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.
In general, forced tracks should only be shown if they match the
language of the audio. However some people do want them no matter what,
so add an always option to this so such tracks are always selected.
This is the replacement for the previous auto option for slang. It
behaves similar however it never overrides slang if that is set and will
instead try to pick the subtitle that matches the user's language if
appropriately flagged by the file.
This proved to be too problematic. Depending on the value of
--subs-with-matching-audio, you could either end up with cases where
--slang wasn't respected and users didn't get subtitles or alternatively
cases where subtitles were given and the user didn't ask for them.
Fundamentally, the OS language functionality doesn't really map well to
slang (and for alang/vlang it makes zero sense; not that anyone actually
used it). Instead of trying to shove it in an option where it doesn't
belong, we should split this off into something else. So for now, just
remove the special handling of "auto" and flip slang back to NULL.
Ideally, users should be using lavfi-complex instead of lavfi-bridge
for such a use case, however currently lavfi-complex doesn't support
hwdec. So we can allow filters with dynamic inputs to work with
lavfi-bridge, at the cost of them only being able to take in
only one input. This should probably be reverted when/if lavfi-complex
has hwdec, but for now this allows us to use libplacebo
as a video filter with hwdec in mpv again.
--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.
1fa6669bc0 misinterpreted the example and
changed the pixel value from 128 to 168 (thinking that it meant pixels
after scaling), but likely the original calculation was correct because
the line specifically says "of the source video". This is just confusing
not really useful information so instead change the example to a more
common resolution (1920x1080) and remove any references to the source
video resolution. Also mention video-pan-y while we're at it.
It makes it more usable to virtually move dst rect instead of scaled
src.
The issue with the latter is that it is affected by video-zoom
paramters. For example if we do `--video-pan-x=-0.5` in normal case it
will move video -50%, but if we apply video-zoom/scale the video will
float towards the middle in unintuitive way. Extreme case is when one do
--video-zoom-x=0.01, now it is impossible to move video unless you
specify huge video-pan-x value, but it is limited to [-3, 3]. So you
cannot do anything.
With this changes regardless of video scale/zoom, video-pan will keep
center of scaled video in one place.
This completely disables all smoothing. Despite what the manual claims,
a decay rate of 1.0 does *not*.
It's worth pointing out that this depends on the following commit to
work properly in --vo=gpu-next, but I don't think working around such a
minor detail is worth the trouble, considering people building nightly
mpv are probably also building nightly libplacebo it should just work
(tm).

This deliberately wasn't being done when mpv was embedded
(fbccddb48b). There are some applications
that would benefit from mpv setting a title since they don't do so
themselves (such as tabbed), but at the same time some others would
probably rather not have this behavior (like smplayer). Add an option
that allows an embedded mpv to set the title if the user wishes.
Fixes#11528.
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 has a generic method for getting the display resolution, so we can
save it in vf_vapoursynth without too much trouble. Unfortunately, the
resolution won't actually be available in many cases (like my own)
because the windowing backend doesn't actually know it yet. It looks
like at least windows always returns the default monitor (maybe we
should do something similar for x11 and wayland), so there's at least
some value. Of course, this still has a bunch of pitfalls like not being
able to cope with multi monitor setups at all but so does display_fps.
As an aside, the vapoursynth API this uses apparently requires R26 (an
ancient version anyway), so bump the build to compensate for this.
Fixes#11510
The OSC reports the speed-adjusted remaining time, but the terminal does
not. This is a weird mismatch and the OSC's default behavior makes
sense, so let's just do some division and add an option to disable it.
Also named "remaining-playtime" after the OSC option. Fixes#10445.
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.
This is higher quality but comes with a slight performance hit,
especially for weaker iGPUs, so I don't want to enable it out of the box
even when --hdr-compute-peak=auto.
1669c4698d notably flipped the default of
--subs-with-matching-audio from yes to no as part of a series of changes
that gave more control over sub selection behavior. While the increased
amount of options is definitely nice, changing the default to no results
in very unintuitive behavior. For example, setting alang=en and slang=en
in your config will not show any subtitles since the audio stream is
English as well so --subs-with-matching-audio being no causes the subs
to not be be selected. This is very weird for users who reasonably
expect slang being set to actually result in showing subs and this is
what mpv did for the past decade.
The other case is when a subtitle does not have a language tag but is
flagged as default. Because --subs-fallback (a new option), defaults to
no, these subtitles also will not be loaded. This is also strange for
users since mpv previously loaded these and they would need to change
the value of this option. It's also inconsistent because audio tracks
that are tagged as default are also loaded by default.
The new behavior seems to have mostly just confused users, and it also
regresses their configs for unclear reasons. Let's just set the options
to be back in line with the old behavior with is what most users expect.
--subs-with-matching-audio goes back to being yes and the new option
--subs-fallback should be default. Fixes#11854.
Remove waf entirely in favor of meson as the only supported build
system. Waf was officially deprecated in 0.36.0, and has not been
preferred over meson since 0.35.0.
Make it clearer that you should be using --hwdec with this VO. Also make
some comments about the things that are required for this to work
correctly (i.e. working drivers/GPU and the right compositor).
To remain consistent with our belief that `auto-safe` should be the
recommended mode when turning on hw decoding, let's remap `yes` from
`auto` to `auto-safe`.
It has been odd that ctrl+h toggles `auto` for hwdecs even though we
always recommend people start with `auto-safe`, and `auto` will attempt
various hwdecs that can fail so badly we can't fall back to software
decoding.
With the change to more exhaustively attempt to use hwdecs, it is now
easier to get into situations where these fragile hwdecs will get
attempted in basic scenarios, like pressing ctrl+h.
So it is high time to default to `auto-safe`.
This adds osd support via shm buffers using a similar approach that the
normal buffers do, but it differs in a few key areas. One thing to note
is that sway and weston actually handle this extremely differently which
required all the abstractions here. In particular, weston does not cope
well with destroying the wl_buffer from shm outside of the release
handler at all (i.e. it segfaults). The workaround here is to simply
attach a NULL to the osd surface and do a surface commit before we
destroy the buffers. This is reasonable enough and seems to work well
although it's pretty weird. Sway is more straightforward although it
actually releases the osd buffer when the window goes out of sight.
Also, I found that it doesn't always release every buffer before you
close it unlike weston seems to do which is part of the reason all this
bookkeeping is required. I don't know if there's any other compositor
out there that can possibly handle vo_dmabuf_wayland right now, but
suffering through these two is good enough for now I think.
Directories were always loaded recursively, which can be slow
(e.g. one of the subdirectories is a mounting point to a slow device)
and can unexpectedly expand into a massive playlist.
Due to the problems described in 503dada42f,
this defaults to recursive loading.

--no-config should prevent loading user files of any type: configs,
cache, etc. For cache files, this case wasn't properly handled and it
was assumed they would always get something. vo_gpu's shader cache
actually already handles this, so it was left untouched. In theory,
demuxer cache should never have this issue because saving it to disk is
disabled by default (and likely that will never change), but go ahead
and change it for consistency's sake. Fixes some segfaults with
--no-config and various combinations of settings (particularly
--vo=gpu-next).
4502522a7a changed the way mpv handled and
saved cached files. In particular, it made a separate boolean option for
actually enabling cache and left the *-dir options as purely just a path
(i.e. having a dir set didn't mean you save cache). This technically
regressed people's configs, so let's just turn the cache on by default.
Linux users already expect random stuff in ~/.cache and well everyone
else can just live with some files possibly appearing in their config
directory.
Add an option for allowing pointer events to pass through the mpv
window. This could be useful in cases where a user wants to display
transparent images/video with mpv and interact with applications beneath
the window. This commit implements this functionality for x11 and
wayland. Note that whether or not this actually works likely depends on
your window manager and/or compositor. E.g. sway ignores pointer events
but the entire window becomes draggable when you float it (nothing under
the mpv window receives events). Weston behaves as expected however so
that is a compositor bug. Excuse the couple of completely unrelated
style fixes (both were originally done by me).
Notes:
- converts the (image) write() api to filenames, because using avio
with FILE* is a pain.
- adds more debug logs for screenshots.
build: rename av1 dependency to avif_muxer
wscript: unify lavf dependency with meson
Today, the only way to make mpv consider multiple hwdecs and pick the
first one that works is to use one of the `auto` modes. But the list
that is considered in those cases is hard-coded. If the user wants to
provide their own list, they are out of luck.
And I think that there is now a significant reason to support this -
the new Vulkan hwdec is definitely not ready to be in the auto list,
but if you want to use it by default, it will not work with many codecs
that are normally hardware decodable (only h.264, hevc and av1 if you
are very lucky). Everything else will fall back to software decoding.
Instead, what you really want to say is: use Vulkan for whatever it
supports, and fall back to my old hwdec for everything else.
One side-effect of this implementation is that you can freely mix
hwdec names and special values like `auto` and `no`. The behaviour will
be correct, so I didn't try and prohibit any combinations. However,
some combinations will be silly - eg: sticking any further values after
`no` will result in them being ignored. On the other hand, a
combination like `vulkan,auto` could be very useful as that will use
Vulkan if possible, and if not, run the normal auto routine.
Fixes#11797
Some platforms (wayland) apparently have a lot of trouble with drag and
drop. The default behavior is still the same which is basically obeying
what we get from the window manager/compositor, but the --drag-and-drop
option allows forcibly overriding the drag and drop behavior. i.e. you
can force it to always replace the playlist or append at the end. This
only implements this in X11 and Wayland but in theory windows and macos
could find this option useful (both hardcode the shift key for
appending). Patches welcome.
It is worth adding this example because it has been asked multiple times
in the issue tracker and the IRC channel.
string.find() is used because it's 20 times faster than string.match().
Vulkan Video Decoding has finally become a reality, as it's now
showing up in shipping drivers, and the ffmpeg support has been
merged.
With that in mind, this change introduces HW interop support for
ffmpeg Vulkan frames. The implementation is functionally complete - it
can display frames produced by hardware decoding, and it can work with
ffmpeg vulkan filters. There are still various caveats due to gaps and
bugs in drivers, so YMMV, as always.
Primary testing has been done on Intel, AMD, and nvidia hardware on
Linux with basic Windows testing on nvidia.
Notable caveats:
* Due to driver bugs, video decoding on nvidia does not work right now,
unless you use the Vulkan Beta driver. It can be worked around, but
requires ffmpeg changes that are not considered acceptable to merge.
* Even if those work-arounds are applied, Vulkan filters will not work
on video that was decoded by Vulkan, due to additional bugs in the
nvidia drivers. The filters do work correctly on content decoded some
other way, and then uploaded to Vulkan (eg: Decode with nvdec, upload
with --vf=format=vulkan)
* Vulkan filters can only be used with drivers that support
VK_EXT_descriptor_buffer which doesn't include Intel ANV as yet.
There is an MR outstanding for this.
* When dealing with 1080p content, there may be some visual distortion
in the bottom lines of frames due to chroma scaling incorporating the
extra hidden lines at the bottom of the frame (1080p content is
actually stored as 1088 lines), depending on the hardware/driver
combination and the scaling algorithm. This cannot be easily
addressed as the mechanical fix for it violates the Vulkan spec, and
probably requires a spec change to resolve properly.
All of these caveats will be fixed in either drivers or ffmpeg, and so
will not require mpv changes (unless something unexpected happens)
If you want to run on nvidia with the non-beta drivers, you can this
ffmpeg tree with the work-around patches:

This adds cache as a possible path for mpv to internally pick
(~/.cache/mpv for non-darwin unix-like systems, the usual config
directory for everyone else). For gpu shader cache and icc cache,
controlling whether or not to write such files is done with the new
--gpu-shader-cache and --icc-cache options respectively. Additionally,
--cache-on-disk no longer requires explicitly setting the --cache-dir
option. The old options, --cache-dir, --gpu-shader-cache-dir, and
--icc-cache-dir simply set an override for the directory to save cache
files. If unset, then the cache is saved in XDG_CACHE_HOME.
A pain point for some users is the fact that watch_later is stored in
the ~/.config directory when it's really not configuration data. Roughly
2 years ago, XDG_STATE_DIR was added to the XDG Base Directory
Specification[0] and its description, user-specific state data, actually
perfectly matches what watch_later data is for. Let's go ahead and use
this directory as the default for watch_later. This change only affects
non-darwin unix-like systems (i.e. Linux, BSDs, etc.). The directory
doesn't move for anyone else.
Internally, quite a few things change with regards to the path
selection. If the platform in question does not have a statedir concept,
then the path selection will simply return "home" instead (old
behavior). Fixes#9147.

This finally allows us to put any user defined options into the
CONFIGURATION variable like what waf does. The arbitrary hardcoded
fallback is left in place for old meson versions. Also update the
documentation in regards to the mpv-configuration variable to be
relevant to meson.
Instead of erroring when values returned by profile-cond expressions
aren't booleans, apply the relative profiles as long as the return
values are truthy. This allows shortening conditions like
profile-cond=path:match('foo') ~= nil
to
profile-cond=path:match('foo')
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.
This reworks all of mpv's unit tests so they are compiled as separate
executables (optional) and run via meson test. Because most of the tests
are dependant on mpv's internals, existing compiled objects are
leveraged to create static libs and used when necessary. As an aside, a
function was moved into video/out/gpu/utils for sanity's sake (otherwise
most of vo would have been needed). As a plus, meson multithreads
running tests automatically and also the output no longer pollutes the
source directory. There are tests that can break due to ffmpeg changes,
so they require a specific minimum libavutil version to be built.
Since meson has its own unit testing system, let's rework mpv's tests so
they integrate nicely with this. To prepare for this, start off by
dropping the unittest option. Of course, this means that tests will no
longer be supported in the waf build at all but it will be dropped
anyway. Note that the tests option is preserved for the meson build. We
will still make use of this in the future commits.
mpv's window resizing logic always automatically resized the window
whenever the video resolution changed (i.e. advancing forward in a
playlist). This simply introduces the option to make this behavior
configurable. Every windowing backend would need to implement this
behavior in their code since a reconfigure event must always be a
resize. The params of the frame changed so you either have to resize the
window to the new size of the params or make the params the same size as
the window. This commit implements it for wayland, win32, and x11.
These options make it possible to specify the directory that will be
passed to ass_set_fonts_dir(), akin to VLC's `--ssa-fontsdir` and
FFmpeg's `fontsdir`.
Fixes#8338
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)*.

PipeWire supports a global volume control for streams that works on top
of the per-channel volumes.
As mpv only supports a single volume with ao-volume it can make sense to
use the single global volume from PipeWire for it.
This allows the user to also specify per-channel volumes and not have
mpv trample over them.
This mode is not the default as pulseaudio does not support this
global volume control and all tooling controlling PipeWire via
pipewire-pulse (like pavucontrol) will not be able to see this channel.
This option is a bit obscure, but some people do use it and it can be
useful. The actual code that implements this is very simple, so there's
really no need to have a scary note in the docs about it possibly
changing or being removed.
3a9e661e92 officially made this video
filter deprecated roughly 6 years ago. Every other video filter in that
commit has actually been removed since then except for vf_sub. ffmpeg
does have its own subtitles filter, but it doesn't have the same control
over scale like vf_sub does. That's probably why wm4 never actually
removed it. Let's stop scaring users with a warning since this filter
probably won't ever get removed. Closes#9254.
