With the recent vo_opengl changes it doesn't do anything anymore.
I don't think a deprecation period is necessary, because the command
was always marked as experimental.

vo_opengl sub-option were always rather annoying to handle. It seems
better to make them global options instead. This is simpler and easier
to use. The only disadvantage we are aware of is that it's not clear
that many/all of these new global options work with vo_opengl only.
--vo=opengl-hq is also deprecated.
There is extensive compatibility with the old behavior. One exception is
that --vo-defaults will not apply to opengl-hq (though with opengl it
still works). vo-cmdline is also dysfunctional and will be removed in a
following commit.
These changes also affect opengl-cb.
The update mechanism is still rather inefficient: it requires syncing
with the VO after each option change, rather than batching updates.
There's also no granularity (video.c just updates "everything", and if
auto-ICC profiles are enabled, vo_opengl.c will fetch them on each
update).
Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.

The way option runtime changes are handled is pretty bad in the current
codebase. There's a big option struct (MPOpts), which contains almost
everything, and for which no synchronization mechanism exists. This was
handled by either making some options read-only after initialization,
duplicating the option struct, using sub-options (in the VO), and so on.
Introduce a mechanism that creates a copy of the global options (or
parts of it), and provides a well-defined way to update them in a
thread-safe way.
Most code can remain the same, just that all the component glue code has
to explicitly make use of it first.
There is still lots of room for improvement. For example, the update
mechanism could be better.

If the win32 taskbar progress update is sent before the VO window is
created, then w32_common.c will ignore it because the actual taskbar
object was not created yet. (At least this is what I suspect happens.
The window is already created at this point, but not mapped.)
Hopefully fix this is fixed by creating until after the window is
created, i.e. the VO has been configured at least once.
Untested (who wants to boot into Windows just to wait until it has
applied all of its stupid updates).
Also not explicit is whether update_vo_playback_state() will actually be
called soon enough in all cases. It probably is.
Probably fixes #3482.

Create the core thread right in mpv_create(), and reduce what
mpv_initialize() does further. This is simpler, and allows the API user
to do more before calling mpv_initialize(). The latter is not the real
goal, rather we'd like mpv_intialize() reduced to do almost nothing. It
still does a lot, but nothing truly special anymore that is absolutely
required for basic mpv workings.
One thing we want the user to be able to do is changing properties
before mpv_initialize() to reduce the special status of
mpv_set_option().

Make some existing properties behave more like options. This mostly
means they don't deny access if the associated component is not active,
but redirects to the option.
One kind of fishy change is that we apply --brightness etc. only if
they're not set to the default value. This won't necessarily work with
--vo=xv, but affects only cases where 1. the Xv adapter has been changed
to non-defaults, and 2. the user tries to reset them with mpv by passing
e.g. --brightness=0. We don't care about Xv, and the noted use-case is
dumb, so this change is acceptable.

They were delcared to be removed in mpv 0.20.0, and the next release
will be 0.21.0.

These conflict with options of the same name, and prevent a "full"
unification. Not addressed is the "cache" property, and possibly a few
properties that behave differently from their equivalent options.

Now options are accessible through the property list as well, which
unifies them to a degree.
Not all options support runtime changes (meaning affected components
need to be restarted for the options to take effects). Remove from the
manpage those properties which are cleanly mapped to options anyway.
From the user-perspective they're just options available through the
property interface.

Before this commit, all VOs had to toggle the option flag themselves,
now command.c does it.
I can't really comprehend why it required every VO to do this manually.
Maybe it was for rejecting the property/option change if the VO didn't
support a specific capability. But then it could have checked the VOCTRL
result. In any case, I don't care, and successfully changing the
property without doing anything (With some VOs) is fine too. Many things
work this way now, and it's simpler overall.
This change will be useful for cleaning up VO option handling.

Just a minor refactor along the planned option change. This commit will
make it easier to update (i.e. copy) the VO options without copying
_all_ options. For now, behavior should be equivalent, though.
(The VO options were put into a separate struct quite early - when all
global variables were removed from the source code. It wasn't clear
whether the separate struct would have any actual purpose, but it seems
it will now. Awesome, huh.)

Some files not only use rounded timestamps, but they also do it
incorrectly. They may jitter between up to 4 specific frame durations.
In this case, I found a file that mostly used 41ms and 42ms, but also
had 40ms and 43ms outliers (often but not always following each other).
This breaks the assumption of the framerate estimation code that the
frame duration can deviate up to 1ms. If it jitters around 4 possible
frame durations, the maximum deviation is 3ms. Increase it accordingly.
The change might make playback of "true VFR" video via display-sync mode
worse, but it's not like it was particularly good in the first place.
Also, the check whether to usen the container FPS needs to be stricter.
In the worst case, num_dur is 1, which doesn't really indicate any
evidence that the framerate is correct. Only if there are "enough"
frames the deviation check will become meaningful. 16 is an arbitrary
value that has been designated "enough" by myself.
Also otuput the frame duration values for --dump-stats.

Normally, OSD can be disabled with --osd-level=0. But this also disables
terminal OSD, and some users want _only_ the terminal OSD. Add
--video-osd=no, which essentially disables the video OSD.
Ideally, it should probably be possible to control terminal and video
OSD levels independently, but that would require separate OSD timers
(and other state) for both components, so don't do it. But because the
current situation isn't too ideal, add a threat to the manpage that
might be changed in the future.
Fixes #3387.

Cleaner and makes it easier to change the underlying stream.
mp_property_stream_capture() still directly accesses it directly via
demux_run_on_thread(). This is evil, but still somewhat sane and is not
getting into the way here.

Doing this required synchronizing with the VO thread, which could lead
to audio dropouts if the VO was frozen (which can happen in practice if
e.g. an opengl_cb user is not doing what the API demands).
Add a way to send asynchronous VOCTRLs, and use that for the playback
state. In theory, it would be better to make this status update a
several function and to "merge" several queued update, but that would be
slightly more effort/code, and the update is so infrequent that the
merging would never happen anyway.
The change to vo_destroy() is to make sure all queued asynchronous
reuqests are finished before making the vo_thread exit.
Even though it's only used on MS Windows, it's run on any platform with
any VO, which makes this worse.

When fetching the playlist property, playlist_entry_from_index would be
called for each playlist entry, which traversed a linked list to get the
entry corresponding to the specified index. This was very slow for large
playlists. Since get_playlist_entry is called for each index in order,
it can avoid a full traversal of the linked list by using the next
pointer on the previously requested entry.

This affects A-B loops and --loop-file, and audio. Instead of dropping
audio by resetting the AO, try to make it seamless by not sending data
after the loop point, and after the seek send new data without a reset.

The code actually kept going out of EOF mode into resync mode back into
EOF mode when the playloop had to wait after an audio EOF caused by the
endpts. This would break seamless looping (as added by the next commit).
Apply endpts earlier, to ensure the filter_audio() function always
returns AD_EOF in this case.
The idiotic ao_buffer makes this an amazing pain in the ass.

Instead of letting it keep decoding by trying to find a new frame,
"plug" the frame queue by not removing it. (Or actually, by putting
it back instead of discarding it.)
Matters for seamless looping (following commits), and possibly some
other corner cases.
The added function vf_unread_output_frame() is a bit of a sin, but still
reasonable, since its implementation is trivial.

The --image-display-duration option controls how long an image is
displayed. It's also possible to display the image forever (until manual
user interaction stops playback).
With this, the core drops the old method to "drain" video (i.e. waiting
for the last frame duration on end of playback). Instead, we reuse
MPContext.time_frame. The old mechanism was disabled for non-images
anyway.
Fixes #3425.

Change the last parameter from a bool to an int, which is supposed to
take bit-flags. The at this point only flag is MPSEEK_FLAG_DELAY, which
replaces the previous bool parameter. The old false parameter becomes 0,
the old true parameter becomes MPSEEK_FLAG_DELAY.
Since the old "immediate" parameter is now essentially inverted, two
coalesced immediate and delayed seeks end up as delayed instead of
immediate. This change doesn't matter, since there are no relative
immediate seeks anyway.

Relative seeks backwards with external audio tracks does not always work
well: it tends to happen that video seek back further than audio, so
audio will remain silent until the audio's after-seek position is
reached. This happens because we strictly seek both video and audio
demuxer to the approximate desirted target PTS, and then start decoding
from that.
Commit 81358380 removes an older method that was supposed to deal with
this. It was sort of bad, because it could lead to the playback core
freezing by waiting on network.
Ideally, the demuxer layer would probably somehow deal with such seeks,
and do them in a way the audio is seeked after video. Currently this is
infeasible, because the demuxer layer assumes a single demuxer, and
external tracks simply use separate demuxer layers. (MPlayer actually
had a pseudo-demuxer that joined external tracks into a single demuxer,
but this is not flexible enough - and also, the demuxer layer as it
currently exists can't deal with dynamically removing external tracks
either. Maybe some time in the future.)
Instead, add a gross hack, that essentially reseeks the audio if it
detects that it's too far off. The result is actually not too bad,
because we can reuse the mechanism that is used for instant track
switching. This way we can make sure of the right position, without
having to care about certain other issues.
It should be noted that if the audio demuxer is used for other tracks
too, and the demuxer does not support refresh seeking, audio will
probably be off by even a higher amount. But this should be rare.

This code is for resyncing audio-only streams (e.g. switching between
audio tracks if no video track is active). This must not be run if the
video PTS just isn't known yet. (Although the case in which this changes
anything is probably very obscure, if it can even happen. Still, it's a
bit more correct.)
This is a correction to commit 91a3bda6.

In display-sync mode, the very first video frame is idiotically fully
timed, even though audio has not been synced yet at this point, and the
video frame is more like a "preview" frame. But since it's fully timed,
an underflow is detected if audio takes longer than the display time of
the frame (we send the second frame only after audio is done).
The timing code will try to compensate for the determined desync, but it
really shouldn't. So explicitly discard the timing info in this specific
case. On the other hand, if the first frame still hasn't finished
display, we can pretend everything is ok.
This is a hack - ideally, we either would send a frame without timing
info (and then send it again or so when playback starts properly), or we
would add real pause support to the VO, and pause it during syncing.

If an audio track is enabled during playback, then make it resume at the
exact "current position", instead of playing audio before that position.
This was already done for video.

When switching tracks, we normally have the problem that data gets lost
due to readahead buffering. (Which in turn is because we're stubborn and
instruct the demuxers to discard data on unselected streams.) The
demuxer layer has a hack that re-reads discarded buffered data if a
stream is enabled mid-stream, so track switching will seem instant.
A somewhat similar problem is when all tracks of an external files were
disabled - when enabling the first track, we have to seek to the target
position.
Handle these with the same mechanism. Pass the "current time" to the
demuxer's stream switch function, and let the demuxer figure out what to
do. The demuxer will issue a refresh seek (if possible) to update the
new stream, or will issue a "normal" seek if there was no active stream
yet.
One case that changes is when a video/audio stream is enabled on an
external file with only a subtitle stream active, and the demuxer does
not support rrefresh seeks. This is a fuzzy case, because subtitles are
sparse, and the demuxer might have skipped large amounts of data. We
used to seek (and send the subtitle decoder some subtitle packets
twice). This case is sort of obscure and insane, and the fix would be
questionable, so we simply don't care.
Should mostly fix #3392.

This commit adds an --audio-channel=auto-safe mode, and makes it the
default. This mode behaves like "auto" with most AOs, except with
ao_alsa. The intention is to allow multichannel output by default on
sane APIs. ALSA is not sane as in it's so low level that it will e.g.
configure any layout over HDMI, even if the connected A/V receiver does
not support it. The HDMI fuckup is of course not ALSA's fault, but other
audio APIs normally isolate applications from dealing with this and
require the user to globally configure the correct output layout.
This will help with other AOs too. ao_lavc (encoding) is changed to the
new semantics as well, because it used to force stereo (perhaps because
encoding mode is supposed to produce safe files for crap devices?).
Exclusive mode output on Windows might need to be adjusted accordingly,
as it grants the same kind of low level access as ALSA (requires more
research).
In addition to the things mentioned above, the --audio-channels option
is extended to accept a set of channel layouts. This is supposed to be
the correct way to configure mpv ALSA multichannel output. You need to
put a list of channel layouts that your A/V receiver supports.

Pointless anyway. With superficial checking I couldn't find any decoder
which actually outputs this, and AO chmap negotiation would properly
ignore them anyway in most cases.

Assume you use a large value like --audio-delay=20. Then until now the
player would just have seeked normally to a "too late" position, and
played silence for about 20 seconds until audio in the correct time
range is coming again.
Change this by offsetting seeks by the right amount. This works for both
external and muxed files. If a seek isn't precise, then it works only
for external files.
This might cause issues with very large delay options. Hr-seek skipping
could take a lot of time (especially because it affects video too), the
demuxer queue could overflow, and other weird corner cases could appear.
But we just try this on best-effort basis, and if the user uses extreme
values we don't guarantee good behavior.

Otherwise it behaves dumb. (Although you could argue it shouldn't try to

mixer.c didn't really deserve to be separate anymore, as half of its
contents were unnecessary glue code after recent changes. It also
created a weird split between audio.c and af.c due to the fact that
mixer.c could insert audio filters. With the code being in audio.c
directly, together with other code that unserts filters during runtime,
it will be possible to cleanup this code a bit and make it work like the
