DVD-Audio discs carry an Audio Still Video Set (ASVS). An MPEG-2 still
images (cover art, booklet/lyric pages) that the disc associates with
tracks.
A new STREAM_CTRL_GET_STILL returns the still for a given playback time.
demux_disc exposes it as a selectable mpeg2video track and injects the
still as a keyframe at the track's playback time. It changes as playback
crosses track boundaries (and follows onset times when a disc encodes
them).
--dvda-page (with the new STREAM_CTRL_SET_STILL_PAGE) forces a specific
still page instead of the scheduled one. The still state is guarded by
a mutex, runtime page changes arrive from the player thread while the
demuxer thread extracts stills.
Internally the angle stays 0-based (matching the libbluray API), only
the user-visible option/property values are 1-based. BD_EVENT_ANGLE
delivers a 1-based value and is converted on arrival.
The disc VM advances when the stream is read, so in nav mode the cache
must not run ahead of what the user is seeing. Never read ahead (a
looping menu is endless). Never satisfy seeks from the cache either.
This applies to the whole disc session, not only while a menu is on
screen. The VM can jump at any time (BD-J timers, end of title), so
the cache must never run ahead of playback.
Activations still must be able to drive the VM while nothing is
consumed. demux_drive_nav() forces a single read for them.
User-facing entry point for in-disc menu navigation. The command
forwards an action (up/down/left/right/select/menu/title-menu/popup/
prev/mouse-move/mouse-click) to the current disc stream handler.
The new discnav input section allows binding controls that are only
active while a disc menu is on screen.
Setting the edition property on a disc jumps to the title through the
stream directly, so selecting the currently-playing edition can still
return to it from a menu.
Let the caller pick the OSD object instead of hardcoding EXTERNAL2, so
other bitmap overlay sources can reuse the same path. No functional
change, EXTERNAL2 is still the only user.
Add primaries, transfer, max_luma and video_colorspace arguments.
Allows tagging the colorspace of the overlay bitmap instead of assuming
sRGB. video_colorspace interprets the bitmap in the video's colorspace,
so it is tone mapped exactly like the video. max_luma overrides the
luminance peak of the bitmap. Currently only vo_gpu_next honors these
parameters. vo_gpu keeps its sRGB assumption regardless of the tag.
Fixes#10678
This allows scaling secondary subtitles independently from primary subtitles. The option defaults to 1 like --sub-scale and follows the other secondary-sub-* options by not inheriting from the primary subtitle setting.
Fixes#14989.
Back when reselect_demux_stream call was added in this path in 700f72f,
sub_redecode_cached_packets only retained the last two packets. The
subtitle decoder cache was changed in 0a4b098 to retain the whole packet
sequence. Therefore sub_redecode_cached_packets by itself can rebuild
the new decoder state entirely from packets held in memory, and we no
longer need the demuxer to refresh the track.
This fixes expensive track refresh for network streams, where changing
some sub-* options during runtime of network streams would cause the
cache to be dropped
The `ff-index` is just a index of in the track order, it doesn't carry
much meaning and may be wrong or unavailable when other than lavf
demuxer is used. Additionally some tracks may be virtual like DOVI EL
track or merged image tile grid. In which case those track are not
related to lavf at all.
No deprecation period. It was never guaranteed to match FFmpeg anyway,
so anyone who has a hard dependency on this property should reconsider.
It's not really possible to provide backward compatibility given the
ambiguity of this index. It's better to make it unavailable than making
mismatch. For user it's clear when it's not available, but not possible
to know when it's wrong.
When changing MPEG-TS program (edition) it may have completelly
different time base and duration, on live, non-seekable streams we would
just hang trying to resync to revious PTS, which is not valid. Reset the
state on edition change.
In the 2020s, now known as "the twilight years of modern
civilization", Silicon Valley's two most morbidly obese failsons
finally found their niche: a product that lets complete imbeciles
pretend to be software developers. This was, at least for a
while, a smash hit. Hordes of claudecucked vibechuds began
spamming free software projects with bogus "security bugs" and
associated even worse fixes, both of which they did not know how
to reason about, and definitely did not care to learn how to
reason about. The entire exercise, after all, was to get one's
name into the list of contributors, to get ahead in a highly
competitive job market of economies with equally torturous
education systems.
To the disturbingly moist-looking tech oligarchs recording
Goldman Sachs jerk-off instructons on their podcasts, this was a
profound shift in software development. Now, they no longer had
to pay 6 figures to some idiot who doesn't know how to program so
chooses React, and instead they can pay 6 figures to some
application that doesn't know how to program so chooses React.
For everyone else, it just added to the torment that is life in a
modern globalised service economy, where the fruits of their
labour are siphoned off and directed towards building ever
grander and more opulent paedophile island resorts.
But back to the code. Someone submitted a slop issue about how
there's UB if you run an input command with bogus parameters.
This is hardly a bug, since the commands are trusted, so the fix
is "don't do dumb shit". However, contextless vibechuddies saw
this as an opportunity to fire up their deeply subsidized
planet-burners and shit out some code they had no idea about what
it did.
LLMs, failing to have any real reasoning, tried twice, and failed
twice, to find the real """fix""" here. #18144 decided that
another condition needed to be added to the logical OR, whereas
the subsequent #18211 instead wanted to do an explicit cast to
size_t for no fucking reason. Funnily enough, the unsignedness of
size_t doesn't cause any problems here, because of the earlier
check to make sure `w` is positive.
Both of them missed that if `foo < bar * 4` overflows `bar`, you
can just check for `foo / 4 < bar`, which is an efficient
division as 4 is a power of 2, and the integer division here does
not lead to any problems because the check is a range check.
Do that, just to stop these stupid fucking PRs from popping up,
and deny these dumb shitheads the satisfaction of getting their
name into the contributor stats.
Closes#18128.
This is only used to update the list for player internal sub ext matching.
Since this handling now lives in the dnd client, it can be removed from
core, which also eliminates a global variable.
This adds dropped-file property which contains a list of dropped files
and the type of the drop. This allows clients to implement custom drag
and drop handling.
Return all subtitle lines in memory with text, start and end.
I did not name this sub-all so it cannot be misinterpreted as referring
to all subtitle tracks.
Closes#12810.
Those values are often very small, but it's still good information to
have how they are changing.
This brings those values closes to old `%+.05f%%` that were used here.
This adds proper support for MPEG-TS programs and HLS variants. Now
program selection is exposed as editions and tracks are grouped under
such edition. If there are external tracks added, they are available in
all editions.
mp_input_get_tablet_pos stores the address to an array that is protected
by lock, and the content is accessed without acquiring lock.
Fix this by writing the values to an array inside mp_input_get_tablet_pos.
Fixes: 0fbf20f057
Add optional 'default-value' and 'choices' fields where appropriate
for command arguments in the 'command-list' property. Update
documentation to reflect the command-list schema change.
DOCS/interface-changes/command-list: add changes
This uses the update_data request for clipboard backends that require it.
When clipboard monitoring is disabled, the backends will no longer
fetch data when it detects data change, and will now only do that when
receiving the update_data request.
The client now needs to run this command to update the clipboard content,
otherwise the property value is outdated.
This makes sure that applications that depend on "paste once" behavior
work correctly.
This command runs in a separate worker thread so that it can be used
as a "blocking" way to update clipboard until the update notification
arrives without blocking the playback core. It accepts a maximum timeout
parameter. This uses the existing mp_cancel mechanism to make sure this
command can be aborted and the worker threads will not stall the player
too much when quitting mpv.
For backends that do not support update_data, this command does nothing.
This version contains critical fixes to swapchain selection, correct
mapping of sRGB TRC as well as fix for gpu hangs on anv. Bump the
minimum version because the mpv experience with previous version
shouldn't be endorsed or be considered acceptable by upstream.
mmap in inherently crashy due to the file changing underneath
and requires esoteric SIGBUS handling [0] to use properly.
to reproduce, simply use "overlay-add" from a lua script with
invalid stride set and observe mpv crashing with SIGBUS.
here we're just copying the file content (introduced in
549a9ea) and munmaping it immediately so there's no real need
to be using mmap to begin with. avoid the issue entirely by just
reading the file directly with fseek+fread with optimization for
the common stride case.
one notable difference is that since dup-ed fds share same
offset, the source "fd" that's coming from client will now have
it's offset modified. `pread` could avoid this issue but it's
not supported on windows.

If you set file-local-options/foo at runtime and run playlist-play-index
current or playlist-play-index $current_pos, file-local-options/foo is
reset. Add a flag to make it preserve file-local-options.
The advantage of this change is that it allows binding Ctrl+r set
file-local-options/start ${=time-pos}; playlist-play-index current yes
to reload the current file while preserving all options, independently
of --no-config, --watch-later-options or --reset-on-next-file, and
without writing watch later files to disk. It also preserves
file-local-options set on the CLI unlike loadfile.
Scripts and things using the client API can load up playlists in a
specific order and choose what file to start playing on by using the
loadfile or loadlist commands with the play argument. However if
starting from idle mode, it is possible to send these commands before
all scripts finish initializing. mpv's core then does a prepare_playlist
call on its own for startup which will nuke the current playlist entry
set by the API user and lead to an unexpected item being played. Fix
this by not unconditionally setting pl->current to NULL allow callers to
optionally always overwrite it by getting the first item in the playlist
(e.g. if it's called after startup anywhere else in the code). Other
options like --playlist-start or --shuffle are allowed to win if they
happen to be set.
