixes#5915.
Sidenote: the ra_gl_ctx_test_version originally testing 140 doesn't make
any sense. Passing the version number in that function only does
something if the user has set opengl-restrict. What we need to do is to
pass the version of the created context to that function. If the version
is higher than the opengl-restrict option, then make this a failure.
When changing image-display-duration at runtime, make the new value take
effect immediately, rather than from the next playlist-position change.
This allows toggling the slideshow mode while viewing images (without
hacks like executing playlist-play-index current afterwards).
All the conditions are just to be safe since even if you set time_frame
while playing a video, it's immediately overwritten by the next value.
mpv has two methods to display output from text input:
- show-text (scripting: mp.osd_message) has ass disabled by default
(escaped), and the property osd-ass-cc can control escaping.
- osd-overlay (scripting: mp.set_osd_ass or mp.create_osd_overlay)
has ass enabled (unescaped), and osd-ass-cc is NOT supported.
By default, stats.lua uses mp.osd_message which does support escaping.
That's persistent_overlay=no.
When using persistent_overlay=yes then mp.set_osd_ass is used.
Due to this, the no_ASS(..) function - which is supposed to escape
ass, simply returned its input unmodified when persistent_overlay
is enabled.
This is not a new issue, and the filters on page 1 use no_ASS() to no
avail in persistent mode, however, this content (filter name and value
strings) rarely actually needs escaping, and users didn't notice.
However, the new page 4 (keys) does break visibly when no_ASS doesn't
work, because it tries to escape arbitrary key-names and command
strings, and at the very least the key '{' is bound by default, which
is displayed incorrectly if escaping doesn't work.
Fix this by rolling our own escaping when using mp.set_osd_ass,
similar to how the mpv code does it for mp.osd_message (substrings
replacements).
However, this means that the set_ASS(..) function can no longer
behave correctly because escaping requires going through the whole
content string rather than only inserting a marker.
Luckily, other than at no_ASS, set_ASS was only used at one place
(text_style), which is only called from two places:
- generate_graph() only needs to restore styles - not to enable ass.
- add_header() is only used at the begining of page output, and
uses set_ASS to enable ass initially when using mp.osd_message.
So remove the set_ASS function, and instead enable ass directly at
print_page using osd-ass-cc when mp.osd_message is used.
Fixes#9022
This was explictly coded to avoid the autoprobe way back when in
2015[1] with no real explanation. In theory, there shouldn't be any
issues allowing this. If a user runs mpv in tty, this is probably what
they actually want in most cases. Perhaps something strange happens on
nvidia, but it should just fail anyway during the autoprobe.

As it turns out, js_try can throw if it runs out of try-stack
(without/before entering either the try part or the catch part).
If it happens, then C code which does allocation -> try will leak.
In mpv there were two places which do alloc and then try, one of
them as part of the autofree system. On both cases the leak is the
smallest possible (zero allocation) - talloc_new(NULL);
It's very unlikely to trigger - an autofree mpv API should be called
when the try-stack is exactly full, and our next try will throw
(and guaranteed to get caught at an outer level, but with a leak).
Fix that by doing the allocation inside the try block, so that if
try throws before it's entered then nothing got allocated/leaked.
Mujs internal code also has/had similar leaks, which are getting
fixed around this time (July 2021, post mujs 1.1.3).
[1] exhaust the try-stack or call-stack, whichever comes first:
function kaboom() { try { kaboom() } catch(e) {} }
--watch-later-options-remove doesn't accept multiple options, so split
the example.
Also suggest the more correct -clr to empty the list, and remove the
workaround to not print an error with --watch-later-options=
Previously, if a script bound the same key more than once to different
functions (without removing the older bindings first), then pressing
the key triggered any of the bound functions arbitrarily[1].
Now the newest binding for the same key is always the active one.
If the newest binding is then removed - the second-newest will become
active, etc. (same mechanism as before, except that the active key
was not always the newest).
[1] The order was implementation-defined, however `for (name in obj)'
happens to iterate. With mujs that's currently alhabetic order,
and name is from mp.add_[forced_]key_binding(key, name...)
or generated internally if name is not provided. So a binding with
higher alphabetic `name' value had priority over lower name value.
This allows configuring which options are saved by quit-watch-later.
Fixes#4126, #4641 and #5567.
Toggling a video or audio filter twice would treat the option as changed
because the backup value is NULL, and the current value of vf/af is a
list with one empty item, so obj_settings_list_equal had to be changed.
Unlike the page switching/scrolling keys which are bound at runtime
and therefore we need to know which (configured) keys to bind, the
main keys (i/I by default) are static and can be bound via input.conf.
And indeed, the builtin bindings at etc/input.conf have them already.
- The video filter to turn the video upside-down is vflip. There is no
filter called "flip" so using it just causes an error.
- Reword a sentence.
- Add exact and all to the values accepted by cover-art-auto. They were
implemented in 029ff1049b but not added to the accepted arguments.
Page 4 bindings listing wants to exclude the interactive keys of the
stats script itself - so that they don't hide the normal keys which
are bound when stats is not interactive.
It did so by testing that the bound command includes stats/__key
which is how it usually looks when a script binds keys.
However, if a script uses a name for the binding - like stats.lua does
for the interative keys (because it later removes them by name when
interactive mode ends), then the command has stats/name rather than
stats/__key...
To fix this, we change the names of the forced interactive bindings
to start with __forced_, and that's now also what the page-4 listing
excludes.
This reverts commit 0f1654811bda0dfdd337734ec33c59b67522234a.
It was an incorrect fix, because the key names do get used - to remove
the forced bindings once stats exits the interactive mode.
And without names - the interactive keys remained active even after
stats exited interactive mode.
The page 4 keybinding list tries to skip the interactive bindings of
stats itself (because they would hide the normal bindings of these
keys when stats is not visible), and to do that it excludes commands
containing "script-binding stats/__key" - which is how script-added
bindings usually look like.
However, keys which are added with a "name" bind stats/name rather
than stats/__key... - and that's what stats.lua did till now with its
interactive force-bindings.
Now the interactive forced bindings are added without a name, and so
they do end up using the automatic stats/__key... and get excluded.
While --input-test is useful, and so is page 4 of stats, until now
there was no way to simply print the list in a help-like fashion.
This commit adds such printout, invoked by the script opt
stats-bindlist=yes, which uses the existing page 4 code. This prints
the list on startup and quits immediately - like any help page.
It's awkward to invoke compared to other help pages, and it does
require the stats page to be enabled (it is by default), however
it is a script-generated output, and currently there's no other
method to print a help page generated by a script.
The printout itself is performed using lua's io.write. While reliable,
it's not the standard way for mpv to print to the terminal.
Other possible printout methods are mp.msg.info - which also prints
"[stats]" prefix on each line (ugly), or forcing term-osd and setting
an osd-message which mpv will then print at the terminal - however
that's printed to stderr, and could also be subject to timing concerns
since we quit right afterwards.
In the future we can consider changing/integrating the invocation so
that mpv itself could print a help page generated by a script, thus
solving both the awkward invocation and printout-method issues.
This is a scrollable page which also works nicely with the terminal
OSD. Typically there are more than 100 bound keys.
It groups the binding using fuzzy property/command/script name after
simple analysis of the command string, and then further sorts the
binding in each group according to the "complexity" of the key itself
(plain keys -> keys with modifiers, alphabetically, etc).
The alignment/grouping style is heavily inspired by @medhefgo's #8924
but otherwise it's an independent implementation.
Typically the current page is rebuilt and rendered once per second,
howeve, scrolling can invoke the rebuild function very frequently,
even at a rate which is too fast for the rebuild function to keep
up. This can result in high CPU usage and input lag.
This commit adds an argument to the page-rebuild function, letting it
know whether or not it's called following a scroll keypress, thus
allowing it to cache intermediate data so that it doesn't have to
re-calculate the whole page from scratch.
This additional argument is unused currently, but it could be useful
for the internal performance page - which can be relatively heavy.
When playing a new file, if paused_for_cache was true before being reset
the AO would never be unpaused because that state was thrown away, leaving it stuck.
Fix this by updating the pause state before resetting that variable. Note that this
does not make the second update_internal_pause_state() call redundant.
This fixes the same bug fb5d976cb0 was supposed to.
The previous code tried to disable autocrop for cover-art by testing
that track-list/$vid/albumart is false, however, $vid is completely
unrelated to the track-list index.
It only sometimes succeeded to disable for albumart, by accident,
e.g. with one audio track and one video track where $vid==1 and
track-list/1 happens to be the video (cover art) track.
The new code detects the currently-used video track by finding a track
with type=="video" and selected==true. Unlike the previous code, it
also works in scenarios with many audio/video/sub tracks.
Additionally, autocrop is now enabled also with lavfi-complex, which
should be considered an improvement. The previous code implicitly
disabled it with lavfi-complex because $vid is nil on such case.
in->byte_level_seeks field is written and modified inside
update_bytes_read at the same time when demux_get_reader_state
is executing, which locks the demux thread mutex. This results
in a data race, reported by Thread Sanitizer when playing mp3 file
of sufficient long length.
reinit_audio_filters_and_output function will free mpctx->ao_chain
when there is a failure during audio initialization. So modify it
to return -1 in case of init failure. The return value is checked
to avoid use after free. Reported by Address Sanitizer when manually
specifying --ao which triggers "Failed to initialize audio driver" error.
When using "stty susp ''" to disable sending the TSTP signal with ^Z,
mpv didn't recognize ^Z correctly in the terminal:
[input] No key binding found for key 'Ctrl+2'.
Because ASCII 26 (^Z) and above were incorrectly considered ^<NUMBER>.
This commit moves the cutoff between letters/numbers from 25 to 26 so
that ^Z is now detected correctly as ^<LETTER>.
Additionally, it rephrases the ^<NUMBER> formula for clarity.
The --secondary-sub-visibility options was previously undocumented in
the pull request that added it. This commit adds documentation for it
and clarifies its behavior.
Modifies the sub-seek and sub-step commands with a second <flags>
argument to specify whether to seek/step on the primary or secondary
subtitles. The flag is used to index into the current_track array in
cmd_sub_step_seek.
Adds secondary-sub-start and secondary-sub-end properties by setting
the current_track index in the m_property's priv variable which later
gets accessed in get_times. Also adds a test of the secondary subtitle
time properties in tests/subtimes.js bound to 'T'.
Though, only when the output format is matroska, to avoid muxing errors.
This is quite useful when the input has ASS subtitles, as they tend to
rely on embedded fonts.
I've looked and studied the flow in the recorder, and to my
understanding, the packet queue is moot after the initial sync, maybe
even then - but that's beyond me right now.
With the previous choice to mux trailing packets whatever the case, this
doesn't result in any new ill effects (and some missing packets at the
end is no big deal).
Notably, since we don't have to hold onto the packets after we get
muxing, we'll never run into any issues with veeery long GOPs filling up
our queue (resulting in dropped packets and much user chagrin).
For muxing, FFmpeg expects the FLAC extradata to be just the bare STREAMINFO,
and passing the full FLAC extradata (fLaC header and block size, with any
additional channel layout metadata) will result in malformed output, as
ffmpeg will simply prefix another fLaC header in front.
This can be considered to be a bug.
FFmpeg's own demuxers only store the STREAMINFO, hence the naivety, while
our common source of FLAC streams, the matroska demuxer, holds onto the
full extradata. It has been deemed preferable to adjust the extradata upon
muxing, instead of in the demuxer (ffmpeg's FLAC decoder knows to read
the full fLaC extradata).
This fixes muxing FLAC streams, meaning recorder.c or dump-cache.
dump_cache() calls qsort() to order an array of pointers, while the
comparator forgets it's receiving pointers to pointers.
Since cache-dumping over multiple cache ranges is fairly rare, this
seems to have gone unnoticed.
In commit f7678575a5, wm4 chooses to mux
all remaining packets when mp_recorder_mark_discontinuity() is called and
adds a call to mux_packets(). However, it is called only after flush_packets(),
which clears the packets before they can be muxed out. This has no ill
effects per se - recordings end on keyframes, as before - but judging from
his commit message, the intention explicitly was to output the inter
frames, since long GOPs can mean several seconds of missing content from
the output. So, clear the stream packet queues only after the final mux.
Also, flushing can mean both discarding and committing. What a country!
osc-visibility can already be changed at runtime via script-message
or other means, but until now there was no way to tell what the
current state is.
Now shared-script-properties/osc-visibility reflects this state.
It's output-only by the osc - changing it does not affect the osc.
Useful if a script wants to change osc-visibility temporarily, and
later restore to its original state.
There's no way to coordinate if more than one script wants to change
it, but that would be a hard problem to solve anyway, even if the
osc itself tried to coordinate such requests from different sources.
Another day, another wayland refactor. Way back when, dcc3c2e added
support for the hidpi-window-scale option (something you probably should
never set to no but whatever) to wayland. Well technically, it never had
any runtime toggling support (don't remember if detecting when vo_opts
changed was possible or not then; maybe not). Anyways in the process of
fixing that, I went ahead and refactored how this is all handled. The
key difference is that when hidpi-window-scale is disabled, wl->scaling
is directly set to 1 instead of forcibly setting
wl->current_output->scale to 1. Note that scaling operations don't
always require a geometry reset/resize so set_surface_scaling needs to
be separate from set_geometry. The logic here is kind of complicated but
it (should) be correct.
The wl_surface lives for the entire lifetime of the vo. It's only
neccesary to set the scale initially and when the output scaling changes
(the surface moves to a different output with a different scale or the
output itself changes it scale). All of the calls that were being made
in the egl/vulkan resize functions are not needed. vo_wlshm wasn't
correctly rescaling itself before this commit since it had no logic to
handle scale changes. This should all be shared, common code in the
surface/output listeners.
A subtle regression from c26d833. On sway if mpv was set to be a
floating window in the config, set_buffer_scale would actually get
applied twice according to the wayland log. That meant a 1920x1080
window would appear as a 960x540 window if the scale of the wl_output
was set to 2. This only affected egl on sway (didn't occur on weston and
was too lazy to try anything else; probably they were fine). Since
wl->render is initially false, that meant that the very first run
through the render loop returns false. This probably caused something
weird to happen with the set_buffer_scale calls (the egl window gets
created and everything but mpv doesn't write to it just yet) which makes
the set_buffer_scale call happen an extra time. Since it was always
intended for mpv to initally render, this is worth fixing. Just chnage
wl->render to wl->hidden (again) and flip the bools around. That way,
the initial false value results in render == true and mpv tries to draw
on the first pass. This fixes the weird scaling behavior because
reasons.
Not sure what I was on when I wrote this. wayland-app-id is supposed to
default to "mpv". Just set that in the vo_sub_opts and don't do this
weird m_config_cache_write_opt thing. Also make the doc entry nicer.
Mostly a cosmetic change that (hopefully) makes things look better. Some
functions and structs that were previously being exported in the wayland
header were made static to the wayland_common.c file (these shouldn't be
accessed by anyone else).
When the current file is hidden and `ignore_hidden` is true,
autoload will skip loading other files in the current directory. Make
sure that the current file is always counted for autoloading even if it
is hidden.
In 8a7614a0fb files that start with a '.'
were blacklisted from autoload.lua. Since then
35e8710b86 was introduced and explicitly
whitelisted file extensions. With this change, there is no longer a
reason to blacklist all files starting with '.', because it is valid to
have a file called '.hidden.mkv', and there is no chance of hidden files
such as '.bashrc', '.DS_STORE', '.gitignore', etc. being autoloaded by
mpv.
This commit tries to keep the same behavior as before, which is to by
default not load hidden files, but allows the user to optionally allow
hidden files to be autoloaded.
Commits 4d1ffec and 6e481d0 renamed sub-ass-style-override to
sub-ass-override. But in commit bd603c2, when renaming it in
quit-watch-later's backup_properties, which determines which properties
are saved by quit-watch-later/write-watch-later-config, it was
incorrectly renamed to sub-style-override instead, and thus never got
saved even if modified at runtime. Instead mpv attempted to save the
non-existing property "sub-style-override", but since no error is raised
when saving non-existing properties with quit-watch-later, no one
noticed it. This commit renames the saved property to the correct new
name "sub-ass-override" so that it does get saved.
This fixes two issues, both of which resulted from the timers-wait
period not being re-calculated after idle-observers were executed:
- If timers were added from an idle observer then they could fire long
after they were due (only when/if the next mpv event arrives).
- Idle observers don't execute in zero time, and the wait period for
the next timer was implicitly extended by the idle observers
execution time (because it was calculated before the idle observers).
This commit ensures that if idle-observers were executed, then the
timers wait period is re-calculated, which solves both issues.
Previously, process_timers() kept going as long as there were due
timers, which could be for extended periods of time or even forever
if there were slow timer callbacks with either periodic timers or if
timers were added repeatedly.
This prevented dequeuing mpv events, and subsequently, among others,
prevented mpv from quitting until process_timers() completed.
For instance, this caused process_timers() to never return:
function render() <longer than 1/60 s on a slow system> end
mp.add_periodic_timer(1/60, render)
Similarly, it never returned if a timer callback always added a new
one-shot which was already due by the time the callback completed.
This commit ensures that process_timers() only executes callbacks which
were due when it started, so that timers which are added (or repeated)
during process_timers() will wait for the next iteration - after mpv
events are dequeued.
This has no performance impact under normal conditions (when callbacks
complete before the next timer is due).
Additionally, previously idle-observers were executed unconditionally
after the timers because indeed there was nothing due when (if...)
process_timers() completed. However, now process_timers() can return
even if there are due timers, so skip idle-observers on such case.
This fixes a long-standing apparent issue where mpv would display the last
frame with no subtitles at EOF. This is caused by sub rendering switching from
video timestamps to audio timestamps when the video ends, and audio streams
often running past the timestamp of the last video frame. However, authoring
tools (most notably Aegisub) don't tend to provide easy ways to add meaningful
subtitles after the end of the video, so this is rarely actually useful.
This makes cover-art-auto behave more like sub-auto and audio-file-auto:
- load cover art with a language, e.g. if playing foo.mp3, foo.en.jpg
will be loaded with lang=en
- load cover art containing the media filename with fuzzy and all, e.g.
'foo (large).jpg'
- make all/2 load all images in the directory, and make fuzzy/1 the
default
These are all uncommon use cases, but synchronizing the behavior of the
external file options simplifies the code.
The idle-observers block has at least 3 function calls, and it was
entered every time the script went into idle, however, we can save these
calls by checking first that there are indeed such observers.
Remove the check that the external filename is not the same as the
currently playing one, which prevents mpv from loading images again as
external cover art, but this isn't necessary because cover art is only
added when playing standalone audio. I had only added this check because
I would otherwise get a segfault only when compiling with gcc 10.2 with
optimize and changing position within a playlist of multiple images (and
this couldn't even be reproduced by Dudemanguy on the same gcc version),
but this was caused by the uninitialized lang variable which is now
fixed.
Commit 029ff10 added a goto statement which skipped initializing the
`lang' variable. This could crash depending on compiler optimizations
and other factors: if the lang bstr pointer happened to end up NULL
(which is apparently the case with most compilers) then it's validly
empty, but if it pointed to a random and incorrect memory address then
it crashed.
The crash was observed when mpv was compiled using gcc 10.2 with
optimizations enabled, and affected some third party Windows builds.
This commit ensures the goto doesn't skip the initialization.
Thanks to votemp for figuring this out.
Fixes#8922.
Previously tick() was ensured unconditionally only after mouse-move,
but there are other mouse-events which need re-rendering (tick), like
mouse-down (icons may get grayed-out) or mouse-up (icons may change).
For instance: mpv --pause --myclip.mkv
then move the mouse over the volume/mute OSC button, then - without
moving the mouse - press and release the left mouse button.
The osc was not re-rendered because it's paused and the mouse didn't
move, so the volume icon didn't get grayed-out when held down, and the
icon doesn't change on mouse-up (to reflect the new mute state).
Now both these changes are rendered correctly.
This is not a new issue, however, until the last commit - 96b246d
init probably didn't happen much (or at all) between mouse-down and
mouse-up, but after this commit, if there are chapters in a live-stream
then osc_init() is used to re-render the markers at the adjusted
position - which breaks the OSC buttons functionality if init happened
between mouse-down and mouse-up.
Commit 6abb7e3 updates the markers when the chapters change, but it
doesn't update their relative position at the bar when the duration
changes.
This means that adding chapters to a live stream would result in
corresponding chapter markers which were static while the duration
changed and thus their positions became incorrect over time until the
OSC was reinitialized.
This is fixed by observing the duration property if chapters are present
and reinitializing the OSC when the duration changes.
The live_markers user option, which determines whether the duration
property is observed when there are chapters, has been added in order to
allow disabling this behaviour as calling request_init() frequently
might have some impact on low-end systems.
The impact of request_init() on render() was measured to increase from
1-1.5 ms to 2-3 ms on a 2010 MacBook Air, while the impact was neglible
on a 2016 Surface Book (increasing only to an average of 1.4 ms from
1.3 ms for n=1500 render cycles).
The live_markers option is enabled by default.
If a plane is not connected to any displays, we won't set an entry in

Fixes#8913
This is the Vulkan equivalent of the drm context for OpenGL, with
the big difference that it's implemented purely in terms of Vulkan
calls and doesn't actually require drm or kms.
The basic idea is to identify a display, mode, and plane on a device,
and then create a display backed surface for the swapchain. In theory,
past that point, everything is the same, and this is in fact the case
on Intel hardware. I can get a video playing on a vt.
On nvidia, naturally, things don't work that way. Instead, nvidia only
implemented the extension for scenarios where a VR application is
stealing a display from a running window system, and not for
standalone scenarios. With additional code, I've got this scenario to
work but that's a separate incremental change.
Other people have tested on AMD, and report roughly the same behaviour
as on Intel.
Note, that in this change, the VT will not be correctly restored after
qutting. The only way to restore the VT is to introduce some drm
specific code which I will illustrate in a separate change.
The VkDisplayKHR context type requires making calls against the
physical device before the libplacebo context is initialised.
That means we can't simply use the physical device object that
libplacebo would create - instead we have to create a separate one,
but make sure it's referring to the same physical device.
To that end, we need the device name that the user may have requested
so we can pass it on.
This moves the JSON parsing above the main youtube-dl error-handling
block and integrates parsing errors into that block. Now, if a parsing
error occurs, youtube-dl's stderr will be logged as it is with other
errors. This also catches errors that cause youtube-dl to output
"null", which would previously be mishandled as a parsing error and
crash ytdl_hook when it attempted to concatenate the error string from
parse_json.
This was originally just a bugfix for a race condition, but the scope
expanded a bit. Currently, the wayland code does a prepare_read ->
dispatch_pending -> display_flush -> read_events -> dispatch_pending
routine that's basically straight from the wayland client API
documentation. This essentially just queues up all the wayland events
mpv has and dispatches them to the compositor. We do this for blocking
purposes on every frame we render. A very similar thing is done for
wait_events from the VO.
This code can pretty easily be unified and split off into a separate
function, vo_wayland_dispatch_events. vo_wayland_wait_frame will call
this function in a while loop (which will break either on timeout or if
we receive frame callback from the compositor). wait_events needs to
just check this in case we get some state change on the wakeup_pipe
(i.e. waking up from the paused state).
As for the actual bugfix part of this, it's a slight regression from
c26d833. The toplevel config event always forced a redraw when a surface
became activated again. This is for something like displaying cover art
on a music file. If the window was originally out of view and then later
brought back into focus, no picture would be rendered (i.e. the window
is just black). That's because something like cover art is just 1 frame
and the VO stops doing any other additional rendering. If you miss that
1 frame, nothing would show up ever again. The fix in this case is to
always just force a redraw when the mpv window comes back into view.
Well with the aforementioned commit, we stopped doing
wl_display_roundtrip calls on every frame. That means we no longer do
roundtrip blocking calls. We just be sure to queue up all of the events
we have and then dispatch them. Because wayland is fundamentally an
asynchronous protocol, there's no guarantee what order these events
would be processed in. This meant that on occasion, a
vo_wayland_wait_frame call (this could occur multiple times depending on
the exact situation) would occur before the compositor would send back
frame callback. That would result in the aforementioned bug of having
just a black window. The fix, in this case, is to just do a
vo_wayland_wait_frame call directly before we force the VO to do a
redraw. Note that merely dispatching events isn't enough because we
specifically need to wait for the compositor to give us frame callback
before doing a new render.
P.S. fix a typo too.
And also change the existing WM_KILLFOCUS handler to return 0 instead
of 'break' (which later calls DefWindowProcW), as MSDN says we should
do for WM_{KILL,SET}FOCUS.
It seems that the 'focused' property is now supported by all main VOs:
x11, macOS, wayland, Windows.
TCT/sixel/caca probably don't support it, and unknown with SDL.
Fixes#8868
When the OSC initializes, it checks whether the current video has
chapters, and if it does not, it disables its chapter functionality
(chapter buttons are grayed out and unusable, chapter indicators don't
show on the seek bar). If another script changed the chapter list
after the video has loaded, those changes would be ignored by the OSC
until some other event causes it to re-initialize, because it did not
observe the chapter list property. This is fixed by adding
observation of chapter-list alongside the other properties that
trigger re-initialization.
Avoiding blindly copying the codec_tag between different formats allows
us to mux packets from, say, mpegts streams to matroska, making the
recorder (dump-cache) much more usable as unsupported codec_tags can
make the muxer reject the streams.

Not only does this have semantics that make far more sense, it also has

This removes the weird 1000:1 contrast default assumption which

Should probably close some issues but I honestly can't be bothered to
figure out which of the thousands colorimetry-related issues are
affected.
Take two. f4e89dd went wrong by moving vo_wayland_wait_frame before
start_frame was called. Whether or not this matters depends on the
compositor, but some weird things can happen. Basically, it's a
scheduling issue. vo_wayland_wait_frame queues all events and sends them
to the server to process (with no blocking if presentation time is
available). If mpv changes state while rendering (and this function is
called before every frame is drawn), then that event also gets
dispatched and sent to the compositor. This, in some cases, can cause
some funny behavior because the next frame gets attached to the surface
while the old buffer is getting released. It's safer to call this
function after the swap already happens and well before mpv calls its
next draw. There's no weird scheduling of events, and the compositor log
is more normal.
The second part of this is to fix some stuttering issues. This is mostly
just conjecture, but probably what was happening was this thing called
"composition". The easiest way to see this is to play a video on the
default audio sync mode (probably easiest to see on a typical 23.976
video). Have that in a window and float it over firefox (floating
windows are bloat on a tiling wm anyway). Then in firefox, do some short
bursts of smooth scrolling (likely uses egl). Some stutter in video
rendering could be observed, particularly in panning shots.
Compositors are supposed to prevent tearing so what likely was happening
was that the compositor was simply holding the buffer a wee bit longer
to make sure it happened in sync with the smooth scrolling. Because the
mpv code waits precisely on presentation time, the loop would timeout on
occasion instead of receiving the frame callback. This would then lead
to a skipped frame when rendering and thus causing stuttering.
The fix is simple: just only count consecutive timeouts as not receiving
frame callback. If a compositor holds the mpv buffer slightly longer to
avoid tearing, then we will definitely receive frame callback on the
next round of the render loop. This logic also appears to be sound for
plasma (funfact: Plasma always returns frame callback even when the
window is hidden. Not sure what's up with that, but luckily it doesn't
matter to us.), so get rid of the goofy 1/vblank_time thing and just
keep it a simple > 1 check.
Checking against 1.0 is wrong for this code, because it's in an absolute
luminance scale relative to reference white. We should be normalizing
this by `dst.sig_peak`.
This is actually a very nice simplification that should have been
thought of years ago (sue me). In a nutshell, the story with the
wayland code is that the frame callback and swap buffer behavior doesn't
fit very well with mpv's rendering loop. It's been refactored/changed
quite a few times over the years and works well enough but things could
be better. The current iteration works with an external swapchain to
check if we have frame callback before deciding whether or not to
render. This logic was implemented in both egl and vulkan.
This does have its warts however. There's some hidden state detection
logic which works but is kind of ugly. Since wayland doesn't allow
clients to know if they are actually visible (questionable but
whatever), you can just reasonably assume that if a bunch of callbacks
are missed in a row, you're probably not visible. That's fine, but it is
indeed less than ideal since the threshold is basically entirely
arbitrary and mpv does do a few wasteful renders before it decides that
the window is actually hidden.
The biggest urk in the vo_wayland_wait_frame is the use of
wl_display_roundtrip. Wayland developers would probably be offended by
the way mpv abuses that function, but essentially it was a way to have
semi-blocking behavior needed for display-resample to work. Since the
swap interval must be 0 on wayland (otherwise it will block the entire
player's rendering loop), we need some other way to wait on vsync. The
idea here was to dispatch and poll a bunch of wayland events, wait (with
a timeout) until we get frame callback, and then wait for the compositor
to process it. That pretty much perfectly waits on vsync and lets us
keep all the good timings and all that jazz that we want for mpv. The
problem is that wl_display_roundtrip is conceptually a bad function. It
can internally call wl_display_dispatch which in certain instances,
empty event queue, will block forever. Now strictly speaking, this
probably will never, ever happen (once I was able to to trigger it by
hardcoding an error into a compositor), but ideally
vo_wayland_wait_frame should never infinitely block and stall the
player. Unfortunately, removing that function always lead to problems
with timings and unsteady vsync intervals so it survived many refactors.
Until now, of course. In wayland, the ideal is to never do wasteful
rendering (i.e. don't render if the window isn't visible). Instead of
wrestling around with hidden states and possible missed vblanks, let's
rearrange the wayland rendering logic so we only ever draw a frame when
the frame callback is returned to use (within a reasonable timeout to
avoid blocking forever).
This slight rearrangement of the wait allows for several simplifications
to be made. Namely, wl_display_roundtrip stops being needed. Instead, we
can rely entirely on totally nonblocking calls (dispatch_pending, flush,
and so on). We still need to poll the fd here to actually get the frame
callback event from the compositor, but there's no longer any reason to
do extra waiting. As soon as we get the callback, we immediately draw.
This works quite well and has stable vsync (display-resample and audio).
Additionally, all of the logic about hidden states is no longer needed.
If vo_wayland_wait_frame times out, it's okay to assume immediately that
the window is not visible and skip rendering.
Unfortunately, there's one limitation on this new approach. It will only
work correctly if the compositor implements presentation time. That
means a reduced version of the old way still has to be carried around in
vo_wayland_wait_frame. So if the compositor has no presentation time,
then we are forced to use wl_display_roundtrip and juggle some funny
assumptions about whether or not the window is hidden or not. Plasma is
the only real notable compositor without presentation time at this stage
so perhaps this "legacy" mechanism could be removed in the future.
when using the bundle with activated big enough cache, very slow and
wasteful memory allocations lead to jittery playback and lot of dropped
frames. the cache had to have a certain size so it would constantly
allocate new memory to reproduce this. this never happens when started
from the terminal.
the source of the problem is a different malloc allocation policy,
MALLOC_NANO, that allocated a huge amount of virtual memory without
actually using it. the usage was between 0% to 25% of that virtual
memory. the binaries allocation policy on the other hand used >80% of
that allocated virtual memory and was a lot more efficient, it would use
MALLOC_TINY instead.
this is fixed by setting the MallocNanoZone environment variable to 0
to use the V1 of the allocation policy. when started from the bundle via
launchd this is forced to 1 and V2 policy which causes this problem.

Shows uploader, channel, description fields. This works only if the
media media is constructed as EDL (for youtube it usually does this),
and if the all_formats option is not set to true (does anyone even use
it?). The former usually happens because youtube serves audio and video
separately, though it will not for live HLS/DASH. The latter uses
delayed media opening, which breaks the global_tags mechanism (see
previous commit).
Add new header which shows up as tags/metadata (associated with
--display-tags). The way this is added means it doesn't always work,
because root->meta (see code) can be NULL for some absurd reason. But it
works for the one case I intended to use it (ytdl_hook, see next
commit), though only in default configurations.
When trying to use completion for mpv binaries specified with some shell
glob, e.g. ~/dev/mpv/build/mpv, the current code doesn't substitute the
homedir prefix into the path name, resulting in runtime errors about
the file '~/dev/mpv/build/mpv' not being found.
The simple fixed is to use $~var instead of $var whenever expanding the
filename, which performs the same globbing that would otherwise be
performed when executing the command.
This reverts commit b8156a9a86.
Apparently there are two problems here. One on Linux (fixed by the
original change and this revert) and one on alternative-medicine-Job's
OS. Since the latter has deprecated OpenGL and OpenGL is a second-class
citizen, I think it's better to prefer the fix for a platform that is
still alive.
When inserting vf_sub, the VO OSD is directed not to draw itself. But
this flag was never unset, even when removing vf_sub.
The fix is pretty shit, but appears to work.
Switching to a new file while keeping the AO didn't update the volume.
While there's an explicit audio_update_volume() call in
reinit_audio_chain_src(), it doesn't work, because at that point
ao_chain->ao is still NULL, and it does nothing. That's pretty weird and
might cause other problems (what happens if you try to mute while the AO
is "floating"?). Regarding gapless, trying to use the AO gain for
replaygain is also gross nonsense, because the new replaygain computed
gain would affect audio from the previous file. It looks like replaygain
should be in an af_volume filter maybe. On the other hand, I enjoy
setting ridiculous replaygain-preamp values and compensating with a low
volume setting, which would not work well if both gains were applied to
the audio independently.
For now, just add the missing call. This is orthogonal to fixing
replaygain "properly".
This reverts commit 3239e41277.
I'm fairly sure this is wrong, and my next commit should fix it
properly. I'm not really sure, though. Normally, the AO is set again
by reinit_audio_filters_and_output() after the new audio chain has
decoded a frame and knows the new format. The reason replaygain (and
apparently the thing the reverted commit tried to fix) didn't work is
because they work asynchronously to the audio played by the AO (i.e.
buggy and hard to fix).
For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES
and use it to obtain the current display's resolution from each
vo/windowing backend if applicable. Users can then access the current
display resolution as display-width and display-height as per the client
api. Note that macOS/cocoa was not attempted in this commit since the
author has no clue how to write swift.
This commit describes more accurately what currently gets disabled
by this option - specifically also keys from mp.add_key_binding.
It's not necessarily the best behavior because libmpv clients might
want to disable mpv's own builtin keybindings while still allowing
scripts to define keys which `input.conf' can override.
In the future we might exclude mp.add_key_binding from this option,
but for now at least document this option accurately.

3909e4cdfc seems to have replaced this 0.5 constant by 0.75, using its
presence in glumpy as justification.
0.75 is clearly a bug in glumpy, as its own source code doesn't even

this window I could find uses 0.5, including e.g. ImageMagick.

Fixes#8801
We now have at least 3 scripting APIs which are trivial wrappers
around properties: mp.get_mouse_pos, utils.getcwd, utils.getpid.
After some discussion on IRC it was decided that it's easier for us to
maintain them as trivial wrappers than to deprecate them and inflict
pain on users and script authors, so currently no plan to deprecate.
Some subproperties in osd-dimensions were returned as doubles despite
actually being integers. Additionally, correct a highly misleading line
in the osd-width/osd-height documentation.
This fixes a bug where using boxvideo with showfullscreen=no or
showwindowed=no resulted in the margins not resetting when the OSC
wasn't visible.
For example, using:
script-opts=osc-visibility=always,osc-boxvideo=yes,osc-showfullscreen=no
and then going fullscreen would make the OSC disappear but the video
margins would remain. This is because boxvideo was missing a dependence
on the showfullscreen and showwindowed user options.
This is fixed by adding the corresponding conditions to update_margins()
and setting state.marginsREQ on fullscreen changes. update_margins() is
called on tick() if there's a margins update pending, which guarantees
the boxvideo margins are reset appropriately.
It turns out that if a user specifies fullscreen=yes and a width/height
in an autoprofile, the compositor can execute its toplevel listener
event. This can happen before we have any mpv window rendered at all so
we end up performing a bunch of geometry operations and state checks
when we shouldn't. It subtly messes up a lot of things like state
detection. Just return from this function if the geometry has no width
or height yet.
Clearing state.osd.data with an empty string at render_wipe() fixes an
issue where changing the OSC visibility from "never" directly to
"always" didn't immediately update the display when the player was
paused. This could be verified by starting the player with
`--script-opts=osc-visibility=always --pause` and then running
`script-message osc-visibility never` followed by
`script-message osc-visibility always`.
Removing the overlay without changing the contents meant the overlay
wouldn't update and display when enabled again until the fields changed
in some way (e.g. seeking, mousing over the OSC area, etc.). Clearing
state.osd.data before removal of the OSC makes sure set_osd doesn't
return on re-enable and instead displays the OSC immediately as the data
is now different.
render_wipe() is now also used when the OSC needs to be cleared at
tick() as using set_osd to clear it with an empty string did not call
state.osd:remove() which can allow cleanups related to bitmap memory
allocations etc.
this is a regression of af26402, where we changed the geometry
calculation to use the visible frame and consider its origin. though the
origin is not screen relative but relative to the main screen. the rest
of the code expects a screen relative rectangle. because of that windows
would be placed out of the screen bounds when not on the main screen.
recalculate to origin to be screen relative and use those values for the
rest of the calculations. to make the code a bit more comprehensible
be a bit more explicit about what is done where with temporary variables
and comments. also move the mp_rect calculation that moves the origin
and flips the y position to a separate function, so we can reuse it
later.
The fit_on_screen logic was a bit twisted. Simplify it a bit
and update few comments to explain better what it's used for.
Note that the new logic is not identical to before, but its intent
should now be clearer. This means there might be regressions or
improvements at edge cases. If followup fixes are needed, then we
should keep the intent clear. Most likely though that it's fine.
fit_on_screen is called only from reinit_window_state.
Move the yes/no logic unmodified from fit_on_screen to
reinit_window_state, and remove the w32->parent condition because it's
already checked earlier at reinit_window_state.
Previously, because the video (client area) was centered but the top
and bottom borders are uneven (title is taller), then if the window
is shrunk vertically to just-fit the desktop - the top edge of the
title bar ended above the top edge of the display.
This is a state which Windows prevents during manual move, but
apparently it's not rejected at the Windows API.
Now we ensure it doesn't happen, and nudge the window down to align
the top edges if necessary.
This is a commulative regression of commits 981048e0 and 364af7c6.
To clarify functionality, this includes a no-op change: fit_rect was
renamed to fit_rect_size and it now takes explicit width and height,
because it only used the width/height of rc2 anyway.
Fixes#6695
The accurate description of this option was:
- fit-border is enabled by default. When disabled, it adds a bug where
if the window has borders and mpv shrinks it to fit the desktop, then
the calculation ignores the borders and adds incorrect video crop.
The option was added at commits 70f64f3c and 949247d6, in order to
solve an issue (#2935) where if mpv wanted to display a video with
size WxH, then w32_common.c incorrectly set the window to WxH, while
down-scaling the video slightly to fit (even with small sizes).
It was addressed with a new option which is enabled by default, but
does the right thing (sets the client area to WxH) only when disabled,
so that everyone who prefers their video slightly downscaled could
keep their default behavior.
(#2935 also addressed an off-by-one issue, fixed before fit-border)
While disabling the option did avoid unnecessary downscaling, it also
added a bug when disabled: the borders are no longer taken into
account when the size is too big for the desktop. Most users don't
notice and are unaffected as it's enabled by default.
Shortly later (981048e0) the core issue is fixed, and now the client
area is correctly set to WxH instead of the window (and together with
the three following commits which center the video, adds a new bug
where the window title can be outside the display - addressed next).
However, fit-border remained, now without any effect, except that it
still has the same bug when disabled and the window is too big.
Later code changes and refactoring preserved this issue with great
attention to details, and it remained in identical form until now.
Simply rip out fit-border.
See #8137 for justification.
This is not ideal, because a large cache results in a lot of `strcmp`
invocations for every single shader invocation. But it's way better than
resulting in a lot of shader recompilations for every single shader
invocation.
The only reason I don't want to uncap it altogether is because there are
conceivable edge cases in which users load dynamically generated shaders
with updated parameters (indeed, I've seen IRC discussions to this
effect), and in this case, we don't want to grow the cache infinitely as
a result of something like a floating point parameter being continuously
updated. (Never mind that this *would* actually trigger worst case
behavior for the `strcmp`, since the updated float constant is likely to
be near the bottom of the shader body)
Whatever. vo_placebo will liberate us all in the end.
The wayland code uses a heuristic to determine whether or not the mpv
window is hidden since the xdg-shell protocol does not provide a way for
a client to directly know this. We don't render with the frame callback
function for various, complicated reasons but the tl;dr is that it
doesn't work well with mpv's core (maybe an essay should be written on
this one day).
Currently, the aforementioned heuristic considers a window hidden if we
miss more frames in a row than the display's current refresh rate
(completely arbitrary number). However, the wayland protocol does allow
for the display's refresh rate to be 0 in certain cases (like a virtual
output). This completely wrecks the heuristic and basically causes only
every other frame to be rendered (real world example: nested sway
sessions).
Instead let's slightly redesign this mechanism to be a little smarter.
For coming up with the vblank time (to predict when to timeout on the
wait function), instead use the vsync interval calculated using
presentation time. That is the most accurate measure available. If that
number is not available/invalid, then we try to use the vsync interval
predicted by the presentation event.
If we still don't have that (i.e. no presentation time supported by the
compositor), we can instead use the old way of using the expected vsync
interval from the display's reported refresh rate. If somehow we still
do not have a usable number, then just give up and makeup shit. Note
that at this point we could technically ask the vo for the estimated
vsync jitter, but that would involve locking/unlocking vo which sounds
horrifying. Ideally, you never reach here.
See https://github.com/swaywm/wlroots/issues/2566 for the actual target
of this fix. wlroots uses presentation time so in practice we are mostly
just using that calculated vsync interval number.
Seems to be a slight corner case with the audio API rewrite. When
switching from one file to another one, the volume of the ao would never
be set because the audio chain's ao wasn't set. This caused a bug with
the reset-set-on-file option. The volume/property would be correctly set
internally, but the gain was not actually set when the file switched.
Fixes#8287.
The wayland output listener can update whenever something about the
output changes (resolution, scale). Currently, the mpv VO updates
correctly when the refresh rate changes, but changes of both scale and
resolution were not considered. This causes a bug in certain cases like
the mouse surface not being shown at certain scale factors due to the
cursor scale not being updated correctly. Also autofit type options
would not update if the resolution changes.
To fix this, we must always reset the window geometry and wl scaling
whenever the output event occurs on wl->current_output. There is no way
to know precisely what changed from the previous state, so all of the
parameters must be reset and then resized.
As an aside, this apparently doesn't fix all cursor problem as there's
apparently a bug in libwayland-cursor(*). It's still something we should
be doing regardless.
*: https://gitlab.freedesktop.org/wayland/wayland/-/issues/194
So apparently this property had existed since 2019. Internally, it's
used as a part of the console.lua script for scaling. Yours truly
somehow didn't bat an eye at the fact that the text in the console was
super small (made worse by the fact that xwayland does scale) and just
ignored it for all this time. Oh well.
To report dpi changes to mpv's core, we need to use VO_EVENT_DPI in a
couple of places. One place is, of course, the surface listener if the
scale value reported by the wayland server changes. The other place is
in the very first reconfig since mpv's core will not find the correct
scale value until we actually get a wl_output from the wayland server.
This fixes audio encoding crashing under ASan.
When extended_data != data, FFmpeg copies more pointers from
extended_data (= the number of channels) than there really
are for non-planar formats (= exactly 1), but that's not our fault.
Regardless, this commit makes it work in all common cases.
The args struct is reused to attempt opening an URL with
different stream layers, overwriting args->url not only
breaks this but also causes the freed buffer to be used again.
Before this commit, the user could specify a printf format string
which wasn't verified, and could result in:
- Undefined behavior due to missing or non-matching arguments.
- Buffer overflow due to untested result length.
The offending code was added at commit 103a9609 (2002, mplayer svn):
git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@4566 b3059339-0415-0410-9bf9-f77b7e298cf2
It moved around but was not modified meaningfully until now.
Now we reject all conversion specifiers at the format except %%
and a simple subset of the valid specifiers. Also, we now use
snprintf to avoid buffer overflow.
The format string is provided by the user as part of mf:// URI.

When mpv attempts to play a video that is, on average, 60 FPS on a
display that is not exactly 60.00 Hz, two options try to fight each
other: `video-sync-max-video-change` and `interpolation-threshold`.
Normally, container FPS in something such as an .mp4 or a .mkv is
precise enough such that the video can be retimed exactly to the display
Hz and interpolation is not activated.
In the case of something like certain live streaming videos or other scenario
where container FPS is not known, the default option of 0.0001 for
`interpolation-threshold` is extremely low, and while
`video-sync-max-video-change` retimes the video to what it approximately
knows as the "real" FPS, this may or may not be outside of
`interpolation-threshold`'s logic at any given time, which causes
interpolation to be frequently flipped on and off giving an appearance
of stuttering or repeated frames that is oftern quite jarring and makes
a video unwatchable.
This commit changes the default of `interpolation-threshold` to 0.01,
which is the same value as `video-sync-max-video-change`, and guarantees
that if the user accepts a video being retimed to match the display,
they do not additionally have to worry about a much more
precise interpolation threshold randomly flipping on or off. No internal
logic is changed so setting `interpolation-threshold` to -1 will still
disable this logic entirely and always enable interpolation.
The documentation has been updated to reflect this change and give
context to the user for which scenarios they might want to disable
`interpolation-threshold` logic or change it to a smaller value.
Today, validation is only possible for string type options. But there's
no particular reason why it needs to be restricted in this way, and
there are potential uses, to allow other options to be validated
without forcing the option to have to reimplement parsing from
scratch.
The first part, simply making the validation function an explicit
field instead of overloading priv is simple enough. But if we only do
that, then the validation function still needs to deal with the raw
pre-parsed string. Instead, we want to allow the value to be parsed
before it is validated. That in turn leads to us having validator
functions that should be type aware. Unfortunately, that means we need
to keep the explicit macro like OPT_STRING_VALIDATE() as a way to
enforce the correct typing of the function. Otherwise, we'd have to
have the validator take a void * and hope the implementation can cast
it correctly.
For help, we don't have this problem, as help doesn't look at the
value.
Then, we turn validators that are really help generators into explicit
help functions and where a validator is help + validation, we split
them into two parts.
I have, however, left functions that need to query information for both
help and validation as single functions to avoid code duplication.
In this change, I have not added an other OPT_FOO_VALIDATE() macros as
they are not needed, but I will add some in a separate change to
illustrate the pattern.
This fixes an issue where dithering was effectively broken on libplacebo
versions >= 103 because the dither texture was being sampled with
edge-clamped rather than repeating semantics.
Changes:
- code refactored;
- mixer options removed;
- new mpv sound API used;
- add sound devices detect (mpv --audio-device=help will show all available devices);
- only OSSv4 supported now;
Tested on FreeBSD 12.2 amd64.
There was a simple oversight that meant audio outputs were
uninitialized during an encoding, which is not allowed, the encoding
would stop with numerous errors.
I added a single line to prevent the call of uninit_audio_out in
reinit_audio_chain if the encoder was active and this appears to have
fixed the problem without breaking anything else.

This makes the behavior of all control messages consistent,

Muting the stream also directly triggers an update to the OSD.
When not waiting for the command completion this read of the mute

The wayland code takes mouse dragging into account in order to trigger a
client-side request for a window move or window resize. According to the
xdg-shell spec*, "[t]he server may ignore move[/resize] requests
depending on the state of the surface (e.g. fullscreen or maximized)".
Since it is not actually a hard requirement, that means the compositor
could actually respond to a clientside move/resize request even if the
mpv window was fullscreen. For example, it was pointed out that in sway,
if mpv is a floating window, you could drag it around off screen even
though the window is fullscreen.
This kind of behavior does not really have any practical use. A user can
should pan a video if he/she wishes to move its orientation while
fullscreen (or maximized for that manner). Naturally, a maximized or
fullscreened window should never be manually resized (every compositor
likely ignores this anyway). The fix is to simply just not trigger the
smecial mouse dragging case if the wayland surface is fullscreened or
maximized.

It's about a year old, and packaged pretty much everywhere that bothers
to package libplacebo at all. Older versions are only a thing on LTS,
which will probably also use older mpv so it works out.
Starting with v2.72.0, libplacebo validates all of its parameters
internally and turns them into function failures. Doing it twice is
awfully redundant, so we can drop the parameter validation.
Also allows us to drop some preprocessor macros.
if log-file and really-quiet options were used together it could lead to
a completely empty log-file. this is unexpected because we need the
log-file option to work in all cases and produces at least a log of
verbosity -v -v. this is a regression of commit
a600d152d2
move the really quiet check back up, so it's set before the evaluation
of the actual log level, where check for log file, terminal, etc take
place.
the slider on the touch bar was always updated when any of the related
properties changed their value. this is partially dependent on the
refresh rate of the video, in the case of time-pos. too many updates to
touch bar impact the render performance.
to prevent this we only update the slider when necessary, when the touch
bar or the touch bar item is visible. the touch bar items only need a
granularity of seconds without any decimals, but the time-pos property
provides a granularity with decimals. we floor those values and only
update the touch bar items when we have at least a 1 second difference.
we also check for the visibility of the touch bar and its items.
Fixes#8477
the NSSliderTouchBarItem seem to be broken in a way it can't be fixed.
it has constraints set by default that can't be removed and lead to
warnings and render performance regressions.
instead of using the preconfigured NSSliderTouchBarItem we use a custom
touch bar item (NSCustomTouchBarItem) with a slider, which essential are
the same. this way we can configure our constraints ourselves, which
aren't needed in the first place.
Fixes: #7047
initialising UnsafeMutableRawPointer the way we did won't free those
pointers and we get dangling pointers. explicitly define a scope those
pointers are alive and auto freed.
this drops support for swift <4.1 and with this support for xcode <=9.2.
this was the last setup that is officially working on macOS 10.12.
our old legacy build macOS 10.12 + xcode 9.2 is replaced by macOS 10.13
+ xcode 9.4.1 with swift 4.1. the macOS 10.13 + xcode 10.1 VM is
replaced by the latest macOS 10.14 + xcode 11.3.1 VM. this is the oldest
version officially supported by Apple.
this is in preparations for the following commit.
the pointer used to initialise the respective structs is only guaranteed
to be alive within this constructor. the struct itself is used later and
the data it points to, is not guaranteed to be the same.
to fix this we define a scope that pointer is definitely valid and use
it within this scope. a helper function was added to get the pointers
for several data at once. otherwise we would need to nest
withUnsafeMutableBytes several times, which would make it hard to read.
Apple has decided that Mac OS X is now named macOS for the time
being. For consistency, it makes sense to use the same name for the
operating system in all places where it occurs. This commit renames
OS X to macOS in the documentation in places where it was otherwise
still using the old name.
Where X is any ASCII char chosen by the user. An argument is only
interpreted as custom-quoted if it starts with '!' and the line doesn't
end right after it. Custom quotes don't interpret backslash-escape.
This change only affects command arguments which mpv parses (not array
commands), and not tokens before the arguments (where applicable - key
name, input section, command prefixes, command name).
This enables us to get more of a message than just "Download failed.",
possibly helping people help themselves to get the download going.

Should result in: "You manually enabled the feature 'lua', but the
autodetection check failed."
The moved bit of code was probably intended to do that all along, but it
was running too late, so the code that actually checked for Lua didn't
know it was explicitly asked for and quietly disabled it if not found.
Oversight when the modifier checking was split out to a separate
function. Instead of immediately returning on a match, be sure to loop
through all modifiers and catch every single one that is pressed before
we return them.
currently we use the whole screen rectangle to calculate the window
geometry. this doesn't take the menu bar or the Dock into account.
by default use the visible screen rectangle instead. this is also a
change in behaviour, since the window can't be placed outside of this
rectangle anymore. also add an option to change to the old behaviour,
because it can still be useful in certain cases, like placing the window
directly underneath the menu bar when used a desktop background.
Fixes#8272
when exiting fullscreen we set the window frame to a aspect fit frame of
the fullscreen frame to prevent aspect ration problems when animating.
though that intermediate frame was set too early and before the system
knew we already exited the fullscreen. because of that the frame we set
could not be properly set and its origin was defaulted to the bottom
left corner for exactly one display refresh and only after that the
wanted frame was set. this led to a (dark) grey area on the right or
top depending on the aspect ratio difference of the screen and video.
to prevent this set the intermediate frame in the animation group to
make it sync with the system's fullscreen behaviour.
Fixes#8371
Originally when presentation time was implemented, the frame callback
and presentation feedback functions were called in each rendering api's
separate backend (egl and vulkan). This meant that their respective
structs were basically copy and pasted across both files. Plus later
vo_wlshm started using frame callbacks too. Things got refactored a few
times and it turns out there's actually no need to have these things
separate anymore. The frame callback can just be initialized in
vo_wayland_init and then everything else will follow from there. Just
move all of this code to wayland_common and get rid of the duplication.
Sidenote: This means that vo_wlshm can actually receive presentation
feedback now. It's really simple to do so might as well. See the next
commit.
If the window is maximized, we can't change the size immediately. In
that case, we set a bool and wait for the state to change before
triggering the resize.
Additionally, do some cleanups in the resize/autofitting code to make
sure we don't do any wasteful VO_EVENT_RESIZE calls. Note that if
set_geometry is called, we must always perform a resize.
--alpha=yes doesn't affect only transparent videos and images, but also
the background. I spent time researching how to implement transparent
backgrounds and had no idea that they already worked at least on
Wayland.
Background transparency will work on X11 when
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/2376 is
merged. It doesn't work on Windows. No idea about macOS. Either way,
this paragraph already says that it only works on certain environments
twice.

With the current wording, I thought that playlist-prefetch doesn't
prefetch the next url within a playlist of m3u8 urls, but it makes a big
difference, and I would have enabled it earlier if it wasn't for this
paragraph.
This makes it clear that you can prefetch any file, but that it won't
prefill the cache with the video data. This is true for any video,
there's nothing unique about HLS streams in the behavior of this option.
There's a bit of a catch-22 in the wayland backend. mpv needs to know
several things about the wl_output the surface is on (geometry, scale,
etc.) for lots of its options. You still have to render something
somewhere before you can know what wl_output the surface is actually on.
So this means that when initializing the player, it is entirely possible
to calculate initial parameters using the wrong wl_output. The surface
listener is what will eventually correct this and pick the correct
output. However not everything was technically working correctly in a
multi-output setup.
The first rule here is to rework find_output so that it returns a
vo_wayland_output instead of internally setting wl->current_output. The
reason is simply because the output found here is not guaranteed to be
the output the surface is actually on. Note that for initialization of
the player, we must set the output returned from this function as the
wl->current_output even if it is not technically correct. The surface
listener will fix it later.
vo_wayland_reconfig has to confusingly serve two roles. It must ensure
some wayland-related things are configured as well as setup things for
mpv's vo. The various functions are shuffled around and some things are
removed here which has subtle implications. For instance, there's no
reason to always set the buffer scale. It only needs to be done once
(when the wl->current_output is being created). A roundtrip needs to be
done once after a wl_surface_commit to ensure there are no configuration
errors.
surface_handle_enter is now handles two different things: scaling as
well as mpv's autofit/geometry options. When a surface enters a new
output, the new scaling value is applied to all of the geometry-related
structs (previously, this wasn't done). This ensures, in a multi-monitor
case with mixed scale values, the surface is rescaled correctly to the
actual output it is on if the initial selection of wl->current_output is
incorrect.
Additionally, autofit/geometry values are recalculated if they exist.
This means that dragging a surface across different outputs will autofit
correctly to the new output and not always be "stuck" on the old one.
A very astute observer may notice that set_buffer_scale isn't set when
the surface enters a new output. The API doesn't really indicate this,
but a WAYLAND_DEBUG log reveals that the compositor (well at least
sway/wlroots anyway) magically sets this for you. That's quite fortunate
because setting in the surface handler caused all sorts of problems.
in the original commit, that removed the conditional clearing, an
incorrect assumption was made that clearing "should be practically free"
and can be done always. though, at least on macOS + intel this can have
a performance impact of up to 50% increased usage. it might have an
impact on other platforms and setups as well, but this is unconfirmed.
the reason for removing the conditional clearing was to partially work
around a driver bug on very specific setups, X11 with amdgpu and OpenGL,
to clear garbled frames on start. though it still has issues with
garbled frames in other situation like fullscreening. there is also an
open bug report on the mesa bug tracker about this. setting the
radeonsi_zerovram flag works around all of those issues.
since the flag works around all these issues and the original fix
doesn't work completely we revert it and keep our optimisation.
Fixes#8273
the screen-name and fs-screen-name option allow for specifying screens
based on their name. this is the name of the NSScreen and also reported
by the VOCTRL_GET_DISPLAY_NAMES event. the old screen and fs-screen
options by id, respectively, are preferred over these new ones.
In wayland, setting the surface on a specific monitor only works in
fullscreen so only --fs-screen-name can be implemented. Like with x11,
we prefer --fs-screen over --fs-screen-name if it is set. This may be
more useful than setting by ids because there's no guaranteed order in
which screens are added in wayland. In wayland, the name used here is
the model name detected by the output_listener.
The --screen-name and --fs-screen-name options allow for specifying
screens based on their name. For x11, this is the display name reported
by xrandr. --screen-name and --fs-screen-name mimic the --screen and
--fs-screen options respectively. If --screen is set, then --screen-name
will always do nothing. Likewise, --fs-screen-name does nothing if
--fs-screen is set.
Simple groundwork for adding a couple of user options that allow
selecting the screen with a string name. The next two commits implements
these options for xorg and wayland.
While this says that _ is replaced with -, it doesn't say that you HAVE
to use _. This isn't obvious and I didn't understand why my profile
conditions with - weren't working at first. Seeing as the person who
reproted #8324 ran into this as well, this may be worth clarifying.
Zlib has had a .pc file since 2010, and the default search paths we use
here can break the build on some distros (notably openSUSE Tumbleweed,
which our Travis builds use). Just check pkg-config instead.
Our canvas size calculation is affected by few factors, and rounded
down more than once - which can result in 0 width or (more typically)
height - e.g. when terminal height is one row.
If the width or height are 0 then all bets are off, so simply skip
the setups and rendering on this case. We can still recover
automatically if the terminal is resized to become bigger.
The obvious approach would be SIGWINCH, however, integrating it would
be tricky, so instead we simply poll the size on draw_frame.
This means the image won't resize automatically when still - e.g.
cover art or when paused, though it would re-fit on OSD changes.
This is commonly used by UHD/HDR sources, and mpv hilariously ignores it
up until now, just blindly mapping it to MP_CHROMA_AUTO without even so
much as a warning message.
It would be justified to add all the other chroma locations as well, but
I'm lazy and just wanted to quickly fix this bug.
homebrew is removing 10.13 support and some of the dependencies start

The reference is allocated at reconfig and happens at least once (and
leaked at least once), but can also be called more, e.g. on zoom or
pan-and-scan changes.
The reference is allocated at reconfig (and leaked at least once), but
could theoretically be called more than once by mpv, or in the future
when the tct code is enhanced to hande e.g. pan-and-scan changes.
testdither was being created irrespective of whether
opt_fixedpal is set or not. In case of opt_fixedpal=1,
testdither is not used in the `prepare_static_palette`
code. Hence only initialize it when opt_fixedpal is 0.
In sixel_dither_initialize, replace 3 with the libsixel
SIXEL_PIXELFORMAT_RGB888. Also in sixel_encode, the 4th
parameter is supposed to be depth, which also happens
to be the value of PIXELFORMAT_RGB888, so replacing that
constant with the depth value.
Since 0.33.0 mpv does not support python2. This commit removes
python2 support from the file completely with the following
changes:
- __future__ import of print_function is python2 only
- unicode literals are legacy in python3
- 'sys.version_info.major < 3' check is redundant
In 0.33.0 python2 support has been removed from mpv's build system. This
commit removes python2 compatibility code from bootstrap.py with the
following changes:
- __future__ import for print_function is not needed
- urllib2 is python2 only
For two reasons:
1. It was counter intuitive that there's an "auto" value (which is
actually a libsixel value and not an mpv one), but it's not the
default value - our default was Atkinson.
2. "auto" provides better dithering than Atkinson with libsixel, which
is especially noticeable with smooth gradients - where Atkinson has
visible banding.
In libsixel 1.8.2 the "auto" value maps to Atkinson if the output
palette has up to 16 colors, or to Floyd-Steinberg otherwise (e.g.
using fixed palette with 256 colors chooses Floyd-Steinberg).
The issue was that we only uploaded the palette to the terminal when it
changed (once on init with fixed palette, every frame with dynamic
palette with trheshold=-1, only on scene change with threshold >= 0).
Now we upload it on every frame, and it seems to fix the mlterm image
corruption both with fixed palette and also with dynamic palette with
threshold (i.e. at frames which did not upload a palette).
It's not entirely clear why it's required with mlterm.
It would seem that the palette which libsixel uses with fixed palette
matches the built in default palette in xterm, but not in mlterm.
With dynamic palette we can guess that mlterm resets the palette after a
sixel image, but that's not confirmed.
Uploading the palette on every frame doesn't seem to slow down xterm
when using fixed palette - not clear yet why uploading a different
palette (when using fixedpalette=no) slows it down while same palette
on every frame doesn't.
In mlterm there's no slowdown either way - and now also no corruption.
By default we still clear the screen, but now it's possible to leave the
last sixel image on screen.
Allows mpv to be used as img2sixel of sorts, but with our auto-fit and
various mpv scaling/filters etc.
When mpv is in the background because it was started with
`mpv foo.mp3 &`, or the user did ctrl+z bg, and is then brought to the
foreground with fg, it buffers input until you press enter. This makes
it accept input almost immediately. Having a short interval isn't
important, since input is buffered until the next loop iteration.
Closes#8120.
Trigraphs such as "??=" (which are enabled by default with -std=c11)
can mess up strings, so avoid them entirely by escaping question marks.
This also drops Python 2 compatibility from file2string, making the
change to the waf rule necessary. The input file is now opened in
binary mode which is also more correct versus the old text mode
which just happened to work even on binary files.
This reverts commit 3d17e19c2c.
The effect of turning off this setting is that mpv doesn't tell libass what
the video stream's resolution is. This happens to result in some files having
their transforms scaled in ways that give higher performance (as described
in #7435) because libass happened to guess a video resolution that resulted
in transforms yielding smaller bitmaps, but it's just as easy for the opposite
to happen depending on the resolutions and effects involved.
The option's name is also somewhat misleading: setting the storage size affects
blur, but it also affects stroke (which is far more important for the vast
majority of scripts) and 3D transforms (which look very screwy when done wrong).
Upstream waf still ships with the default interpreter being "python",
though the script works with both Python 2 and Python 3 (they're not
changing the default choice during 2.0.x releases for compatibility
reasons apparently). Add code to bootstrap.py to change the
interpreter from "python" to "python3" when downloading the "waf"
file.
Running any mpv code under Python 2 should be considered unsupported
in the future (and any code added need not work under Python 2).
remove the hardcoded swift target version and move the version
restriction to configure. this was a bad idea anyway and could lead to
mismatched object files between obj-c and swift. fix travis 10.12 legacy
build.
also update the SDK version parser to handle the new macOS 11 scheme.
Fixes#8281
Currently in mpv functions sixel failures return the
value status which is of type SIXELSTATUS. So changing
it to -1 which is explicit and compatible with mpv.
Also log the errors using MP_ERR/MP_LOG with the
error string returned by libsixel to have more info.
fixedpalette seems to be slightly faster than dynamic
palette, and also in mlterm it avoids corruption of
too bright values overflowing to black. Hence setting
it to be default choice instead of dynamic palette.
Resize the image based on the dimensions reported by
vo_get_src_dst_rects to correctly handle aspect ratio
that might be set/ignored.
Added pad-x and pad-y options for padding.
These options will be used to remove the extra padding.
Some terminals report the padding of 2px in the ioctl
dimensions which can't be used for displaying sixel
output. These options can be used for fine tuning
the output video resolution.
Now all the terminal size detection and calculation logic
is done in a single function at resize. Also top and left
values are computed from the dst_rect parameters to simplify
the logic for the aspect ratio based centering.
Additionally vo-sixel-rows and vo-sixel-cols options
have been added to enable the user to override the values
in case of failures with get_terminal_size2.
This commit also adds ability to handle video zoom correctly.
Whenever video-zoom is triggered, the src and dst rects
will be updated. Scaling seems to work well now.
This has no changes to mpv sixel playback behaviour.
This is required because currently the offset values
and the resolutions are being overwritten and not
remembered.
Having them in the same line made it hard to read them in the man page
since they are formatted in the same way and they look as though they
are only one definition.
Recent versions of mpv have applied security checks to --playlist
that previously only existed if playlist files were played as an
input directly. This commit documents this change and how to work
around it, in the event that playlist files are trusted.
Previously the mouse command never ended up in enter/leave keypresses
for the default section even when logically required, because input.c
does not know the area of the default section and relies on something
feeding it ENTER/LEAVE presses - which the VO typically does but the
mouse command didn't.
Now the mouse command feeds it ENTER/LEAVE if required.
It's possible to handle it differently and more consistently by:
1. reverting this commit.
2. Updating the default section area whenever the osd dimensions change.
3. Always ignore MOUSE_ENTER keys because the position is not known yet
(but MOSE_MOVE typically follows right away).
4. On mouse move: first generate ENTER/LEAVE if required.
That would guarantee consistency between mouse position and enter/leave
events but could be more sensitive to manage (the default section has
"infinite" area which is used to capture any event outside of specific
section areas), while this commit keeps consistency same as before and
depending on correct external feeding - which we now do better, even if
still not optimally (like before, it's still technically possible that
a script recieves MOUSE_ENTER and then reads the position before it got
updated after the ENTER).
Add a third field: "hover", which is updated from input.c after input
keys MP_KEY_MOUSE_LEAVE and MP_KEY_MOUSE_ENTER - which are typically
sent by the VO.
It's part of mouse-pos and not a new property because it's highly tied
to mouse-pos - it makes x/y invalid while the cursor doesn't hover the
window.
Unike mouse-move, no dummy command was generated, so we add dummy
command in order for observer notification to work even while nothing
is bound.
Like mouse-pos, clients could not detect whether the mouse pointer
hovers the window because the OSC force-binds the MOUSE_LEAVE key, and
now they can using the hover field.
The lua mp.get_mouse_pos() wrapper still returns only x, y because
that's what osc.lua needs. Other clients can simply read the property.
mp.get_mouse_pos() is undocumented and is no longer required - the
property can be used officially by any client now, however, osc.lua
uses it, and also some user scripts learnt to rely on it, so we keep
it - as a trivial wrapper around the new mouse-pos property.
This is a read-only MPV_NODE value with integer fields: x, y.
The values are unmodified from mp_input_get_mouse_pos(...).
Observer notification of this property is tied to the INPUT_PROCESSED
event, which fires after mouse move even if no command is bound
(dummy commands are generated if nothing is bound to ensure that
mp_input_get_mouse_pos returns the latest values - see ac927e39 ).
This allows clients such as JSON IPC to observe mouse position even
while the OSC is enabled - the OSC force-binds mouse move for most
of the window area, making it impossible for other clients to bind
mouse move without breaking the OSC.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
Mistakenly reverted as part of the default configuration directory
location switch-back in aa18a8e1cd.
Separation of the mpv executable directory from old_path is a
good change now that we warn about the old_config directory also
existing.

This can be viewed at page 4 of the internal stats display (i or I).
CPU time report is the same as at lua.c, but untested - doesn't seem
to work on windows - also not for lua.
TL;DR: Set env MPV_LEAK_REPORT=1 to enable js memory reporting stats.
This also almost doubles the memory usage by js scripts.
For memory reporting, we don't have enough info by default, because
even when using a custom allocator, mujs doesn't report the old size
(on free or realloc) because it doesn't track this value, and as
a result we can't track the overall size.
Our option are either to track the size of each allocation on our own,
or use talloc which tracks this value.
However, using talloc for mujs allocations adds a considerable
overhead, and almost doubles(!) the overall memory used, because each
individual allocation includes a considerable talloc header, and mujs
does many small allocations.
So our solution is that by default we behave like previously - not
using a custom allocator with mujs, and stats does not display memory
usage for js scripts.
However, if the env var MPV_LEAK_REPORT is set to 1, then we use
a custom allocator with talloc and track/report memory usage.
We can't switch allocator at runtime, so an mpv instance either tracks
or doesn't track js scripts memory usage, according to the env var.
(we could use a property and apply it whenever a new script starts,
so that it could change for newly launched scripts, but we don't).
- Explain which properties are writeable.
- Mark edition-list/N/id as writable.
- Remove (R) from some read-only properties since none of the others
have it.
- Add osd-dimension/ to its subproperties.
- options/<name> isn't read-only.
- focused works on macOS because of 82eda2e. Though it shouldn't be

The picture type is explained in /usr/include/libavutil/avutil.h
Other subproperties in /usr/include/libavutil/frame.h
And there is a more detailed explanation for repeat_pict in
/usr/include/libavcodec/avcodec.h
When possible, refer to booleans with "Whether..." since it can refer to
both yes (using input.conf and mp.get_property) and true (using the JSON
IPC or mp.get_property_native/bool), else explicitly say yes/true.
Say "true" for subprocess and osd-overlay named arguments since you
can't use them in input.conf and you will typically use them with the
boolean true in the named arguments, like the subprocess example in the
manpage does (though the string "yes" also works).
Subproperties that can't be accessed with the / syntax like
demuxer-cache-state's bof-cached and eof-cached always return true,
never yes.
Set pcm state to SND_PCM_STATE_XRUN in case -EPIPE is received,
and handle this state as per the usual logic.
This way snd_pcm_prepare gets called, and the loop continued.
Inspired by a patch posted by malc_ on #mpv.
The pointer button event had no code to handle any modifier keys. So
this meant input combinations like Shift+MTBN_LEFT did not work. Fix
this by ripping out the modifier-checking code in keyboard key event to
a separate function and using it for both the keyboard and mouse events.
In the case of the mouse, it is possible that the keyboard may not exist
so be sure to check before trying to get any modifiers. Fixes#8239.
30dcfbc is a workaround for incorrect border sizes that could occur on
sway/wlroots in certain edge cases. This seemed harmless enough, but it
turns out that on mutter the extra wl_surface_commit somehow causes the
window always go to the top left of the screen after you leave
fullscreen. No idea why this occurs, but the original commit is a
workaround a sway bug and causing regressions for other users isn't
right despite the author being biased towards sway/wlroots.
This reverts commit 30dcfbc9cb.
Based on the implementation of ffmpeg's sixel backend output written
by Hayaki Saito
https://github.com/saitoha/FFmpeg-SIXEL/blob/sixel/libavdevice/sixel.c
Sixel is a protocol to display graphics in a terminal. This commit
adds support to play videos on a sixel enabled terminal using libsixel.
With --vo=sixel, the output will be in sixel format.
The input frame will be scaled to the user specified resolution
(--vo-sixel-width and --vo-sixel-height) using swscaler and then
encoded using libsixel and output to the terminal. This method
requires high cpu and there are high frame drops for 720p and
higher resolution videos and might require using lesser colors and
have drop in quality. Docs have all the supported options listed
to fine tune the output quality.
TODO: A few parameters of libsixel such as the sixel_encode_policy
and the SIXEL_XTERM16 variables are hardcoded, might want to
expose them as command line options. Also the initialization
resolution is not automatic and if the user doesn't specify the
dimensions, it picks 320x240 as the default resolution which is not
optimal. So need to automatically pick the best fit resolution for
the current open terminal window size.
This allows keybindings such as:
a script-message-to console type "seek :0 absolute" 6
% script-message-to console type "seek absolute-percent" 6
The cursor position 0 isn't allowed because it has the weird effect of
filling the console with the text twice, leaving the cursor in the
middle.
Negative positions would put the cursor n characters before the end, and
positions greater than the text's length at the end. They seem to work
at first, but the console breaks when you move the cursor, so they
aren't allowed.
It seems that float values don't cause issues, but I'm using the
argument's floor anyway to be safe. Using >= 1 instead of > 0 ignores
values like 0.5.
The wl_pointer interface defines button argument as “a button code as
defined in the Linux kernel's linux/input-event-codes.h header file,
e.g. BTN_LEFT.”
We could #define these few buttons ourselves, but there is no system to
test it on, so for now let’s disable Wayland support on them.
This is a call to non-Linux system maintainers, please help test this
backend on your system and report issues you find, or even working
state.
Wayland’s wl_pointer interface describes the button event’s argument as
being taken from linux/input-event-codes.h, so there is no need to
include the more generic linux/input.h.
This introduces the delete-watch-later-config command, to complement
write-watch-later-config. This is an alternative to #8141.
The general problem that this change is attempting to help solve has
been described in #336, #3169 and #6574. Though persistent playback
position of a single file is generally a solved problem, this is not
the case for playlists, as described in #8138.
The motivation is facilitating intermittent playback of very large
playlists, consisting of hundreds of entries each many hours
long. Though the current "watch later" mechanism works well - provided
that the files each occur only once in that playlist, and are played
only via that playlist - the biggest issue is that the position is
lost completely should mpv exit uncleanly (e.g. due to a power
failure). Existing workarounds (in the form of Lua scripts which call
write-watch-later-config periodically) fail in the playlist case, due
to the mechanism used by mpv to determine where within a playlist to
resume playback from.
The missing puzzle piece needed to allow scripts to implement a
complete solution to this problem is simply a way to clean up the
watch-later configuration that the script asked mpv to write using
write-watch-later-config. With that in place, scripts can then
register an end-file event listener, check the stop playback reason,
and in the "eof" and "stop" case, invoke delete-watch-later-config to
delete any saved positions written by write-watch-later-config. The
script can then proceed to immediately write a new one when the next
file is loaded, which altogether allows mpv to resume from the correct
playlist and file position upon next startup.
Because events are delivered and executed asynchronously,
delete-watch-later-config takes an optional filename argument, to
allow scripts to clear watch-later configuration for files after mpv
had already moved on from playing them and proceeded to another file.
A Lua script which makes use of this change can be found here:

(A modification of the one written by @Hakkin, in that this one takes
advantage of the new command, and also saves the state immediately
when a new file is loaded.)
Testing kwinft out (kwin fork), it was discovered that sometimes it
would return a ust value of 0 which subsequently resulted in incorrect
presentation statistics (i.e. large negative numbers which are obviously
impossible). Arguably, it shouldn't return 0s, but a workaround for mpv
in this case is harmless.
As we are now on 20.04, these packages are now available in the
repositories. Additionally, they don't need to be separately pulled
in, as gcc-mingw-w64 already does that.
The original documentation here is unclear, so let's describe the
behaviour we actually have. Inspired by wm4's updated docs but
obviously not identical because we're not changing any of the
behaviours.
There have been mentions that there are apparently some bugs with
regards to possible random build failures, so bumping after a few
years sounds like an OK thing to test/do.
VOCTRL_UPDATE_RENDER_OPTS is supposed to be optional so check if it
actually exists before executing the function. Fixes a segfault when
changing the alpha value at runtime on non-wayland platforms.
7fb972f fixed transparency on x11/EGL/Mesa but happened to also break it
for wayland and nvidia. Ideally on wayland, you should just be able to
pick the right EGLConfig that has alpha but this doesn't seem to work
because reasons. So just go back to setting the EGL_ALPHA_SIZE bit if
the user asks for alpha. Apparently this worked before for nvidia as
well. The hack is to just run an eglQueryString in the x11egl context.
If it picks up Mesa as the EGL_VENDOR, then force ctx->opts.want_alpha
to 0 and let pick_xrgba_config take care of the rest.
Made possible with 00b9c81. 34b8adc let the wayland surface set an
opaque region depending on if alpha was set by the user or not. However,
there was no attempted detection for runtime changes and it is possible
(at least in wayland vulkan) to toggle the alpha on and off. So this
meant, we could be incorrectly signalling an opaque region if the user
happened to change the alpha. Additionally, add a helper function for
this and use it everywhere we want to set the opaque region.
vo_gpu has a small set of options for ra_ctx that can be set. In
practice, runtime toggling doesn't matter for most of these as they have
no effect while a video is playing. However, changing the alpha option
during runtime can actually work depending on the backend used. mpv
already detected when one of these options changed, but it made no
attempt to update the options in the ra_ctx accordingly (likely because
nothing made any use of this information). Another related change is to
add an update_render_opts to the fns and allow invidiual backends to
(optionally) use it.
efb0c5c changed the rendering logic of mpv on wayland and made it skip
rendering when it did not receive frame callback in time. The idea was
to skip rendering when the surface was hidden and be less wasteful. This
unfortunately had issues in certain instances where a frame callback
could be missed (but the window was still in view) due to imprecise
rendering (like the default audio video-sync mode). This would lead to
the video appearing to stutter since mpv would skip rendering in those
cases.
To account for this case, simply re-add an old heuristic for detecting
if a window is hidden or not since the goal is to simply not render when
a window is hidden. If the wait on the frame callback times out enough
times in a row, then we consider the window hidden and thus begin to
skip rendering then. The actual threshold to consider a surface as
hidden is completely arbitrary (greater than your monitor's refresh
rate), but it's safe enough since realistically you're not going to miss
60+ frame callbacks in a row unless the surface actually is hidden.

Pointless feature that can be done with environment variables. It was
also implemented incorrectly and broke autoprobing.
This reverts commit 015b676875.
As per the client API, a client can connect to any arbitrary wayland
socket. mpv has always just passed NULL which connected to the
compositor currently in use, but one could just as easily pass the name
of a different socket (i.e. the value of WAYLAND_DISPLAY). Here, we just
expose this argument as a user configurable option. If the user passes a
socket name that does not exist, then print a warning and fall back to
NULL.
Apparently a part of the wayland spec. A compositor may use a surface
that has set part of itself as opaque for various optimizations. For
mpv, we simply set the entire surface as opaque as long as the user has
not set alpha=yes (note: alpha is technically broken in the wayland EGL
backend at the time of this commit but oh well). wlshm is always opaque.
Fixes#8125.
Picks up files like "cover.jpg". It's made part of normal external file
loading, so I'm adding 3 new options that are direct equivalents for the
options that control loading of external subtitle and audio files. Even
though I bet nobody wants them and they just increase confusion... I
guess the world is actually hell, so this outcome should be fine.
It prefers non-specific external files like "cover.jpg" over embedded
cover art. Not sure if that's wanted or unwanted.
There's some pain over explicitly marking such files as external
pictures. This is basically an optimization: in most cases, a heuristic
would treat an image file loaded with --external-file the same (it's a
heuristic because ffmpeg can't tell us whether something is an image or
a video). However, even with this heuristic, it would decode the cover
art picture again on each seek, which would essentially slow down
seeking in audio files. This bothered me greatly, which is why I'm
adding these additional options at all, and bothered with the previous
commit.
Fixes: #3056
Essentially, this lets video.c decide whether to consider a video track
cover art, instead of having the decoder wrapper use the lower level
sh_stream flag.
Some pain because of the dumb threading shit. Moving the code further
down to make some of it part of the lock should not change behavior,
although it could (framedrop nonsense).
This commit should not change actual behavior, and is only preparation
for the following commit.
on macOS 10.15 setting the activation policy behaves quite weirdly. the
call changes the current active App to a nameless process, which
probably also the reason that prevents the not focusing to work.
a workaround for that, is to refocus the previous active app.

brew update tries to update the java cask, which it tries to build from
source. this takes too long and leads to a timeout of the job. we can't
manually remove the java cask because of a bug in the too old brew cask
version and the old formula. we just remove the whole cask tap and call
it a day, since we don't need it anyway.
Back in the olden days, mpv's wayland backend was driven by the frame
callback. This had several issues and was removed in favor of the
current approach which allowed some advanced features (like
display-resample and presentation time) to actually work properly.
However as a consequence, it meant that mpv always rendered, even if the
surface was hidden. Wayland people consider this "wasteful" (and well
they aren't wrong). This commit aims to avoid wasteful rendering by
doing some additional checks in the swapchain. There's three main parts
to this.
1. Wayland EGL now uses an external swapchain (like the drm context).
Before we start a new frame, we check to see if we are waiting on a
callback from the compositor. If there is no wait, then go ahead and
proceed to render the frame, swap buffers, and then initiate
vo_wayland_wait_frame to poll (with a timeout) for the next potential
callback. If we are still waiting on callback from the compositor when
starting a new frame, then we simple skip rendering it entirely until
the surface comes back into view.
2. Wayland on vulkan has essentially the same approach although the
details are a little different. The ra_vk_ctx does not have support for
an external swapchain and although such a mechanism could theoretically
be added, it doesn't make much sense with libplacebo. Instead,
start_frame was added as a param and used to check for callback.
3. For wlshm, it's simply a matter of adding frame callback to it,
leveraging vo_wayland_wait_frame, and using the frame callback value to
whether or not to draw the image.
In the recent terminal commit, I "compressed" the read() error handling,
and messed it up. The return value could be -1 for other non-fatal
errors (such as EIO when trying to read while backgrounded), which
resulted in buf.len getting messed up.
Fixes: 602384348e
Nobody needs this anymore. If not too many people complain, we'll remove
this completely. Many already consider X11 and OpenGL legacy, so we
don't need TWO X11/OpenGL backends.
Due to Unix being legacy garbage, it's not possible to safely detect the
ESC key on terminal. The key sequences are ambiguous. The code for the
ESC key also starts the sequences for other special keys.
Until now, you needed to hit ESC twice for it to be recognized.
Attempt to handle this better by using a timeout to detect the key. If
ESC is in the input buffer, but nothing else arrived after a timeout,
assume it's the ESC key. I think this is the method vim uses. Currently,
the timeout is set at 100ms. This is hardcoded and cannot be changed.
It's possible that this causes problems on slow ssh connections or so.
I'm not sure what exactly happens if you manage to get ESC + another
normal key into the input buffer. If it's a known sequence, it will be
matched and interpreted as such. If not, it'll probably be discarded.
Previous commit fixes it for libswscale. The libzimg path has extra code
to copy by slice, but it still may access pixel groups using normal
memory accesses (for example, reading rgba pixel data via uint32_t), so
document a minimum alignment requirement per pixel format.
If the alignment is less than 16, certain libswscale code paths will
silently corrupt memory outside of the target buffer. This actually
affected the libmpv software rendering API (that was fun to debug).
Rather than passing this problem to the next API user, try to avoid it
within libmpv.
It's unclear which alignment libswscale requires for safe operation. I'm
picking 32 (one more than the observed safe value in the case I
experienced), because libavfilter mostly uses this value.
The way to work this around is slow: just make a full copy of the entire
input or output image. Possibly this could be optimized by using the
slice API, but that would be more effort, and would likely expose
further libswscale bugs. Hope that this is a rarely needed path.
The next commit will update the alignment requirement documentation
bits.
Pause can be changed during a file change, such as with for example
--reset-on-next-file=pause, or in hooks, or by being quick, and in this
case the AO's pause state was not updated correctly. mpctx->ao_chain is
only set if playback is fully initialized, while the AO itself in
mpctx->ao can be reused across files.
Fix this by always running set_pause_state() if the pause option is
changed. Could cause new bugs since running this used to be explicitly
avoided outside of the loaded state. The handling of time_frame is
potentially worrisome.
Regression due to recent audio refactor; before that, the AO didn't have
a separate/persistent pause state.
Fixes: #8079
Since b74c09efbf, audio-only files let you seek to arbitrary points
beyond the end of the file (but still displayed the time clamped to the
nominal file duration). This was confusing and just not wanted. The
reason is probably that the commit removed setting the audio PTS for
data before the seek target, so if you seek past the end of the file,
the audio PTS is never set. This in turn means the logic to determine
the current playback time has no PTS at all, and thus falls back to the
seek PTS.
This happened in the past for other reasons (like efe43d768f). I have
enough of this, so I'm just changing the code to clamp the seek
timestamp to a "known" range. Do this when seeking ends, because in the
fallback case, the playback time shouldn't be stuck at e.g. "end +
seek_argument". Also do it when initiating a new seek (mp_seek), because
if the previous seek hasn't finished yet, it shouldn't add them up and
allow it to go "out of range" either. The latter is especially relevant
for hr-seeks.
Doing this clamping is problematic because the duration is a possibly
invalid value from the demuxer, or just missing. Especially with
timestamp resets, fun sometimes happens, and in these situations it
might be better not to clamp.
One could argue you should just use the last audio timestamp returned by
the decoder or demuxer (even if that directly conflicts with --end), but
that sounds even more hairy.
In summary: what a dumb waste of time, what the fuck.
Add a property that returns whether the window is focused, currently
only for X11 and Wayland.
My use cause for this is having an equivalent of pause-when-minimize.lua
for tiling window managers: make mpv play only while it's in the current
workspace or is focused (I'm fine with either one but prefer focus).
On X I do this by observing display-names, which is empty when the
rectangles of the display and mpv don't intersect, but on Wayland its
value doesn't change when mpv leaves the current workspace (and the same
check doesn't work since the geometries still intersect).
This could later be made writable as requested in #6252.
Note that on Wayland se shouldn't consider an unactivated window with
keyboard input focused.
The wlroots compositors I tested set activated after changing the
keyboard focus, so if you set wl->focused only in
keyboard_handle_enter() and keyboard_handle_leave() to avoid adding the
"has_keyboard_input" member, focused isn't set to true when first
opening mpv until you focus another window and focus mpv again.
Conversely, if that order can't be assumed for all compositors, we
should toggle wl->focused when necessary in keyboard_handle_enter() and
keyboard_handle_leave() as well as in handle_toplevel_config().
--audio-stream-silence is a shitty feature compensating for awful
consumer garbage, that mutes PCM at first to check whether it's
compressed audio, using formats advocated and owned by malicious patent
troll companies (who spend more money on their lawyers than paying any
technicians), wrapped in a wasteful way to make it constant bitrate
using a standard whose text is not freely available, and only rude users
want it. This feature has been carelessly broken, because it's
complicated and stupid. What would Jesus do? If not getting an aneurysm,
or pushing over tables with expensive A/V receivers on top of them, he'd
probably fix the feature. So let's take inspiration from Jesus Christ
himself, and do something as dumb as wasting some of our limited
lifetime on this incredibly stupid fucking shit.
This is tricky, because state changes like end-of-audio are supposed to
be driven by the AO driver, while playing silence precludes this. But it
seems code paths for "untimed" AOs can be reused.
But there are still problems. For example, underruns will just happen
normally (and stop audio streaming), because we don't have a separate
heuristic to check whether the buffer is "low enough" (as a consequence
of a network stall, but before the audio output itself underruns).
Create a central function which pumps data through the filter. This also
might fix bogus use of the filter API on flushing. (The filter is just
used for convenience, but I guess the overall result is still simpler.)
The render API replaced the opengl_cb API over 2 years ago. Since then,
the opengl_cb API was emulated on top of the render API. While it would
probably be reasonable to emulate these APIs until they're removed in an
eventual libmpv 2.0 bump, I have some non-technical reasons to disable
the API now.
The API stubs remain; they're needed for formal ABI compatibility.
If you encode to e.g. an audio-only format, then video is disabled
automatically. This also takes care of the very cryptic error message.
It says "[vo/lavc] codec for video not found". Sort of true, but
obscures the real problem if it's e.g. an audio-only format.
I don't see the point of this. Not doing it may defer an error to later.
That's OK? For now, it seems better to reduce the encoding internal API.
If someone can demonstrate that this is needed, I might reimplement it
in a different way.
Since this is a messy and fragile mechanism, I want it logged (even if
it's somewhat in conflict with the verbose logging policy). On the other
hand, it's unconditionally logged on every playloop iteration. So add
some nonsense to log it only on progress.
Just for the redundant message. The function which is called here,
ao_drain(), does not care in which state it is called, and already
handled this gracefully.
AVFrame doesn't have public code for pool allocation, so mpv does it
manually. AVFrame allocation is very tricky, so we added a bug.
This crashed with libopus encoding, but not some other audio codecs,
because the libopus libavcodec wrapper accesses AVFrame.data. Most code
tries to avoid accessing AVFrame.data and uses AVFrame.extended_data,
because using the former would subtly corrupt memory on more than 8
channels. The fact that this problem manifested only now shows that most
AVFrame consuming FFmpeg code indeed uses extended_data for audio.
It is now the AO's responsibility to handle period size alignment. The
ao->period_size alignment field is unused as of the recent audio
refactor commit. Remove it.
It turns out that ao_alsa shows extremely inefficient behavior as a
consequence of the removal of period size aligned writes in the
mentioned refactor commit. This is because it could get into a state
where it repeatedly wrote single samples (as small as 1 sample), and
starved the rest of the player as a consequence. Too bad. Explicitly
align the size in ao_alsa. Other AOs, which need this, should do the
same.
One reason why it broke so badly with ao_alsa was that it retried the
write() even if all reported space could be written. So stop doing that
too. Retry the write only if we somehow wrote less.
I'm not sure about ao_pulse.
Unused, was terrible garbage. It was (or at least its implementation
was) always a make-shift solution, and just gross bullshit. It is unused
now, so delete it.
This replaces the two buffers (ao_chain.ao_buffer in the core, and
buffer_state.buffers in the AO) with a single queue. Instead of having a
byte based buffer, the queue is simply a list of audio frames, as output
by the decoder. This should make dataflow simpler and reduce copying.
It also attempts to simplify fill_audio_out_buffers(), the function I
always hated most, because it's full of subtle and buggy logic.
Unfortunately, I got assaulted by corner cases, dumb features (attempt
at seamless looping, really?), and other crap, so it got pretty
complicated again. fill_audio_out_buffers() is still full of subtle and
buggy logic. Maybe it got worse. On the other hand, maybe there really
is some progress. Who knows.
Originally, the data flow parts was meant to be in f_output_chain, but
due to tricky interactions with the playloop code, it's now in the dummy
filter in audio.c.
At least this improves the way the audio PTS is passed to the encoder in
encoding mode. Now it attempts to pass frames directly, along with the
pts, which should minimize timestamp problems. But to be honest, encoder
mode is one big kludge that shouldn't exist in this way.
This commit should be considered pre-alpha code. There are lots of bugs
still hiding.
Do not make resetting the "access" filters reset the queue itself. This
is more flexible, and will be used in a later commit.
Also, if the queue is not in the reset state while the input access
filter is reset, make it immediately request data again. This is more
consistent, because it'll enter the state it "should" be, rather when
the filter's process function is called at an (essentially) random point
in the future. This means the filter graph will resume work on its own
if the queue was not reset before filter reset.
This could affect the only current user of f_async_queue, the code for
the --vd-queue-enable/--ad-queue-enable feature in f_decoder_wrapper.
But it looks like this already uses it in a compatible way.
This is a kind of bad hack (with bad implementation) to paint over other
problems of the filter system. The main problem is that some filters
might be left with pending frames if the filter runner is "paused",
which we don't want. To be used in a later commit.
It's relevant in some obscure corner cases (EDL file that has a segment
without audio). Didn't test what's actually going on (is ad_lavc.c
behaving wrong? is libavcodec behaving wrong or in an unexpected way? is
lavc_process wrong?) and just patched it over with some bullshit, so the
fix might be too complicated, and could be reworked at some later point.
This sure is a real data flow fuckmess.
Allow mp_aframe_clip_timestamps() to discard a spdif frame if it's
entirely out of the timestamp range. Just a minor thing that might make
handling these dumb formats easier.
Transparent windows on X11/EGL/native Mesa GL didn't work for various
reasons. From what I remember, the current code did work with nvidia at
least. Mesa has made attempts to fix this, but they never really made it
in.
But it turns out you can make EGL/Mesa list the EGLConfigs that use X11
RGBA visuals, and context_x11egl.c contains code that explicitly selects
them if alpha is requested (see pick_xrgba_config()).
The reason EGL/Mesa did not list them (and thus breaking transparency)
is because we requested a EGL_ALPHA_SIZE != 0 if alpha is requested. But
the transparent EGLConfigs use EGL_ALPHA_SIZE == 0. That's because EGL
doesn't actually support the concept of transparent windows; the alpha
size parameter is something else (memory rendering without FBOs or
something, I don't care enough to look up the real reasons).
This still won't work on Wayland. Every EGL backend needs platform
specific code. (Good job, EGL, such an awesome platform independent
standard.)

Previously get_state() would keep setting the cork status
while paused, but it only does for that after underflows now.

Oversight in b0f0be7. The user_sbc value would update but not last_sbc
if no presentation events were received. This would result in an
incorrect sbc_passed value (in practice, this should always be 1 since,
as far I know, all wayland compositors are currently only capable of
double buffering). When bring the window back into view, it would result
in a single frame of very high vsync jitter. Although in most cases it
was imperceptible, rarely I was able to completely break playback (i.e.
constant mistimed/dropped frames). Fix this by simply incrementing
last_sbc by 1 if the window is hidden. The buffer swap call did still
occur. The user just didn't see it.
This reverts commit 41243e7c4f.
This fixes image format detection. FFmpeg has an utter called "image2",
which is designed to read patterns in filenames (so you can play
something like "%*.jpg" for all jpg files in the current directory).
"image2" is not what we want; it's just broken with custom I/O like
mpv uses it, and we don't want to "accidentally" interpret filenames
as pattern. That's why mpv blacklists it.
Unfortunately, "image2" is sometimes the format that FFmpeg's probe API
returns as best match. Thus demux_lavf fails to detect the file type,
and after some more futile attempts, we end up at demux_mf, which uses
detection by file extension. (Not sure why. I guess MPlayer did that,
and foudn that sufficient.) If the file extension is wrong (which
happens a lot because apparently the world is full of idiots who don't
manage to get the most simple things right), the image "loads", but
decoding obviously fails.
There's no easy way around this. The FFmpeg API has no mechanism to
exclude a specific format from probing (like image2, which breaks stuff
for us). Out of the 5 probe functions the API provides, none can probe
a specific format or include or exclude specific formats. The main
problem is that AVInputFormat.read_probe is a private symbol.
FFmpeg itself has no problem opening such files. It turns out that it
works, because even though image2 by itself uses detection by file
extension, it uses private API to further probe the exact format. It
explicitly excludes itself to prevent recursion.
But fortunately, that also means that it's impossible to get the image2
format if no filename is passed to the prober. (No filename, no file
extension.) Apparently we pass it in because it helps in corner cases.
Until almost 3 years ago, we passed the filename only when normal
probing already failed. Restore this by this revert. It makes
incorrectly named files work. The revert also makes the (apparently
forgotten) comment above the touched line of code true again.
Yes, quite possible that this breaks some mp3s again. You can't win
with FFmpeg. Thanks FFmpeg for making us fail at opening simple image
files and/or the most widely used file format for audio.
Why on earth did I ever bother with this dumb crap? If we do not have
any presentation statistics, just set the relevant vo_sync_info values
to -1 to disable it. It's much simpler than using mp deltas and trying
to keep up with mpv's clock. This also appears to fix audio/video
desynchronization if you start a video with the pause flag, move it out
of view, and then unpause it. Technically harmless since the video
wasn't even in view and putting back in view recovered it, but a quieter
terminal is better.
Well, whatever. Only results in an error message being printed, because
there is no other error reporting mechanism, and the general policy is
to keep trying with the rest of the data (i.e. not report EOF).
This can happen if a file contains headers only, or if decoding of all
data failed, and such. Interestingly, it also happened when doing "mpv
--loop emptyfile.png", because demux_mf still detects file formats by
file extension.
In this situation, the player burned a lot of CPU by restarting playback
after doing nothing. Although such "degenerate" behavior can't be
avoided in all situations (what if you loop a file with 1 audio
sample?), detecting this seems to make sense.
For now, this actually decrements the loop count by 1, and then errors
out with a warning. Works for --loop and --ab-loop, while
--loop-playlist already avoids this situation with an existing
mechanism.
Accepting ":" in addition to "," seems confusing and dumb. It only
causing problems when you want to pass a value that contains ":". Remove
support for ":", it is now treated like any other normal character. This
affects all options that are listed as "Key/value list" in the option
list.
It's possible that this breaks for someone who happened to use ":" as
separator. But this was undocumented, and never recommended. Originally,
the option treated many other characters in a special way, but this was
changed in commit a3d561f950. I'm, not sure why ":" was explicitly
included. Maybe because -the absurd -vf/--af syntax uses ":" as list
separator. But "," was always recommended and used in examples for
key/value options.

this is preparation for new backends. currently this is done via the
libmpv API but for future new new VOs not based on libmpv we need these
VOCTRL events.
remove the libmpv observer for the macOS specific options and use a
config cache + change callback for runtime changes. this is also a
preparation for new backends and generalises even more, since libmpv
functions can't and shouldn't be used in usual vo backends. for feature
parity the config cache is used.
move all backend independent code parts in their own folder and files,
to simplify adding new backends. the goal is to only extend one class
and add the backend dependent parts there. usually only the (un)init,
config and related parts need to be implemented per backend. furthermore
all needed windowing and related events are propagated and can be
overwritten. the other backend dependent part is usually the surface for
rendering, for example the opengl oder metal layer.
in the best case a new backend can be added with only a few hundred
lines.
The software rendering API makes libswscale directly write into supplied
user memory. As such, weird memory corruption bugs on non-optimal buffer
configurations are exposed to the user.
It was possible for sway to get incorrectly sized borders if you resized
the mpv window in a creative manner (e.g. open a video in a non-floating
mode, set window scale to 2, then float it and witness wrong border
sizes). This is possibly a sway bug (Plasma doesn't have these border
issues at least), but there's a reasonable workaround for this.
The reason for the incorrect border size is because it is possible for
mpv to ignore the width/height from the toplevel listener and set its
own size. This new size can differ from what sway/wlroots believes the
size is which is what causes the sever side decorations to be drawn on
incorrect dimensions.
A simple trick is to just explicitly commit the surface after a resize
is performed. This is only done if mpv is not fullscreened or maximized
since we always obey the compositor widths/heights in those cases.
Sending the commit signals the compositor of the new change in the
surface and thus sway/wlroots updates its internal coordinates
appropriately and borders are no longer broken.
This allows users to control whether full dialogue subtitles are displayed
with an audio track already in their preferred subtitle language.
Additionally, this improves handling for the forced flag, automatically
selecting between forced and unforced subtitle streams based on the user's
settings and the selected audio.
The original goal was to simplify all this logic to make it less fragile
and breaky. Unfortunately, that didn't exactly happen and things might
actually be more complicated in some ways (well in other ways it's
simplier). There's a lot of negotiation back and forth between the
client and the compositor regarding sizes. The client (aka mpv) can do a
resize on its own. But also the compositor can request its own resize
(which we should be nice and listen to of course). The older method had
a lot of breakfalls/edgecases that were gradually patched up as time
went on, but that approach is really fragile. This refactor should,
hopefully, be on a more solid foundation.
Don't call any of the xdg toplevel state changing functions
(fullscreen, maximized, etc.) directly. Use the toggle wrapper
functions. These signal that the state was changed which is later
handled in the toplevel listener.
Introduce a new vdparams variable that stores the actual dimensions of
the video. This does create some new (but neccesary) complexity.
wl->vdparams stores what the actual dimensions of the video are
(according to mpv). wl->window_size stores the last size of the window
(so it includes any manual resizes for instance). wl->geometry is the
actual size of the output that gets displayed on the screen.
Add support for reading a byte range from a stream via
the `slice://` protocol.
Syntax is `slice://start[-end]@URL` where end is a maximum
(read until end or eof).
Size suffixes support in `m_option` is reused so they can
be used with start/end.
This can be very useful with e.g. large MPEGTS streams with
corruption or time-stamp jumps or other issues in them.

We've had some serious issues with GNOME in the past, but since then
their compositor has undergone some major internal improvements. The
most severe one [1], random vsync spikes and mistimed frames, can no
longer be reproduced by the original author of the issue. There are some
minor UI-related things (lack of window decorations for instance since
there is no xdg-decoration support), but users don't seem to complain
about that too much and they aren't revelant to playback.
3.38 isn't out quite yet, but that should also fix playback issues when
on a multimonitor setup (the fix is in the master branch at the moment).
In terms of playback, the only real concerning issue is the lack of idle
inhibit so a warning is still displayed. But GNOME has their own
workaround that users can use for that so if anyone happens to complain,
we can just point them to that.

When using presentation time, we have to be sure to update the ust when
no presentation events are received to make sure playback is still
smooth and in sync. Part of the recent presentation time refactor was to
use the presentation discarded event to signal that the window is
hidden. Evidently, this doesn't work the same everywhere for whatever
reason (drivers?? hardware??) and at least one user experienced issues
with playback getting out of sync since (presumably) the discarded event
didn't occur when hiding the window. Instead, let's just go back to the
old way of checking if the last_ust is equal to the ust value of the
last member in the wayland sync queue. Fixes#8010.
The motivation for this change was a segfault caused by e107342 which
has complicated reasons for occuring (i.e. I'm not 100% sure but I think
it is a really weird race). The major part of this commit is moving the
initialization of presentation listener to the frame_callback function.
Calling it in swap_buffers worked fine but in practice it meant a lot of
meaningless function calls if a window was hidden (the presentation
would just be immediately discarded). By calling it in frame_callback,
we ensure the listener is only created when it is possible to receive a
presentation event.
Of course calling the presentation listener in feedback_presented or
feedback_discarded was considered, but ultimately these events are too
slow. Receiving the ust/msc/sbc triplet here and then passing it to mpv
results in higher vsync judder since there is (likely) not enough time
before the next pageflip. By design, the frame callback is meant to give
us as much time as possible before the next repaint so calling it here
is probably optimal.
Additionally, we can make better use of the feedback_discarded event.
The wp_presentation_feedback should not be destroyed here. It will be
taken care of either when we get feedback again or when the player
quits. Instead what we can do is set a bool that tells wayland_sync_swap
to update itself based on mp_time delta. In practice, the result is not
any different than before, but it should be more understandable what is
going on now.
Of course, the segfault mentioned at the beginning is fixed with this as
well.
lua/js utils.get_env_list() uses `environ' which was ANSI, thus
it broke any unicode names/values.
mpv already has an internal utf8_environ for win32, but it's used
only at the getenv(..) wrapper and not exposed in itself, and also it
has lazy initialization - on first getenv() call.
Now `environ' maps to a function which ensures initialization while
keeping it an l-value (like posix expects).
The cost of this fuglyness is that files should include osdep/io.h
(which now declares environ as extern) rather than declaring it
themselves, or else the build will break on mingw.
This was a vague idea how to handle passing byte arrays from Lua to the
mpv command interface in a somewhat reasonable way. The idea was
cancelled, but leave the Lua part of it, since it might get useful
later, and prevents passing (and silently cutting off) such byte
strings.
Barely tested, let's say not tested at all.
Make it possible to feed a string to stdin of a subprocess. Out of
laziness, it can't be an arbitrary byte string. (Would require adding an
option type that takes in a Lua byte string.)
Do not set stdin of a subprocess to fd 0 (i.e. mpv's stdin) anymore,
because it makes things more consistent. Enabling stdin didn't make too
much sense in the first place, so this behavior change seems
justifiable.
win32 support missing.
Fixes: #8003
Such files violate the specification. Unfortunately, I could not test
whether it really works correctly, since I don't have a sample at hand
that is not broken in this regard.
Nothing major but it's technically possible for the
wp_presentation_feedback struct to still be allocated when quitting the
player. Just destroy it if it exists like all of the other wayland
objects.
In a playlist of videos with different sizes, going to the next video
would not properly resize the window. This actually broke way back in
7170910 (oops), but somehow nobody ever complained. The fix is simple.
If a window isn't maximized, be sure to set the window geometry again.
Just some small changes when creating the xdg_surface. Don't set the
toplevel title (or app id) in create_xdg_surface anymore because it's
entirely pointless. Also make it possible for create_xdg_surface to
return something other than 0 so the error checking is somewhat
meaningful. It's not really clear if these xdg functions can even fail
in the first place (perhaps some weird proxy marshalling crap could
possibly go wrong somehow), but it can't hurt. Note that all app id
stuff has been removed (temporarily) in this commit. See the next commit
which adds it back in.
The subtitle list is returned in randomized order, because a table (i.e.
JSON object) is used. To make the order stable across repeated
invocations, sort it by language.
This was incorrect, and grossly misleading. It created the impression
that the buffer is passed to mpv_render_context_create(), instead of
mpv_render_context__render().
(The recommendation is to add the document to the project git root, but
I'm against dumping such things into git. I'd rather replace the
Copyright full text files with links and move contribute.md to the wiki
than add the CCoC text as a file.)
Seems like this is requested all the time.
It seems libass allows out of range values, but does allows the subtitle
to go out of the screen at the bottom (only when moving it to the top
it's "clamped"). Too bad, don't do that then. The bitmap sub rendering
code on the other hand is under our control, and will not move a
subtitle out of the screen.
Fixes: #7986
Options like --sub-ass-force-style and others could not be changed at
runtime (the changes didn't take any effect). Fix this by using the
brutal approach, and completely reinit the subtitle state when this
happens. Maybe a bit clunky, but for now I'd rather not put more effort
into this.
Fixes: #7689
Requested. Should be good for simple use cases. "sub2" is technically
inconsistent (since the option is called --secondary-sid), but fuck the
consistent name.
The same was done to matroska.py before, so at least it's consistent.
Doesn't matter for waf, because it imports this script (rather than
executing it).
This sets the activeCodePage property in the manifest, which forces the
ANSI code page to be UTF-8 in Windows 10 1903 and up. It shouldn't make
a difference for mpv itself, since mpv already uses the wide-char APIs
for most functions, however some of mpv's dependencies, such as Lua,
rely on the ANSI codepage. Hence this change enables support for Unicode
file names in Lua's I/O library.
Thanks @avih for finding this property.

FFmpeg expects those fields to be set on the AVFrame when
encoding audio, not doing so will cause the avcodec_send_frame
call to return EINVAL (at least in recent builds).
Uses the mechanism introduced in the previous commit. The hope was to
make auto-profiles easier to use, and to get rid of the need for
manually created inverse profiles. Not sure if the end result is useful.
Make it possible to restore from profiles by backing up the option
values before profile application. This is sort of like unapplying a
profile. Since there might be multiple ways to do this, a profile needs
to explicitly provide the "profile-restore" option, which specifies how
exactly this should be done.
This is a big mess. There is not natural way to do this. Profile
application is "destructive" and simply changes the values of the
options. Maybe one could argue that the option system should have
hierarchical "overlays" of profiles instead, where unset options will
use the value of the lower profiles. Options set interactively by the
user would be the top profile. Default values would be in the lowest
profile. You could unapply a profile by simply removing it from this
overlay stack.
But uh, let's not, so here's something stupid. It reuses some code used
for file local options to reduce code size. At least the overlay idea
would still be possible in theory, and could be added as another
profile-restore mode.
This is used by the following commit.
The callback now gets an object argument with defer/cont functions.
Like the lua code, the behavior is that each hook event allows at
most one continue, but nothing enforces the order of continuations
if more hook events arrive before prior ones were continued - which
is possible now with the defer option, but wasn't possible before
(continuation was synchronous from the hook event handler).
The property observation mechanism is fairly asynchronous to the player
core, and Lua scripts also are (they run in a separate thread). This may
sometimes lead to profiles being applied when it's too load.
For example, you may want to change network options depending on the
input URL - but most of these options would have to be set before the
HTTP access is made. But it could happen that the profile, and thus the
option, was applied at an slightly but arbitrary later time.
This is generally not fixable. But for the most important use-cases,
such as applying changes before media opening or playback
initialization, we can use some of the defined hooks.
Hooks make it synchronous again, by allowing API users (such as scripts)
to block the core because it continues with loading.
For this we simply don't continue a given hook, until we receive an idle
event, and have applied all changes. The idle event is in general used
to wait for property change notifications to settle down. Some of this
relies on the subtle ways guarantees are (maybe) given. See commit
ba70b150fb for the messy details. I'm not quite sure whether it
actually works, because I can't be bothered to read and understand my
bullshit from half a year ago. Should provide at least some improvement,
though.
This can now opt to not continue a hook after the hook callback returns.
This makes it easier for scripts, and may make it unnecessary to run
reentrant event loops etc. for scripts that want to wait before
continuing while still running the event loop.
This is taken from a somewhat older proof-of-concept script. The basic
idea, and most of the implementation, is still the same. The way the
profiles are actually defined changed.
I still feel bad about this being a Lua script, and running user
expressions as Lua code in a vaguely defined environment, but I guess as
far as balance of effort/maintenance/results goes, this is fine.
It's a bit bloated (the Lua scripting state is at least 150KB or so in
total), so in order to enable this by default, I decided it should
unload itself by default if no auto-profiles are used. (And currently,
it does not actually rescan the profile list if a new config file is
loaded some time later, so the script would do nothing anyway if no auto
profiles were defined.)
This still requires defining inverse profiles for "unapplying" a
profile. Also this is still somewhat racy. Both will probably be
alleviated to some degree in the future.
Sway 1.5 started sending more pointer motion events to mpv which broke
the autohiding behavior. The cursor would appear again if you
fullscreened. Sway had a good reason to do this because certain
applications had inconsistencies between hardware cursor and software
cursor without rebasing on state changes[1]. So mpv needs to take this
special case into consideration.
Initially, simply checking mouse coordinates for changes was considered,
but this doesn't work. All coordinates are surface-local in wayland so
something can appear to move in the local coordinate space but not
globally. You're not allowed to know global mouse coordinates in
wayland, and we don't care about local coordinate changes in mpv so this
approach isn't viable.
Instead, let's just keep track of a local state change. If the toplevel
surface changes in some way (fullscreen, maximized, etc.), then just set
a bool that lets us ignore the mp_input_set_mouse_pos function. This
keeps the cursor from appearing simply because the state was changed
(i.e. fullscreening). For compositors that don't send pointer motion
events on a state change, this does technically mean that the initial
mp_input_set_mouse_pos is never set. In practice, this isn't a
noticeable difference though because moving a mouse generates a ton of
motion events so you'll immediately see it on the second motion event.

wl_display_dispatch is dangerous because it will block forever if the
event queue is empty. Any direct calls to this function should just be
replaced with wl_display_dispatch_pending which accomplishes the same
thing for mpv's purposes without any chance of blocking.
The other potential trap is wl_display_roundtrip. It can internally call
wl_display_dispatch which in certain circumstances could potentially
block. There are cases where we need the server to finish processing
client requests before doing anything else so this can not be cleanly
avoided. The dangerous call is the usage of wl_display_roundtrip in
vo_wayland_wait_frame. In the majority of cases, this shouldn't be a
problem because the previous wl_display_read_events should always queue
up some events on the fd for wl_display_roundtrip to send. However, the
compositor could potentially send us an error in the display queue that
could lead to bad behavior when wl_display_roundtrip is called.
The wl_display_roundtrip can't be removed because we are relying on its
semi-blocking capabilities, but the logic can be slightly adjusted to be
safer. The obvious thing to do is to make sure we check the pollfd for
any errors. If one is returned, then we call wl_display_cancel_read and
try again. The less obvious trick is to call wl_display_dispatch_pending
and move wl_display_roundtrip outside of the blocking + timeout loop.
This change has some subtle but important differences. Previously,
vo_wayland_wait_frame would read an event and wait on the server to
process it one-by-one. With this change, the events are dispatched as
soon as possible to the server and then we wait on all of those
(potentially multiple) events to be processed after we have either
received frame callback or the loop times out.
After that is done, we can then check for if there are any errors on the
display. If it's all clear, we can run wl_display_roundtrip without any
worries. If some error happens, then don't execute the function at all.
the problem here is that with time, and because the macOS VMs don't get
updated, the homebrew update is getting longer since more and more
changes have to be pulled. to prevent that, we cache the homebrew
installation folder after the update. that way we don't have to update
several months worth of updates every build. for the legacy build we
have to check put master again to actually cache the newest homebrew
version.
additionally to that, we also do the same as on the legacy build, with
the addition of not removing all installed formulas but only the ones
we don't need. so we don't need to reinstall those.
just remove all pre installed formulas, since we don't need the majority
of it. after that install what we need. this also fixes the brew update
of those formulas where the source links were broken like popt.
this also helps when the build times out due to building some formulas
from source that are not dependencies we need.
Previously, the compositor was signaled that a drag-and-drop ended with
wl_data_offer_finish in check_dnd_fd. This is, however, erroneous
because it is outside of the data_device_listener and in some cases
caused errors with certain compositors. check_dnd_fd itself does not
need to know or care about anything that happens in wayland. It just
needs to read data from an fd. The simple fix is to just always signal
the end of a drag-and-drop in data_device_handle_drop. check_dnd_fd can
free memory and close the fd later, but it should not talk to the
compositor. Fixes#7954.
The read of the wayland display fd in vo_wayland_wait_events was
incorrect and technically vulnerable to race conditions. The correct
usage as per the client api is to use wl_display_prepare_read as well as
wl_display_read_events.
scaletempo2 is a new audio filter for playing back
audio at modified speed and is based on chromium
commit 51ed77e3f37a9a9b80d6d0a8259e84a8ca635259.
It sounds subjectively better than the existing
implementions scaletempo and rubberband.
This fixes the "run" and "subprocess" commands on Windows, including
youtube-dl support.
Unix-like FD inheritance is emulated on Windows by using an undocumented
data structure[1] that gets passed to the newly created process in
STARTUPINFO.lpReserved2. It consists of two sparse arrays listing the
HANDLE and internal CRT flags corresponding to each FD. This structure
is used and understood primarily by MSVCRT, but there are other runtimes
and frameworks that can write it, like libuv.
The code for creating asynchronous "anonymous" pipes in Windows has been
enhanced and moved into windows_utils.c. This is mainly an artifact of
an unfinished future change to support anonymous IPC clients in Windows.
Right now, it's still only used in subprocess-win.c
[1]: https://www.catch22.net/tuts/undocumented-createprocess
Sharing a process sure is hard in POSIX.
The rationale is that you'd have to handle EINTR on every single
blocking syscall. stream_file.c does not seem to handle it on read()
calls.
It appears that on most modern systems, this can happen only if you call
sigaction(), and incompetently forget to add SA_RESTART. signal()
usually adds it.
Add env and detach arguments. This means the command.c code must use the
"new" mp_subprocess2(). So also take this as an opportunity to clean up.
win32 support gets broken by it, because it never made the switch to the
newer function.
The new detach parameter makes the "run" command fully redundant, but I
guess we'll keep it for simplicity. But change its implementation to use
mp_subprocess2() (couldn't do this earlier, because win32).
Privately, I'm going to use the "env" argument to add a key binding that
starts a shell with a FILE environment variable set to the currently
playing file, so this is very useful to me.
Note: breaks windows, so for example youtube-dl on windows will not work
anymore. mp_subprocess2() has to be implemented. The old functions are
gone, and subprocess-win.c is not built anymore. It will probably work
on Cygwin.
Rather than after tone-mapping. This prevents overflow when the
pre-tonemapped signal contains inputs exceeding sig_peak. I also
realized that with this clipping in place, post-clipping no longer needs
to be done, so this isn't even particularly slower.
The only two exceptions to the rule are "clip" and "linear", which
relied on the post-clipping to do their tone mapping properly.
Fixes#7929
This normally gets printed by libplacebo itself when initializing the
context, but due to the way our code is structured (for convenience) we
don't have the log hook enabled by the time this function call is
relevant. So instead just print it manually as an easier work-around
than restructuring the code.
This probably makes it much faster (I wouldn't know, I didn't run any
benchmarks ). Seems to work as well (although I'm not sure, it's not
like I'd perform rigorous tests).
The scale_zimg test seems to mysteriously treat color in fully
transparent alpha differently, which makes no sense, and isn't visible
(but makes the test fail). I can't be bothered with investigating this
more. What do you do with failing tests? Correct, you disable them. Or
rather, you disable whatever appears to cause them to fail, which is the
threading in this case.
This change follows mostly the tile_example.cpp. The slice size uses a
minimum of 64, which was suggested by the zimg author. Some of this
commit is a bit inelegant and weird, such as recomputing the scale
factor for every slice, or the way slice_h is managed. Too lazy to make
this more elegant.
zimg git had a regressio around active_region (which is needed by the
slicing), which was fixed in commit 83071706b2e6bc634. Apparently, the
bug was never released, so just add a warning to the manpage.
The intention is to add slice-threading to the wrapper. For that
purpose, move all zimg related state to a new struct mp_zimg_state.
There is now an array of instances of this struct. The intention is to
have one instance for each thread. As of this commit, this is hardcoded
to 1 thread; the following commit extends this.
libass recently switched the default from 1 to 0 for compatibility
with ASS scripts that rely on the historical/VSFilter default of 0.
libass does attempt to detect and avoid breaking scripts that rely
on the historic libass-only default of 1, but it doesn't cover tracks
created directly through the API, so set the header explicitly.

It turns out that the AMD driver doesn't bother to set the size
field in the descriptor for an exported VA surface. I guess they
assume the caller can always use lseek() and don't bother. So, we
need to use lseek() in these situations.

Guarded this behind PL_API_VER >= 88 to prevent it from exploding on
older libplacebo versions, where vaapi support does not yet work
properly on AMD due to lack of DRM modifiers.
When get_state() corks the stream after an underrun happens
priv->playing is incorrectly reset to true, which can cause the
player to miss the underrun entirely. Stop resetting priv->playing
during corking (but not uncorking) to fix this.
The underflow callback introduced in d27ad96 can be called
when the buffer is still full, causing playback to never
resume afterwards since get_state() reports free_samples == 0.
Fix this by fully resetting on underrun, which flushes
the stream and ensures free buffer space.
fixes#7874
we properly set the unfs window size on live resize end. due to a race
condition in the fullscreen events, which is also a live resize, the
unfs window size is incorrectly set to a fullscreen size. this happens
when the end fs screen event triggers before the end of live resize one.
this just adds a second condition to not be un fullscreen when updating
the unfs window size.
Mess this into the --geometry option, because I like to be
irresponsible. I considered adding a separate option, but at least this
allows me to defer the question how the hell this should work as
property (geometry simply and inherently does not).
Tested on IceWM only. Option equality test and string output not tested.
Probably did not cause any practical problems, but it sure seems
unclean. sws_utils users might also rely on these fields being exactly
the same as the actual input/output. It's better to avoid this.
I'm tired of dealing with this frequent spawning of xdg-screensaver when
debugging and what not. xdg-screensaver was never a serious tool anyway,
it's more like some self-deprecating joke by FDO folks.
This will affect X11 on GNOME and other DEs. I'm singling out GNOME
though, because they are the ones actively sabotaging any sane
technical solutions and community cooperation.
I have been accused of taking it out on innocent GNOME users, while none
of this will reach GNOME developers. Of course that is not the
intention.
This can be used to make vo_libmpv render video to a memory buffer. It
only adds a new backend API that takes memory surfaces. All the render
API (such as frame rendering control and so on) is reused.
I'm not quite convinced of the usefulness of this, and until now I
always resisted providing something like this. It only seems to
facilitate inefficient implementation. But whatever.
Unfortunately, this duplicates the software rendering glue code yet
again (like it exists in vo_x11, vo_wlshm, vo_drm, and probably more).
But in theory, these could reuse this backend in the future, just like
vo_gpu could reuse the render_gl API.
Fixes: #7852
libplacebo exposes this feature already, because this particular type of
bug is unusually common in practice. Simply make use of it, by exposing
it as an option.
Could probably also bump the libplacebo minimum version to get rid of
the #if, but that would break debian oldoldstable or something.
Fixes#7867.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
XDG is stupid, so change back to the standard behavior. Unfortunately,
most users will now have the XDG one, so we will still need to load
this. (This is exactly the same problem as when XDG support was
introduced, just the other way around).
This should not affect any normal users. Hopefully I tested this well
enough; my intention is not to torment miserable XDG fans; they can keep
using their config dir if they want it.
This changes behavior in two cases:
- new users (now creates ~/.mpv/ instead of ~/.config/mpv/)
- users which have both directories
The latter case will behave subtly or obviously different, not sure.
Just fix your shit.
Extend the manpage with all the messy details, as far as I could reverse
engineer them from the code.
De-emphasize it, since a user should usually not use it. This _could_ be
used to make the cache seekable with --cache=no, but it's better and
more intuitive to use --cache=yes. As such, the only use of this is for
debugging. I'm not quite sure if this should be removed entirely, but I
still see some value in it (for example if you want the cache lookahead,
but you're using a stream where cache seeking is somehow broken).
Using mediump float on GLES causes problems with kernel resampling,
PQ HDR, and possibly others. The issues are fixed by using highp,
which is available when GL_FRAGMENT_PRECISION_HIGH is defined.
--dscale= and --*scale-window= (i.e. an empty string) are respectively
valid settings for their options (and, in fact, the defaults).
This fixes the bug that it was impossible to reset e.g. tscale-window
back to the default "unset" setting after setting it once.
Credit goes to @CounterPillow for locating the cause of this bug.
For testing in VMs I guess?
This features a very broken hack that probably works. Though I didn't
test the packed format case. Again, the mismatch is essentially due to
big endian byte addresses decreasing as bit addresses increase, so you
can't represent a bit position in a byte stream with a single address,
which the mpv metadata does.
OSD is broken because repack.c doesn't support big endian. You'll have
to live with it.
The recent changes to the image format metadata broke big endian, and
that was intentional. Some things are inherent to little endian (like
the idea to coalesce bit and byte offsets into a single bit offset), and
they don't be fixed. But some obvious things can be fixed, such as
marking LE vs. BE formats the right way around on BE hosts.
The metadata is formally still in LE, except that if the LE/BE flag
matches the host endian, the host endian can be used when accessing
packed formats with bit shifts, or when computing byte aligned component
byte offsets. The former may work because formats with LE/BE variants
use the same bit offsets after byte swapping, the latter may work
because little endian is the natural concept for addressing memory. But
it will "subtly" fail to do the right thing in some cases, and code
using this can't know, so have fun.
Many things are broken, but this makes e.g. vo_gpu mostly work.
My general opinion about BE computers is that you should get a better
computer, you can get one for free from any garbage dump.
IMGFMT_RGB30 was added first; FFmpeg added AV_PIX_FMT_X2RGB10 later.
This is exactly the same, so treat them as such. For some reason,
libswscale still seems to output incompatible data - not sure what this
is about, but I'm not going to debug it.
Instead of applying this only to "regular" formats, do it with all
formats.
For some reason, some repackers still have their own endian code. These
could probably be removed, but whatever.
This change attempts to fix detection of how endian swapping is to be
performed. Details can be found in the code comments.
It should not change anything, other than fixing handling of the
X2RGB10BE ffmpeg pixel format. This format was detected incorrectly, and
the component location metadata was discarded due to an internal
consistency check. With this commit, it is handled correctly. At first I
thought the X2RGB10BE ffmpeg pixdesc metadata was wrong, but it appears
to be correct. The problem with this format is that it's the first
packed RGB format that requires bit shift to access, and where the
endian word size is larger than the (rounded up) component size, all
while pixdesc would "require" you to perform 3 memory accesses (instead
of 1), and the code tries to reverse this.
It appears that trying to use the pixdesc metadata is much, much more
work than just duplicating it in a saner form. To be fair, most problems
are with big endian, and the mpv internal format does not care much
about endian _hosts_.
The pull mode APIs were previously required to have thread-safe
ao_controls. However, locks were added in b83bdd1 for parity with push
mode. This introduced deadlocks in ao_wasapi.
Instead, only lock ao_control for the push mode APIs.

See also #7832, #7811. We'll wait for feedback to see if those should
also be closed.
For cases in which the requirements of the GPU API prevent directly
uploading a texture with a given stride, we need to fix the stride
manually in host memory. This incurs an extra memcpy, but there's not
much we can do about it. (Even in `ra_gl` land, the driver will just
hide this memcpy from the user)
Note: This code could be done better. It could only copy as many texels
as needed, and it could pick a stride that's a multiple of
`gpu->limits.align_tex_xfer_stride` for better performance. Patches
welcome (tm)

Implementation copy/pasted from:
https://code.videolan.org/videolan/libplacebo/-/commit/f793fc0480f
This brings mpv's tone mapping more in line with industry standard
practices, for a hopefully more consistent result across the board.
Note that we ignore the black point adjustment of the tone mapping
entirely. In theory we could revisit this, if we ever make black point
compensation part of the mpv rendering pipeline.
This standard says we should use a value of 203 nits instead of 100 for
mapping between SDR and HDR.
Code copied from https://code.videolan.org/videolan/libplacebo/-/commit/9d9164773
In particular, that commit also includes a test case to make sure the
implementation doesn't break roundtrips.
Relevant to #4248 and #7357.
glslang accepted this, perhaps erronneously, but mesa does not. It seems
to be incorrect. A caveat is that this means *all* SSBOs are now
coherent, but since we only use SSBOs for peak detection, that's a
non-issue. (And besides, marking something as coherent when we don't
perform any synchronization commands on it should be a no-op anyway)

Commit fcf0b80dc9 fixed this the first time. Commit 85576f31a9
"accidentally" removed this code again. The commit message justifying
the removal is correct, except it doesn't take other side-effects of the
state machine into account. I obviously didn't remember what exactly
this was about. So add a comment explaining it this time.
Just apply it again; the thing the latter commit fixed still works.
Fixes: #7819
AOs which use the "push" API must set this field now. Actually, this was
sort of always required, but happened to work anyway. The future
intention is to use device_buffer as the pre-buffer amount, which has to
be available right before audio playback is started. "Pull" AOs really
need this too conceptually, just that the API is underspecified.
From what I can see, only ao_null did not do this yet.
Previously, device_buffer defaulted to 0 on pulse. This meant that
commit baa7b5c would always wait with a timeout of 0, leading to
high CPU usage for PulseAudio users.
By setting device_buffer to the number of samples per channel that
PulseAudio sets as its target, this commit fixes this behaviour.
since the title bar catches the mouse up and down events, the underlying
events view doesn't reset the isMoving state and no mouse movements are
signalled to the core. now we also reset the state in mouse up events
on the title bar.
Fixes#7807
The "screenshot window" command (ctrl+s by default) somehow broke video
colors with --gpu-api=vulkan --profile=gpu-hq when playback was paused.
I don't know the cause, but the rest of the code seems to imply
gl_video_reset_surfaces() needs to be called manually to flush some
caches, and it fixes the issue, so I assume there's no great mystery
here.
Commit 07b0c18 introduced some build breakages. Some breakages

The playback thread may obviously still fill the AO'S entire audio
buffer, which means it unset p->draining, which makes no sense and broke
ao_drain(). So just don't unset it here.
Not sure if this really fixes this, it was hard to reproduce. Regression
due to the recent changes. There are probably many more bugs like this.
Stupid asynchronous nightmare state machine. Give me a language that
supports formal verification (in presence of concurrency) or something.
I feel like this makes slightly more sense. At least it doesn't include
the potentially arbitrary constant latency that is generally included in
the delay value. Also, the buffer status doesn't matter - either we've
filled the entire buffer (then we can wait this long), or there's not
enough data anyway (then the core will wake up the thread if new data is
available).
But ultimately, we have to guess, unless the AO does notify us with
ao_wakeup_playthread().
Draining may now wait for no reason up to 1/4th of the total buffer
time. Shouldn't be a disimprovement in practice.
It's conceivable that ao->driver->reset() will make the audio API wait
for ao_read_data() (i.e. its audio callback) to return. Since we
recently moved the reset() call inside the same lock that ao_read_data()
acquires, this could deadlock. Whether this really happens depends on
how exactly the AO behaves. For example, ao_wasapi does not have this
problem. "Push" AOs are not affected either.
Fix by moving it outside of the lock. Assume ao->driver->start() will
not have this problem.
Could affect ao_sdl, ao_coreaudio (and similar rotten fruit AOs). I'm
unsure whether anyone experienced the problem in practice.
Instead of the relatively subtle underflow handling, simply signal
whether the stream is in a playing state. Should make it more robust.
Should affect ao_alsa and ao_pulse only (and ao_openal, but it's
broken).
For ao_pulse, I'm just guessing. How the hell do you query whether a
stream is playing? Who knows. Seems to work, judging from very
superficial testing.
Just a detail. If wrong (not unlikely because I'm just guessing my own
messy state machine), this will make the player freeze due to waiting
for something that never happens. Enjoy.
The feeder thread basically woke up the core and itself too often, and
caused some CPU overhead. This was caused by the recent buffer.c
changes.
For one, do not let ao_read_data() wake up the core, and instead rely on
the feeder thread's own buffer management. This is a bit strange, since
the change intended to unify the buffer management, but being more
consequent about it is better deferred to later, when the buffer
management changes again anyway. And also, the "more" condition in the
feeder thread seems outdated, or at least what made it make sense has
been destroyed, so do something that may or may not be better. In any
case, I'm still not getting underruns with ao_alsa, but the wakeup
hammering is gone.
Commit 6a13954d67 lowered the frequency of wakeups with this
condition. But it seems it sometimes the audio sync mode really should
get the wakeup before the frame is rendered. Normally, vo_thread is
supposed to perform this wakeup. Now the wakeup frequency is twice of
what should be needed - whatever, maybe it can be fixed properly once or
if timing is moved to the VO entirely in the future.
Fixes: #7777 (probably, untested)
This affects "pull" AOs only: ao_alsa, ao_pulse, ao_openal, ao_pcm,
ao_lavc. There are changes to the other AOs too, but that's only about
renaming ao_driver.resume to ao_driver.start.
ao_openal is broken because I didn't manage to fix it, so it exits with
an error message. If you want it, why don't _you_ put effort into it? I
see no reason to waste my own precious lifetime over this (I realize the
irony).
ao_alsa loses the poll() mechanism, but it was mostly broken and didn't
really do what it was supposed to. There doesn't seem to be anything in
the ALSA API to watch the playback status without polling (unless you
want to use raw UNIX signals).
No idea if ao_pulse is correct, or whether it's subtly broken now. There
is no documentation, so I can't tell what is correct, without reverse
engineering the whole project. I recommend using ALSA.
This was supposed to be just a simple fix, but somehow it expanded scope
like a train wreck. Very high chance of regressions, but probably only
for the AOs listed above. The rest you can figure out from reading the
diff.
wasapi/coreaudio/sdl were affected, alsa/pusle were not.
The confusion here was that resume() has different meaning with pull and
push AOs.

This should make --term-title work in Windows 8.1 and below.
OSC sequences are defined in ECMA-48. The 'Change Window Title' command,
as far as I can tell, is a de-facto standard defined by xterm[1]. In
either case, this code is probably still not standards-compliant.
This also changes mp_write_console_ansi to convert to UTF-16 before
parsing control sequences, because that made it easier to pass the OSC
param to SetConsoleTitleW. I think it's also more correct to do it this
way, even though it doesn't really matter much for our limited terminal
parsing. As a side-effect of this, mp_write_console_ansi no longer
mutates its argument.

Regression since the recent refactor. How did nobody notice?
This happened because the push code now calls the function for the pull
code. Both the former and latter apply the volume, so oops.
The recent change to the common code removed all calls to ->drain. It's
currently emulated via a timed sleep and polling ao_eof_reached(). That
is actually fallback code for AOs which lacked draining. I could just
readd the drain call, but it was a bad idea anyway. My plan to handle
this better is to require the AO to signal a underrun, even if
AOPLAY_FINAL_CHUNK is not set. Also reinstate not possibly waiting for
ao_lavc.c. ao_pcm.c did not have anything to handle this; whatever.
This simply printf()s a concatenation of the provided string and the
relevant escape sequences. No idea what exactly defines this escape
sequence (is it just a xterm thing that is now supported relatively
widely?), and this simply uses information provided on the linked github
issue.
Not much of an advantage over --term-status-msg, though at least this
can have a lower update frequency. Also I may consider setting a default
value, and then it shouldn't conflict with the status message.
Fixes: #1725
This is preparation to further cleanups (and eventually actual
improvements) of the audio output code.
AOs are split into two classes: pull and push. Pull AOs let an audio
callback of the native audio API read from a ring buffer. Push AOs
expose a function that works similar to write(), and for which we start
a "feeder" thread. It seems making this split was beneficial, because of
the different data flow, and emulating the one or other in the AOs
directly would have created code duplication (all the "pull" AOs had
their own ring buffer implementation before it was cleaned up).
Unfortunately, both types had completely separate implementations (in
pull.c and push.c). The idea was that little can be shared anyway. But
that's very annoying now, because I want to change the API between AO
and player.
This commit attempts to merge them. I've moved everything from push.c to
pull.c, the trivial entrypoints from ao.c to pull.c, and attempted to
reconcile the differences. It's a mess, but at least there's only one
ring buffer within the AO code now. Everything should work mostly the
same. Pull AOs now always copy the audio data under a lock; before this
commit, all ring buffer access was lock-free (except for the decoder
wakeup callback, which acquired a mutex). In theory, this is "bad", and
people obsessed with lock-free stuff will hate me, but in practice
probably won't matter. The planned change will probably remove this
copying-under-lock again, but who knows when this will happen.
One change for the push AOs now makes it drop audio, where before only a
warning was logged. This is only in case of AOs or drivers which exhibit
unexpected (and now unsupported) behavior.
This is a risky change. Although it's completely trivial conceptually,
there are too many special cases. In addition, I barely tested it, and
I've messed with it in a half-motivated state over a longer time, barely
making any progress, and finishing it under a rush when I already should
have been asleep. Most things seem to work, and I made superficial tests
with alsa, sdl, and encode mode. This should cover most things, but
there are a lot of tricky things that received no coverage. All this
text means you should be prepared to roll back to an older commit and
report your problem.
When the window is mapped, some ICCCM WM_HINTS are set.
The input field is set to true and state is set to NormalState.
To quote the spec, "The input field is used to communicate to the window
manager the input focus model used by the client" and "[c]lients with
the Passive and Locally Active models should set the input flag to True".
mpv falls under the Passive Input model, since it expects keyboard input,
but only listens for key events on its single, top-level window instead
of subordinate windows (Locally Active) or the root window (Globally
Active).
From the end users prospective, all EWMH/ICCCM compliant WMs (especially
the minimalistic ones) will allow the user to focus mpv, which will allow
mpv to receive key events. If the input field is not set, WMs are
allowed to assume that mpv doesn't require focus.
Commit 9d32d62b61 broke this when it changed OPT_TIME. I simply forgot
to adjust the command definition. The effect was that "no" was not
accepted as value.
I guess this qualifies as trolling. It's becoming increasingly clear
that Microsoft will not be able to deliver on this promise, at least not
in the way they made it seem at first. I'm not sure if Microsoft was the
one who did the trolling, or me. I actually expected that we'd get full
GUI integration of Linux applications including accelerated graphics,
but it was always clear that it wasn't going to work as well as
natively.
In any case, there is no need to frighten any users. The time when you
can run only "Windows Store Apps" on Windows (== the end for mpv and
many other applications on Windows) will come soon enough.
The "faster than native" statement is based on other people's real
experience of software running faster in Linux VMs than native windows
ports, by the way.
This mode drops or repeats audio data to adapt to video speed, instead
of resampling it or such. It was added to deal with SPDIF. The
implementation was part of fill_audio_out_buffers() - the entire
function is something whose complexity exploded in my face, and which I
want to clean up, and this is hopefully a first step.
Put it in a filter, and mess with the shitty glue code. It's all sort of
roundabout and illogical, but that can be rectified later. The important
part is that it works much like the resample or scaletempo filters.
For PCM audio, this does not work on samples anymore. This makes it much
worse. But for PCM you can use saner mechanisms that sound better. Also,
something about PTS tracking is wrong. But not wasting more time on
this.
Can be useful to force it to adapt to extreme speed changes, while a
higher limit would just use a fraction closer to the original video
speed.
Probably useful for testing only.
I'm not sure why it only rendered OSD inside the video. Since OSD
rendering was always done on the X image (after software scaling and
color conversion), there was no technical reason for this. Maybe it was
because the code started out this way, and it was annoying to change it.
Possibly, one reason was that it didn't normally have to clear the black
bars in every frame (if video didn't cover the entire window).
Anyway, simply render OSD to the full window. This gets rid of some
rather weird stuff. It seems to look mostly like vo_wlshm now. The
uncovered regions are cleared every frame, which could probably be
avoided by being clever with the OSD renderer code, but this is where
I'm decidedly losing interest.
There was some mysterious code for aligning the image width to 8 pixels.
Replace that by attempting to align it to SIMD alignment (might matter
for libswscale, or if repack.c gets SIMD). Why are there apparently 4
different ways representing a pixel format (depth, VisualID, Visual,
XVisualInfo), but none of them seem to provide the XImage.bits_per_pixel
value (the actual size of a pixel, including padding)? Even after 33
years, X11 still seems overengineered, confusing, and inconvenient. So
just call X11 a heap of shit, and assume the worst case for alignment.
It may be completely useless, and I can't verify it as no known samples
or other known/accessible software using it, but why not?
Putting this together with he 422 code requires making it slightly more
generic. I'm still staying with a "huge" if tree instead of a table to
select the scanline worker callback, because it's actually small and not
huge (although it not being generic still feels slightly painful).
Now everything is super generic and super undebuggable. Some awkwardness
because the new metadata is basically a transposed version of the
mp_regular_imgfmt metadata, which was used for component info before.
The old code ignored many corner cases, and even wrote "blacker than
black" to YUV images. Use the new pixel format metadata and other
recently added gimmicky crap, which should make this more correct. Even
the almighty fuckup of a format AV_PIX_FMT_UYYVYY411 should work,
although that couldn't be tested for obvious reasons.
This doesn't work for "monow", but this is so extremely fringe while at
the same time painful that I just won't care. In theory, it could be
modeled as some sort of inverted gray colorspace or something.
Make sure to accept only native endian mpv formats. Previously, it
didn't check, and simply matched LE, because these are usually defined
before the BE formats.
red_mask etc. are defined as unsigned long, so use that instead of
hardcoding a 32 bit limit.
A repeat of the previous useless commits.
Pondered whether to use separate fields or just a flags integer for
color and component types; the latter won for now.
Functions like mp_imgfmt_get_component_type() are now discouraged, and
mp_imgfmt_desc.flags is back for defining all information. Some days ago
I felt like the opposite would be the better design. Fortunately, it
doesn't matter.
With this, I think all image format properties that mpv needs are
exhaustively defined all in one place.
Execution of "stop" command in the case when idle mode was not enabled
resulted in player termination scenario not honoring user setting
"save-position-on-quit" from config file. This patch addresses the
issue by checking for "save-position-on-quit" in cmd_stop and saving
state when idle mode is not enabled.
Useless, but super generic! Actually may add support for other fringe
formats, however vo_x11 in itself is useless, so nothing won here. Also
I didn't bother with big endian support.
I guess I decided to stuff it all into mp_imgfmt_desc (the "old"
struct). This is probably a mistake. At first I was afraid that this
struct would get too fat (probably justified, and hereby happened), but
on the other hand mp_imgfmt_get_desc() (which builds the struct) calls
the former mp_imgfmt_get_layout(), and the separation doesn't make too
much sense anyway. Just merge them.
Still, try to keep out the extra info for packed YUV bullshit. I think
the result is OK, and there's as much information as there was before.
The test output changes a little. There's no independent bits[] array
anymore, so formats which did not previously have set this now show it.
(These formats are mpv-only and are still missing the metadata. To be
added later). Also, the output for the cursed packed formats changes.
Use the new pixfmt metadata to replace the format tables with weird
generic code.
As you can see, this removes the tables that essentially duplicate
information (which is baaaaaaaaaad), in exchange for code which is
probably more fragile and has less of a chance of being understood by
someone new to the code (which is probably even worse from a maintenance
and robustness point of view, but LALALA I CAN'T HEAR YOU).
There are some more formats which can be handled like this (RGB30 and
packed YUV I guess), maybe later.
My previous commit added support for this format, but it was still
broken, and prevented the allocation code from working. It's unknown
whether it's correct now (because this pixfmt is so obscure and useless,
there are no known samples around), but who cares.
Trying to use anything other than CLOCK_MONOTONIC here would be a
disaster. No idea if it's even possible for the clockid here to be
something other than CLOCK_MONOTONIC in this function but it's better
safe than sorry. Closes#7740.
I thought I'd probably want something like this, so the hardcoded stuff
in repack.c can be removed eventually. Of course this has no purpose at
all, and will not have any. (For now, this provides only metadata, and
nothing uses it, apart from the "test" that dumps it as text.)
This adds full support for AV_PIX_FMT_UYYVYY411 (probably out of spite,
because the format is 100% useless). Support for some mpv-only formats
is missing, ironically.
The code goes through _lengths_ to try to make sense out of the FFmpeg
AVPixFmtDescriptor data. Which is even more amazing that the new
metadata basically mirrors pixdesc, and just adds to it. Considering
code complexity and speed issues (it takes time to crunch through all
this shit all the time), and especially the fact that pixdesc is very
_incomplete_, it would probably better to have our own table to all
formats. But then we'd not scramble every time FFmpeg adds a new format,
which would be annoying. On the other hand, by using pixdesc, we get the
excitement to see whether this code will work, or break everything in
catastrophic ways.
The data structure still sucks a lot. Maybe I'll redo it again. The text
dump is weirdly differently formatted than the C struct - because I'm
not happy with the representation. Maybe I'll redo it all over again.
In summary: this commit does nothing.
Remove the vaguely defined plane_bits and component_bits fields from
struct mp_imgfmt_desc. Add weird replacements for existing uses. Remove
the bytes[] field, replace uses with bpp[].
Fix some potential alignment issues in existing code. As a compromise,
split mp_image_pixel_ptr() into 2 functions, because I think it's a bad
idea to implicitly round, but for some callers being slightly less
strict is convenient.
This shouldn't really change anything. In fact, it's a 100% useless
change. I'm just cleaning up what I started almost 8 years ago (see
commit 00653a3eb0). With this I've decided to keep mp_imgfmt_desc,
just removing the weird parts, and keeping the saner parts.
The image w and h members must match params.w and params.h, so
should not be changed directly. The helper function mp_image_set_size
is designed for this purpose, so just use that instead.
This prevents an assertion error with the rewritten draw_bmp.
Fixes#7721.
The generate_xxx() helpers, once defined, would appear as
user-visible functions; this would lead to unexpected and
confusing completion suggestions for gene<tab> after having
once run mpv in that shell.
This PR adds the prefix '_mpv_' to all completion functions
as a convention to make them less user-visible and less likely
to collide with other packages.
The OSC calls this "tooltip" (and although a general mechanism, there's
only one instance using it). One particular problem was that with the
default OSC layout, moving the mouse down and out of the window, the
tooltip stuck around, because the returned mouse position was the last
pixel row in the window, which still overlaps with the seek bar.
Instead of introducing mouse_in_window, you could check last_mouse_X for
nil, but I think this is clearer.
This returns (-1, -1) to the caller if the mouse is outside. Kind of
random, but works.
Added in libplacebo v60, unfortunately with some changes in design that
make it a bit of an awkward fit for the way timers are used in mpv.
Timer queries in libplacebo don't support "start" and "stop"-style
operations, and instead are attached directly to operations. The only
sane way of implementing this in the ra API is to have a single 'active
timer' that gets attached to every pass, taking care to sort distinct
operations into distinct pl_timer queries within that ra_timer.
This design unfortunately doesn't let us have multiple 'active timers'
concurrently, similar to the current such limitation in ra_gl. But it's
also not a big deal.
Before this, we pretty much guaranteed that --mpv-ipc-fd=3 would be
passed. The FD was hardcoded, so scripts started by this mechanism
didn't need to actually parse the argument. Change this to using a
mostly random FD number instead.
I decided to do this because posix_spawnp() and the current replacement
cannot "guarantee" a FD layout. posix_spawn_file_actions_adddup2() just
runs dup2() calls, so it may be hard to set FD 3/4 if they are already
used by something else. For example imagine trying to map:
{.fd = 3, .src_fd = 4},
{.fd = 4, .src_fd = 3},
Then it'd do dup2(4, 3), dup2(3, 4) (reminder: dup2(src, dst)), and the
end result is that FD 4 really maps to the original FD 4.
While this was not a problem in the present code, it's too messy that I
don't want to pretend it can always done this way without an unholy
mess. So my assumption is that FDs 0-2 can be freely assigned because
they're never closed (probably...), while for all other FDs only
pass-through is reasonable.
This code runs posix_spawnp() within a fork() in some cases, in order to
"disown" processes which are meant as being started detached. But
posix_spawnp() is not marked as async-signal-safe, so what we do is not
allowed. It could for example cause deadlocks, depending on
implementation and luck at runtime. Turns out posix_spawnp() is useless
crap.
Replace it with "classic" fork() to ensure correctness.
We could probably use another mechanism to start a process "disowned"
than doing a double-fork(). The only problem with "disowning" a process
is calling setsid() (which posix_spawnp() didn't support, but maybe will
in newer revisions), and removing as as parent from the child process
(the double-fork() will make PID 1 the parent). But there is no good way
to either remove us as parent, or to "reap" the PID in a way that is
safe and less of a mess than the current code. This is because
POSIX/UNIX is a miserable heap of shit. (Less shit than "alternatives"
like win32, no doubt.)
Because POSIX/UNIX is a miserable heap of shit, execvp() is also not
specified as async-signal-safe. It's funny how you can run a full
fledged HTTP server in an async-signal-safe context, but not start a
shitty damn process. Unix is really, really, really extremely bad at
this process management stuff. So we reimplement execvp() in an
async-signal-safe way.
The new code assumes that CLOEXEC is a thing. Since POSIX/UNIX is such a
heap of shit, O_CLOEXEC and FD_CLOEXEC were (probably) added at
different times, but both must be present. io.h defines them to 0 if
they don't exist, and in this case the code will error out at runtime.
Surely we could do without CLOEXEC via fallback, but I'll do that only
if at least 1 bug is reported wrt. this issue.
The idea how to report exec() failure or success is from musl. The way
as_execvpe() is also inspired by musl (for example, the list of error
codes that should make it fail is the same as in musl's code).
See manpage additions. This was requested, sort of. Although what has
been requested might be something completely different. So this is
speculative.
This also changes sub_get_text() to return an allocated copy, because
the buffer shit was too damn messy.
This does not normally happen. But since the --input-ipc-client option
can pass in raw FDs, it's probably a good thing in the interest of
making mistakes obvious. Without this, it just burned a core on invalid
FDs (poll() always returned immediately).
As discussed in the referenced issue. This is quite a behavior change,
bit since this option is new, and not included in any releases yet, I
think it's OK.

Render most of the OSD on the CPU, then draw it using a relatively

doesn't matter for vo_direct3d, and the effort spent here is probably
more than this would ever hope, I do hope to simplify the internal OSD
API for all these fringe VOs. Only vo_gpu should be allowed to do more
sophisticated things.)
If your GPU is shit (which it will be if you "want" to use vo_direct3d),
this might actually improve performance... is what I'd say, but out of
laziness a full screen sized texture gets uploaded on every OSD/subtitle
change, so maybe not.
This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)
Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
The original solution for #7017 was sort of a hack, but this hack is no
longer needed because c05e5d9d fixed the underlying issue causing this
error to be spammed in the first place. So just remove the "fix" that
apparently introduced about as many issueas it fixed.
Fixes#7719, hopefully.
Whatever it's worth. Instead of doing a pretty stupid conversion to
float, just blend it directly. This works for most RGB formats that are
8 bits per component or below (the latter because we expand packed
fringe RGB formats for simplicity). For higher bit depth RGB this would
need extra code.
This checked params->color.space for being RGB. If the colorspace is
unset, this did dumb things because even if the imgfmt was a RGB one,
the colorspace was not set to RGB. This actually also happened to the
tests.
(Short-cutting RGB like this is actually wrong, since RGB could still
have strange gamma or primaries, which would warrant a full conversion.
So you'd need to check for these other parameters as well. To be fixed
later.)
This will probably make it slower. But since I don't care about
vo_vaapi, that's perfectly OK. It serves mostly as a test for the
previous commit. In addition, this code was pretty bad (custom broken
scaling and not-blending that probably broke in some situation). If that
wasn't enough, some vaapi drivers also provide only a single overlay at
a time, while this code required a bunch.
There also seems to be a Mesa bug: the overlay gets stretched when
src_x/y was not 0. Or maybe I misunderstood how this is supposed to
work. A bug is probably more likely? Nobody cares about this API.
Maybe this is useful for some of the lesser VOs. It's preferable over
bad ad-hoc solutions based on the more complex sub_bitmap data
structures (as observed e.g. in vo_vaapi.c), and does not use that much
more code since draw_bmp already created such an overlay internally.
But I still wanted something that avoids having to upload/render a full
screen-sized overlay if for example there's only a tiny subtitle line on
the bottom of the screen. So the new API can return a list of modified
pixels (for upload) and non-transparent pixels (for display). The way
these pixel rectangles are computed is a bit dumb and returns dumb
results, but it should be usable, and the implementation can change.
They are sort of confusing, and they hide the fact that they have an
alpha component. Using the actual formats directly is no problem, sicne
these were useful only for big endian systems, something we can't test
anyway.
This was not intended to be committed in 0e3f893606. It disables
the extra wakeup if working==true. I've convinced myself that the wakeup
was really needed at the time, so no idea how I didn't notice this until
someone pointed it out on the commit diff on github (lol).
Bill Gates did not only create COVID, he's also responsible for the
world's worst OS, where you have to literally jump through hoops of fire
to open files with Unicode file names. Lua did not care to implement any
jumping, so it's our turn to jump.
Untested (on win32).
Fixes: #7701
Change it to strictly accept local paths only. No more http://, no more
$HOME expansion with "~/" or mpv config path expansion with "~~/". This
should behave as if passing a path directly to open().
Reduce annoying log noise to further facilitate it using as open()
replacement.
Sometimes it's helpful to override this for specific mp_log instances,
because in some specific circumstances you just want to suppress log
file noise you never want to see.
-1 is an allowed value (for suppressing MSGL_FATAL==0). It looks like
the libplacebo wrapper still does this wrong, so it will probably
trigger UB in some cases. I guess I don't care, though.
This resolves prefixes such as "~/" and "~~/" at the caller, instead of
relying on stream_read_file() to do it. One of the following commits
will remove this from stream_read_file() itself.
Untested.
By default --sub-auto uses "exact". This was far from an "exact" match,
because it added anything that started with the video filename (without
extension), and seemed to end in something that looked like a language
code.
Make this stricter. "exact" still tolerate a language code, but the
video's filename must come before it without any unknown extra
characters. This may not load subtitles in some situations where it
previously did, and where the user might think that the naming
convention is such that it should be considered an exact match.
The subtitle priority sorting seems a bit worthless. I suppose it may
have some value in higher "fuzz" modes (like --sub-auto=fuzzy).
Also remove the mysterious "prio += prio;" line. I probably shouldn't
have checked, but it goes back to commit f16fa9d31 (2003), where someone
wanted to "refine" the priority without changing the rest of the code or
something.
Mostly untested, so have fun.
Fixes: #7702
The caller of render_frame() re-iterates without waiting if this
function returns true. That's normally meant for DS, where we draw
frames as fast as possible to let the driver perform waiting.
draw_bmp.c is the software blender for subtitles and OSD. It's used by
encoding mode (burning subtitles), and some VOs, like vo_drm, vo_x11,
vo_xv, and possibly more.
This changes the algorithm from upsampling the video to 4:4:4 and then
blending to downsampling the OSD and then blending directly to video.
This has far-reaching consequences for its internals, and results in an
effective rewrite.
Since I wanted to avoid un-premultiplying, all blending is done with
premultiplied alpha. That's actually the sane thing to do. The old code
just didn't do it, because it's very weird in YUV fixed point.
Essentially, you'd have to compensate for the chroma centering constant
by subtracting src_alpha/255*128. This seemed so hairy (especially with
correct rounding and high bit depths involved) that I went for using
float.
I think it turned out mostly OK, although it's more complex and less
maintainable than before. reinit() is certainly a bit too long. While it
should be possible to optimize the RGB path more (for example by
blending directly instead of doing the stupid float conversion), this is
probably slower. vo_xv users probably lose in this, because it takes the
slowest path (due to subsampling requirements and using YUV).
Why this rewrite? Nobody knows. I simply forgot the reason. But you'll
have it anyway. Whether or not this would have required a full rewrite,
at least it supports target alpha now (you can for example hard sub
transparent PNGs, if you ever wanted to use mpv for this).
Remove the check in vf_sub. The new draw_bmp.c is not as reliant on
libswscale anymore (mostly uses repack.c now), and osd.c shows an
error message on missing support instead now.
Formats with chroma subsampling of 4 are not supported, because FFmpeg
doesn't provide pixfmt definitions for alpha variants. We could provide
those ourselves (relatively trivial), but why bother.
This provides a way to convert YUV in fixed point (or pseudo-fixed
point; probably best to say "uint") to float, or rather coefficients
to perform such a conversion. Things like colorspace conversion is out
of scope, so this is simple and strictly per-component.
This is somewhat similar to mp_get_csp_mul(), but includes proper color
range expansion and correct chroma centering. The old function even
seems to have a bug, and assumes something about shifted range for full
range YCbCr, which is wrong.
vo_gpu should probably use the new function eventually.
Adding all these so I can use them for obscure processing purposes (see
later draw_bmp commit).
There isn't really a reason why they should exist. On the other hand,
they're just labels for formats that can be handled in a generic way,
and this commit adds support for them in the zimg wrapper and vo_gpu
just by making the formats exist. (Well, vo_gpu had to be fixed in the
previous commit.)
This was incorrect at least because the colorspace matrix attempted to
center chroma at (conceptually) 0.5, instead of 0. Also, it tried to
apply the fixed point shift logic for component sizes > 8 bit.
There is no float yuv format in mpv/ffmpeg yet, but see next commit,
which enables zimg to output it. I'm assuming zimg defines this format
such that luma is in range [0,1] and chroma in range [-0.5,0.5], with
the levels flag being ignored. This is consistent with H264/5 Annex E (I
think...), and it sort of seems to look right, so that's it.
Was broken with a zimg wrapper refucktor before the previous commit. In
addition, it seems this didn't match the vo_drm format, or the format
naming convention. So the order actually changes, and the format is
redefined. (The img_format.h comment was probably wrong.)
Change vo_gpu to the new format as well, so we can still test it.
For whatever purpose. If anything, this makes the zimg wrapper cleaner.
The added tests are not particular exhaustive, but nice to have. This
also makes the scale_zimg.c test pretty useless, because it only tests
repacking (going through the zimg wrapper). In theory, the repack_tests
things could also be used on scalers, but I guess it doesn't matter.
Some things are added over the previous zimg wrapper code. For example,
some fringe formats can now be expanded to 8 bit per component for
convenience.
The OSD is passed to VOs via struct sub_bitmaps, which has a change_id
field. This field is incremented whenever there is a (potential) change
to the other struct contents. If not, the VO can rely on it not having
changed. This must include for example sub_bitmap.x and sub_bitmap.dw.
If these two fields (and y equivalents) change, change_id must change,
even if the subtitle bitmap data might still be the same.
sd_lavc.c stopped respecting this at some unknown point. It could
sometimes cause problems, though usually only with bad and old VOs which
somehow relied on this more than vo_gpu. (I've actually encountered this
before with sd_lavc subtitle scaling, as indicated by a nasty comment,
though probably didn't track this down, since said old VOs can die in a
fire.)
Fix this by maintaining the change_id explicitly. Unfortunately adds
even more code. Instead of comparing the result we could track property
changes, but I think this is better. The number of parts is always very
low with this subtitle decoder, so there's no actual performance issue
to worry about.
This could be triggered by scaling changes (video-zoom etc.), but
probably also changing bitmap subtitle position or scaling.
Should be somewhat helpful. (All VOs are full of code trying to
compensate for this, more or less, and this will allow simplifying
some code later. Maybe.)
The screen size is mostly for robustness checks.
glibc/gcc make certain math functions set errno by default. This is not
required by the standard, and makes everything complexer and slower
(well done glibc). It typically prevents inlining certain math functions
too, where the compiler can turn a function call to a single
instruction, such as observed with lrint().
So this has possibly some minor performance advantages, and no
disadvantages.
Fallback to drmModeAddFB2 if drmModeAddFB2WithModifiers fails. I've
observed it failing on a pinebook pro running manjaro. We also got "0"
as modifiers from FFmpeg anyway, which might or might not have
something to do with this.
Instead of trying to find the source of the problem, just add this
fallback.
Untested (I don't have a platform that requires modifiers to work
here). Might break something, or might fix something. At least this
looks more intuitive to me.
The current implementation of presentation feedback was designed to be
used with flip model presentation. With the bitblt model,
GetFrameStatistics returns totally different values and it's not clear
if we can use them at all. Previously, this wasn't a problem because
with the bitblt model, GetFrameStatistics only worked in exclusive
fullscreen. Now that mpv supports exclusive fullscreen, we should
explicitly check for a flip model swapchain before using presentation
feedback.
This is really basic for planar image data access; not sure why there
weren't such helpers before.
They also handle trickier formats that use bit-packing, or they would be
mich simpler. (This affects only BGR4/BGR4/MONOW/MONOH, I hope whoever
invented them is proud of triggering so many special cases for so little
gain.)
These were still mapped to MP errors during probing, but they also get
triggered when instance creation fails due to lack of support for e.g.
wayland. Since waylandvk is probed above x11vk, we should probably
suppress these by default.
Closes#7626
This brings the displayed percentage closer to the exact number and
allows mpv to more frequently display 100% when it finishes playing a
typical video or audio file.
I have to say this in PR reviews all the time, so maybe I should make i
explicit. In too many words of course, many, many, too many words which
nobody will read, I get it, now shut up. Sneak in some subtle or not so
subtle comments about how I think that github is ruining code quality.
mp.set_osd_ass() (which was undocumented, or in other words, was not
supposed to be used by external scripts) used to do change detection in
the mpv C code. If the resolution or payload did not change, it was not
re-rendered on the lower levels.
Apparently this made some people sad, so fix it. (But only after I told
them to fuck off.) (Well I didn't put it this way, but still.)
For some reason this was never done? Looking through the code, it was
never the case that the frame cache was hit for still frames. I have no
idea why not. It makes a lot of sense to do so.
Notably, this massively improves the performance of updating the OSC
when viewing e.g. large still images, or while paused. (Tested on a
4000x8000 image, the OSC now responds smoothly to user input)
The header probing hacks were previously all broken. They only worked
the first time the archive file was open. Since subsequent opens (on
seek) occured in the middle of the source stream rather than at the
beginning, the stream_read_peek calls meant to retrieve the headers were
instead returning random bytes in the middle of the file.
Perhaps the worst manifestation of this was when seeking within a
multi-volume .rar archive with the "legacy" file naming pattern. If the
seek required a reopen, the fact that the archive was multi-volume would
be forgotten and the file would appear truncated terminating playback.
To solve this, only perform the header probling the first time the
archive is opened. Save the results and reuse them on subsequent
reopens. Put this in a wrapper so this is transparent to
demux_libarchive.
I couldn't find any reason for this message to be so far dispalced from
where it's necessity was determined. That necessity is not however in
question.
Also improve the wording and line breaking.
Making OSD/subtitle bitmaps refcounted was planend a longer time ago,
e.g. the sub_bitmaps.packed field (which refcounts the subtitle bitmap
data) was added in 2016. But nothing benefited much from it, because
struct sub_bitmaps was usually stack allocated, and there was this weird
callback stuff through osd_draw().
Make it possible to get actually refcounted subtitle bitmaps on the OSD
API level. For this, we just copy all subtitle data other than the
bitmaps with sub_bitmaps_copy(). At first, I had planned some fancy
refcount shit, but when that was a big mess and hard to debug and just
boiled to emulating malloc(), I made it a full allocation+copy. This
affects mostly the parts array. With crazy ASS subtitles, this parts
array can get pretty big (thousands of elements or more), in which case
the extra alloc/copy could become performance relevant. But then again
this is just pure bullshit, and I see no need to care. In practice, this
extra work most likely gets drowned out by libass murdering a single
core (while mpv is waiting for it) anyway. So fuck it.
I just wanted this so draw_bmp.c requires only a single call to render
everything. VOs also can benefit from this, because the weird callback
shit isn't necessary anymore (simpler code), but I haven't done anything
about it yet. In general I'd hope this will work towards simplifying the
OSD layer, which is prerequisite for making actual further improvements.
I haven't tested some cases such as the "overlay-add" command. Maybe it
crashes now? Who knows, who cares.
In addition, it might be worthwhile to reduce the code duplication
between all the things that output subtitle bitmaps (with repacking,
image allocation, etc.), but that's orthogonal.
Only _writes_ are aligned, so the assumption doesn't work for reads. But
it's easy to fix by rounding down x0 to the next byte boundary. Writing
pixels outside of the read area is allowed, and we don't go out of
buffer bounds.
Patch by anon32, permission to do anything with it.
This is mostly for testing. It adds passing through the metadata through
the video chain. The metadata can be manipulated with vf_format. Support
for zimg alpha conversion (if built with zimg after it gained alpha
support) is implemented. Support premultiplied input in vo_gpu.
Some things still seem to be buggy.
Used to be used by vo_x11, and some other situations where software
conversion was employed. Haven't seen anyone complain about how software
brightness controls went away (originating from mplayer), so whatever,
it won't be needed again.
This fixes two issues with invalid value after 38/48:
- It was not detected correctly and ended up skipping 4 instead of 0.
- The intent was to skip 0, but it's better to skip the rest.
Behavior with valid 2/5 after 38/48 was correct and is unaffected.
In the wayland code, the left mouse click is treated a bit differently.
Dragging the left click allows mpv to request a window move to the
compositor. In some cases, this can also request a window resize if the
osc-windowcontrols are enabled. These functions had the strange side
effect of messing up mpv's deadzone (it seemed to disappear completely).
A harmless enough workaround is to just explictly send an UP event for
left click after the move/resize functions are finished executing. The
xdg_toplevel move and resize functions both finish after the button
press is let go, so we are guarenteed to have the left click in the UP
state here. Sending this event probably unconfuses some calculation
somewhere thus fixing the deadzone bug. It feels a little silly, but
it's safe and works. Fixes#7651.
When stats.lua is used without a video window then it uses the terminal.
On Windows, however, so far it disabled ansi escape sequences and used
plaintext unless ANSICON env is set.
It's unclear why it's disabled on windows, because at the time it was
added it only used bold by default and mpv ansi emulation on windows
already supported bold at that time.
We can guess that it was disabled because if the same config is used on
both linux and Windows, and it had complex escape sequences for
stats.lue, then it would be emulated incorrectly on Windows.
This shouldn't be an issue anymore, as the last two commits both enhance
the emulation to be quite complete (and graceful where it's not), and
also enable the much-more complete native VT terminal when possible
(Windows 10).
Just remove this windows exception at stats.lua.
This enables native and more complete escape-sequence handling instead
of our emulation. E.g. it supports 256/true colors, and more.
This should get enabled automatically on Windows 10 build 16257
(August 2017) or later.
Previously an SGR sequence was emulated correctly only if:
- It had exactly 1 or 2 numeric values (not 0).
- Only reset, bold, and foreground colors were supported.
- 256/true colors were not skipped correctly with their sub-values.
Now it supports the same as before, plus:
- 0-16 (inclusive) numeric values, e.g. \e[m now resets correctly.
- Supports also codes for background color, reverse, underline* .
- Supports also codes for default intensity/fg/bg/reverse/underline.
- 256/true colors are recognized and skipped gracefully.
* Reverse/underline seem to work only on windows 10.

Move lookup GBRP or planar gray/alpha formats to separate functions in
some cases.
Make setup_regular_rgb_packer() not use a 4:4:4 YUV format to "pass"
RGB. This was used as a "trick" to avoid the stupid GBRP plane
permutation, but it confused severely, so get rid of it. Just do the
reordering, even if the zimg wrapper itself will reorder it back (which
is so stupid that I used the other approach at first). The comment
saying IMGFMT_420P was bogus of course; typically it was IMGFMT_444P.
This was inconsistent for unknown reason. monob was the way we wanted
it, and handling of monow was missing.
See the previous "img_format: add some mpv-only helper formats" commit.
Matters for the zimg wrapper.
mp_imgfmt_get_forced_csp() should be consistent with the MP_CSP_RGB/YUV
flags.
At least the different handling of the XYZ exception was a mess, even if
the result was the same.
Utterly useless, but the intention is to make dealing with corner case
pixel formats (forced upon us by FFmpeg, very rarely) less of a pain.
The zimg wrapper will use them. (It already supports these formats
automatically, but it will help with its internals.)
Y1 is considered RGB, even though gray formats are generally treated as
YUV for various reasons. mpv will default all YUV formats to limited
range internally, which makes no sense for a 1 bit format, so this is a
problem. I wanted to avoid that mp_image_params_guess_csp() (which
applies the default) explicitly checks for an image format, so although
a bit janky, this seems to be a good solution, especially because I
really don't give a shit about these formats, other than having to
handle them. It's notable that AV_PIX_FMT_MONOBLACK (also 1 bit gray,
just packed) already explicitly marked itself as RGB.
When I added mp_regular_imgfmt, I made the chroma subsampling use the
actual chroma division factor, instead of a shift (log2 of the actual
value). I had some ideas about how this was (probably?) more intuitive
and general. But nothing ever uses non-power of 2 subsampling (except
jpeg in rare cases apparently, because the world is a bad place).
Change the fields back to use shifts and rename them to avoid mistakes.
Make this slightly less ad-hoc. Also correct the missing alpha flag for
yap8/yap16.
Despite reduced redundancy, the LOC is going up anyway... whatever.

One not-so-nice hack in the wayland code is the assumption of when a
window is hidden (out of view from the compositor) and an arbitrary
delay for enabling/disabling the usage of presentation time. Since you
do not receive any presentation feedback when a window is hidden on
wayland (a feature or misfeature depending on who you ask), the ust is
updated based on the refresh_nsec statistic gathered from the previous
feedback event.
The flaw with this is that refresh_nsec basically just reports back the
display's refresh rate (1 / refresh_rate * 10^9). It doesn't tell you
how long the vsync interval really was. So as a video is left playing
out of view, the wl->last_queue_display_time becomes increasingly
inaccurate. This led to a vsync spike when bringing the mpv window back
into sight after it was hidden for a period of time. The hack for
working around this is to just wait a while before enabling presentation
time again. The discrepancy between the "bogus"
wl->last_queue_display_time and the actual value you get from the
feedback only happens initially after a switch. If you just discard
those values, you avoid the dramatic vsync spike.
It turns out that there's a smarter way to do this. Just use mp_time_us
deltas. The whole reason for these hacks is because
wl->last_queue_display_time wasn't close enough to how long it would
take for a frame to actually display if it wasn't hidden. Instead, mpv's
internal timer can be used, and the difference between wayland_sync_swap
calls is a close enough proxy for the vsync interval (certainly better
than using the monitor's refresh rate). This avoids the entire conundrum
of massive vsync spikes when bringing the player back into view, and it
means we can get rid of extra crap like wl->hidden.
UB sanitizer complains that aval<<24 (if >=128) cannot be represented as
int. Indeed, we would shift a bit into the sign of an int, which is
probably UB or implementation defined (I can't even remember, but the
stupidity of it burns). So technically, ubsan might be right.
Change aval to uint32_t, which I don't think has a chance of getting
promoted to int. Change the other *val to uint32_t too for cosmetic
symmetry.
So we have to obscure the intention of the code (*val can take only 8
bits) out of language stupidity. How nice. (What a shitty language.)
A mkv sample file was provided to me, which contained a moving PGS
subtitle track, with the same track rendered into the video as
reference. The subtitle track appeared to stutter (while the video one
was smooth). It turns out this was a timestamp rounding issue in mpv.
The subtitle timestamps in the file match the video ones exactly.
They're the same within the mpv demuxer too. Unfortunately, the
conversion from and to libavcodec timestamps is lossy, because mpv uses
a non-integer timebase, while libavcodec supports integers only. See
mp_pts_to_av() and mp_pts_from_av(). The recovered timestamp is almost
the same, but is off by a very minor part. As a result, the timestamps
won't compare equal, and if that happens, display of the subtitle frame
is skipped. Subtitle timestamps don't go through this conversion
because... libavcodec is special? The libavcodec subtitle API is
special.
Fix this by giving it a microsecond of slack. This is basically as if we
used an internal microseconds integer timebase, but only for the purpose
of image subtitle display.
The same could happen to sd_ass, except in practice it doesn't. ASS
subtitles (well, .ass files) inherently use a timebase incompatible to
video, so to ensure frame exactness, ASS timestamps are usually set to
slightly before the video frame's.
Discussion of better solutions:
One could rewrite mpv not to use float timestamps. You'd probably pick
some integer timebase instead (like microseconds), which would avoid the
libavcodec interop issue. At the very least this would be a lot of work.
It would be interesting to know whether the rounding in ther mpv<->lavc
timestamp conversion could be fixed to round-trip in this case. The
conversion tries to avoid problems by using the source timebase (e.g.
milliseconds with mkv). But in general some rounding is unavoidable,
because something between decoder and lowest demuxer layer could
transform the timestamps.
One could extend libavcodec to attach arbitrary information to avpacket
and return it in the resulting avframe. To some degree, such a mechanism
already exists (side data). But there are certain problems that make
this unfeasible and broken.
One could pass through exact mpv float timestamps by reinterpret-casting
them to int64_t, the FFmpeg timestamp type. Actually mpv used to do
this. But there were problems, such as FFmpeg (or things used by FFmpeg)
wanting to interpret the timestamps. Awful shit that make mpv change to
the current approach.
There's probably more but I'm getting bored. With some luck I wasted
precious seconds of your life with my nonsense.
It is more consistent for editions/chapters to go below either

Apparently, this was a bit of a mess, which caused the bug fixed by

definitions.
e1e714ccc introduced a regression here when unloading a track (e.g. on
VO/AO initilization error), due to no corresponding option existing for
video/audio tracks with orders above 0, but the loop in
`mp_deselect_track` being hard-coded to clear tracks up to NUM_PTRACKS.
Introduce the simplest possible hackaround.
In theory this mostly happens automatically, especially after the 5
vsync limit disables this already. But if we uninit before 5 vsyncs are
rendered, this can get left in a dangling 'enabled' state, which leaks a
debug report callback.
Always explicitly disable it just to be on the safe side.
I must have messed this up when I actually added the Y210 format
(because that one is correct). So my comment in the commit adding this
about the FFmpeg pixfmt doxygen being wrong was wrong.
I'd like to use this opportunity to complain once more about the
existence of these terrible pixel formats.
Again worthless, slow, and only for libswscale parity.
With this, we support all formats libswscale supports, except bayer
input, and rgb4/bgr4 output. We even support some formats libswscale
doesn't.
It's possible that the zimg wrapper isn't always as fast as libswscale.
But there is optimization potential: the inner repack loops are
self-contained enough that they could be reasonably be implemented in
assembler (probably), and doing everything slice-wise should reduce the
overhead of the separate pack/unpack stages.
Just lazily tested.
The comment on AV_PIX_FMT_Y210LE seems to be wrong. It claims it's "like
YUYV422", bit it seems more like YVYU422, at last the way libswscale
input treats it. Maybe Intel pays its developers too much?
The repacker inner lop is probably rather inefficient. In theory we
could optimize it by reading the packed pixels as words, doing the
component reshuffling using compile time values etc., but I'd rather
keep the code size small. It's already bad enough that we have to
support 16 bit per component variants, just because this one Intel guy
couldn't keep it in his pants. In general, I can't be bothered to spend
time on optimizing it; I'm only doing this for fun (i.e. masochistic
obligation).
Instead of just picking the last tag that was encountered. The order of
the tags still depends on the file order.
This is probably wrong, and we should respect TargetTypeValue. But
despite staring at the spec, I have no idea what the hell this should
do, so fuck that.
Fixes: #7604
Generic statement about how this is not really appropriate, etc., and
only useful for temporary debugging things, and how I commit it anyway
despite violating my own principles (and how I'd reject this change if
it came from you).
Consider e.g. --aid=2 with a file that has only 1 track. Then it would
fall back to selecting track 1. Stop doing this. If no matching track is
found, this will not select any track now.
Note that the fingerprint stuff (track_layout_hash in the source)
prevents softens the impact of this change. Without the fingerprint,
playing a dual-audio file with the second track selected, and then a
single-audio file, would play the second file without audio. But the
fingerprint resets it due to differences in the track list.
Try to exhaustively document this and tricky interactions between the
other features. What a damn mess, I think it's simply cursed. Of course
it's still my fault.
See: #7608
Some time ago, properties and options were mostly unified. However, the
track selection properties/options semantics are incompatible to this
change. I'm still trying to handle the fallout.
There are two things that are in the way:
1. Track properties somehow return the runtime selection, not the option
value (all while properties are supposed to be aliases to options
with the same name).
2. The user's track options are not supposed to be changed without
interaction. If a track is auto-selected, the property should return
its ID, but the option value should remain at "auto". Only if the
user actually writes to the property the option should change. E.g.
playing e.g. an audio-only file and then a normal video file not play
the video file with --vid=no just because the audio file had no video
track.
In addition to each of them being in conflict with the property/option
unification, attempt to fix one of them breaks the other one.
Today, we're trying to fix parts of this and avoiding an unfortunate
case where you can get a conflicting option/property value, and where
trying to select a track does nothing if the track to select has the
same ID as the option value.
This breaks 2. from above in certain situations. See manpage additions.
See: #7608
Unfortunately, attached pictures (from tags etc.) are treated as video
tracks. That meant --sub-create-cc-track added a CC track for them as
well. Stop doing that.
See: #7608
This covers 8 and 16 bit packed RGB formats. It doesn't really help with
any actual use-cases, other than giving the finger to libswscale.
One problem is with different color depths. For example, rgb565 provides
1 bit more resolution to the green channel. zimg can only dither to a
uniform depth. I tried dithering to the highest depth and shifting away
1 bit for the lower channels, but that looked ugly (or I messed up
somewhere), so instead it dithers to the lowest depth, and adjusts the
value range if needed. Testing with bgr4_byte (extreme case with 1/2/1
depths), it looks more "grainy" (ordered dithering artifacts) than
libswscale, but it also looks cleaner and smoother. It doesn't have
libswscale's weird red-shift. So I call it a success.
Big endian formats need to be handled explicitly; the generic big endian
swapper code assumes byte-aligned components.
Unpacking is done with shifts and 3 LUTs. This is symmetric to the
packer. Using a generated palette might be better, but I preferred to
keep the symmetry, and not having to mess with a generated palette and
the pal8 code.
This uses FFmepg pixfmts constants directly. I would have preferred
keeping zimg completely separate. But neither do I want to add an IMGFMT
alias for every of these formats, nor do I want to extend our imgfmt
code such that it can provide a complete description of each packed RGB
format (similar to FFmpeg pixdesc).
It also appears that FFmpeg pixdesc as well as the FFmpeg pixfmt doxygen
have an error regarding RGB8: the R/B bit depths are swapped. libswscale
appears to be handling them differently. Not completely sure, as this is
the only packed format case with R/B havuing different depths (instead
of G, the middle component, where things are symmetric).
One of the extremely annoying dumb things in ffmpeg is that most pixel
formats are available as little endian and big endian variants. (The
sane way would be having native endian formats only.) Usually, most of
the real codecs use native formats only, while non-native formats are
used by fringe raw codecs only. But the PNG encoders and decoders
unfortunately use big endian formats, and since PNG it such a popular
format, this causes problems for us. In particular, the current zimg
wrapper will refuse to work (and mpv will fall back to sws) when writing
non-8 bit PNGs.
So add non-native endian support to zimg. This is done in a fairly
"generic" way (which means lots of potential for bugs). If input is a
"regular" format (and just byte-swapped), the rest happens
automatically, which happens to cover all interesting formats.
Some things could be more efficient; for example, unpacking is done on
the data before it's passed to the unpacker. You could make endian
swapping part of the actual unpacking process, which might be slightly
faster. You could avoid copying twice in some cases (such as when
there's no actual repacker, or if alignment needs to be corrected). But
I don't really care. It's reasonably fast for the normal case.
Not entirely sure whether this is correct. Some (but not many) formats
are covered by the tests, some I tested manually. Some I can't even
test, because libswscale doesn't support them (like nv20*).
This sucks, but is helpful for testing.
Obviously, it would be much nicer if there were a way to specify _all_
scaler options per filter (if the user wanted), instead of always using
the global options. But this is "too hard" for now. For testing, it is
extremely convenient to select the scaler backend, so add this option,
but make clear that it could go away. We'd delete it once there is a
better mechanism for this.
Edition title is already exposed in demux_edition, it was just never
added to the display. If no edition title exists it will fall back
to the edition number.
Keys and lines-to-scroll are configurabe, and the scroll keys are only
bound on pages which support scrolling (currently only page 4) - also
during oneshot (like the page-switching keys).
Scroll offset is reset for all pages on any key - except scroll keys, so
that entering or switching to a page resets the scroll, as well as when
"re-entering" the same page or "re-activating" the stats oneshot view.
TODO: print_page(..) is highly associated with extending the oneshot
timer if required. The timer handling can probably move into print_page
and removed from all the places which boilerplate its management.
The call was hidden very well, via
dvb_streaming_read -> dvb_update_config
-> dvb_streaming_start -> dvb_set_channel,
and broke the stream buffering logic.
Dropping that call does not noticeably slow down channel switches.
This used 1 MB due to building the complete command and property list
when starting the script. These are needed only for auto-completion, so
build them only on demand. Since building them is fast enough, rebuild
them every time.
The key bindings table is not that much, but saves some KBs. Oddly, the
code to build it uses less memory than the table at runtime (???), so
build it at runtime as well.
Add 2 tactic collectgarbage() calls as well. This frees unused heap when
it is known that the script is going to be completely inactive until
re-enabled by the user.
The buffer can be larger than the normal size when "peeking" is used
(such as done with some file formats, where a large number of bytes masy
need to be "peeked" at the beginning, because FFmpeg). Once normal
operation resumes, it's supposed to free this buffer again. Apparently
this didn't happen as intended, because normal reading did have no way
to discard back buffer before/while resizing the buffer. There's only a
path for discarding the back buffer when actually reading.
It seems like this unfortunately needs 2 code paths for discarding old
data. Just put it into stream_resize_buffer(), where it's rather
non-tricky (discarding can be done by adjusting the copy offset when
moving data to the new allocation). The function now drops old data if
it doesn't fit into the allocation. The caller must ensure that the new
size is sufficient; the function signature changes only so the size of
the implicitly guaranteed kept part can be checked with assert().
In display-sync mode, the core doesn't need to woken up every vsync, but
only every time a new actual video frame needs to be queued. So don't
wake up if there are still frames to repeat.
In audio-sync mode, the wakeup is simply redundant, since there's a
separate timer (in->wakeup_pts) to control when to queue a new frame. I
think.
This finally brings the required playloop iterations down to almost the
number of video frames. (As originally intended, really.)
Also a fairly risky change.
The wakeup at the end of VO frame rendering seems redundant, because
after rendering almost no state changes. The player core can queue a new
frame once frame rendering begins, and there's a separate wakeup for
this. The only thing that actually changes is in->rendering. The only
thing that seems to depend on it and can trigger a wakeup is the
vo_still_displaying() function. Change it so that it needs an explicit
call to a new API function, so we can avoid wakeups in the common case.
The vo_still_displaying() code is mostly just moved around due to
locking and for avoiding forward declarations.
Also a somewhat risky change (tasty new bugs).
This should be unnecessary, since the VO itself performs wakeups once a
new frame can be queued. The only situation I can think of where this
might be required are EOF situations (which are always strange).
If I'm wrong, there'll be fun new bugs, probably causing frame drops or
temporary stalls.
When the player core requests new frames from the filter, this is called
external/recursive filtering, which acts slightly differently from when
filters request new data internally. Mainly this is so the external user
doesn't have to call mp_filter_graph_run() just to get a frame. This
causes a number of complications, and the short version is that until
now, mp_filter_graph_run() has unnecessarily returned true in the
current common case, which made the playloop run too often for no
reason.
The problem is that when a mp_pin is read externally, updating the same
mp_pin during recursive filtering flagged external_pending when the
result was written, which made mp_filter_graph_run() return true, which
made the playloop call mp_filter_graph_run() again. This is redundant
because the caller is obviously checking the new state of the mp_pin
immediately.
The only situation in which external_pending really must be set is if
_another_ pin is changed. In theory, we could also unset it if the set
of "external" pins that are not in a signaled state becomes empty, but
we don't track that in a convenient way.
This commit removes the redundant signaling, and avoids running the
playloop an additional time for each video and audio frame (as it
actually was planned from the beginning, but duh).
If a filter receives an asynchronous wakeup during filtering, then
process newly pending filters resulting from that as well, before
returning to the user. Might possibly skip some redundant playloop
cycles.
There is an explicit comment in the code about how this shouldn't be
done, but I think it makes no sense. Filters have no business trying to
interrupt the mainloop, and mp_filter_graph_interrupt() provides a
proper mechanism to do this (though intended to be used by the filter
user, not filters).
In this case, init_buffers() was not called, and the unrelated cache
sample buffers were not initialized. It appears they are indeed
completely unrelated, so move their initialization away. Not sure what
exactly the purpose of calling init_buffers() is, maybe clearing old
data when displaying stats again. The new place for initializing the
cache sample buffers should achieve the same anyway.
Fixes: #7597
This should make it behave roughly like when switching from a file to
the next (clearing audio buffers, keeping AO, but closing AO if the
audio format seems to have changed and gapless mode is "weak").
Not necessarily useful, but harmless and may help with #7579 (untested).
Replace use of .min==1 with a proper flag. This is a good idea, because
it has nothing to do with numeric limits (also see commit 9d32d62b61
for how this can go wrong).
With this, m_option.min/max are strictly used for numeric limits.
This was optional, with the intention that normally such options require
a valid format. But there is no reason for this (at least not anymore),
and it's actually more logical to accept "no" in all situations this
option type is used. This also gets rid of the weird min field special
use.
These used ".min = MP_NOPTS_VALUE" to indicate certain exceptions. This
broke with the recent change to how min/max are handled, which made
setting min or max mean that a value range is used, thus setting max=0.
Fix this by not using magic a value in .min; replace it with a proper
flag.
Fixes: #7596
This is the proper fix for 1e7802. Turns out the solution is dead
simple: we can still set the allocator with lua_getallocf /
lua_setalloc.
This commit makes memory accounting work on luajit as well.
This is a stopgap measure. In theory we could maybe poll the memory
usage on luajit, but for now, simply reverting this part of fd3caa26
makes Lua work again. (And we can still collect cpu usage metrics)
Proper solution pending (tm)
While --input-file was removed for justified reasons, wanting to pass
down socket FDs this way is legitimate, useful, and easy to implement.
One odd thing is that
Fixes: #7592
Add an infrastructure for collecting performance-related data, use it in
some places. Add rendering of them to stats.lua.
There were two main goals: minimal impact on the normal code and normal
playback. So all these stats_* function calls either happen only during
initialization, or return immediately if no stats collection is going
on. That's why it does this lazily adding of stats entries etc. (a first
iteration made each stats entry an API thing, instead of just a single
stats_ctx, but I thought that was getting too intrusive in the "normal"
code, even if everything gets worse inside of stats.c).
You could get most of this information from various profilers (including
the extremely primitive --dump-stats thing in mpv), but this makes it
easier to see the most important information at once (at least in
theory), partially because we know best about the context of various
things.
Not very happy with this. It's all pretty primitive and dumb. At this
point I just wanted to get over with it, without necessarily having to
revisit it later, but with having my stupid statistics.
Somehow the code feels terrible. There are a lot of meh decisions in
there that could be better or worse (but mostly could be better), and it
just sucks but it's also trivial and uninteresting and does the job. I
guess I hate programming. It's so tedious and the result is always shit.
Anyway, enjoy.
I think that makes more sense.
And also remove the graph from the total cache usage, since that wasn't
very interesting. So there's still a total of 2 graphs.
That's where it comes from after all. The other property does not have
much of a reason to exist anymore, but there's no real reason to remove
it either.
Previously, EGL as provided by a pkg-config was checked for independently
in several places. The effect this had is that --disable-egl would not
actually disable EGL from the build, as this only affected the "egl" option
relied upon by egl-x11. wayland-gl and egl-drm did their own EGL checks.
By making wayland-gl and drm-egl depend on egl instead, we fix this
behaviour and can simplify egl-helpers a bit, as we can now simply
check whether egl or one of the other features providing some non-pc egl
is enabled, instead of checking every single thing that might be pulling
in egl.
Future work could make the "egl" option just be a catchall for any
EGL implementation, so that brcmegl and angle and Android can piggyback
on the egl option as well.
Ancient Linux audio output. Apparently it survived until now, because
some BSDs (but not all) had use of this. But these should work with
ao_sdl or ao_openal too (that's why these AOs exist after all). ao_oss
itself has the problem that it's virtually unmaintainable from my point
of view due to all the subtle (or non-subtle) difference. Look at the
ifdef mess and the multiple code paths (that shouldn't exist) in the
removed source code.
I wonder what this even is. I've never heard of anyone using it, and
can't find a corresponding library that actually builds with it. Good
enough to remove.
It was always marked as "experimental", and had inherent problems that
were never fixed. It was disabled by default, and I don't think anyone
is using it.
May or may not help when dealing with playlist loading in scripts. It's
supposed to help with the mean fact that loading a recursive playlist
will essentially edit the playlist behind the API user's back.
Scripts such as the OSC can be loaded and unloaded at runtime by
toggling the option that enables them. (It even works, although normally
it's only used to control initial loading.)
Unloading was racy because it used the client name; fix this.
The load-script change is an accidental feature. And probably useless.
I mostly intend this for internal purposes. Probably pretty useless for
external API users, but on the other hand trivial to expose. While it
makes a lot of sense internally, I'll probably regret exposing it.
This time is set on every seek (but when initiating it). A new seek
longer than 2 seconds after this is counted as separate seek for the
sake of the revert seek command. If a seek takes a bit longer, this
removes time from these 2 seconds. This commits resets it on the end of
the seek. (Doing anything special for seeks that take longer than 2
seconds is out of scope of this commit.)
Until now, it used only coordinates clipped to the screen for this,
which meant no negative margins were ever reported to libass. This broke
proper rendering of explicitly positioned ASS events (libass simply
could not know the real video size in this case.)
Fix this by reporting margins even if they're negative. This makes it
apparently work correctly with vo_gpu at least.
Note that I'm not really sure if anything in the rendering chain
required non-negative margins. If so, and that code implicitly assumed
it, I suppose crashes and such are possible.
The "rule" is that a fallback warning message should be shown only shown
if software decoding was used before, or in other words when either
hwdec was enabled before, but the stream suddenly falls back, or it was
attempted to enable it at runtime, and it didn't work.
The message wasn't printed the first time in the latter case, because
hwdec_notified was not set in forced software decoding mode. Fix it with
this commit. Fortunately, the logic becomes simpler.
There's no more need to call mp_lua_PITA to get the ctx, and the
autofree prototype is now enforced at the C level at compile time.
Also remove the redundant talloc_free_children at these functions
since it's now freed right after the function completes.
Also, rename auto_free_node to steal_node_allocations to be more
explicit and to avoid confusion with the autofree terminology.
Advantages of this approach:
- All the resources are released right after the function ends
regardless if it threw an error or not, without having to wait
for GC.
- Simpler code.
- Simpler lua setup which most likely uses less memory allocation and
as a result should be quicker, though it wasn't measured.
This commit adds the autofree wrapper and uses it where mp_lua_PITA
was used. It's not yet enforced at the C level, there are still
redundant talloc_free_children leftovers, and there are few more
places which could also use autofree. The next commits will address
those.
Looks like the recent change to this actually made it crash whenever
audio happened to be initialized first, due to not setting the
mux_stream field before the on_ready callback. Mess a way around this.
Also remove a stray unused variable from ao_lavc.c.
Lua changed behavior for this specific event. I considered the change
minor enough that it would not need to go through deprecation, but
someone hit it immediately and ask on the -dev channel.
It's probably better to restore the behavior. But mark it as deprecated,
since it's problematic (mismatch with the C API). Unfortunately, no
automatic warning is possible. (Or maybe it is, by playing sophisticated
Lua tricks such as setting a metatable and overriding indexing, but
let's not.)
Travis is currently having "problems" and is spamming IRC all the time
with pointless failure notifications. Make it so that it hopefully sends
a message only when it goes from success to failure, which should
exclude these cases.
While I'm at it, I'd like to complain how idiotic it is to store CI
configuration in a project's source repository. Such a repository should
only contain things that are inherently part of the code's function, not
part of the organization. You don't store bug reports, build results,
the website, developer access controls, etc. in this repository either.
But for CI it's supposed to be OK? I'm all for this "configuration as
code" thing, but what it should mean is that you store configuration
files in some git managed repository, NOT necessarily that you dump them
into the main source code repo. There are many arguments why it should
not be there, such as this very commit. I have a feeling this is mostly
just because all these idiotic web services just want to advertise their
shit and bind customers by not giving easy ways to treat source code and
CI service configuration orthogonal. And so, the source code repo gets
clobbered with stupid shit (both in the set of files and the commit
history). It's fairly idiotic and my tolerance for it is waning. (Oh, of
course you could probably jump through hoops to make it a separate repo,
but I bet that is complicated and has all kinds of downsides because it
won't be the way "it's meant to be used".)
The VM could throw at pushnode and before mpv_free_node_contents, which
would have resulted in leaked content.
Now this case is handled without leaks.
Note: the lua code still leaks on such case, but mp_lua_PITA doesn't
have destructors like the JS autofree has, which, specifically here,
can do mpv_free_node_contents. So TODO: enhance the lua PITA code to
behave more similar to the JS autofree.
Move some parts that can be generic to the client API code. It turns out
lua.c doesn't need anything special.
This adds the "id" field. I think this was actually missing from the
JSON IPC code (i.e. it's a very recent regression that is fixed with
this commit).
Both Lua and the JSON IPC code need to convert the mpv_event struct (and
everything it points to) to Lua tables or JSON.
I was getting sick of having to make the same changes to Lua and IPC. Do
what has been done everywhere else, and let the core handle this by
going through mpv_node (which is supposed to serve both Lua tables and
JSON, and potentially other scripting language backends). Expose it as
new libmpv API function.
The new API is still a bit "rough" and support for other event types
might be added in the future.
This silently adds support for the playlist_entry_id fields to both Lua
and JSON IPC.
There is a small API change for Lua; I don't think this matters, so I
didn't care about compatibility. The new code in client.c is mashed up
from the Lua and the IPC code. The manpage additions are moved from the
Lua docs, and made slightly more "general".
Some danger for unintended regressions both in Lua and IPC. Also damn
these node functions suck, expect crashes due to UB.
Not sure why this became more code instead of less compared to before
(according to the diff stat), even though some code duplication across
Lua and IPC was removed. Software development sucks.
Unfortunately, merely changing the playlist current position affects the
flags returned by the "playlist" property, so the entirely thing needs
to be marked as changed. Seems to be a design mistake.
Should give a good deal more explicit control and insight over the
player state.
Some feel a bit pointless, and/or expose internal weirdness. However,
it's not like the existing weirdness didn't exist before, or can be made
go away. (In part, the weirdness is because certain in-between states
are visible. Hiding them would make things simpler, but less flexible.)
Maybe this actually gives users a better idea how the API _should_ look
like, too.
On a side note, this tries to really guarantee that mpctx->playing is
set between playback start/end. For that, the loadfile.c changes assume
that mpctx->playing is set (guaranteed by code above the change), and
that playing->filename is set (probably could never be false; was broken
before and actually would have crashed if that could ever happen; in any
case, also add an assert to playlist.c for this).
playlist_entry_to_index() now tolerates playlist_entrys that are not
part of the playlist. This is also needed for mpctx->playing.
It's odd that this state is observable, but is made implicit by making
the property unavailable. It's also odd that an API user cannot directly
put the player into such a state.
Just allow reading/writing -1 (or in fact, any out of bounds index) for
this case.
I'm also refraining from using OPT_CHOICE for the "no selection" case,
because although that would be cleaner in theory, it would cause only
problems to API users due to the more complex property type (worse is
better).
One reason for not restricting the integer range on the input property
anymore is that if there are no playlist elements, the range would
contain only 1 integer, which cannot be represented anymore since the
recent m_option change. This was actually broken with 1 element
playlists before (and still is, with the constricted type for OSD and
the add/cycle commands). Doesn't matter too much.
If the user manages to run a "loadfile x append" command before the loop
in mp_play_files() is entered, then the player could start playing
these. This isn't expected, because appending files to the playlist in
idle mode does not normally start playback. It could happen because
there is a short time window where commands are processed before the
loop is entered (such as running the command when a script is loaded).
The idle mode semantics are pretty weird: if files were provided in
advance (on the command line), then these should be played immediately.
But if idle mode was already entered, and something is appended to the
playlist using "append", i.e. without explicitly triggering playback,
then it should remain in idle mode.
Try to follow this by redefining PT_STOP to strictly mean idle mode.
Remove the playlist->current check from idle_loop(), since only the
stop_play field counts now (cf. what mp_set_playlist_entry() does).
This actually introduces the possibility that playlist->current, and
with it playlist-pos, are set to something, even though playback is not
active or being started. Previously, this was only possible during state
transitions, such as when changing playlist entries.
Very annoyingly, this means the current way MPV_EVENT_IDLE was sent
doesn't work anymore. Logically, idle mode can be "active" even if
idle_loop() was not entered yet (between the time after mp_initialize()
and before the loop in mp_play_files()). Instead of worrying about this,
redo the "idle-active" property, and deprecate the event.
See: #7543
What was this even for? Also, most times, the cleared status line will
show up as an empty new line anyway, so this commit reduces the empty
new lines from 2 to 1.
The code that determines the process exit code ignores all stop_play
values other than PT_QUIT. Generally, PT_ERROR is meaningless outside of
play_current_file(), and is mostly equivalent to PT_NEXT_ENTRY.
Do something that makes it report a non-0 exit code, and indicates in
the terminal exit message that something went wrong.
Untested.
In shared mode, we previously tried to feed the full native format to
IsFormatSupported in the hopes that the "closest match" returned was
actually that.
Turns out, IsFormatSupported will always return the mix format if we
don't use the mix format's sample rate. This will also clobber our
choice of channel map with the mix format channel map even if our
desired channel map is supported due to surround emulation.
The solution is to not bother trying to use anything other than the mix
format sample rate. While we're at it, we might as well use the mix
format PCM sample format (always float32) since this conversion will
happen anyway and may avoid unecessary dithering to intermediate
integer formats if we are already resampling or channel mixing.
Using mpv without libass isn't really supported, since it's not only
used to display ASS subtitles, but all text subtitles, and even OSD.
At least 1 user complained that the player printed a warning if built
without libass. Avoid trying to create the impression that using this
software without libass is in any way supported or desirable, and make
it fully mandatory.
(As far as making dependencies optional goes, I'd rather make ffmpeg
optional, which is an oversized and bloated library, rather than
something tiny like libass.)
Because pthread failures are virtually undebuggable (which sure is
pretty strange, given all these heavy instrumentation tools these days).
Of course it affects only files which include osdep/threads.h.
I'm departing from the usual way to add symbols with config.h and using
"#if", and defining it on the compiler command line + "#ifdef" because I
don't want to include config.h from a header (which would be necessary
in this case) to keep things slightly cleaner. Maybe this is misguided,
but still.
This would have been easier if mpv defined its own wrappers for all
thread functions. But we don't (which to be honest is probably better
than e.g. going crazy like VLC and essentially reimplementing
everything). This seems to be a good compromise. Since it's off by
default and basically a developer tool, the minor undefined behavior
(redefining reserved symbols) isn't much of an issue.
After calling the main filter's destroy callback, all child filters are
destroyed. But one of them still tried to access the cache_lock mutex
(which is destroyed in said destroy callback). This actually caused a
crash on Android with _FORTIFY_SOURCE.
Fix this by destroying the child filters first.
As an unfortunate disaster, min/max values use the type double, which
causes tons of issues with int64_t types. Anyway, OPT_BYTE_SIZE is often
used as maximum for size_t quantities, which can have a size different
from (u)int64_t.
OPT_BYTE_SIZE still uses in64_t, because in theory, you could use it for
file sizes. (demux.c would for example be capable of caching more than
2GB on 32 bit platforms if a file cache is used. Though for some reason
the accounting code still uses size_t, so that use case is broken. But
still insist that it _could_ be used this way.)
There were various inconsistent attempts to set m_option.max to a value
such that the size_t/int64_t upper limit is not exceeded. Due to the
double max field, this didn't really work correctly. Try to fix this
with the M_MAX_MEM_BYTES constant. It's a good approximation, because on
32 bit it should allow 2GB (untested, also would probably exhaust
address space in practice but whatever), and something "high enough" in
64 bit.
For some reason, clang 11 still warns. But I think this might be a clang
bug, or I'm crazy. The result is correct anyway.
Since double has a mantissa too small to hold INT64_MAX in full
precision, converting INT64_MAX to double rounds up. Insert some casts
to silence corresponding warnings (as shown by clang 11).
Also, the comparison in multiply_int64() was incorrect (I think...),
because if v==(double)INT64_MAX, then v==(1<<64), which cannot be
represented as int64_t.
There are probably better ways to solve this.
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with
{"name", ...
followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.
I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.
Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.
Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.
In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.
Previously, the vo wasn't always informed if something about the output
changed during playback. For instance, changing a display's refresh rate
during playback would not update mpv's display fps. Fix this by simply
using VO_EVENT_WIN_STATE in output_handle_done which executes whenever
something about the output is changed.
Forgot to remove this. Here you see my confusion and realization how
casting INT64_MAX to double becomes INT64_MAX+1 (due to mantissa
precision and rounding), so some things seemed not to make sense at
first.
The message_timeout field was basically polled. But ever since the OSC
was changed to work more event based, this didn't quite work. It was
quite visible when switching subtitle or audio tracks while paused (and
with caching disabled, since the cache update triggered some extra
redrawing).
Fix by using a proper timer.
I noticed that changing tracks with the message call commented didn't
redraw properly either, but, uh, I guess the message is always triggered
anyway, and happens to take care of this.
This seems to be an older bug. It set priv->outputfilename to a new
talloc-allocated string, but the field is also managed as string option,
so talloc will free it first, then m_option_free() is called on the
dangling pointer. Possibly this is caused by the earlier ta destruction
order change.
Allow the --window-maximized and --window-minimized flags to actually
work when the player is started. since macOS doesn't like using both at
the same time the minimized state takes precedence over the maximized
state.
The option code is very old and was added to MPlayer in the early 2000s,
when C99 was still new. MPlayer did not use the "bool" type anywhere,l
and the logical option equivalent to bool, the "flag" option type, used
int, with the convention that only the values 0 and 1 are allowed.
mpv may have hammered many, many additional tentacles to the option
code, but some of the basics never changed, and m_option_type_flag still
uses int. This seems a bit weird, since mpv uses bool for booleans. So
finally introduce an m_option_type_bool. To avoid duplicating too much
code, change the flag code to bool, and "reimplement" m_option_type_flag
on top of m_option_type_bool.
As a "demonstration", change the --fullscreen option to this new type.
Ideally, all options would be changed too bool, and m_option_type_flag
would be removed. But that is a lot of monotonous thankless work, so I'm
not doing it, and making it a painful years long transition.
At the same time, I'm introducing a new concept for option declarations.
Instead of OPT_BOOL(), which define the full m_option struct contents,
there's OPTF_BOOL(), which only takes the option field name itself. The
name is provided via a normal struct field initializer. Other fields
(such as flags) can be provided via designated initializers.
The advantage of this is that we don't need tons of nested vararg
macros. We also don't need to deal with 0-sized varargs being a pain
(and in fact they are not a thing in standard C99 and probably C11).
There is no need to provide a mandatory flags argument either, which is
the reason why so many OPT_ macros are used with a "0" argument. (The
flag argument seems to confuse other developers; they either don't
immediately recognize what it is, and sometimes it's supposed to be the
option's default value.)
Not having to mess with the flag argument in such option macros is also
a reason for the removal of M_OPT_RANGE etc., for the better or worse.
The only place that special-cased the _flag option type was in
command.c; change it to use something effectively very similar that
automatically includes the new _bool option type. Everything else should
be transparent to the change. The fullscreen option change should be
transparent too, as C99 bool is basically an integer type that is
clamped to 0/1 (except in Swift, Swift sucks).
Commits ba70b150fb and 8a4f812b76 should have mentioned this. These
things should be quite useful for client API users, and thus should be
mentioned in a prominent place.
Although I'm not sure if anyone will understand from this gibberish what
this really means.
Commit 8d965a1bfb changed option/property min/max handling. As a
consequence, ranges that contain only 1 or 0 elements are not possible
anymore. Normally that's fine, because it makes no sense to have an
option that has only one or none allowed value (statically).
But edition switching used some sort of mechanism where the property can
return a different, dynamically decided range at runtime. That meant
that if there were <2 editions, edition switching with the "cycle"
command would always pick the same value. But with the recent commit,
this changed to having "no range set" and would cycle through all
integer values.
Work this around with a simple change. Now, edition switching on a file
without editions shows "edition: auto" instead of "edition: 0", which
may appear odd. But the former is the --edition default value, and
previous mpv versions rendered the edition property like this when not
using switching.
(Who the fuck uses editions?)
Before this commit, option declarations used M_OPT_MIN/M_OPT_MAX (and
some other identifiers based on these) to signal whether an option had
min/max values. Remove these flags, and make it use a range implicitly
on the condition if min<max is true.
This requires care in all cases when only M_OPT_MIN or M_OPT_MAX were
set (instead of both). Generally, the commit replaces all these
instances with using DBL_MAX/DBL_MIN for the "unset" part of the range.
This also happens to fix some cases where you could pass over-large
values to integer options, which were silently truncated, but now cause
an error.
This commit has some higher potential for regressions.
Try to remove m_config implementation details from m_config_frontend.
Not sure if I like it. Seems to be ~100 lines of awkward code more, and
not much is gained from it. Also it took way too long to do it, and
there might be bugs.
Move the "old" mostly command line parsing and option management related
code to m_config_frontend.c/h. Move the the code that enables other part
of the player to access options to m_config_core.c/h. "frontend" is out
of lack of creativity for a better name.
Unfortunately, the separation isn't quite clean yet. m_config_frontend.c
still references some m_config_core.c implementation details, and
m_config_new() is even left in m_config_core.c for now. There some odd
functions that should be removed as well (marked as "Bad functions").
Fixing these things requires more changes and will be done separately.
struct m_config is left with the current name to reduce diff noise.
Also, since there are a _lot_ source files that include m_config.h, add
a replacement m_config.h that "redirects" to m_config_core.h.
This was mostly unused, and has certain problems. Just get rid of it.
It was still used in CDDA (--cdda-span) and a debug option for OpenGL
(--opengl-check-pattern). Replace both of these with 2 options, where
each sets the start/end values of the former span. Both were
undocumented somehow (normally we require all options to be documented),
so I'm not caring about compatibility, and not bothering to add it to
the API changelog.
The emulation is pretty bad, and C11 compilers are everywhere now. It's
time to retire the emulation, which was always meant as temporary hack
for transition.
In theory, a user can still use --disable-stdatomic to enable the
emulation code, but that's sort of hidden. Actual support will be
removed after the next release or so.
We have this cap now thanks to e2976e662, but we don't actually make
sure our FBOs are storable before we blindly attempt using them with
compute shaders.
There's no more need to unconditionally set `storage_dst = true` as long
as we make sure to include an extra condition on the `fbo_format`
selection to prevent users from accidentally enabling
compute-shader-only features with non-storable FBOs, alongside some
other miscellaneous adjustments to eliminate instances of "assumed
storability" from vo_gpu.
This simply makes the "is the destination FBO format bad?" check a tiny
bit less awful, by making sure we prefer storable FBO formats over
non-storable FBO formats. I'd love to make this also conditional on
whether or not we actually *need* a storable FBO format, but that logic
is decided later, in `pass_draw_to_screen`, and I don't want to
replicate the logic.
Fixes#7017.
Previously if the --fs-screen option was set, it would only use the
screen if mpv was launched with --fs and only on startup. During
runtime, the toggle would ignore it. Rework the logic here so that mpv's
fullscreen always uses --fs-screen if it is set. Additionally, cleanup
some unneeded cruft in vo_wayland_reconfig and make find_output more
useful.
Really minor detail that doesn't really matter. If frame stepping pauses
playback on end (why does this special case even exist), it should
probably be done after on_unload, because all works is supposed to be
finished at that point.
This was not reset in the num_properties==0 case. This didn't really
matter, but for debugging it's slightly nicer to see new_property_events
reset once the client thread is done with it.
Change to it 1000 hours, which is "infinite" enough. (Hesitant to use
INFINITY, as that is not in the option's range. The option parser
rejects it because it causes only problems in API users and so on.)
Until now the 'update' method used mp.command_native with a hardcoded
list of key names.
Change it to use whatever keys the user set to this object, so that
we can remain oblivious to new keys which 'osd-overlay' may support.
This is how the lua code did it from the begining. We didn't, and now
we pay the price.
Note: could be implemented either as we have now (clone `this`
excluding the methods) or by moving the methods up the prototype chain
(i.e. class methods) so they don't get enumerated and use `this` as
the command object itself.
However, in the latter approach we'll have to save the values which we
change (name, res_x, res_y) and restore them after the command, so it's
simpler to just clone `this`.
When the current file changes (or rather, when starting/finishing
playback of a playlist entry), clients tend to have the problem that
it's hard to tell whether a property change notification (via
mpv_observe_property() and mechanisms layered on top of it) is from the
previous or new playlist entry. The previous commit probably helps, but
all the asynchronity is still a bit unhelpful.
Try to make this better by adding new hooks, that are run before/after
playback init/deinit. This is similar to the existing hooks, except
they're outside of "initialized" playback, which excludes that you might
accidentally get an overlap between the current and the previous/next
playlist entry.
That still doesn't seem quite enough, since normally, property change
notifications come after the hook event. So basically a client would
have to explicitly "drain" the event queue within the hook, and make the
hook continue only after that is done. Knowing when property
notifications are done is another asynchronous nightmare (how exactly it
works keeps changing within client.c, and an API user probably can't
tell anymore when all pending properties are truly done). So introduce
another guarantee: properties that were changed before the hook happens
will be returned before the hook event is returned. That means the
client will have received all pending property notifications from the
previous playlist entry (or whatever) before the hook is entered.
As another minor complication, we shouldn't just keep the hook pending
until _all_ property notifications are done, since the client's hook
could produce new ones. (Or just consider things like the demuxer thread
hammering the client with cache update events, while the "on_preloaded"
hook is run.) So there is some extra untested, fragile logic in client.c
to handle this (the waiting_for_hook flag).
This probably works, but was barely tested. Not sure if this helps
anyone, but I think it's fine for my own purposes. (I really hated this
aspect of the API whenever I used it myself.)
This could happen if a property was flagged as changed, then updated,
then flagged again, but gen_property_change_event() was called before
the value was updated a second time. Then the function simply returned
the old value, and would later trigger a new change event again.
This was considered acceptable before, since property notifications are
asynchronous anyway (so they may always be "outdated", it just mattered
whether the most recent value was eventually delivered).
But consider ordering with events. It seems desirable that specific
important events (e.g. MPV_EVENT_START_FILE) should not be followed by
property updates that happened before it, because that would make
application logic really a mess, and property notification near-useless
in certain cases.
Avoid this by never returning a value if it was marked changed, but not
updated yet.
Unfortunately, this could lead to clients never receiving a value (or
receiving it with a high random delay), if they're too slow to read it
(or the property simply updates too often). Note that this is done for
_all_ property notifications, not just returned events. Hopefully not a
problem in practice. If it turns out to be one, this mechanism could be
restricted to actually returned events, for which this really matters.
No replacement. Qt or C++ code has no business in this repository, and
new code (even if it uses Qt) should not use it. Get rid of it.
We consider the libmpv API itself as stable. Symbols can be deprecated,
but not be removed. However, qthelper.hpp was never considered part of
the libmpv API. There no ABI implications either, since it's a header-
only implementation that uses C API symbols only. It's just a header
provided for convenience for Qt/C++ programs (i.e. extremely limited
usefulness).
This is more or less a minimal hack to make _some_ text measurement
functionality available to scripts. Since libass does not support such a
thing, this simply uses the bounding box of the rendered text.
This is far from ideal. Problems include:
- using a bitmap bounding box
- additional memory waste and/or flushing caches
- dependency on window size
- odd small deviations with different window sizes (run osd-test.lua and
resize the window after each timer update; the bounding boxes aren't
adjusted in an overly useful way)
- inability to query the size _after_ actual rendering
But I guess it's a start. Since I'm aware that it's crap, add a threat
to the manpage that this may be changed/removed again. For now, I'm
interested whether anyone will have use for it in its current form, as
it's an often requested feature.
When the demuxer cache read until the end of the stream, and was
finished and completely inactive, the cache properties were not updated
anymore via MP_EVENT_CACHE_UPDATE.
Unfortunately, many cache properties depend on the current playback
position, such as cache-duration or fw-bytes. This is especially visible
on the OSC. If everything was cached, seeking around didn't update the
displayed forward cache duration.
That means checking demuxer_reader_state.idle is not enough. You also
need to check whether the current playback position changed.
Fix this by explicitly using the current playback position, and update
the properties if it changed "enough". "Enough" is 1 second of media
time in this example, which may or may not be appropriate.
In general, this could probably be done better. There are many other
triggers that change the cache state and that are not covered. For now
I'm content with getting rid of the obvious problems.
I think the OSC problem in particular was caused by changing it from
polling to using property change notifications.
Apparently this bit-rotted a lot, and now causes more problems that it
helps. In particular picking up broadcom EGL instead of Mesa EGL will
break things. With RPI getting proper Mesa/DRM/V4L support, this problem
should solve itself as well.
Some filters may block the playloop for a longer time. For example, if a
decoder fails to decode anything and somehow just discards packets, the
filter graph would run (in a blocking manner) until all packets are
read, which could take a longer time if the demuxer thread is fast
enough.
Make it exit every 100ms. That should at least give the user a chance to
stop playback.
Filtering could run on a different thread, but I don't see much value in
doing that in the general case. It would just waste a thread. Although
being able to use mp_filter_graph_interrupt() would be slightly nicer
than such a timeout mechanism. Decoding in particular can actually use a
separate thread (--vd-queue-enable), but again, this is not enabled by
default, because it just wastes a thread.
Like the previous f_decoder_wrapper commit, this is probably a sin.
The mp_filter_run() invocation blocks as long as the demuxer provides
packets and the queue can be filled. That means it may block quite a
long time of the decoder queue size is large (since we use libavcodec in
a blocking manner; it regrettably does not have an async. API).
This made the main thread freeze in certain situations, because it has
to wait on the decoder thread.
Other than I suspected (I wrote that code, but that doesn't mean I know
how the hell it works), this did not freeze during seeking: seek resets
flushed the queue, which also prevented the decoder thread from adding
more frames to it, thus stopping decoding and responding to the main
thread in time. But it does fix the issue that exiting the player waited
for the decoder to finish filling the queue when stopping playback.
(This happened because it called mp_decoder_wrapper_set_play_dir()
before any resets. Related to the somewhat messy way play_dir is
generally set. But it affects all "synchronous" decoder wrapper API
calls.)
This uses pretty weird mechanisms in filter.h and dispatch.h. The
resulting durr hurr interactions are probably hard to follow, and this
whole thing is a sin. On the other hand, this is a _very_ user visible
issue, and I'm happy that it can be fixed in such an unintrusive way.
p->log has a prefix set that gives some context and distinguishes audio
and video decoders. The "public" wrapper filter didn't use it, which is
a regression since commit a3823ce0e0.
Filtering is integrated into an event loop, which is something the
filter API user provides. To make interacting with the event loop
easier, and in particular to avoid filtering to block event handling,
add functions the event loop code can suspend filtering.
While we cannot actually suspend a single filter, it's pretty easy to
suspend the filter graph run loop itself, which is responsible for
selecting which filter to run next.
This commit shouldn't change behavior at all, but the functions will be
used in later commits.
This was forgotten.
Hardware decoding typically breaks immediately, because many hw decoding
APIs require allocating all surfaces in advance (and/or libavcodec was
not made flexible enough to add new surfaces later). If the queue is
large enough, it will run out of surfaces, fail decoding, and fall back
to software decoding. We consider this the user's fault.
--hwdec-extra-frames can be used to avoid this, if you have enough GPU
memory, and the needed number of frames is lower than the arbitrary
mpv-set maximum limit of that option.
I don't know what should happen when the same value is written to the
property. It seems that it would be more natural if it were ignored
(since that's also what is done with options now), but you could argue
the other way around as well. In any case, changing it silently could
leads to user scripts etc. breaking, so don't change it now.
Instead, add blabla to the manpage to put the responsibility on the
user, so when we suddenly change it one day, we can blame any breakages
on someone else.
See: #7501
This required libsmbclient, which is a heavy dependency, and as a
library, has all kinds of problems. For one, the API requires completely
unacceptable global state (in particular, leaks auth state), and is not
thread-safe (meaning concurrent reads to multiple files block each
other).
There are better replacements: you can use the Linux kernel's builtin
CIFS support, fusesmb, or contribute supoport for libdsm.
This commit fixes a bug where handle for a framebuffer gets double
freed.
It seems to happen that the same prime fd gets two framebuffers.
As the prime fd is the same the resulting prime handle is also the
same.
This means one handle but 2 framebuffers and can lead to the following
chain:
1. The first framebuffer gets deleted the handle gets also freed via
the ioctl.
2. In startup phase not all 4 dumb buffers for overlay drawing
are set up. It can happen that the last dumb buffer gets the
handle we freed above.
3. The second framebuffer gets freed and the handle will be
freed again resulting that the 4's dumb buffer handle is not
backed by a buffer.
4. Drm prime continues to assign handles to its prime fds an
will lead to have this handle which was just freed to
reassign again but to an prime buffer.
5.Now the overlay should be drawn into dumb buffer 4 which
still has the same handle but is backed by the wrong buffer.
This leads to two different behaviors:
- MPV crashes as the drm prime buffers size als calculated
by the decoder output format. The overlay output format
differs and it takes more space. SO the size check
in kernel fails.
- MPV is continuing play. This happens when the decoders
allocates a bigger buffer than needed for the overlay.
For example overlay is Full HD and decoder output is 4k.
This leads to the behavior das the overlay wil be drawn
into the wrong buffer as its a drm prime buffer and results
in a flicker every fourth step.
Instead of having f_decoder_wrapper create its own copy of the entire
mpv option tree, create a struct local to that file and move all used
options to there.
movie_aspect is used by the "video-aspect" deprecated property code. I
think it's probably better not to remove the property yet, but
fortunately it's easy to work around without needing special handling
for this option or so.
correct_pts is used to prevent use of hr-seek in playloop.c. Ignore
that, if you use --no-correct-pts you're asking for trouble anyway. This
is the only behavior change.
The demuxer cache employs a strange method to make track switching
instant with caching enabled. Normally this would mean you have to wait
until the cache has played out (and you get new packets, including
packets from the newly selected track), or you have to perform a slow
high level seek (decoding video again etc.). The strange method is that
it performs a demuxer-level seek without a high level seek so it looks
like a continuous stream to the decoder, and the newly select stream
gets packets at the current playback position. This is called a refresh
seek.
This works only if some weird heuristics work. It needs a packet "unique
ID", for which it uses either dts or pts. The value must be strictly
monotonic increasing. If this doesn't work, the referesh seek can't be
executed, and the user has to wait until the end of the cache. Sometimes
there are files that simply do not work.
In the present case, there's actually a hack that we can extend. Packets
with unset position are likely generated by the parser, and the hack
which this commit touches simply attempts to make up a new (hopefully
unique) position value, even if the value itself makes no sense. It only
ha to be deterministic.
It turns out libavcodec sometimes output packets with repeating position
values. This commit tries to handle this case too with the same hack.
Fixes: #7498
Let's see how much everyone hates this. Leaving it enabled seems
problematic, because libavcodec returns an unspecific error if it
doesn't like it.
Fixes: #6300
See manpage additions. This has been a topic in MPlayer/mplayer2/mpv
since forever. But since libavcodec multi-threaded decoding was added,
I've always considered this pointless. libavcodec requires you to
"preload" it with packets, and then you can pretty much avoid blocking
on it, if decoding is fast enough.
But in some cases, a decoupled decoder thread _might_ help. Users have
for example come up with cases where decoding video in a separate
process and piping it as raw video to mpv helped. (Or my memory is
false, and it was about vapoursynth filtering, who knows.) So let's just
see whether this helps with anything.
Note that this would have been _much_ easier if libavcodec had an
asynchronous (or rather, non-blocking) API. It could probably have
easily gained that with a small change to its multi-threading code and a
small extension to its API, but I guess not.
Unfortunately, this uglifies f_decoder_wrapper quite a lot. Part of this
is due to annoying corner cases like legacy frame dropping and hardware
decoder state. These could probably be prettified later on.
There is also a change in playloop.c: this is because there is a need to
coordinate playback resets between demuxer thread, decoder thread, and
playback logic. I think this SEEK_BLOCK idea worked out reasonably well.
There are still a number of problems. For example, if the demuxer cache
is full, the decoder thread will simply block hard until the output
queue is full, which interferes with seeking. Could also be improved
later. Hardware decoding will probably die in a fire, because it will
run out of surfaces quickly. We could reduce the queue to size 1...
maybe later. We could update the queue options at runtime easily, but
currently I'm not going to bother.
I could only have put the lavc wrapper itself on a separate thread. But
there is some annoying interaction with EDL and backward playback shit,
and also you would have had to loop demuxer packets through the
playloop, so this sounded less annoying.
The food my mother made for us today was delicious.
Because audio uses the same code, also for audio (even if completely
pointless).
Fixes: #6926
This is supposed to enable communication between filter graphs on
separate threads. Having multiple threads makes only sense if they can
run concurrently with each other, which requires such an asynchronous
queue as a building block. (Probably.)
The basic idea is that you have two independent filters, which can be
each part of separate filter graphs, but which communicate into one
direction with an explicit queue. This is rather similar to unix pipes.
Just like unix pipes, the queue is limited in size, so that still some
data flow control enforced, and runaway memory usage is avoided.
This implementation is pretty dumb. In theory, you could avoid avoid
waking up the filter graphs in quite a lot of situations. For example,
you don't need to wake up the consumer filter if there are already
frames queued. Also, you could add "watermarks" that set a threshold at
which producer or consumer should be woken up to produce/consume more
frames (this would generally serve to "batch" multiple frames at once,
instead of performing high-frequency wakeups). But this is hard, so the
code is dumb. (I just deleted all related code when I still got
situations where wakeups were lost.)
This is actually salvaged and modified from a much older branch I had
lying around. It will be used in the next commit.
Instead of vague ideas about making different filter graphs on different
threads interact directly, this have no direct support. Instead, helpers
are required (such as added with the next commit).
Document it. Different root filters (i.e. separate filter graphs) are
now considered to be part of separate threads, so assert() if they're
found to accidentally interact.
Previously: 5.1 > 5.2 > luajit
Now: 5.2 > luajit > 5.1
I randomly decided that this should be done, since I suspect most
environments will prefer the highest Lua version anyway. There is not
much of a point picking the older one by default.
Maybe 5.1 should be dropped fully, but considering we need to stay
compatible with luajit, there is no particular incentive for this.
Preparation for a future commit. The demuxer queues might be read from
other threads than the one to issue the seek, and passing SEEK_BLOCK
with such a seek will provide a convenient way to synchronize this.
mp_filter_mark_async_progress() can asynchronously mark a filter for
processing, without waking up the filter thread. (It's some sort of
idiotic micro-optimization I guess?) But since it sets async_pending
without doing the wakeup, a mp_filter_wakeup() after this will do
nothing, and the wakeup is lost. Fix it by checking for the needed
wakeup separately.
Fortunately, nothing used this function yet, so there is no impact.
I may (optionally) move decoding to a separate thread in a future
change. It's a bit attractive to move the entire decoder wrapper to
there, so if the demuxer has a new packet, it doesn't have to wake up
the main thread, and can directly wake up the decoder. (Although that's
bullshit, since there's a queue in between, and libavcodec's
multi-threaded decoding plays cross-threads ping pong with packets
anyway. On the other hand, the main thread would still have to shuffle
the packets around, so whatever, just seems like better design.)
As preparation, there shouldn't be any mutable state exposed by the
wrapper. But there's still a large number of corner-caseish crap, so
just use setters/getters for them. This recorder thing will inherently
not work, so it'll have to be disabled if threads are used.
This is a bit painful, but probably still the right thing. Like
speculatively pulling teeth.
This explicitly depends on the pixfmt list from FFmpeg (done so to
easily spot regression, incompatible changes, and other unexpected
things).
Some local changes in mpv change some of the output. For pal8 an alias
was added back, and the [GENERIC] markers are removed because the mpv
aliases are not dependent on the mpv config anymore (which was
unnecessary).
The other changes are due to ffmpeg adding some new formats.
This was a hack that attempted to line up external audio tracks with
video. The problem is that if you do a keyframe seek backwards, video
will usually seek much farther back than audio (due to much higher
keyframe aka seek point distances). The hack somehow made seeking a 2
step process.
This existed in 4 different forms in the history of this code base, and
it was always very cumbersome. We mostly needed this for ytdl_hook (I
think?), which uses the 4th form, which is nicely confined to
demux_timeline and is unrelated to the "external" audio tracks in the
high level player.
Since this is (probably) not really widely needed anymore, get rid of
it. Better do this now, than when somehow rewriting all the seeking code
(which might happen in this decade or the next or so) and when it
wouldn't be easily revertable anymore in case we find we "really" need
it unlike expected.
There is no issue if hr-seeks are used. Also, you can still use edl
files to "bundle" multiple streams as if it was a single stream (this is
what ytdl_hook does now).
It seems sporadic errors are possible, such as connection timeouts.
Before the recent demuxer change, the demuxer thread retried many times
even on EOF, so an error was only interpreted as EOF once the decoder
queues ran out.
Change it to use EOF only. Since this may actually lead to the demuxer
thread being "stuck" and retrying forever (depending on libavformat API
behavior), I'm also adding a heuristic to prevent this, using a random
retry counter. This should not be necessary, but libavformat cannot be
trusted. (This retrying forever could be stopped by the user, but
obviously it would still heat the CPU for a longer time if the user is
not present.)
The "seekbarkeyframes" option is now interpreted such if it's true, the
player default is used. Too lazy to make this a choice option or
whatever; the Lua option parser doesn't have support for that anyway.
Someone who cares can adjust this.
Try to deal with various corner cases. But when I fix one thing, another
thing breaks. (And it's 50/50 whether I find the breakage immediately or
a few months later.) So results may vary.
The default for--hr-seek is changed to "default" (not creative enough to
find a better name). In this mode, audio seeking is exact if there is no
video, or if the video has only a single frame. This change is actually
pretty dumb, since audio frames are usually small enough that exact
seeking does not really add much. But it gets rid of some weird special
cases.
Internally, the most important change is that is_coverart and is_sparse
handling is merged. is_sparse was originally just a special case for
weird .ts streams that have the corresponding low-level flag set. The
idea is that they're pretty similar anyway, so this would reduce the
number of corner cases. But I'm not sure if this doesn't break the
original intended use case for it (I don't have a sample anyway).
This changes last-frame handling, and respects the duration of the last
frame only if audio is disabled. This is mostly "coincidental" due to
the need to make seeking past EOF trigger player exit, and is caused by
setting STATUS_EOF early. On the other hand, this might have been this
way before (see removed chunk close to it).
This tries to fix#7206 (hr-seeking past EOF does not stop playback)
again. Commit 57fbc9cd76 should have fixed this, but trying it again
(using that git revision), it often did not work. Whatever the fuck.
So add another dumb special case that will break within weeks. Note that
the check in handle_eof() had no effect, since execute_queued_seek() is
called later, which cancels EOF in the same case.
Hr-seek past the last frame instantly enters EOF, which means
handle_playback_time() will not set playback_pts to the video PTS (as
all video frames are skipped), which leads to the playback time being
taken from the last seek target. This results in confusing behavior,
especially since the seek time will be clipped to the file duration for
display, but not for further relative seeks.
Obviously, the time should be set to the last video frame, so use the
last video frame as fallback if both audio and video have ended. Also,
since the same problem exists with audio-only playback, add a fallback
for audio PTS too. We don't know which was the "last" fragment of media
played (to decide whether to use the audio or video PTS as the
fallback), but it doesn't matter since the maximum works.
This could lead to some undesired effects. In particular the audio PTS
is basically a bad guess, and is for example not clipped against --end.
(But the ridiculous way audio syncing and clamping currently works, I'm
not going to touch that shit unless I rewrite it completely.) The cover
art case is slightly broken: using --keep-open with keyframe seeks will
result in 0 as playback PTS (the video PTS). OK, who cares, it got late.
Also casually get rid of last_vo_pts, since that barely made any sense
at all.
Fixes: #7487
The seeking logic saves the last video frame it has seen (for example
for being able to seek to the last frame, or backstepping).
Unfortunately, the frame was fed back to the filtering pipeline in
situations when it shouldn't have. Then it's an out of order frame,
because it really saves the last _discarded_ frame.
For example, seeking to the end of a file with --keep-open, shift+up,
shift+down => invalid video pts warning due to saved_frame being fed
back.
Explicitly discard saved_frame when it's obviously not needed anymore.
The removed accesses to "r" are strictly speaking unrelated (just
const-propagating them).
In this case the video track has seek_start == seek_end, and due to the
"seek_start >= seek_end" condition, this was considered broken, and no
seek range was created, breaking cached seeking.
Fix this by allowing the case if they're equal, and a valid timestamp.
(NB: seeking backward in this will still jump to position 0, because it
is the video timestamp. This is unfortunately how it's supposed to work.
HR-seeks will also do this, but decode and skip the entire audio until
the seek target, so it will mostly appear to work.)
Exposed by commit b56e2efd5f. demux_timeline reported a bogus EOF if
"parallel" streams were used. If a virtual source reported EOF, it was
propagated as global EOF, without serving packets of other virtual
sources that have not ended yet.
Fix this by not reporting global EOF just because a source has not
returned a packet. Instead make the reader retry by returning no packet
and no EOF state, which will call d_read_packet() again with a different
source. Rely on the eof_reached flags to signal global EOF.
Since eof_reached is now more important, set it in a certain other case
when it apparently should have been set. do_read_next_packet()'s return
value is now ignored, so get rid of it.
This is useful with live streams, and it's not much worse than the h264
first packet hack, which reads some data anyway.
For some reason, the option wasn't even documented, so do that.
In addition, print the start time even if it's negative. That should not
be possible, but for some reason, the field is an int64_t copied from an
uint64_t so... whatever. Keeping the logging slightly more straight
forward is better anyway.
Remove some redundant fields that controlled or indicated whether the
demuxer was/could/should prefetch. Redefine how the eof/reading fields
work.
The in->eof field is now always valid, instead of weirdly being reset to
false in random situations. The in->reading field now corresponds to
whether the demuxer thread is working at all, and is reset if it stops
doing anything.
Also, I always found it stupid that dequeue_packet() forced the demuxer
thread to retry reading if it was EOF. This makes little sense, but was
probably added for files that are being appended to (running downloads).
It makes no sense, because if the cache really tried to read until file
EOF, it would encounter partial packets and throw errors, so all is lost
anyway. Plus stream_file now handles this better. So stop this behavior,
but add a temporary option that enables the old behavior.
I think checking for ds->eager when enabling prefetching never really
made sense (could be debated, but no, not really). On the other hand,
the change above exposed a missing wakeup in the backward demuxing code.
Some chances of regressions that could make it stuck in certain states
or so, or incorrect demuxer cache state reporting to the player
frontend.
Setting demux_set_stream_wakeup_cb() will make all sh_stream (i.e.
track) specific wakeups go to this callback. But the callback takes care
of only the sub_preload() case (where it tries to pre-load subtitles
from already parsed and memory-present subtitles in a blocking way).
The old code assumed that the normal demuxer wakeup callback is called.
This was disregarded when the newer code was added. (And actually, the
original plan was to make _all_ per-sh_stream wakeups go to specialized
callbacks to avoid wasted work. dec_sub really should set the callback
always, and propagate wakeups to the playloop code. But it's too far
into the night to write coherent code.)
I couldn't actually observe any manifestation of this bug. Normally, the
playloop wakes up for other reasons (such as driving audio and video
decoding), so the lost wakeups rarely matter.
A negative subtitle delay means that subtitles from the future should be
shown earlier. With muxed subtitles, subtitle packets are demuxed along
with audio and video packets. But since they are demuxed "lazily",
nothing guarantees that subtitle packets from the future are available
in time.
Typically, the user-observed effect is that subtitles do not appear at
all (or too late) with large negative --sub-delay values, but that using
--cache might fix this.
Make this behave better. Automatically extend read-ahead to as much as
needed by the subtitles. It seems it's the easiest to pass the subtitle
render timestamp to the demuxer in order to guarantee that everything is
read. This timestamp based approach might be fragile, so disable it if
no negative sub-delay is used.
As far as the player frontend part is concerned, this makes use of the
code path for external subtitles, which are not lazily demuxed, and may
already trigger waiting.
Fixes: #7484
Subtitle tracks are usually "lazy" (ds->eager=false), There are a number
of weird special cases associated with it. One of them is that they have
some sort of "temporary" EOF (to signal that there isn't a packet right
now, and the decoder should not block playback by waiting for more
packets). In a the next commit, I want to call mark_stream_eof() in case
of (some) of these temporary EOFs.
The problem is that mark_stream_eof() also calls the functions touched
by this commit. Basically they shouldn't do any complex work due to
these temporary EOFs (because they might happen very often). It turns
out that lazy tracks barely matter here: they do not extend the seek
range of a packet/EOF happens on them, they do not trigger seek range
joining, and they do not support backward demuxing.
This change should enable the following commit, while not causing any
behavior changes (i.e. bugs) with the current state.
args->client was deallocated if the FDs were closed and nothing
referenced it (IPC socket codes detected the closed sockets and
asynchronously killed the mpv_handle in args->client). The problem was
that args->log depended on it, and was also destroyed.
Fix this by duplicating the mp_log.
This has been part of the libmpv for a while, so the implementation in
the IPC code is quite simple: just pass the mpv_node representing the
value of the "command" field without further checks to
mpv_command_node().
The only problem are the IPC-specific commands, which essentially have
their own dispatch mechanism. They expect an array. I'm not going to
rewrite the dispatch mechanism, so these still work only with an array.
I decided make the other case explicit with cmd==NULL. (I could also
have set cmd=="", which would have avoided changing each if condition
since "" matches no existing command, but that felt dirty.)
I decided to make this explicit. The alternative would have been making
all commands asynchronous always, like a small note in the manpage
threatened. I think that could have caused compatibility issues.
As a design decision, this does not send a reply if an async command
started. This could be a good or bad idea, but in any case, it will make
async command look almost like synchronous ones, except they don't block
the IPC protocol.
The relatively recently added property update code has a race condition
when clients exit. It still tried to access mpv_handle during and after
it was destroyed.
The reason is that it unlocks the lock for the mpv_handle list (while
mpv_handle is locked), but nothing in mp_destroy_client() cares about
this case. The latter function locks mpv_handle only before/while it
makes sure all of its activity is coming to an end, such as asynchronous
requests, and property updates that are in progress. It did not include
the case when mp_client_send_property_changes() was still calling
send_client_property_changes() with mpv_handle locked.
Fix this by checking the mpv_handle.destroying field. This field can be
set only when mpv_handle is locked. While we're checking the lock, the
mpv_handle list is still locked, so at worst we might be at the point
before mp_destroy_client() locks the list again and finally destroys the
mpv_handle.
This is a hard to reproduce race condition which I spotted only once in
valgrind by chance, so the fix is unconfirmed.
The previous change ensured that these cannot fail anymore (much like in
original talloc). Change the APIs to not return a success value anymore,
to "cement" this.
The ta_ext_header was allocated on demand for allocations which have
child-allocations or destructors. In theory, it saved 2 words for every
TA leaf allocation. It had the very API-visible problem that setting a
parent or destructor could fail. (Although in most cases, the failure
was part of an allocation call anyway. Also, mpv code generally used the
early-failure variants, so it didn't matter.)
I think this was a bit too complex. These 2 words don't really matter;
if you have memory allocations where you are worried about overhead,
then these simply shouldn't use TA. Also, we never added new features to
TA that would have needed more "optional" header fields, which would
have justified the use of such a separately allocated header struct.
This uses quite straight-forward data structures. The only strange thing
is that ta_header.parent is NULL for most child allocations. That is
because we don't want to iterate over all children when the parent is
reallocated (yes, that is allowed, yes mpv makes use of it).
The new code has a few more special cases, because the list sentinel
concept isn't used anymore. Using it would have made the code more
unnatural/complex, because ta_ext_header doesn't exist anymore.
the actual character that made mpv crash is IDEOGRAPHIC COMMA
(U+3001, UTF-8: E3 80 81, 、) and that only in some specific
circumstances that could be reliably reproduced on my end.
using an NSString instead of the Swift String actually fixes that issues
even though they should technically do the exact same thing. i tested
all the other String initialisers, but they all had had the same issue.
this is kinda only a workaround till i can find a different way of
handling it.
this basically moves the remote command center to our mac events instead
of keeping it our Application, which is only available when started from
mpv itself. also make it independent of the NSApplication.
this also prevents a runtime crash
This was changed 6 years ago (444e583b6) and seemed to work fine. But it
does seem to cause issues with IceWM sometimes, while with StaticGravity
the problem is gone. Comparing both gravity values, reading the confused
source code comment, and reading the referenced commit message, I can't
determine what it even does, I just remove it.
Reproduction:
- start mpv in windowed mode, with 2 videos of different size
- switch to second video
- switch window with alt+tab
- switch back to mpv with alt+tab
- window moves to X=0
There's probably a better way to fix this. Please send a patch.
This was obviously nonsense. In Lua 5.1 this appeared to work correctly,
but it really turned "\." into "." (making the pattern accept any
character). The proper way is using "%" for escaping.
In all_formats mode, we've ignored what --ytdl-format did so far, since
we've converted the full format list, instead of just the formats
selected by youtube-dl.
But we can easily restore --ytdl-format behavior: just mark the selected
tracks as default tracks.
A parameter that is actually used is removed from the param_names[]
array, so we can report unused parameters. This also happened on
duplicate parameters, so adjust the warning to make it less confusing.
(In any case, you're not supposed to provide duplicate parameters.)
vbr and abr are the video and audio bitrates. Sometimes there is a weird
mix of any of them available, but in these cases, it's not good to fall
back to tbr if a specific track has no vbr/abr.
For example, the alphabetic site provides tbr only for the muxed
fallback stream, but using tbr would make the primitive mpv hls_bitrate
selection pick the compatibility stream for audio, because it appears to
have a higher bitrate than the other audio-only streams (because the
bitrate includes video). So we must not use tbr in this case.
On the other hand, formats coming from youtube-dl HLS master playlist
use will only have tbr set.
So as a heuristic, use the tbr only if it's the only bitrate available
in any track entry.
I don't think the skip_muxed option was overlay useful. While it was
nice to filter out the low quality muxed versions (as it happens on the
alphabetic site, I suspect it's compatibility stuff), it's not really
necessary, and just makes for another tricky and rarely used
configuration option. (This was different before muxed tracks were also
delay-loaded, and including the muxed versions slowed down loading.)
Add the force_all_formats option instead, which handles the HLS case.
Set it to true because they are also delay-loaded now, and don't slow
down startup as much.
Until now, delay-loading was for files with single tracks only
(basically what DASH and HLS like to expose, so adaptive streaming and
codec selection becomes easier - for sites, not for us). But they also
provide some interleaved versions, probably for compatibility. Until
now, we were forced to eagerly load it (making startup slightly slower).
But there is not much missing. We just need a way to provide multiple
metadata entries, and use them to represent each track.
A side effect is now that the "track_meta" header can be used for normal
EDL files too.
RTSP supports seeking, but at least the libavformat implementation makes
this dependent on runtime behavior. So you have to perform a seek, and
check if it fails. But even if you do this, the stream is interrupted
and restarted, and there seem to be other issues.
Assume that RTSP with unknown duration means it's a live stream, and
disable seeking in this case, as suggested by the issue reporter.
Fixes: #7472
Now this was stupid. To seek a source, it obviously has to be opened...
so just don't try to seek any unused source. If the track is actually
selected during playback, a seek to the correct position is performed
anyway.
These have ->segmented set (so the codec can be initialized properly),
but have no segment start or end times. This code was (probably) the
only thing which didn't handle this case.
If all streams were delay loaded, there was actually no duration present
at all in the EDL metadata. So the length was considered unknown by the
player frontend.
See manpage additions. We would have to extend delay_open to support
multiple sub-tracks (for audio and video), and we'd still don't know (?)
whether it might contain more than one stream each (thinking of HLS
master streams). And if it's a true interleaved file (such as a "normal"
mp4 file provided as fallback for more primitive players), we'd either
have to signal such "bundled" tracks, or waste bandwidth.
This restructures a lot. The if/else tree in add_single_video for format
selection was a bit annoying, so it's split into separate if blocks,
where it checks each time whether a URL was determined yet.
If a "format" has both audio and video codec set, it might contain both
audio and video. all_format assumes that each format is just a quality
variant containing a single track.
This seems to happen with sites that provide a HLS master URL.
youtube-dl tends to "butcher" it, and the result isn't very ideal. I
guess HLS "renditions" simply don't map well to youtube-dl's output
format and what mpv expects. Playing master HLS directly is also less
than ideal, because of libavformat's stupid probing.
Fix this by not using the delay-opening mechanism if it appears like we
detected such a case. Add a metadata override to set the track titles to
"muxed-N", to indicate that they form a single unit. (Mostly helpful for
testing.)
ytdl_hook.lua can do this with all_formats and when delay_open is used,
and if the source stream actually contains both audio and video. In this
case, it might accidentally hide a media type completely, or waste
bandwidth (if the stream has true interleaved audio/video). So it's
important to warn.
This is just a more convenient way to start IPC client scripts per mpv
instance.
Does not work on Windows, although it could if the subprocess and IPC
parts are implemented (and I guess .exe/.bat suffixes are required).
Also untested whether it builds on Windows. A lot of other things are
untested too, so don't complain.
Pretty worthless I guess. I only tested one site (and 2 videos), it's
somewhat likely that it will break with other sites. Even if you leave
the option disabled (the default).
Slightly related to #3548. This will allows you to use the bitrate
stream selection mechanism, that was added for HLS, with normal videos.
While paused, the decoders typically stop reading data from the demuxer.
But for some reason, the file size is returned as a public field in
struct demuxer (wat...), and updated only when the packet reading
function is called. This caused the file size property to always return
the same value when paused, even though the demuxer thread was reading
new data, and the internal file size was updated.
Fix with a simple hack.
Instead of every packet. Doing it every packet led to the performance
regression mentioned in the fstat() commit. This should now be over, but
out of being careful, don't query the file size that often. This is only
used for user interface things, so this should not cause any problems.
For the sake of leaving the code compact, abuse another thing that is
updated only every second (speed statistics).
It appears using lseek() to seek to the end and back to determine file
size is inefficient in some cases.
With CIFS, this restores the performance regression that happened when
the stream cache was removed (which called read() from a thread). This
is probably faster than the old code too, because it's the seeking that
was slowing down CIFS.
According to the user who tested this, the size caching does not help
with fstat() (although it did with the old method).
Fixes: #7408, #7152
The previous method for this sucked: for every launched detached
process, it started a thread, which then would leak if the launched
process didn't end before the player uninitialized. This was very racy
(although I bet the race condition wouldn't trigger in a 100 years), and
wasteful (threads aren't a cheap resource).
Implement it for POSIX directly. posix_spawn() has no direct support for
this, so we need to do it ourselves with fork(). We could probably do it
without fork(), and attempt to collect the PID in another thread. But
then we'd either have a waiting thread again, or we'd need to do an
unsafe waitpid(-1, ...) call. (POSIX process management sucks so badly,
how did they even manage this. Hopefully I'm just missing something, but
I'm not.) So now we depend on both posix_spawn() _and_ fork(), isn't it
fun?
Also call setsid(), to essentially detach the child process from the
terminal. (Otherwise it can receive various signals from the terminal,
which is probably not what you want.) posix_spawn() adds
POSIX_SPAWN_SETSID in newer POSIX releases, but we don't want to rely on
this yet.
The posix_spawnp() call is duplicated, but this is better than somehow
trying to unify the code paths.
Only somewhat tested, so enjoy the bugs.
Introduce mp_subprocess() and related definitions. This is a bit more
flexible than the old stuff. This may or may not be used for a more
complicated feature that involves starting processes, and which would
require more control.
Only port subprocess-posix.c to this API. The player still uses the
"old" API, so for win32 and dummy implementations, the new API is simply
not available, while for POSIX, the old APIs are emulated on top of the
new one. I'm hoping the win32 code can be ported as well, so the ifdefs
in subprocess.c can be dropped, and the player can (if convenient or
needed) use the new API.
Filters that fail to create are not supposed to do this. Generally it
should happen in process() only.
This fixes the previous commit. If a filter could not be created, it
"trashed" the wrapper filter with the failure. (Even if the wrapper were
to handle were to handle failures of sub-filter, it couldn't handle init
failure because it cannot call mp_filter_set_error_handler() before the
newly created filter is actually returned.)
Fixes: #7465 (attempt 2)
If hw decoding is used, but no hw deinterlacer is available, even though
we expect that it is present, fall back to using hw-download and yadif
anyway. Until now, it was over if the hw filter was somehow missing; for
example, yadif_cuda apparently requires a full Cuda SDK, so it can be
missing, even if nvdec is available. (Whether this particular case works
was not tested with this commit.)
Fixes: #7465
Libav seems rather dead: no release for 2 years, no new git commits in
master for almost a year (with one exception ~6 months ago). From what I
can tell, some developers resigned themselves to the horrifying idea to
post patches to ffmpeg-devel instead, while the rest of the developers
went on to greener pastures.
Libav was a better project than FFmpeg. Unfortunately, FFmpeg won,
because it managed to keep the name and website. Libav was pushed more
and more into obscurity: while there was initially a big push for Libav,
FFmpeg just remained "in place" and visible for most people. FFmpeg was
slowly draining all manpower and energy from Libav. A big part of this
was that FFmpeg stole code from Libav (regular merges of the entire
Libav git tree), making it some sort of Frankenstein mirror of Libav,
think decaying zombie with additional legs ("features") nailed to it.
"Stealing" surely is the wrong word; I'm just aping the language that
some of the FFmpeg members used to use. All that is in the past now, I'm
probably the only person left who is annoyed by this, and with this
commit I'm putting this decade long problem finally to an end. I just
thought I'd express my annoyance about this fucking shitshow one last
time.
The most intrusive change in this commit is the resample filter, which
originally used libavresample. Since the FFmpeg developer refused to
enable libavresample by default for drama reasons, and the API was
slightly different, so the filter used some big preprocessor mess to
make it compatible to libswresample. All that falls away now. The
simplification to the build system is also significant.
Works as ad-filter. I had some more plans, for example replacing
matching text with different text, but for now it's dropping matches
only. There's a big warning in the manpage that I might change
semantics. For example, I might turn it into a primitive sed.
In a sane world, you'd probably write a simple script that processes
downloaded subtitles before giving them to mpv, and avoid all this
complexity. But we don't live in a sane world, and the sooner you learn
this, the happier you will be. (But I also want to run this on muxed
subtitles.)
This is pretty straightforward. We use POSIX regexes, which are readily
available without additional pain or dependencies. This also means it's
(apparently) not available on win32 (MinGW). The regex list is because I
hate big monolithic regexes, and this makes it slightly better.
Very superficially tested.
Until now, filter_sdh was simply a function that was called by sd_ass
directly (if enabled).
I want to add another filter, so it's time to turn this into a somewhat
more general subtitle filtering infrastructure.
I pondered whether to reuse the audio/video filtering stuff - but better
not. Also, since subtitles are horrible and tend to refuse proper
abstraction, it's still messed into sd_ass, instead of working on the
dec_sub.c level. Actually mpv used to have subtitle "filters" and even
made subtitle converters part of it, but it was fairly horrible, so
don't do that again.
In addition, make runtime changes possible. Since this was supposed to
be a quick hack, I just decided to put all subtitle filter options into
a separate option group (=> simpler change notification), to manually
push the change through the playloop (like it was sort of before for OSD
options), and to recreate the sub filter chain completely in every
change. Should be good enough.
One strangeness is that due to prefetching and such, most subtitle
packets (or those some time ahead) are actually done filtering when we
change, so the user still needs to manually seek to actually refresh
everything. And since subtitle data is usually cached in ASS_Track (for
other terrible but user-friendly reasons), we also must clear the
subtitle data, but of course only on seek, since otherwise all subtitles
would just disappear. What a fucking mess, but such is life. We could
trigger a "refresh seek" to make this more automatic, but I don't feel
like it currently.
This is slightly inefficient (lots of allocations and copying), but I
decided that it doesn't matter. Could matter slightly for crazy ASS
subtitles that render with thousands of events.
Not very well tested. Still seems to work, but I didn't have many test
cases.
The example configuration uses values of true/false for the script
options. As per DOCS/man/lua.rst boolean values should be represented
with yes/no and using true/false will result in an error.
This updates the comments and changes the true/false values under the
example configuration to yes/no.
This renders incorrectly in the html output. I suspect you need one more
level here. Increase the indentation level. No other changes, other than
re-breaking some lines.
Uses the infrastructure added in the previous commits. This is
admittedly a bit weird (constructing EDL URLs and such). But on the
other hand, adding this as "first class" mechanism directly to the
sub-add command or so would increase weirdness and unexpected behavior
in other places, or at least that's what I think.
To reduce confusion, this goes through the effort of mapping the webvtt
codec, so it's shown "properly" in the codec list. Without this it would
show "null", but still work. In particular, any non-webvtt codecs should
still work if libavcodec supports it.
Not sure if I should remove the --all-subs hack from the code. But I
guess it does no harm.
This is for easier use with the "delay_open" feature added in the
previous commit. The "null" codec is reported if the codec is unknown
(because the stream was not opened yet at time the tracks were added).
The rest of the timeline mechanism will set the correct codec at
runtime. But this means every time a delay-loaded track is selected, it
wants to initialize a decoder for the "null" codec.
Accept a "null" decoder. But since FFmpeg has no such codec, and out of
my own laziness, just let it fall back to "common" codecs that need no
other initialization data.
Add something that will access an URL embedded in EDL only when the
track it corresponds to is actually selected. This is meant to help with
ytdl_hook.lua and to improve loading speeds.
In theory, all this stuff is available to any mpv user, but discourage
using it, as it's so specialized towards ytdl_hook.lua, that there's
danger we'll just break this once ytdl_hook.lua stops using it, or
similar.
Mostly untested.
Normally, the first sub-stream is implicitly created. This change lets
the user use more orthogonal syntax, and use a new_stream header for
every sub-stream, instead of having to skip the header for the first
one.
Accidentally broken by commit 99700bc52c. mp_path_join() does not
check for this, because it's supposed to work on filesystem strings (and
e.g. "http://fubar" is a valid relative path in UNIX).
Add a mp_log context to the parse_edl() function, and report some
errors. Previously, this just told you that something was wrong. Add
some error reporting to make it slightly less evil.
Put all parameters in a list before processing them. This makes adding
parameters for special headers easier, and we can report parameters that
were not understood. (For "compatibility", which probably doesn't matter
at all, still don't count them as errors; as before.)
The timeline stuff has messed up memory management because there are no
clear ownership rules between a some demuxer instances (master or
demux_timeline) and the timeline object itself.
This is another subtle problem that happened: apparently,
demux_timeline.open is supposed to take over ownership of timeline, but
only on success. If it fails, it's not supposed to free it. It didn't
follow this, which lead to a double-free if demux_timeline.open failed.
The failure path in demux.c calls both timeline_destroy() and
demux_timeline.close on failure.
Move them around in the source code to get rid of the forward
declarations. Other than rearranging the lines and removing the 2
forward declarations, there are no other changes at all.
stream_seek() might somewhat show up in the profiler, even if it's a
no-OP, because of the MP_TRACE() call. I find this annoying. Otherwise,
this should be of no consequence, and should not break or improve
anything.
Some cache logic in demux.c queries the raw byte stream size on every
packet read. This is because it reports the value to the user. (It has
to be polled like this because there is no change notification in most
underlying I/O APIs, and also the user can't just block on the demuxer
thread to update it explicitly.)
This causes a very high number of get_size calls with low packet sizes,
so cache the size, and update it on every read. Reads only happen
approximately all 64KB read with default settings, which is way less
frequent than every packet in such extreme cases.
In theory, this could in theory cause problems in some cases. Actually
this is whole commit complete non-sense, because why micro-optimize for
broken cases like patent troll codecs. I don't need to justify it
anyway.
As a minor detail, off_t is actually specified as signed, so the off_t
cast is never needed.
Resizing the window while preserving the aspect ratio actually kind of
sucked. The window size could make big dramatic changes which was pretty
unintuitive with respect to where the mouse was actually located.
Instead, let's just do some math to ensure that the window size is
always contained inside the width/height reported by
handle_toplevel_config while preserving the aspect ratio. Fixes#7426.
A previous commit moved the underrun reporting to report_underruns(),
and called it from get_space(). One reason was that I worried about
printing a log message from a "realtime" callback, so I tried to move it
out of the way. (Though there's little justification other than a bad
feeling. While an older version of the pull code tried to avoid any
mutexes at all in the callback to accommodate "requirements" from APIs
like jackaudio, we gave up on that. Nobody has complained yet.)
Simplify this and move underrun reporting back to the callback. But
instead of printing the message from there, move the message into the
playloop. Change the message slightly, because ao->log is inaccessible,
and without the log prefix (e.g. "[ao/alsa]"), some context is missing.
Fixes#7441. Just set screenrc to be equal to current_output's geometry.
Also remove some pointless/extra variables and print a warning/fallback
to screen 0 if a bad id is passed to --fs-screen.
AOs can report audio underruns, but only ao_alsa and ao_sdl (???)
currently do so. If the AO was marked as not reporting it, the cache
state was used to determine whether playback was interrupted due to slow
input.
This caused problems in some cases, such as video with very low video
frame rate: when a new frame is displayed, a new frame has to be
decoded, and since there it's so much further into the file (long frame
durations), the cache gets into an underrun state for a short moment,
even though both audio and video are playing fine. Enlarging the audio
buffer didn't help.
Fix this by making all AOs report underruns. If the AO driver does not
report underruns, fall back to using the buffer state.
pull.c behavior is slightly changed. Pull AOs are normally intended to
be used by pseudo-realtime audio APIs that fetch an audio buffer from
the API user via callback. I think it makes no sense to consider a
buffer underflow not an underrun in any situation, since we return
silence to the reader. (OK, maybe the reader could check the return
value? But let's not go there as long as there's no implementation.)
Remove the flag from ao_sdl.c, since it just worked via the generic
mechanism. Make the redundant underrun message verbose only.
push.c seems to log a redundant underflow message when resuming (because
somehow ao_play_data() is called when there's still no new data in the
buffer). But since ao_alsa does its own underrun reporting, and I only
use ao_alsa, I don't really care.
Also in all my tests, there seemed to be a rather high delay until the
underflow was logged (with audio only). I have no idea why this happened
and didn't try to debug this, but there's probably something wrong
somewhere.
This commit may cause random regressions.
See: #7440
If ao_add_events() is used, but all events flags are already set, then
we don't need to wakeup the core again.
Also, make the underrun message "exact" by avoiding the race condition
mentioned in the comment.
Avoiding redundant wakeups is not really worth the trouble, and it's
actually just a bonus in the change making the ao_underrun_event()
function return whether a new underrun was set, which is needed by the
following commit.
Obviously, we don't want to lose fractions, and the zimg active_region
fields in fact have the type double. The integer division was wrong.
Also, always set active_region.width/height. It appears zimg behavior
does not change if they're set to the normal integer values, so the
extra check to not set them in this case was worthless.
As suggested by the zimg author: active_region is not supported on
outputs (and the API returns an error), so instead scale to the "full"
surface, but adjust the source rectangle such that the cropped output
image happens to cover the correct region.
Does this even work? Since Balmer Peak doesn't work, I can't really say,
but it seems to look correct.
X11 is in fact beautiful and superior to Wayland. Instead, just state
what the problem is in most cases: software scaling. (We have
accelerated X11 rendering in vo_gpu and others.)
This was a confusing name, because 1. there's also a z_planes[] field,
and 2. it was not specific to zimg indexes.
Possibly there used to be an idea involved about supporting alpha to
non-alpha formats by discarding the alpha plane, but zimg does this now
(and zimg will correctly blend the alpha component too).
The special thing about this format is
1. mpv assigns the component ID 4 to alpha, and component IDs 2 and 3
are not present, which causes some messy details.
2. zimg always wants the alpha plane as plane 3, and plane 1 and 2 are
not present, while FFmpeg/mpv put the alpha plane as plane 1.
In theory, 2. could be avoided, since FFmpeg actually doesn't have a any
2 plane formats (alpha is either packed, or plane 3). But having to skip
"empty" planes would break expectations.
zplanes is not equivalent to the mpv plane count (actually it was always
used this way), while zimg does not really have a plane count, but does,
in this case, only use plane 0 and 3, while 2 and 3 are unused and
unset. z_planes[] (not zplanes) is now always valid for all 4 array
entries (because it uses zimg indexes), but a -1 entry means it's an
unused plane.
I wonder if these conventions taken by mpv/zimg are not just causing
extra work. Maybe component IDs should just be indexes by the "natural"
order (e.g. R-G-B-A, Y-U-V-A, Y-A), and alpha should be represented as a
field that specifies the component ID for it, or just strictly assume
that 2/4 component formats always use the last component for alpha.
We reorder the planes between mpv and zimg conventions. It turns out the
code still confused when which convention was used.
So the way it actually works is that the _only_ place where zimg order
is used is the zimg_image_buffer.plane[] array. plane_aligned[] and
zmask[] were accessed incorrectly, although I guess it rarely had a
reason to fail (plane reordering is mostly for RGB, which has planes of
all the same size).
Adjust some comments accordingly too.
The zimg wrapper "needs" these formats as intermediary when repacking
the normal gray/alpha packed format. The packed format is used by the
png decoder and encoder, and is thus interesting.
Unfortunately, mpv-only formats are a mess right now, because all the
existing code is focused around using the FFmpeg metadata for pixel
formats. This should be improved, but not now, so make the mess worse.
This commit doesn't add support for it to the zimg wrapper yet.
libzimg recently added direct alpha support and new API for it. (The API
change is rather minimal, and it turns out we can easily support old and
new zimg versions.)
This does not support _all_ alpha formats. For example, gray + alpha is
not supported yet, because my stupid design in the zimg wrapper would
require a planar gray + alpha format, while ffmpeg provides only a
packed one.
the macOS config was only used in cocoa-cb before and only included when
it was available. since this config is meant for general macOS options
and backend independent options we include it when cocoa is available.
one of the options is already used in the old cocoa backend, which broke
using it when build without swift or cocoa-cb support.
Fixes#7449
The bash completion seems to be working decently at this point, so I
feel comfortable caching the options output to improve the performance
of the completion.
The change, in an earlier commit, in format for ass to handle results
in a different number of fields to skip. Correct that so SDH filtering
works.
Should fix issue #7188
As requested I guess. It behaves quite similar to the --loop* options.
Not quite happy with the idea that 1) the option is mutated on each
operation (but at least it's consistent with --loop* and doesn't require
more properties), and 2) the ab-loop command will do nothing once all
loop iterations are done. As a concession, the OSD shows something about
"disabled".
Fixes: #7360
This is not really a changelog, but rather a list of potentially
breaking changes API- and normal users should be aware of, and to help
with migration from older mpv releases.
for reasons unknown to me the NSCursor (un)hide functions can be
completely unreliable and the cursor can have an unknown state. this
only happens on some system and wasn't able to reproduce this. it's
probably some dumb race condition that might be possible to work around,
though because of the lack of reproducibility on my end it's hard to
test.
i decided to rework the cursor hiding code yet again and make it a lot
less greedy. the cursor will now always unhide when moved and there
will never be a situation again the cursor can't be unhidden again.
on the other hand there might be edge cases now where the cursor won't
hide immediately and you have to move it slightly to make it disappear
again. this should be an acceptable tradeoff.
Fixes#6886
this creates a default log for the last mpv run when started from the
bundle. that way one can get a log of what happened even after an issue
occurred. also add a menu entry under Help to show the current log, but
only when the bundle is used.
Fixes#7396Fixes#2547
Wayland uses vo_wayland_wait_frame plus some polling with a timeout for
blocking on vsync. Here are a couple of changes that seem to be
improvements. First, the poll time is always rounded up instead of
truncated. When rendering frames longer than the standard 16.666 ms
timeout, it seems that truncating the poll time slightly early may cause
some vsync jitter spikes. Waiting longer, even if it's too long, appears
to behave better.
The second change is to use wl_display_roundtrip instead of
wl_display_dispatch_pending. wl_display_dispatch_pending dispatches all
events immediately. This is good to avoid blocking, but it's not
guaranteed to wait long enough for all events to be processed on the
display fd. The preceding wl_display_read_events routine ensures that
all events on the display fd are queued. We just need a semi-blocking
routine to dispatch them for the most reliable vsync.
wl_display_roundtrip will dispatch any events for us, but also wait for
a reply from the display server. This makes it ideal for this role. If
the compositor doesn't reply to the client something else is probably
horribly broken and wrong anyway. It's also not a permanently blocking
call like wl_display_dispatch. If there's no frame callback (i.e. the
window is hidden), then it does not dispatch any events and returns
immediately.
Directories inside ~~/scripts/ are now loaded as scripts, so don't use
it also for modules. Now there are no default module paths.
To compensate, we now try to run ~~/.init.js right after defaults.js,
so the user may extend the js init procedure via this script, e.g. for
adding default paths to mp.module_paths .
While mpv normally uses the text a key produces (as opposed to physical
key mappings), this is different with the keypad. This is for the sake
of making it possible to distinguish between these keys and the normal
number keys on the left side of a full size keyboard.
There were complaints that the keypad doesn't interact with console.lua,
so manually map them. This ignores numlock (behaves as if it's always
on), and maps KP_DEC to "." (even though it's mapped to "," on some
keyboards). The /*-+ keys produce ASCII on mpv (at least with X11) as an
inexplicable inconsistency, so there are no mappings for these.
Fixes: #7431
Due to asynchronicity, we generally can't guarantee that a video frame
matches up with other events such as playback time change exactly (since
decoding, presentation, and property update all happen at different
times). This is a complaint in the referenced bug report, where
screenshot filenames in each-frame screenshot did not use the correct
timestamp, and instead was lagging behind by 1 frame.
But in this case, synchronicity was already pretty much forced with wait
calls. The only problem was that the playback time was updated at a
later time, which results in the observed 1 frame lag. Fix this by
moving the place where the screenshot is triggered in this mode.
Normal screenshots may still have the old problem. There is no effort
made to guarantee the timestamps absolutely line up, same as with the
OSD. (If you want a guarantee, you need to use a video filter, such as
libavfilter's drawtext. These will obviously use the proper timestamp,
instead of going through the somewhat asynchronous property etc. system
in the player frontend.)
Fixes: #7433
See #7435 and related for context.
Basically, it seems that while the original vsfilter processed subtitles
like with this option set to "yes", many current players (mpc-hc
default, vlc, probably most libass users) treat them like with "no". In
the linked issue, this makes rendering severely slower, and can consume
a lot of memory (or just overflow libass memory calculations). It seems
that changing this to "no" will lead to more good than bad, especially
because newer subtitles may be authored for the "no" behavior.
Most libass users seem to use "no" exactly because they do not call
ass_set_storage_size() at all. This API was needed because the scaling
of the subtitles depends on the video size (vsfilter bugs, or
something). In addition, it's my personal opinion that rendering should
not depend on the video at all, so I like setting the default of this to
"no".
The script was set up to only call on_update when the changelist
was non-empty. However, since the size operator does not operate
on dicts, it always returned 0 (which is truthy), thus on_update
would always be called when the script-opts property changed.
When switching between having a video visible or not,
stats.lua now picks up the required formatting changes
for the cache stats page to display correctly.
The recently added feature to load scripts from a sub-directory. A
problem was that the script name was still derived from the actual
script source file that was loaded, which was always "main.lua" (or
similar), resulting in "main" as name.
Fix this by using the directory name.
One odd corner case is that you can do "--script=/path/foo////". As by
POSIX semantics, the extra "/" are ignored. However, the newly added
code strips only one separator, so mp_basename() returns "" (as it
should), and the empty name makes mp_new_client() fail in turn. I don't
really care about this, just don't do it. But mp_new_client() failure
was silent (since it normally never happens), so add at least an error
message for that, instead of being entirely silent.
There were a couple of erroneous things in the handle_toplevel_config
function. Firstly, looping through the different states was not handled
correctly. Launching a window as maximized (can happen in sway for
example) was always stuck on true and would never be set to false. Fix
this by always checking if XDG_TOPLEVEL_STATE_MAXIMIZED is found or not.
Also do a similar thing for the fullscreen state.
Additionally, there were some issues with resizing windows and
window-scale going back to old sizes. The root of this problem is that
the width and height arguments of handle_toplevel_config aren't actually
guarenteed to be the actual width and height of the surface. There are
times when mpv will set the surface size on its own (like with
window-scale) which will be unknown to the toplevel listener. To
complicate matters, there are times when we do want to use the width and
height arguments (like when resizing with the mouse).
Fix this by checking if the width and height arguments reported by
handle_toplevel_config changed from the previous call of the function.
If the value is different, then we go ahead and use them when setting
mpv's geometry. If not, then we just ignore it.
win32 is a cursed abomination which has "drive letters" at the root of
the filesystem namespace for no reason. This requires special handling
beyond tolerating the idiotic "\" path separator.
Even more cursed is the fact that a path starting with a drive letter
can be a relative path. For example, "c:billsucks" is actually a
relative path to the current working directory of the C drive. So for
example if the current working directory is "c:/windowsphone", then
"c:billsucks" would reference "c:/windowsphone/billsucks".
You should realize that win32 is a ridiculous satanic trash fire by the
point you realize that win32 has at least 26 current working
directories, one for each drive letter.
Anyway, the actual problem is that mpv's mp_path_join() function would
return a relative path if an absolute relative path is joined with a
drive-relative path. This should never happen; I bet it breaks a lot of
assumptions (maybe even some security or safety relevant ones, but
probably not).
Since relative drive paths are such a fucked up shit idea, don't try to
support them "properly", and just solve the problem at hand. The
solution produces a path that should be invalid on win32.
Joining two relative paths still behaves the same; this is probably OK
(maybe).
The change isn't very minimal due to me rewriting parts of it without
strict need, but I don't care.
Note that the Python os.path.join() function (after which the mpv
function was apparently modeled) has the same problem.
It appears Lua's package paths try to load .lua files from the current
working directory. Not only that, but also shared libraries.
WHAT THE FUCK IS WHOEVER IS RESPONSIBLE FOR THIS FUCKING DOING?
mpv isn't setting this package path; currently it's only extending it.
In any sane world, this wouldn't be a default. Most programs use
essentially random working directories and don't change it.
I cannot comprehend what bullshit about "convenience" or whatever made
them do something this broken and dangerous. Thousands of programs using
Lua out there will try to randomly load random code from random
directories.
In mpv's case, this is so security relevant, because mpv is normally
used from the command line, and you will most likely actually change
into your media directory or whatever with the shell, and play a file
from there. No, you don't want to load a (probably downloaded) shared
library from this directory if a script try to load a system lib with
the same name or so.
I'm not sure why LUA_PATH_DEFAULT in luaconf.h (both upstream and the
Debian version) put "./?.lua" at the end, but in any case, trying to
load a module that doesn't exist nicely lists all package paths in
order, and confirms it tries to load files from the working directory
first (anyone can try this). Even if it didn't, this would be
problematic at best.
Note that scripts are _not_ sandboxed. They're allowed to load system
libraries, which is also why we want to keep the non-idiotic parts of
the package paths.
Attempt to fix this by filtering out relative paths. This is a bit
fragile and not very great for something security related, but probably
the best we can do without having to make assumptions about the target
system file system layout. Also, someone else can fix this for Windows.
Also replace ":" with ";" (for the extra path). On a side note, this
extra path addition is just in this function out of laziness, since
I'd rather not have 2 functions with edit the package path.
mpv in default configuration (i.e. no external scripts) is probably not
affected. All builtin scripts only "require" preloaded modules, which,
in a stroke of genius by the Lua developers, are highest priority in the
load order. Otherwise, enjoy your semi-remote code execution bug.
Completely unrelated this, I'm open for scripting languages and
especially implementations which are all around better than Lua, and are
suited for low footprint embedding.
This simply didn't set the direction flag in most situations, which
meant the timestamps used in the subtitle renderer were nonsense,
leading to invisible subtitles.
This works only for text subtitles that are cached in the ASS_Track
state. Reading new subtitles is broken because the demuxer layer has
trouble returning subtitle packets backwards, and I think for rendering
bitmap subtitles, the pruning direction would have to be adjusted. (Not
sure if reversing the timestamps before the subtitle renderer backend is
even the right thing to do. At least for sd_ass.c, it seems to make
sense, because it caches subtitles with "normal" timestamps.)
Apparently such .cue files exist. They fail both probing and parsing. To
make it worse, the sample at hand was encoded as Latin1.
One part of this is replacing bstr_lstrip() with a version that supports
NBSP. One could argue that bstr_lstrip() should always do this, but I
don't want to overdo it. There are many more unicode abomination which
it could be said it's supposed to handle, so it will stay ASCII instead
of going down this rabbit hole. I'm just assuming this cue sheet was
generated by some stupid software that inexplicably liked NBSPs (which
is how we justify a one-off fix). The new lstrip_whitespace() doesn't
look particularly efficient, but it doesn't have to be.
The second part is dealing with the fact that the charset is not
necessarily UTF-8. We don't want to do conversion before probing thinks
it knows it's a cue sheet (would probably make it more fragile all
around), so just make it work with Latin1 by assuming invalid code
points are Latin1. This fallback is part of why lstrip_whitespace() is
sort of roundabout.
(You could still rewrite it as much more efficient state machine,
instead of using a slow and validating UTF-8 parser that is called per
codepoint. Starting to overthink this.)
Multimedia is terrible. Legacy charsets are terrible. Everything is
terrible.
Fixes: #7429
Unfortunately, libarchive detects a stream of 0s as tar, as demonstrated
by "mpv /dev/zero". This is inconvenient in some cases.
One example is the .cue demuxer trying to open a raw audio .bin file,
which it allows only if probing fails (as .bin is raw and normally will
not look like any real file format). Although this use-case is
worthless.
On some platforms the ZPOS property might exist, but be immutable.
This is at least the case on Intel Sandy Bridge since Linux kernel
5.5.0. Trying to set an immutable property will cause.
drmModeAtomicCommit to fail with -EINVAL.
On other platforms we might want to set ZPOS to tweak the layering of
planes.
To reconcile these two, simply have drm_object_set_property check if a
property is immutable before attempting to add it to the atomic
commit, instead returning an error code (which is, as previously,
ignored in the case of ZPOS as we don't strictly need it)
The cdio API always reads in sectors (fixed CDIO_CD_FRAMESIZE_RAW
blocks). In the past, mpv/MPlayer streams had a way for a stream to
signal a sector size, so the stream's fill_buffer implementation could
ignore the length argument. Later, that was removed, but stream_cdda.c
was left with assuming that the read size was always larger than the
sector size (rightfully at the time). Even later, this assumption was
broken with commit f37f4de, when it was suddenly possibly that smaller
reads were performed (at ring buffer boundaries). It returned EOF if the
buffer size was too small, so playback stopped very early.
Fix this by explicitly handling arbitrary sizes.
Tested with a .cue/.bin file only.
Fixes: #7384
The intention is to provide a slightly nicer way to distribute scripts.
For example, you could put multiple source files into the directory, and
then import them from the actual script file (this is still
unimplemented).
At first I wanted to require a config file (because you need to know at
least which scripting backend it should use). This wouldn't have been
too hard (could have reused/abused the mpv config file parsing
mechanism, and I already had working code that was just 2 function
calls). But probably better to do this without new config files, because
it might become a pain in the distant future.
So this just probes for "main.lua", "main.js", etc., until an existing
file is found.
Another important change is that this skips all directory entries whose
name starts with ".". This automatically excludes the "." and ".."
special directories, and is probably useful to exclude random crap that
might be lying around in the directory (such as editor temporary files,
or OSX, in its usual hrmful, annoying, and idiotic modus operandi,
sharting all over any directories opened by "Finder").
Although the changelog mentions the docs, they're added only in a later
commit.
This originally existed as a hack for weston. In certain scenarios, a
frame taking too long to render would cause vo_wayland_wait_frame to
timeout which would result in a ton of dropped frames. The naive
solution was to just to add a slight delay to the time value. If a
frame took too long, it would likely to fall under the timeout value and
all was well. This was exposed to the user since the default delay
(1000) was completely arbitrary.
However with presentation time, this doesn't appear to be neccesary.
Fresh frames that take longer than the display's refresh rate (16.666 ms
in most cases) behave well in Weston. In the other two main compositors
without presentation time (GNOME and Plasma), they also do not
experience any ill effects. It's better not to overcomplicate things, so
this "feature" can be removed now.
This is a central lock (that is to stay and has no reason to go away),
and it was simply made global. This reduces complexity when the original
MPlayer code was changed from single thread + global state to a context
handle.
Having the global lock was still a bit silly if there were multiple mpv
instances in the process, because it would make the instances wait for
each other for no reason. So move it to the per-instance context, which
is trivial enough.
The wakeup_log_file callback was still assuming that mp_msg_lock was
used to control the log file thread, but this changed while I was
writing this code, and forgot to update it. (It doesn't change any
state, which is untypical for condition variable usage. The state that
is changed is protected by another lock instead. But log_file_lock still
needs to be acquired to ensure the signal isn't sent while the thread is
right before the pthread_cond_wait() call, when the lock is held, but
the signal would still be lost.)
Because the buffer's wakeup callback now acquires the lock, the wakeup
callback must be called outside of the buffer lock, to keep the lock
order (log_file_lock > mp_log_buffer.lock). Fortunately, the wakeup
callback is immutable, or we would have needed another dumb leaf lock.
mp_msg_has_log_file() made a similar outdated assumption. But now access
to the log_file field is much trickier; just define that it's only to be
called from the thread that manages the msg state. (The calling code
could also just check whether the log-file option changed instead, but
currently that would be slightly more messy.)
Until now --log-file performed a blocking write to the log file, which
made any calling thread block for I/O. It even explicitly flushed after
every line (to make it tail-able, or to ensure a hard crash wouldn't
lose any of the output). This wasn't so good, because it could cause
real playback problems, which made it infeasible to enable it by
default.
Try to buffer it through a ring buffer and a thread. There's no other
choice but to use a thread, since async I/O on files is generally a big
and unportable pain. (We very much prefer portable pain.) Fortunately,
there's already a ring buffer (mp_log_buffer, normally for the client
API logging hook). This still involves some pretty messy locking. Give
each mp_log_buffer its own lock to make this easier.
This still makes calling threads block if the log buffer is full (unlike
with client API log buffers, which just drop messages). I don't want log
messages to get lost for this purpose. This also made locking pretty
complicated (without it, mp_log_buffer wouldn't have needed its own
lock). Maybe I'll remove this blocking again when it turns out to be
nonsense.
(We could avoid wasting an entire thread by "reusing" some other thread.
E.g. pick some otherwise not real time thread, and make it react to the
log buffer's wakeup callback. But let's not. It's complicated to abuse
random threads for this. It'd also raise locking complexity, because we
still want it to block on a full buffer.)
There wasn't really much of a reason to keep split_opt and
splot_opt_silent apart. It made sense before the latter also had a log
call (which was silenced by using mp_null_log if necessary).
Just merge them back into one, and always rely on mp_null_log to silence
unwanted output.
Shouldn't have any functional changes.
Add support for setting window-minimized and window-maximized in
Windows. The minimized and maximized state can be set independently.
When the window is minimized, the value of window-maximized will
determine whether the window is restored to the maximized state or not.
Changing state is done with ShowWindow(), which has commands that change
the window state and activate it (eg. SW_RESTORE) and commands that
change the window state without activating it (eg. SW_SHOWNOACTIVATE.)
It would be nice if we could use commands that don't activate the
window, so scripts could change the window state in the backrgound
without bringing it to the foreground, but there are some problems with
that. There is no command to maximize a window without activating it, so
SW_MAXIMIZE is used instead. Also, restoring a window from minimize
without activating it seems buggy. On my Windows 10 1909 PC, it always
moves the window to the back of the z-order. SW_RESTORE is used instead
of SW_SHOWNOACTIVATE because of this.
This also changes the way the window is initially shown. Previously, the
window was made visible as a consequence of the SWP_SHOWWINDOW flag in
the first call to SetWindowPos. In order to set the initial minimized or
maximized state of the window, the window is shown with the ShowWindow
function instead, where the ShowWindow command is determined by whether
the window should be initially maximized or minimized.
Even when showing the window normally, we should still call ShowWindow
with the SW_SHOW command instead of using SetWindowPos, since the first
call a process makes to ShowWindow(SW_SHOW) has special behaviour
where it uses the show command in the process' STARTUPINFO instead of
the command passed to the function, which should fix#5724.
Note: While changes to window-minimized while in fullscreen mode should
work as expected, changing window-maximized while in fullscreen does not
work and won't result in the window changing state, even after leaving
fullscreen. For this to work correctly, the fullscreen logic needs to be
changed to apply the new maximized state on leaving fullscreen.

I noticed an oversight when using ytdl-hook -- if the path is a URL, we
try to `stat()` it, which obviously doesn't work. To mitigate that,
don't check or update mtimes for URLs.

This reverts commit 1b0129c414.
It turns out most of the files affected by the idiotic use-case actually
use this old naming pattern, which I hoped was unused.
This means for now we'll always assume .rar files are multi-part (until
proven otherwise), but the following commit tries to fix this.
It's ridiculous that --script=something.dumb does not cause an error.
Make it error, and extend this behavior to the scripts/ sub-dir in the
mpv config dir.
I think there was a user complaint that this does not restore the
playlist position.
There's no reason not to save the "state" for unseekable streams; what
we probably don't want is to make restoring trying to issue a seek. So
just don't save the position. (Although we probably could anyway, since
seek requests on unseekable streams are ignored now.)
Fixes: issue number forgotten, if it even exists.
This was used to convert e.g. P010 to NV12 within the filter chain,
which hopefully a thing that is not needed anymore. (And has been dead
code since the ANGLE "RGB" interop code was removed.)
Notably, BGR0, which is the only additional format listed as supported
by the texture mapper, results in broken colors. This is most likely not
a mpv issue, so the whitelist fulfils its purpose.
As documented on struct mp_hwdec_ctx, hw_imgfmt specifies the hardware
surface wrapper format for which supported_formats is valid. If this was
not set, f_hwtransfer ignored supported_formats, and assumed all formats
were supported.
Cache display updates, especially when it's bigger than few minute,
could have been be very infrequent to the point that one is not sure
if it updates at all.
Reduce the 10% change-threshold to 5% and add another threshold of 5s.
Right now we are generating the fully option list before doing
anything else. That makes filename completion significantly slower
than it was before, for no gain. It's easy to only generate the
option list when it's actually needed.
I also know I could additionally cache the option list across
invocations, but I'm not doing that yet to make testing easier.
There are two improvements here:
1) Correct the right-side padding on the title box. This was messed
up previously because I was passing the title box width when I
should be passing the x coordinate. I've also increased the
spacing to separate the title from the window controls more
clearly.
2) I'ved added a mouse tracking area over the title bar so that the
osc doesn't disappear if you hover over the title box. This didn't
work previously because the input area only covers the actual
window controls. The implementation here is simplified in that
it's only a mouse area and not an input area. This is enough to
keep the osc visible, but it won't stop the mouse pointer
disappearing. Fixing that requires a full input area which, for
now, I will say isn't worth the effort.
It's a bit unintuitive today when you use the un-maximise control
while fullscreened. Depending on the VO in use, this might silently
change the maximise state without any visible effect, or it might
do nothing. It's less surprising if the control exits the fullscreen
state.
Note that the exact behaviour is still VO dependent. If the window
was maximised before being fullscreened, it might exit fullscreen
back to maximised or back to regular window mode.
I thought about trying to explicitly control that behaviour but
it makes the osc code weird and probably wouldn't work all the time.
Allow the --window-maximized and --window-minimized flags to actually
work when the player is started on wayland. If the compositor doesn't
support maximization or minimization, then these options just do
nothing.
Fixes#7345
There was a multitude of issues with cursor handling in wayland and
behavior seemed to vary for strange reasons across compositors and also
bad things were being done in wayland_common. The problem is complicated
and involved fullscreen states being set incorrectly under certain
instances and so on. The best solution is to just remove most of the
extra cruft. In handle_toplevel_config, instead of automatically
assuming is_fullscreen and is_maximized are false, we should use
whatever value is currently set vo_opts which matters when we initially
launch the window.
I think the previous code didn't consider the situation if the input
format was not any of the upload formats. It then could have possibly
tried to upload the wrong format (and not sure what the underlying APIs
do with it).
Take care of this, also improve logging, and change it such that
mp_hwupload_find_upload_format() does not unnecessarily change the state
(although it doesn't really matter).
With the recent change how f_hwtransfer could select formats, it's
possible that the upload_fmts list contains formats that are never
selected, and the filter would have failed.
The way it works now is that f_hwtransfer gets to select the format
(which honestly doesn't make sense, but whatever), and f_autoconvert
gets only a single format.
It would be more ideal if f_hwtransfer provided a list of possible input
formats, but that's absurdly too complex for now. Maybe I'll change it
back at some later point, but I expect this shit to be in a perpetual
state of complexity and brokenness.
Some complex commands (like commands generated by scripts to define key
bindings or the OSD overlay command) contain new lines, which "corrupts"
logging.
Fix this by escaping the parameters C-style. Abuse the JSON writer for
this, which already has code to vaguely produce C-style escapes.
At first I considered stripping the quotes, but then I thought it's
actually a good idea to leave them in, as it makes things clearer.
Follows an idea by avih.
(Oh yes, we could have skipped all the complexity, and hardcoded the
cases that work in the first place. This wouldn't be an issue if FFmpeg
or libva exported correct information. Also possible that FFmpeg's
filter chain does not allow to do this correctly in the first place,
since filters expose next to no meta information about what hw formats
etc. they need.)
Note that uploading yuv420p to a nv12 vaapi surface actually works, but
the blacklist excludes it. So this might get a bit slower. I'm not
bothering with this case because it's rarely needed, and the blacklist
specification would become a bit more complex if you had to specify
sw/upload format pairs.
Fixes: #7350
Basically, instead of trusting the upload format, and picking the first
sw format that has a desired upload format, trust the sw format. So now
we pick the sw format first, and then select from the set of upload
formats supported by it.
This is probably more straightforward, and works around a crash with
vaapi:
mpv 8bit.mkv --vf=format=vaapi --gpu-hwdec-interop=all
(Forces vaapi upload if hw decoding is not enabled.)
Unfortunately, this still does not work, because vaapi, FFmpeg, the VO
interop code, or all of them are doing something stupid. In particular,
this picks the yuv420p sw format, which doesn't really exist despiter
advertised (???????????????????????????????????????), and simply breaks.
See: #7350
hwdec_vaapi tries to probe all available surface formats in advance. For
that, we iterate over _all_ profiles in an attempt to collect possible
surface formats. This means we try profiles we normally wouldn't use for
decoding or filtering, and which could be "unrelated" services.
It seems some drivers report at least one profile, for which
vaQueryConfigEntrypoints() fails (because the profile is not supported;
not sure why it lists it, then). So turn the error message into a
verbose message to avoid confusing output.
Fixes: #7347
This shouldn't really matter, but it's probably best to avoid.
vo_wayland_control would execute set_cursor_visibility while wl->pointer
existed but it didn't check if wl->pointer_id existed. So
wl_pointer_set_cursor would be set to a null surface with an id of 0.
Instead, just wait until we have an actual, non-zero pointer id so that
the cursor is set with the correct, actual id and not a fictious 0 id.
This ensures that the pointer isn't set until it enters the wl_surface
which is what we want.
While we've had a zsh completion script for a while, we haven't had
one for bash. This one is reasonably comprehensive, although there are
improvements one could imagine for certain options.
at the time of the initial dpi query the window is not instantiated yet.
we use a proper fallback in that case, eg the target configured screen
or the main screen if none is set.
also change some weird oversight and a small optimisation.
don't build our own ffmpeg anymore and instead use the bottled version
from homebrew. update the newest macOS image. also handle macOS 10.12
as a legacy OS since homebrew and Apple stopped supporting it.
nevertheless it's helpful to build on that version since it's the last
version we support building on. it's a bit special since we have to pin
the homebrew-core version to a previous one where all the bottles for
macOS 10.12 are still available, otherwise it would build nearly
everything from source and that would take ages. also start caching the
homebrew cache folder for downloads.
This code assumed that the function is only called from the playloop
itself (and since property notification is done at the end of it, i.e.
before sleeping, it obviously would not have needed to wake up the
core).
But this function is actually called from some comments (such as
playlist-move), so this assumption was incorrect. Use the same method as
the other function.
Untested.
Fixes: #7339 (probably)
Seems like I'm still not done with rar playback stuff...
It turns out the reason for archive_read_open1() opening all volumes had
nothing to do with libarchive's rar code, but was a consequence of how
multi volume support is implemented in libarchive, and due to the fact
that we enabled archive_read_support_format_zip_seekable() (through
archive_read_support_format_zip()).
The seekable zip format will seek to the end of the file and search for
a zip "header" there. It could possibly be considered a libarchive bug
that it does that even if it's fairly sure that it's a RAR file.
We already do probing on a small buffer read from the start of the file
(i.e. not giving libarchive a way to seek the stream before we think
it's an archive), but that does not help, since libarchive needs to
probe _again_. libarchive does not seem to provide a function to query
the format (no archive_read_get_format()). Which seems quite strange,
but at least I didn't find one.
This commit works this around by doing some manual rar/zip probing. We
could have gone only with rar probing. But detecting zip separately
allows us to avoid that stream_libarchive seeks to the end during early
probing. This is an additional bonus on top of "fixing" multi volume
rar.
The zip probing is from archive_read_format_zip_streamable_bid(). The
rar signature is the common prefix of the rar and rar5 formats in
libarchive (presumably the RAR fixed header parts without version).
If the demuxer seeks to the end of the rar entry, this will still open
all volumes; I'm not sure whether the old/removed rar code in mpv could
handle this better.
See: #7182
This matches lua's 11b9315b but with the lagacy field names which the
js code used previously.
Currently the property always returns an object (with dummy/last/null
field values if there are no dimensions), but the code is ready for
a future case where it might return null if there are no dimensions - at
which case it will forward the null, breaking backward compatibility for
a better API.
Theoretically possible (and quite unlikely due to the small texture
size). The code was originally written with the assumption that texture
allocations can't fail, and it was never updated out of laziness.
Untested.
The idea is that if the player is resized, we do not delay redrawing
(which is normally done to limit the redraw rate to something
reasonable).
Not sure if this even does anything. For one, reacting to osd-dimensions
changes is cleaner than just polling the screen size with the next tick
event, and hoping that resizes generate tick events for whatever
logically unrelated reasons.
check_obj_resize() in sub/osd.c calls mp_client_broadcast_event(), which
calls notify_property_events(). This is pretty unexpected, because
check_obj_resize() may be called from the VO thread. While that's sort
of awful, it seems to be OK locking-wise. But it breaks an assumption in
notify_property_events() that the core doesn't need to be woken up,
which could possibly lead to a missed/delayed property update (although
rather unlikely).
Fix this by explicitly waking up the core when it's called from the OSD
code.
This is a gross hack for the shitty design of how VO properties are
handled (which was fine with MPlayer, but became increasingly a shit tub
with mpv's VO thread).
The problem here is that console.lua reads display-hidpi-scale on every
render, but which may take a long time for video timing and vsync
blocking. It will also block the core, making osc.lua unable to react to
window resizing quickly enough.
This should be solved by not using the "classic" blocking VOCTRL
mechanism, and instead side-stepping it with something that doesn't
require any waiting (like for example the "fullscreen" property does).
But this require more thinking and work my "brain" can handle at the
moment. So for now add a shitty hack that will cause a lot of problems,
and which will have to be replaced later. Most importantly, it'll break
theoretic support for multiple screens with different DPI, or runtime
DPI changes. Possibly could affect the Cocoa backend; the X11 isn't
dynamic enough by nature, and other backends do not implement this.
See previous commit.
A nice side-effect is that mp.get_osd_margins() is not a special
Lua-only thing anymore. I didn't test whether this function still works
as expected, though.
This "bundles" all OSD properties. It also makes some previously
Lua-only values available (Lua has mp.get_osd_margins(), unsure if
anything uses it).
The main intention is actually to allow retrieving all fields in an
"atomic" way. (Could introduce a mechanism on the level of the mpv
client API to do this, but doing ti ad-hoc all the time like this commit
is easier.)
Addresses dumb things like accidentally overwriting a media file with
e.g. "mpv --log-file test.mkv" (when the user thought that --log-file
was a flag option, when it actually takes a filename). This example will
now print an error. It still works with "-log-file overwritten.mkv", but
prints a warning.
Not sure if I'm being too careful or not "radical" enough. In any case,
both the syntax that stops working and the syntax that produces a
warning now have been discouraged and were called legacy for almost a
decade.
Well that was too much misery when trying to deal with an idiotic
feature, so it had to be compensated for.
Replace insults with proper explanation, libarchive sort of isn't guilty
in the first place, and their format support is pretty good all things
considered.
The change was not propagated to the OSD/subtitle code, since that still
uses an "old" method. Change it so that the propagation is actually
performed.
(One could argue the OSD/subtitle code should use other ways to update
the options, but that would probably be more effort for now.)
This turned every "normal" .rar filename into a multi-volume one
accidentally. Since the detection is purely by filename (due to lack of
support by libarchive I guess), it causes the nasty message added in the
previous commit to appear for every .rar file. Just drop it.
See manpage additions. The libarchive behavior mentioned in the last
paragraph there is technically unrelated, but makes this new option
mostly pointless.
See: #7182
Until now, they were all just added to options.c (e.g. demux_mkv_conf).
This adds a mechanism which can be used to add future options in a
(very) slightly more elegant way.
There are a lot of ad-hoc component lists in mpv: for example the stream
and demuxer lists. It doesn't seem to make sense to add any abstractions
around it since they are completely trivial and have very specific
probing mechanisms and so on, so they will remain ad-hoc.
This commits add a way to let these add arbitrary per-component options,
without giving up the ad-hoc way, and without having to dump them into
options.c with lots of ifdeffery (like it was done until now).
Also see next commit.
Instead of opening every volume on start just to see if it's there, all
all volumes that could possibly exist, and "handle" it on opening. This
requires working around some of libarchive's amazing stupidity and using
some empirically determined behavior. Will possibly break if libarchive
changes some of this behavior.
See: #7182
We whitelist formats (and not all of them). RAR v5 is a separated format
entry for inexplicable reasons. (It's a separate implementation, but who
really wants to support only either of the rar formats?)
I'm not sure if it was libarchive 3.3.3. Their git history is absolutely
chaotic. These people do not know how to use git. I couldn't be bothered
to dig deeper.
Currently, the activation and deactivation of input handling is done
inside the render() loop, but this does not run when the osc mode is
`never` - which does make sense.
That means that if you are cycling the visibility mode, the input
state will be whatever it was at the time of the mode change. And,
as our modes are ordered `auto` -> `always` -> `never`, the input
state will be enabled when you cycle to `never`.
There are various ways you can imagine fixing this, and in this
change I propose we reset the input state to disabled on a mode
change, and then let render() re-enable input if that's appropriate.
Fixes#7298.
It turns out that gnome wayland still has very serious issues that make
it unusable for playback with mpv. Other compositors mostly behave fine
(Plasma is just missing feature but it's not seriously broken), so GNOME
gets the special honor of having a warning printed out. The only
solution for GNOME users at this time of writing is to either use the
Xorg session or use another wayland compositor.
When switching tracks, the data for the new track is missing by the
amount of data prefetched. This is because all demuxers return
interleaved data, and you can't just seek the switched track alone.
Normally, this would mean that the new track simply gets no data for a
while (e.g. silence if it's an audio track). To avoid this, mpv performs
a special "refresh seek" in the demuxer, which tries to resume demuxing
from an earlier position, in a way that does not disrupt decoding for
the non-changed tracks. (Could write a lot about the reasons for doing
something so relatively complex, and the alternatives and their
weaknesses, but let's not.)
This requires that the demuxer can tell whether a packet after a seek
was before or after a previously demuxed packet, sort of like an unique
ID. The code can use the byte position (pos) and the DTS for this. The
DTS is normally strictly monotonically increasing, the position in most
sane file formats too (notably not mp4, in theory).
The file at hand had DTS==NOPTS packets (which is fine, usually this
happens when PTS can be used instead, but the demux.c code structure
doesn't make it easy to use this), and pos==-1 at the same time. The
latter is what libavformat likes to return when the packet was produced
by a "parser" (or in other words, packets were split or reassembled),
and the packet has no real file position. That means the refresh seek
mechanism has no packet position and can't work.
Fix this by making up a pseudo-position if it's missing. This needs to
set the same value every time, which is why it does not work for
keyframe packets (which, by definition, could be a seek target).
Fixes: #7306 (sort of)
When using --keep-open, and the end of the file is reached, the player's
"pause" property is set to true. Attempting to set it to false reverts
it back to true immediately. That's how it's designed, for better or
worse.
Running "seek -10 ; set pause no" did not work, because the seek is
first queued and pause is unset, but then the decoding functions
determine that EOF is still a thing, and "mpctx->stop_play =
AT_END_OF_FILE;" is set again. handle_keep_open() then sets pause again.
Only then the seek is actually run.
Fix this by not setting stop_play if a seek is queued.
In the distant past, the cuviddec backed copy hwaccel could be
configured directly using lavc options. However, since that time,
we gained support for automatic hw ctx creation which ended up
bypassing the lavc options.
Rather than trying to find a way to pass those options again, a
better idea is to make the 'cuda-decode-device' option, used by
the interop hwaccels, work for the copy hwaccels too.
And that's pretty simple: we have to add a create function that
checks the option and passes it on to ffmpeg.
Note that this does require a slight re-jig to the configuration
flags, as we now have a scenario where we want to build with support
for the cuda copy hwaccels but not the interop ones. So we need
a distinct configuration flag for that combination.
Fixes#7295.
In vaapi 1.1.0 (which confusingly is libva release 2.1.0), they
introduced a new surface export API that is more efficient, and
we've been supporting that and the old API ever since (Feb 2018).
If we drop support for the old API, we can do some fairly nice cleanup
of the code.
Note that the pkgconfig entries are explicitly versioned by the API
version and not the library version. I confirmed the upstream pkgconfig
files.
As we are less and less interested in vpdpau, with nvdec and vaapi
being better choices in general on nvidia and AMD respectively, we
might consider removing direct_mode, where we bypass the vdpau
mixer and work directly with yuv textures. Normally, working with
yuv textures would be great, but vdpau built in an assumption that
all frames are delivered as separate fields, causing us to have
to re-interleave them.
nvidia then introduces a new OpenGL extension that can return the
yuv frames as frames, but we can't just unconditionally switch to
that as we'd want to keep supporting older hardware where the drivers
are no longer getting new features. The end result is that we
wouldn't be able to get rid of the old code paths.
Removing direct_mode means we always use the mixer, and work with
rgba frame textures. There are some theoretical limitations to
this, but in practice they probably don't matter much - unsupported
colourspaces don't matter because without 10bit decoding support,
we can't use them anyway, and apparently we're not doing separate
chroma scaling these days, so scaling the rbga doesn't really lose
anything (and the vdpau hq scaling option remains available).
Although a linked list was ideal at first, there are cases where it
sucks, and became increasingly awkward (with the mpv command API
preferring integer indexes to access the list). In future, we probably
want to add more playlist-related functionality, so better change it to
an array now.
An array isn't always ideal either. Since playlist entries are still
separate objects (because in some cases you need a stable "iterator" to
it), but you still need to efficiently get the next/previous playlist
entry, there's a pl_index field, that needs to be maintained. E.g.
adding an entry at the start of the playlist => update the pl_index
field for all other entries. Well, it's not really worth to do something
more complicated to avoid these things.
This commit is probably buggy as shit. It's not like I bothered to test
everything. That's _your_ role.
GCC 9.2 warns about this. It was always a bit sketchy, so get rid of it.
VK_F10 generates WM_SYSKEYDOWN, so it only needs to be handled in the
WM_SYSKEYDOWN case.
