Since we no longer have the auto choice, this is always exactly equal to
the value of the option (sub-forced-events-only). Remove the property
and alias it.
The old name is pretty bad and users mistakenly think it has something
to do with selecting forced subtitles (that would be
--subs-fallback-forced). Instead of giving it such a generic name, make
it clearer that this has to do specifically with forced sub events
which is only relevant for a small minority of subtitles.
First of all, this never worked. Or if it ever did, it was in some
select few scenarios. c9474dc9ed is what
originally added support for the auto choice. However, that commit
worked by propagating a value to a fake option used internally. This
shouldn't have ever worked because the underlying m_config_cache was
never updated so the value shouldn't have been preserved when accessed
in sd_lavc. And indeed with some testing, the value there is always 0
unsurprisingly.
This was later rewritten in ba7cc07106
along with a lot of other sub changes, but with that, it was still
mostly broken. The reason is because one of the key parts of having to
hit this logic (prefer_forced) required `--no-subs-with-matching-audio`
to be set. If the audio language matches the subtitle language (the
requirement also excludes forced subs), the option makes no subtitle
selection in the first place so pick->forced_only_def is not set to true
and nothing even happens. Another way around this would be to attempt to
change your OS language (like with the LANG environment variable) so
that the subtitle track gets selected but then audio_matches mistakenly
becomes false because it compares the OS language to the audio language
which then make preferred_forced 0, so nothing happens. I don't think
there's a scenario where pick->forced_only_def is actually set to true
(thus meaning `auto` is useless), but maybe someone could contrive
something very strange. Regardless, it's definitely not something even
remotely common.
fbe8f99194 changed track selection again
but didn't consider this particular case. The net result is that DVD/PGS
subs become equivalent to --sub-forced-only being yes, so this a change
in behavior and probably not a good one. Note that I wasn't able to
actually observe any difference in a PGS sample. It still displayed
subtitles fine but that sample probably didn't have the right flags to
hit the sub-forced-only logic.
Anyways, the auto feature is extremely questionable at best and in my
view, not actually worth it. It is meant to be used with
`--no-subs-with-matching-audio` to display forced pictures in subtitle
tracks that are not marked as forced, but that contradicts that
particular option's purpose and description in the manual (secretly
selecting a track under certain conditions even though it says not to).
Instead of trying to shove all this logic into select_default_track
which is already insanely complicated as it is, recognize that this is a
trivial lua script. If you absolutely want to turn --sub-forced-only on
under these certain conditions (DVD/PGS subtitles, matching audio and
subtitle languages, etc.), just look at the current-tracks property and
do your thing. The very, very niche behavior that this option tried to
accomplish basically never worked, no user even knows what this option
does, and well it's just not worth supporting in core mpv code. Drop
all this code for sanity's sake and change --sub-forced-only back to a
bool.
--audio-file-auto, --cover-art-auto, and --sub-auto all work by using an
internally hardcoded list that determine what file extensions get
recognized. This is fine and people periodically update it, but we can
actually expose this as a stringlist option instead. This way users can
add or remove any file extension for any type. For the most part, this
is pretty pretty easy and involves making sub_exts, etc. the defaults
for the new options (--audio-file-auto-exts, --cover-art-auto-exts, and
--sub-auto-exts). There's actually one slight complication however. The
input code uses mp_might_be_subtitle_file which guesses if the file drag
and dropped file is a subtitle. The input ctx has no access to mpctx so
we have to be clever here.
For this, the trick is to recognize that we can leverage the
m_option_change_callback. We add a new flag, UPDATE_SUB_EXTS, which
fires when the player starts up. Then in the callback, we can set the
value of sub_exts in external_files to opts->sub_auto_exts. Whenever the
option updates, the callback is fired again and sub_exts updates. That
way mp_might_be_subtitle_file can just operate off of this global
variable instead of trying to mess with the core mpv state directly.
Fixes#12000.
A bit of a long standing pain with scripting is that when opening a file
that gets interpreted as a playlist (like an m3u), the original path of
the file gets thrown away later. Workarounds basically consist of
getting the filename before mpv expands the path, but that's not really
reliable. Instead of throwing it away, save the original playlist path
by copying to the playlist entries when applicable (demuxer playlist and
the playlist option). Then expose these as properties: playlist-path for
the currently playing entry and playlist/N/playlist-path for each
specific entry. Closes#8508, #7605.
mpv makes this option an integer, but the underlying ass API actually
accepts doubles. From some testing, there is no meaningful precision
difference between float or double (it seems to go in roughly 0.05
steps), so just make it a float. sd_lavc also can handle non-integer
values here. Closes#11583.
When printing the name of the video track on the OSC, mpv almost always
prefixes it with "unknown". This is referring to the language tag which
essentially nobody ever does for the video track since it doesn't make
any sense. Instead of putting unknown when there's no language, just
make it an empty string instead. "Unknown" confuses can confuse users
here and practically nobody would guess that it's referring to language.
We still will print the language for a video track in case someone out
there really does tag it, but that should be rare.
This is pretty obscure but if you screw around with the play-dir option
to essentially create a ping-pong loop; mpv will get hit by an assertion
error. What's happening here is that changing the play-dir always
requires a seek. This is handled in player/command along with the other
runtime option changes. However, queue_seek can actually clear the value
of mpctx->stop_play if the file is ending. So while loadfile is
terminating playback and the play-dir gets changed, the value of
mpctx->stop_play gets cleared because of seek. This then hits that
assertion later when mpv tries to finish the file.
The fix is to just add some weird logic to play-dir in player/command.
We have to be sure that mpctx->play_dir matches the new direction
immediately when we get the change so explictly set it here and don't
wait for it later. Secondly, keep the old value of mpctx->stop_play
before the seek and restore it afterwards. This ensures that termination
still happens cleanly and allows the ping-pong loop to work. Fixes#10782
1df0a42a8c changed aspect-ratio from
floats to doubles, but forgot to change this function for
pretty-printing them as fractions for the video-aspect-override property
The playlist title only got set when it was specified in the playlist
file.
If there is a title after opening a file, that should also be reflected
in the playlist.
As it turns out that approach was suboptimal.
The playlist title would only ever get set when media-title actually
gets read, which depending on the configuration and usage might never
happen.
The next commit reimplements that feature in a different way.
This reverts commit 048d4d8b75 except for
the input.rst change.
This returns the value of the target OS that mpv was built on as
reported by the build system. It is quite conceivable that script
writers and API users would need to make OS-dependent choices in some
cases. Such people end up writing boilerplate/hacks to guess what OS
they are on. Assuming you trust the build system (if you don't, we're in
really deep trouble), then mpv actually knows exactly what OS it was
built on. Simply take this information at configuration time, make it a
define, and let mp_property_platform return the value.
Note that mpv has two build systems (waf and meson), so the names of the
detected OSes may not be exactly the same. Since meson is the newer
build system, the value of this property follows meson's naming
conventions*. In the waf build, there is a small function to map known
naming deviations to match meson (i.e. changing "win32" to "windows").
waf's documentation is a nightmare to follow, but it seems to simply
take the output of sys.platform in python and strip away any trailing
numbers if they exist (exception being win32 and os2)*.

This will replace shared-script-properties in new usage. It can be used for all the same things, but is much more versatile.
Clients can create arbitrary sub-objects, and text expansion can access them.
For instance, if a script sets `user-data/my-script/property1` to "test", that value will be available by expanding ${user-data/my-script/property1}.
ao-volume is represented in the code with a `struct ao_control_vol_t`
which contains volumes for two channels, left and right.
However the code implementing this property in command.c never treats
these values individually. They are always averaged together.
On the other hand the code in the AOs handling these values also has to
handle the case where *not* exactly two channels are handled.
So let's remove the `struct ao_control_vol_t` and replace it with a
simple float.
This makes the semantics clear to AO authors and allows us to drop some code from the AOs and command.c.
In debug mode the macro causes an assertion failure.
In release mode it works differently and tells the compiler that it can
assume the codepath will never execute. For this reason I was conversative
in replacing it, e.g. in mpv-internal code that exhausts all valid values
of an enum or when a condition is clear from directly preceding code.
currently only supported on x11.
one practical use-case of this is wanting to embed something (such as
dmenu) into the mpv window to use as a menu/selection. there might be
other use-cases as well (e.g doing some shenanigans with `xdotool` or
whatnot).
it's currently possible to:
* listen for 'current-window-scale' change (to check if the
window has been created or not)
* call an external tool like `xdo` or `xdotool` and grab the xid
from mpv's pid.
however it adds unnecessary dependency on external tools when mpv is
fully capable of easily providing this information.

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.
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.
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'.
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.
Nearly all the code base correctly references the data as constant. But
a couple of instances - fix those.

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.
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".
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 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".
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.
