Allows to specify custom fontconfig sysroot. Useful for fuzzing
environments where we might use specific config, font or the system wide
config is not available.
We want to add padding around the whole bitmap, not within it. Smaller
parts are rendered onto bigger bitmap. Remove leftover padding code.
Fixes: e2fc75434e
This ensures that we don't mix maxCLL if target already has max_luma.
This can be opt-in with mode=source and manual target-peak override. No
need to merge to much things.
We wait for timeout and stop fuzzing, but if there are events spammed
this timeout never fire, so instead limit the number of events after
playback reset.
This is raw option passed to lavf and can be used to inject complex
filters and so on, avoid this for fuzzing as it more fuzzing ffmpeg side
anyway and causes issues with timeouts for some big processing.
Useful for demux_edl where it is possible to have huge nested tree of
demuxers and they are added recursively, which causes stack overflow in
some cases.
Found by OSS-Fuzz.
Also cache last dxgi output, to avoid enumerating outputs, this is done
on every frame and we want to minimize impact of it.
While at it refactor and split loading libraries.
Instead of using IDXGISwapChain::GetContainingOutput create new DXGI
interface on each query. This may not be as efficient, but it solves the
issue where metadata is not updated after changing display settings.
DXGI caches parameters on swapchain creation and never updates it.
Also refactor it so it can be used from other contexts.
Note that DXGI is not D3D11, it's mixed in mpv code, may be cleaned in
the future.
If color space hint is enabled respect configured parameters of
swapchain. When color space hint is disabled, override output freely.
This fixes possible fallback or other decisions about output made during
the swapchain color space negotiation.
When targeting SDR on display with enabled HDR, compositor will have to
convert SDR to HDR transfer before sending this to display. Resulting in
most certainly wrong output.
To avoid this always convert SDR to target transfer function when
hinting, this way, we do the conversion in mpv and not defer it down the
pipeline.
Unfortunately it's not very portable to detect if we have HDR display
output and "guess" if what we send to display will be correctly
interpreted or not. But we do this when we can.
Also don't force target_peak value from auto detection, use value from
libplacebo.
While testing larger inputs can be useful for uncovering bugs related to
processing large data or inefficiencies in memory allocation, it also
makes the fuzzing process slower and more fragile.
Beyond the obvious slowdown, there are OOM issues and even in libFuzzer.
Specifically, in fuzzer::InputCorpus::AddToCorpus, after a few hours of
fuzzing, we accumulate so many inputs that memory usage exceeds our
quota. This could be mitigated in other ways, such as dumping data early
or shortening the fuzzing run duration. However, in practice, these huge
inputs are often not very useful.
This change will also encourage the fuzzer to mutate existing data
rather than continually adding more bytes to input, because it give
higher coverage. Which in turn will produce higher quality corpus.
The 100 KiB limit could be reduced further. It's still quite large, let's
see how it performs. I believe even 10 KiB might be sufficient or less.
This issue is especially noticeable in the Matroska fuzzer, because we
add input data there, which is bigger and sets max_len high in fuzzer
itself.
In a perfect world, we wouldn't need to impose such limits, but in
reality, we face constraints in both memory and compute resources.
I'll monitor coverage and fuzzing results after this change and adjust
as needed. Unfortunately, this will discard all existing corpus entries
larger than the limit, but that's expected.
Most users of this function doesn't expect it to return NULL, with
exception of Stereo-3D video mode. Which is a list directly linked to
Matroska specification, and used as value check in demux_mkv and also
when printing format.
There already was a MP_STEREO3D_NAME_DEF macro, so just promote this to
more generic function.
Fixes assert on invalid value found by OSS-Fuzz.
Fixes double evaluation in MP_STEREO3D_NAME_DEF macro.
Rendering OSD on every frame draw is quite heavy, even if some of the
rendering parts are cached, it still takes significant amount of time,
depending of payload can take 8-10 ms just to do the text shaping.
Instead render only when we need it.
Drop it to warning, even if -Werror is in effect. Interesting part is
that this makes this warning disappear completely. GCC diagnostics at
its finest.
sizeof(AVPacket) being part of an ABI is deprecated. This was the last
remaining stack usage, missed in previous related change.
Note that we still use sizeof(AVPacket) and sizeof(AVBufferRef) in
demux_packet_estimate_total_size(). But it's safe, the worse that can
happen is that we underestimate the size on mismatch.
Fixes: cb15bc4324
Fixes excessive memory usage with avdevice input. After [1] packets
returned from avdevice contains wrapped AVFrame. mpv estimates packet
size to limit how many of them are cached. The size were not correctly
calculated, because packed contained only AVFrame* and not the actual
data in buffer. Fix this by calculating wrapped size and add it to our
size estimation.

Disables perf graphs from stats.lua. They are relatively expensive to
render, causes a lot of memory to be used for caches which are never
reused because graph is rarely the same. And most importantly those
graphs are not that useful beyond quick visual inspection of jitter.
Can be enable in script-opt if needed. Cache graph is left enabled,
because it shows if cache readhead grows or not nicely.
If Vulkan hwdec is exposed by the system, use this as it provides better
compatibility with native Vulkan rendering.
This avoid issues with importing VkImages through DMABUF interop from
nvdec or vaapi on drivers that doesn't support DMABUF.
Try native Vulkan hwdec first which will resolve compatibility issues if
available. If not it will fallback to using vaapi/nvdec like before.
Some languages actually require strings to be valid UTF-8, unlike C
which couldn't care less as long as it is NULL terminated.
Change triggered by Python support, but is also useful for Rust and Java.
FreeBSD supports only two latest minor versions, since 14.3 has been
released, packages for 14.1 are not longer available. Bump to 14.2,
since action doesn't have images for 14.3 yet.
Clients run in detached threads and are waited to signal when they are
finished with self mpv_destroy() call. Problem is that after detached
thread calls this function, mpv consider this client to be done and can
do whatever. One example is when mpv exits and wait for scripts to
finish we got race condition, because mpv (main thread) can exit first
and the detached thread calls ta_free() which crashes, because we may
have already destroyed things that the thread depends on.
I've seen this crash on FreeBSD CI job (libmpv-lifetime test), where the
libmpv.so has been unloaded while the thread was still doing ta_free()
```

Fix this by doing mpv_destroy() as a last step in detached threads.
CMake has been updated to 4.0 which breaks compatibility with all
project targeting version < 3.5. See for more user stories:
https://github.com/actions/runner-images/issues/11926
Remove 4.0 from path and use the one from VS installation which is
working for now. Generally we want to use only tools from VS
installation, but unfortunately Windows image provided by GHA have
polluted PATH which already causes issues in the past, that's why we
remove yet another directory from PATH.
The affected project in our case is https://github.com/webmproject/sjpeg
which is build as part of libjxl.
The buffer size were never set to 0, after first call. To retrive the
size both buffer has to be NULL and size 0. Otherwise it fails.
While at it refactor whole thing and use returned count as sanity limit.
The size of the buffer was never set so the Get*PreferredUILanguages()
were just returning ERROR_INSUFFICIENT_BUFFER.
Fix the buffer size and use the returned count as sanity limit.
Fixes the test.
After removal of `MP_MUTEX_RECURSIVE` from vdpau.c there are no more
clients of recursive mutex. Remove all the code related to it. This
commit can be reverted if in the future it is needed again. For now
let's not keep dead code.
And eliminate recursive lock. This doesn't have to be guarded by mutex,
if for some reason preemption happens while we are handling preemption,
we remember the flag and do the dance gain. This is even nicer than
locking preemption callback.
This is a bare runner for mpv.exe. There is no need for a stack
protector here and when it is forced to be added by -fno-stack-protector
it complains about missing symbols, because we don't link any standard
libs here.
Fixes:
undefined symbol: __stack_chk_fail
undefined symbol: __stack_chk_guard
We could define those, but mpv.com wrapper doesn't need it.
It can be too easy to change the video position without a single way to
undo the change. Also, this is mostly useful for images. Binding can be
brought back in a better way with an image profile or another method
that is more resistant to accidental clicks.
This reverts commit e98d3b62ec.
Fixes VO thread busy looping in paused state for untimed VOs.
One example is vo_lavc (encoding mode), used commonly to extract
thumbnail by scripts.
Example command that was affected:
mpv --ovc=rawvideo --of=image2 --ofopts=update=1 --o=test --pause
file.ext
We have to update request_redraw value to not redraw again. This has
been skipped by early exit before.
This also fixes VO_CAP_NORETAIN case.
Fixes: 8798cec7fa
The conversion is done to DXGI_FORMAT_B8G8R8X8_UNORM, this was tagged
as IMGFMT_RGB0 because vo_gpu didn't understand that B8G8R8X8 needs to be
sampled differently. This is fixed now, so we can tag the image with the
correct format.
Fixes output with dxva2 for gpu-next
(after https://github.com/haasn/libplacebo/commit/bbe63109cba2ef5c7e6aea1c47d5f6994b6dc71c)
and gpu (after previous commit).
Will fail with older libplacebo, but there is no reason to use dxva2
anyway. d3d11va is available on all supported platforms and is bit-exact
unlike dxva2 which always does conversion to 8-bit BGR.
Also note that libplacebo was broken with all BGR inputs up until
recently, and only because it was working the same as vo=gpu, the issue
was canceling out.
Those properties are already observed and trigger update, remember the
value to avoid re-fetching them.
This fixes delay caused by properties that synchronize GUI thread like
`focused` which takes 30+ ms in certain cases.

14-17 Data length in samples (binary, Little Endian)
This has been validated with sample generated with:
ffmpeg -i $(ffmpeg_fate)/lossless-audio/luckynight-partial.tak -c:a tta lucky.mka
The length is correctly calculated to be 418950 for that sample.
Basically this is a port of https://github.com/FFmpeg/FFmpeg/commit/af248fa1174200acb537a6ab1198bb2fed38e884
Fixes: d53d75e080
add_tl() when creating virtual_stream list is referencing sh->codec
which is owned by the demuxer. Don't close it to avoid dangling
pointers. The comment is right, but this happens regardless of
delay_open as we can clearly see in the add_tl() function.
It has been moved to the mpv core with additional security
considerations, including filtering unsafe protocols from being opened
via the URL handler.
While we are not aware of any active exploitation, naive protocol
handling could allow the use of niche protocols in FFmpeg, which, in
turn, might load native code. How such native code would be dropped on
the local machine is another question.
This remains theoretical, but it's better to be safe than sorry.
Fixes: 494d408583
This is useful to run mpv from URL handler. Can be used to start mpv
from you web browser or anything that would trigger url handler for
given protocol. Only safe protocols are allowed.
Current solutions to run mpv in such context are to spawn IPC proxy and
run mpv when requested, but this is in most cases not necessary.
Currently the protocol is added in mpv.desktop. Windows related
registration will follow in future changes.
