This implements a ASS context menu to be used on platforms other than
Windows.
The select script message will allow selecting an item with a single
click when releasing a mouse button, like in native context menus. This
is mainly useful to cycle pause with one click.
It was suggested by CogentRedTester in
https://github.com/mpv-player/mpv/pull/10282#issuecomment-1858727729 and
https://github.com/mpv-player/mpv/pull/10282#issuecomment-1858809580 and
by avih that making running commands an mp.input client is a better
architecture.
A practical advantage is that completions are calculated in a different
thread, which prevents hanging when completing slow/network filesystems.
script-binding console/enable becomes script-binding commands/open,
though the console one is kept as an alias. I took the opportunity to
rename this because open makes more sense for a graphical modal, and it
is the word used in mp.input and user-data.
script-message-to console type becomes script-message-to commands type,
though the console one is kept as an alias. It is also changed to
automatically close on submit without having to append '; keypress ESC'
as you don't need to keep the console open after running prefilled
commands.
Also convert to double quotes like other scripts and rename some
inconsistent functions.
Need to shuffle some stuff around but it's pretty simple. Mute the
audio stream before the frame step and then unmute it when we're done.
It's exactly the same as the default play mode otherwise.
The refactoring in bbac628a1b missed that
the initial update handler didn't immediately run all the triggered
callbacks but would instead delay it until the next playloop. This
subtly breaks things of course like hooks, force window handling, etc.
Ensure that we immediately run all the callbacks like before on startup.

The big option callback in player/command will trigger on every single
update. This is not so great when several heavy option changes are
called in rapid succession and operations are pointlessly repeated. Try
to copy the approach that input commands do and run the actual callbacks
during the playloop. This is not really a smart or sophisticated
mechanism. It also only works for the main option cache. In theory,
other option caches like vo_opts could get spammed too and this makes no
attempt on those. But regardless, this is probably good enough for us.
mp_option_change_callback now tries to group together any new callbacks
with existing unprocessed ones and drop redundant ones whenever
something new arrives.
Previously, the default behavior of frame-step and frame-back-step is to
play forward 1 frame or seek back 1 frame. We keep this behavior but
introduce additional flags to control the exact behavior of the frame
stepping. The first argument simply specifies how many frames to go
through. The second argument specifies whether to play video to step
through frames or to seek to step through frames. Playing through the
video to step through frames only works going forwards (otherwise it
will always seek). In theory we could use backwards playback for this,
but that can be decided later.
As a minor note, MPSEEK_BACKSTEP is renamed to MPSEEK_FRAMESTEP since
forward seeks can use this as well. Fixes#10128.
When using --prefetch-playlist, if demuxer options are changed in the
time window between the start of prefetching and the playback of the
next file, the old values are used. This includes setting demuxer
options in legacy extension auto profiles.
Fix this by setting a flag when demuxer options change and not using the
prefetched data when that flag is true.
UPDATE_DEMUXER is not added to demux.c's options because those already
support updates while playing.
With --prefetch-playlist and --loop-playlist, mp_next_file() is called
continously since the last second of playback or when viewing an image,
which decreases --loop-playlist=N to 1.
Fix this by adding a flag to mp_next_file() to specify whether to
decrement --loop-playlist=N. The first playlist entry is still
prefetched when it's the next one, but without decrementing
--loop-playlist=N.
This adds a clipboard API with multiple backend and format support.
--clipboard-enable option can be toggled at runtime to turn native
clipboard on and off.
Waiting for audio_started to be set to true takes too long which causes
us to miss it for the first frame, instead invert the condition so it's
set on the first frame.
Fixes#14615
Follow up to the previous commit. Stop decreasing --ab-loop-count=N on
each iteration so it is preserved across different loops. In particular
it is preserved between different files without adding it to
--reset-on-next-file. Add a property to expose the remaning A-B loop
count instead.
The current behavior of --ab-loop-count=N is even worse than --loop-file
since it also doesn't reset when defining a new A-B loop in the same
file. Defining it has no effect after --ab-loop-count has decreased to
0, and this can't be fixed by adding it to --reset-on-next-file. This
commit also resets remaining-ab-loops every time --ab-loop-a and
--ab-loop-b are set to fix this.
This change removes convoluted core thread extraction through dispatch
added in 500ce69a06.
Currently we fully control this thread, create it and join, there is no
reason not to keep the handle of it in the player context.
As a bonus to code simplification this also fixes thread handle leak on
Windows.
Fixes: #14472
This adds script messages to select playlist entries, tracks, chapters,
subtitle lines, bindings and properties using the newly introduced
mp.input.select().
This fully closes#13964.
If the player is paused, switching subtitle track requires us to read
subs packets for an indefinite amount of time in order to actually
display the subtitles. The problem with this is that it puts a blocking
loop in the play thread which can be slow in cases where it takes a long
time to fetch the subtitle (e.g. over a network).
9e27b1f523 alleviates this when a pause
happens because of buffering, but it's not complete. One could encounter
this if the user pauses the video first manually and then switches the
subtitle track.
To solve this better, make it so the loop has a time out (totally
arbitrary number) so the player isn't blocked forever. If subtitles are
not fetched within that time, we flag the track and try again later in
the playloop.
Ended up being too flawed and caused trouble in other areas. There's
other approaches to trying to solve the issue this meant to address in
the works that should be better, so let's wait on that. Fixes#13613 and
fixes#13622.
This reverts commit e3af545421.
This seems more robust than relying on the audio status to actually be
playing. For files where there is no audio or the audio start is
delayed, this guards against that but it allows the subtraction to
always occur otherwise on normal files with audio.
Ended up being a bad idea. As a property, this inherently has more
functionality and the tradeoff of being able to do --ao-volume wasn't
worth it.
This reverts commit 58ed620c06.
Playback speed changes should be treated as a discontinuity just like
seeking. Previously, this was being treated internally as just plain
normal playback, but that can't really work. The frame timings from
before the speed change and after the speed change are completely
different and shouldn't be compared to each other. This lead to frames
being adjusted to weird places and possibly even being skipped (as if
mpv was seeking) on speed changes. What we should do is clear out and
reset all av related fields like what happens when you seek, but it is
not quite as aggressive. No need to do a full video state reset or such.
We also wait an arbitrary amount of frames before adjusting for av sync
again. compute_audio_drift already used a magic number of 10 which
sounds reasonable enough so define that and use it here. Fixes#13513.
There's too many dumb options related to subtitles which have annoying
edge cases. Try to rewrite this completely so it hopefully behaves
normally in every expected scenario. A key goal here is be smarter while
looping through the tracks and avoid selecting the subtitle if it
doesn't meet user's passed options as opposed to clearing the pick after
the fact. Fixes#13280 and fixes#13263.
This only affects two special cases: printing subtitles to the terminal
and printing subtitles on a still picture. Previously, mpv was very dumb
here and spammed this logic on every single loop. For terminal
subtitles, this isn't as big of a deal, but for the image case this is
pretty bad. The entire VO constantly redrew even when there was no need
to which can be very expensive depending on user settings.
Instead, let's rework sub_read_packets so that it also tells us whether
or not the subtitle packets update in some way in addition to telling us
whether or not to read more. Since we cache all packets thanks to the
previous commit, we can leverage this information to make a guess
whether or not the current subtitle packet is supposed to be visible on
the screen. Because the redraw now only happens when it is needed, the
mp_set_timeout_hack can be removed.
since i was going to fix the include order of stdatomic, might as well
sort the surrouding includes in accordance with the project's coding
style.
some headers can sometime require specific include order. standard
library headers usually don't. but mpv might "hack into" the standard
headers (e.g pthreads) so that complicates things a bit more.
hopefully nothing breaks. if it does, the style guide is to blame.
replace it with <stdatomic.h> and replace the mp_atomic_* typedefs with
explicit _Atomic qualified types.
also add missing config.h includes on some files.
e277fadd60 originally added this but it
never actually did anything in the function... wm4 probably changed his
mind but forget to delete it so just remove it here.
When seeking chapters, `last_chapter_seek` acts as a projection of
what the current chapter will be once mpv has a chance to seek to it.
This allows for more accurate results from the `chapter` property.
It works by comparing the projection to the actual current chapter
and returning the larger of the two indexes, but this only works when
seeking forward.
If we want it to work for both forward and backward chapter seeking,
we can instead use a boolean called `last_chapter_flag`, which gets
switched on when a chapter seek request is made, and then
switched off when the seek has been performed.
We should also check to ensure that we don't allow the chapter index
to be set to -1 unless there is a span of time between the very
beginning of the track and the start of the first chapter.
Since the new approach to resetting `last_chapter_seek` no longer
depends on `last_chapter_pts`, that member variable can be removed.
No wonder wm4 wanted to get rid of this. This option requires touching a
bunch of crap in the core player code. --stream-record works perfectly
fine and is a lot nicer so there's no need for this to exist anymore.
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.
There are a number of ways one can craft a playlist file that refers to
itself or cleverly goes around in a loop to other playlist files. There
is obviously no use for this, but mpv spins around forever trying to
load the files so you have to just SIGTERM/SIGKILL it. We can be smarter
about this and attempt to detect it. The condition for detecting this is
surprisingly simple: the filename of the first entry in the playlist
must match a previous playlist path we stored. If we get this, we can
then log an error and stop playback. If there is a "real" file loaded at
any point in time, then we know it's not an infinite loop and clear out
the saved playlist paths. Fixes#3967.
When playing a sparse video stream, the debug log gets hit with the
video EOF constantly since the audio is still playing. There's no
practical use for this so just do add some logic to only signal it once
if it is sparse.
