There is some sort-of awkwardness here, because option access needs to
happen in a synchronized manner, and the framedrop flag is not in the VO
option struct. Remove the mp_read_option_raw() call and the awkward
change notification via VO_EVENT_WIN_STATE from command.c, and pass it
through as new vo_frame flag.
The playback start logic explicitly waits until the first frame has been
displayed. Usually this will introduce a wait of 1 vsync. For normal
playback this doesn't matter, but with respect to low latency needs,
this only leads to additional data getting queued up in the demuxer or
network buffers.
Another thing is that the timing logic decodes 1 frame ahead (= 1 frame
extra latency) to determine the exact duration of a frame.
To be fair, there doesn't really seem to be a hard reason why this is
needed. With the current code, enabling the option does lead to A/V
desync sometimes (if the demuxer FPS is too inaccurate), and also frame
drops at playback start in some situations. But this all seems to be
avoidable, if the timing logic were to be rewritten completely, which
should probably happen in the future. Thus the new option comes with the
warning that it can be removed any time. This is also why the option has
"hack" in the name.
The purpose of the new API is to make it useable with other APIs than
OpenGL, especially D3D11 and vulkan. In theory it's now possible to
support other vo_gpu backends, as well as backends that don't use the
vo_gpu code at all.
This also aims to get rid of the dumb mpv_get_sub_api() function. The
life cycle of the new mpv_render_context is a bit different from
mpv_opengl_cb_context, and you explicitly create/destroy the new
context, instead of calling init/uninit on an object returned by
mpv_get_sub_api().
In other to make the render API generic, it's annoyingly EGL style, and
requires you to pass in API-specific objects to generic functions. This
is to avoid explicit objects like the internal ra API has, because that
sounds more complicated and annoying for an API that's supposed to never
change.
The opengl_cb API will continue to exist for a bit longer, but
internally there are already a few tradeoffs, like reduced
thread-safety.
Mostly untested. Seems to work fine with mpc-qt.
This fixes playback stalls on some mediacodec hardware decoders,
which expect that frame buffers will be rendered and returned back
to the decoder as soon as possible.
Specifically, the issue was observed on an NVidia SHIELD Android TV,
only when playing an H264 sample which switched between interlaced
and non-interlaced frames. On an interlacing change, the decoder
expects all outstanding frames would be returned to it before it
would emit any new frames. Since a single extra frame always remained
buffered by mpv, playback would stall. After this commit, no extra
frames are buffered by mpv when using vo_mediacodec_embed.
Use the decoder wrapper that was introduced for video. This removes all
code duplication the old audio decoder wrapper had with the video code.
(The audio wrapper was copy pasted from the video one over a decade ago,
and has been kept in sync ever since by the power of copy&paste. Since
the original copy&paste was possibly done by someone who did not answer
to the LGPL relicensing, this should also remove all doubts about
whether any of this code is left, since we now completely remove any
code that could possibly have been based on it.)
There is some complication with spdif handling, and a minor behavior
change (it will restrict the list of codecs to spdif if spdif is to be
used), but there should not be any difference in practice.
Move dec_video.c to filters/f_decoder_wrapper.c. It essentially becomes
a source filter. vd.h mostly disappears, because mp_filter takes care of
the dataflow, but its remains are in struct mp_decoder_fns.
One goal is to simplify dataflow by letting the filter framework handle
it (or more accurately, using its conventions). One result is that the
decode calls disappear from video.c, because we simply connect the
decoder wrapper and the filter chain with mp_pin_connect().
Another goal is to eventually remove the code duplication between the
audio and video paths for this. This commit prepares for this by trying
to make f_decoder_wrapper.c extensible, so it can be used for audio as
well later.
Decoder framedropping changes a bit. It doesn't seem to be worse than
before, and it's an obscure feature, so I'm content with its new state.
Some special code that was apparently meant to avoid dropping too many
frames in a row is removed, though.
I'm not sure how the source code tree should be organized. For one,
video/decode/vd_lavc.c is the only file in its directory, which is a bit
annoying.
Get rid of the old vf.c code. Replace it with a generic filtering
framework, which can potentially handle more than just --vf. At least
reimplementing --af with this code is planned.
This changes some --vf semantics (including runtime behavior and the
"vf" command). The most important ones are listed in interface-changes.
vf_convert.c is renamed to f_swscale.c. It is now an internal filter
that can not be inserted by the user manually.
f_lavfi.c is a refactor of player/lavfi.c. The latter will be removed
once --lavfi-complex is reimplemented on top of f_lavfi.c. (which is
conceptually easy, but a big mess due to the data flow changes).
The existing filters are all changed heavily. The data flow of the new
filter framework is different. Especially EOF handling changes - EOF is
now a "frame" rather than a state, and must be passed through exactly
once.
Another major thing is that all filters must support dynamic format
changes. The filter reconfig() function goes away. (This sounds complex,
but since all filters need to handle EOF draining anyway, they can use
the same code, and it removes the mess with reconfig() having to predict
the output format, which completely breaks with libavfilter anyway.)
In addition, there is no automatic format negotiation or conversion.
libavfilter's primitive and insufficient API simply doesn't allow us to
do this in a reasonable way. Instead, filters can use f_autoconvert as
sub-filter, and tell it which formats they support. This filter will in
turn add actual conversion filters, such as f_swscale, to perform
necessary format changes.
vf_vapoursynth.c uses the same basic principle of operation as before,
but with worryingly different details in data flow. Still appears to
work.
The hardware deint filters (vf_vavpp.c, vf_d3d11vpp.c, vf_vdpaupp.c) are
heavily changed. Fortunately, they all used refqueue.c, which is for
sharing the data flow logic (especially for managing future/past
surfaces and such). It turns out it can be used to factor out most of
the data flow. Some of these filters accepted software input. Instead of
having ad-hoc upload code in each filter, surface upload is now
delegated to f_autoconvert, which can use f_hwupload to perform this.
Exporting VO capabilities is still a big mess (mp_stream_info stuff).
The D3D11 code drops the redundant image formats, and all code uses the
hw_subfmt (sw_format in FFmpeg) instead. Although that too seems to be a
big mess for now.
f_async_queue is unused.
I've decided that MP_TRACE means “noisy spam per frame”, whereas
MP_DBG just means “more verbose debugging messages than MSGL_V”.
Basically, MSGL_DBG shouldn't create spam per frame like it currently
does, and MSGL_V should make sense to the end-user and provide mostly
additional informational output.
MP_DBG is basically what I want to make the new default for --log-file,
so the cut-off point for MP_DBG is if we probably want to know if for
debugging purposes but the user most likely doesn't care about on the
terminal.
Also, the debug callbacks for libass and ffmpeg got bumped in their
verbosity levels slightly, because being external components they're a
bit less relevant to mpv debugging, and a bit too over-eager in what
they consider to be relevant information.
I exclusively used the "try it on my machine and remove messages from
MSGL_* until it does what I want it to" approach of refactoring, so
YMMV.
update_subtitles() makes sure all subtitle packets at/before the given
PTS have been read and processed. Normally, this function is only called
before sending a frame to the VO. This is too late for vf_sub, which
expects the subtitles to be updated before feeding a frame to the
filters.
Apparently this was specifically a problem for the first frame.
Subsequent frames might have been ok due to general prefetching.
(This will fail anyway, should a filter dare to add an offset to the
timestamps of the filered frames before they pass to vf_sub.)
Fixes#5194.
The internal stereo3d filter was removed due to being GPL only, and due
to being a mess that somehow used libavfilter's filter. Without this
filter, it's hard to remove our internal stereo3d image attribute, so
even using libavfilter's stereo3d filter would not work too well (unless
someone fixes it and makes it able to use AVFrame metadata, which we
then could mirror in mp_image).
This was never well thought-through anyway, so just drop it. I think
some "downsampling" support would still make sense, maybe that can be
readded later.
Now using libavfilter filters directly.
The rotation case is a bit lazy, because it uses the slow vf_rotate
filter in all cases, instead of using special filters for 90° step
rotations.
This code could not be relicensed. The intention was to write new filter
code (which could handle both audio and video), but that's a bit of
work. Write some code that can do audio conversion (resampling,
downmixing, etc.) without the old audio filter chain code in order to
speed up the LGPL relicensing.
If you build with --disable-libaf, nothing in audio/filter/* is compiled
in. It breaks a few features, such as --volume, --af, pitch correction
on speed changes, replaygain.
Most likely this adds some bugs, even if --disable-libaf is not used.
(How the fuck does EOF notification work again anyway?)
This removes all GPL only code from it, and that's the whole purpose.
Also happens to be much simpler.
The "deinterlace" option still sort of exists, but only as runtime
changeable option. The main change in behavior is that the property will
not report back the actual deint state. Or in other words, if inserting
or initializing the filter fails, the deinterlace property will still
return "yes". This is in line with most recent behavior changes to
properties and options.
I really wouldn't care much about this, but some parts of the core code
are under HAVE_GPL, so there's some need to get rid of it. Simply turn
the video equalizer from its current fine-grained handling with vf/vo
fallbacks into global options. This makes updating them much simpler.
This removes any possibility of applying video equalizers in filters,
which affects vf_scale, and the previously removed vf_eq. Not a big
loss, since the preferred VOs have this builtin.
Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and
vo_xv. I'm not going to waste my time on these legacy VOs.
vo.eq_opts_cache exists _only_ to send a VOCTRL_SET_EQUALIZER, which
exists _only_ to trigger a redraw. This seems silly, but for now I feel
like this is less of a pain. The rest of the equalizer using code is
self-updating.
See commit 96b906a51d for how some video equalizer code was GPL only.
Some command line option names and ranges can probably be traced back to
a GPL only committer, but we don't consider these copyrightable.
This is pretty pointless, but I believe it allows us to claim that the
new code is not affected by the copyright of the old code. This is
needed, because the original mp_audio struct was written by someone who
has disagreed with LGPL relicensing (it was called af_data at the time,
and was defined in af.h).
The "GPL'ed" struct contents that surive are pretty trivial: just the
data pointer, and some metadata like the format, samplerate, etc. - but
at least in this case, any new code would be extremely similar anyway,
and I'm not really sure whether it's OK to claim different copyright. So
what we do is we just use AVFrame (which of course is LGPL with 100%
certainty), and add some accessors around it to adapt it to mpv
conventions.
Also, this gets rid of some annoying conventions of mp_audio, like the
struct fields that require using an accessor to write to them anyway.
For the most part, this change is only dumb replacements of mp_audio
related functions and fields. One minor actual change is that you can't
allocate the new type on the stack anymore.
Some code still uses mp_audio. All audio filter code will be deleted, so
it makes no sense to convert this code. (Audio filters which are LGPL
and which we keep will have to be ported to a new filter infrastructure
anyway.) player/audio.c uses it because it interacts with the old filter
code. push.c has some complex use of mp_audio and mp_audio_buffer, but
this and pull.c will most likely be rewritten to do something else.
Refresh seeks are automatically issued when changing filters, which
improves user experience if these filters change buffering or such.
The refresh seek could actually overwrite a previously ongoing seek:
set pause yes
set time-pos 10
set vf ""
Here, the video code issued a refresh seek to the previous video
position, which could be different from the previously triggered (and
still ongoing) seek, this overwriting the seek.
Factor all refresh seek handling into a new function, and make it handle
ongoing seeks correctly.
Remove the weird new canonical_pts field, which actually had no use.
Fixes#4757.
Commit f1d161d55f accidentally added the handle_force_window() call if
no track is selected.
This was OK, but breaks something like "mpv *", where some files are not
playable (like subtitle files) - the unplayable files would remove and
recreate the VO window, which is annoying.
Just drop the call again.
Tends to be somewhat glitchy if subtitles are enabled, and you enable
and disable tracks.
On error, this will disable --lavfi-complex, which will result in
whatever behavior.
Commit 0e0b87b6f3 fixed that dropped packets did not trigger further
work correctly. But it also made trivial --lavfi-complex freeze. The
reason is that the meaning if DATA_AGAIN was overloaded: the decoders
meant that they should be called again, while lavfi.c meant that other
outputs needed to be checked again. Rename the latter meaning to
DATA_STARVE, which means that the current input will deliver no more
data, until "other" work has been done (like reading other outputs, or
feeding input).
The decoders never return DATA_STARVE, because they don't get input from
the player core (instead, they get it from the demuxer directly, which
is why they still can return DATA_WAIT).
Also document the DATA_* semantics in the enum.
Fixes#4746.
Can be enabled via --vd-lavc-dr=yes. See manpage additions for what it
does.
This reminds of the MPlayer -dr flag, but the implementation is
completely different. It's the same basic concept: letting the decoder
render into a GPU buffer to avoid a copy. Unlike MPlayer, this doesn't
try to go through filters (libavfilter doesn't support this anyway).
Unless a filter can work in-place, DR will be silently disabled. MPlayer
had very complex semantics about buffer types and management (which
apparently nobody ever understood) and weird restrictions that mostly
limited it to mpeg2 style codecs. The mpv code does not do any of this,
and just lets the decoder allocate an arbitrary number of untyped
images. (No MPlayer code was used.)
Parts of the code based on work by atomnuker (starting point for the
generic code) and haasn (some GL definitions, some basic PBO code, and
correct fencing).
These files have all in common that they were fully or mostly taken from
mplayer.c. (mplayer.c was a huge file that contains almost all of the
playback core, until it was split into multiple parts.) This was
probably the hardest part to relicense, because so much code was moved
around all the time.
player/audio.c still does not compile. We'll have to redo audio
filtering. Once that is done, we can probably actually provide an
actual LGPL configure switch.
Here is a relatively detailed list of potential issues:
8d190244: author did not reply, parts were made GPL-only in a previous
commit.
7882ea9b: author could not be reached, but the code is gone. wscript
still has --datadir switch, but I don't think this is relevant to
copyright.
f197efd5: unclear origin, but I consider the code gone anyway (replaced
with generic OSD mechanisms).
8337d9c2: author did not reply, but only the option still exists (under
a different name), other code was removed.
d8fd7131: did not reply. Disabled in a previous commit.
05258251: same author as above. Both fields actually seem to have
vanished (even when tracking renames), so no action taken.
d459e644, 268b2c1a: author did not reply, but we reuse only the options
(with different names and slightly or fully different semantics, and
completely different implementations), so I don't think this is relevant
for copyright.
09e742fe, 17c39c4e: same as above.
e8a173de, bff4b3ee: author could not be reached. The commands were
reworked to properties, and the code outside of the TV code were moved
back to the TV code. So I don't think copyright applies to the current
command.c parts (mp_property_tv_color, mp_property_tv_freq,
mp_property_tv_scan). The TV parts remain GPL.
0810e427: could not be reached. Disabled in a previous commit.
43744a2d: unknown author, but this was replaced by dynamic alloc (if the
change is even copyrightable).
116ca0c7: unknown author; reasoning see input.c relicensing commit.
e7e4d1d8: these semantics still exist, but as generic code, and this
code was fully removed.
f1175cd9: the author of the cited patch is unknown, and upon inspection
it turns out that I was only using the idea to pause the player on EOF,
so I claim it's not copyright relevant.
25affdcc: author could not be reached (yet) - but it's only a function
rename, not copyrightable.
5728504c was committed by Arpi (who agreed), but hints that it might be
by a different author. In fact it seems to be mostly this patch:
http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2001-November/002041.html
The author did not respond, but it all seems to have been removed later.
It's a terrible mess though. Arpi reverted the A-V sync code at first,
but left the RTC code for a while. The following commits remove these
changes 100%: 14b35442, 7181a091, 31482783, 614f8475, df58e822.
cehoyos did explicitly not agree to LGPL, but was involved in the
following changes:
c99d8fc8: applied a patch and didn't modify it, the original author
agreed.
40ac0d31: author could not be reached, but all code is gone anyway. The
"af" command has a similar function, but works completely different and
actually reuses a mechanism older than this patch.
54350436: applied a patch, but didn't modify it, except for adding a
German translation, which was removed later.
a2dda036: same situation as above
240b743e: this was made GPL-only in a previous commit
7b25afd7: same as above (for now)
kirijua could not be reached, but was a regular patch contributor:
c2c997fd: video equalizer code move; probably not copyrightable. Is GPL
due to Nick anyway.
be54f481: technically, this became the audio track property later. But
all what is left is the fact that you pass a track ID to it, so consider
the original coypright non-relevant.
2f376d1b: this was rewritten in b7052b43, but for now we can afford to
be careful, so this was marked as GPL only in a previous commit.
43844d09: remaining parts in main.c were reverted in a previous commit.
anders has mostly disagreed with the LGPL relicensing. Does not want
libaf to become LGPL, but made some concessions. In particular, he
granted us permission to relicense 4943e9c52c and 242aa6ebd4. We also
consider some of his changes remaining in mpv not relevant for copyright
(such as 735de602 - we won't remove the this option completely). We will
completely remove his other contributions, including the entire audio
filter chain. For now, this stuff is marked as GPL only. The remaining
question is how much code in player/audio.c (based on the former
mplayer.c and dec_audio.c) is under his copyright. I made claims about
this in a previous commit.
Nick(ols) Kurshev, svn username "nick" and "nickols_k", could not be
reached. He had a lot of changes in early MPlayer. It seems all of that
was removed, at least in mpv. His main work, like VIDIX or libswscale
work, does not exist in mpv anymore, but the changes to mplayer.c and
other core parts still deserve attention:
a4119f6b, fb927549, ad3529b8, e11b23dc, 5f2178be, 93c371d5: removed in
b43d67e0, d1628d12, 24ed01fe, df58e822.
0a83c6ec, 104c125e, 4e067f62, aec5dcc8, b587a3d6, f3de6e6b: DR, VAA, and
"tune" stuff was fully removed later on or replaced with other
mechanisms.
340183b0: screenshots were redone later (the VOCTRL was even removed,
with an independent implementation using the same VOCTRL a few years
later), so not relevant anymore. Basically only the 's' shortcut remains
(but not its implementation).
92c5c274, bffd4007, 555c6766: for now marked as GPL only in a previous
commit.
Might contain some trace amounts of "michael"'s copyright, who agreed to
LGPL only once the core is relicensed. This will still be respected, but
I don't think it matters at this in this case. (Some code touched by him
was merged into mplayer.c, and then disappeared after heavy
refactoring.)
I tried to be as careful and as complete as possible. It can't be
excluded that amends to this will be made later.
This does not make the player LGPL yet.
Nick and kiriuja could not be reached, and created/changed this in
92c5c274, 6441a5ad, bffd4007, 555c6766, c2c997fd. The video equalizer
stuff was redone fully later, but there are still parts that look too
similar and basically use the same approach. I'm more comfortable with
declaring it GPL only for now.
I plan to redo them later in a way that will remove copyright.
cehoyos has not agreed to the LGPL relicensing. He added the deinterlace
property in commit 7b25afd7. Make it GPL-only for now. The still working
parts of the --deinterlace option are not affected by his copyright.
Most contributors have agreed. vo.c requires a "driver" entry for each
video output - we assume that if someone who didn't agree to LGPL added
a line, it's fine for vo.c to be LGPL anyway. If the affected video
output is not disabled at compilation time, the resulting binary will be
GPL anyway.
One problem are the changes by Nick Kurshev (usually using "nick" as SVN
username). He could not be reached. I believe all changes to his files
are actually gone, but here is a detailed listing:
fa1d5742bc: nick introduces a new VO API. It was removed in 64bedd9683.
Some of this was replaced by VOCTRLs are introduced in 7c51652a1b,
obviously replacing at least some functionality by his API.
b587a3d642: nick adds a vo_tune_info_t struct. Removed in 64bedd9683
too.
9caad2c29a: nick adds some VOCTRLs, which were silently removed in
8cc5ba5ab8 (they became unused probably with the VIDIX removal).
340183b0e9: nick adds VO-based screenshots, which got removed in
2f4b840f62. Strangely the same name was introduced in 01cf896a2f again,
but this is a coincidence and worked differently (also it was removed
yet again in 2858232220).
104c125e6d: nick adds an option for "direct rendering". It was renamed
in 6403904ae9 and fully removed in e48b21dd87.
5ddd8e92a1: nick adds code to check the VO driver preinit arg to every
single VO driver. The argument itself and any possibly remaining code
associated with it was removed in 1f5ffe7d30.
f6878753fb: nick adds header inclusion guards. We assume this is not
relevant for copyright.
Some of nick's code was merely moved to other files, such as the
equalizer stuff added in 555c676683 and moved in 4db72f6a80 and
12579136ff, and don't affect copyright of these files anymore.
Other notes:
fef7b17c34: a patch by someone who wasn't asked for relicensing added a
symbol that was removed again in 1b09f4633.
4a8a46fafd: author probably didn't agree to LGPL, but the function
signature was changed later on anyway, and nothing of this is left.
7b25afd742: the same author adds a symbol to what is vo.h today, which
this relicensing commit removes, as it was unused. (It's not clear
whether the mere symbol is copyrightable, but no need to take a risk.)
3a406e94d7, 9dd8f241ac: slave mode things by someone who couldn't be
reached. This aspect of the old slave mode was completely removed.
bbeb54d80a: patch by someone who was not asked, but the added code was
completely removed again.
Merge the pause_player() and unpause_player() functions. Make sure the
pause events are emitted properly. We can now set the internal pause
state based on a predicate, instead of e.g. handle_pause_on_low_cache()
making a mess to trigger the internal pause state as wanted.
Preparation for some more changes.
The plan is to nuke the custom filter chain completely. It's not clear
what will happen to the still needed builtin filters (mostly hardware
deinterlacing and vf_vapoursynth). Most likely we'll replace them with
different filter chain concept (whose main purpose will be providing
builtin things and bridging to libavfilter).
The undocumented "warn" options are there to disable deprecation
warnings when the player inserts filter automatically.
The same will be done to audio filters, at a later point.
Not so important by itself, but important for when we replace the vf
libavfilter wrapper with the common implementation. (Which will
hopefully happen, but not too soon.)
Useful for distinguishing bit depth when hardware decoding. (To the
degree it's useful to show it at all. This just brings the hardware
decoding case on the same level of showing information as the software
decode call.)
Requires a bunch of hacks:
- we access AVFilterLink.hw_frames_ctx. This is not a public API in
FFmpeg and Libav. Newer FFmpeg provides an accessor
(av_buffersink_get_hw_frames_ctx), but it's not available in Libav or
the current FFmpeg release or Libav. We need this value after filter
graph creation, so We have no choice but to access this.
One alternative is making filter creation and format negotiation
fully lazy (i.e. delay it and do it as filters are output), but this
would be a huge change.
So for now, we knowingly violate FFmpeg's and Libav's ABI and API
constraints because they don't provide anything better.
On newer FFmpeg, we use the (quite ugly) accessor, though.
- mp_image_params doesn't (and can't) have a field for the frames
context AVBufferRef. So we pass it via vf_set_proto_frame(), and even
more hacks.
- if a filter needs a hw context, but we haven't created one yet
(because normally we create them lazily), it will fail at init.
- we allow any hw format now, although this could go horrible wrong.
Why all this effort? We could move hw deinterlacing filters etc. to
FFmpeg, which is a very worthy goal.
Cover art handling is a disgusting hack that causes a mess in all
components. And this will stay this way. This is the Xth time I've
changed cover art handling, and that will probably also continue.
But change the code such that cover art is injected into the demux
packet stream, instead of having an explicit special case it in the
decoder glue code. (This is somewhat more similar to the cover art hack
in libavformat.)
To avoid that the over art picture is decoded again on each seek, we
need some additional "caching" in player/video.c. Decoding it after each
seek would work as well, but since cover art pictures can be pretty
huge, it's probably ok to invest some lines of code into caching it.
One weird thing is that the cover art packet will remain queued after
seeks, but that is probably not an issue.
In exchange, we can drop the dec_video.c code, which is pretty
convenient for one of the following commits. This code duplicates a
bunch of lower-level decode calls and does icky messing with this weird
state stuff, so I'm glad it goes away.
Helps with gif, probably does unwanted things with other formats.
This doesn't handle --end quite correctly, but this could be added
later.
Fixes#3924.
If video reaches EOF, subtitle timing will be switched to timing without
video frames. This means it calls osd_set_force_video_pts() and
overrides the PTS of whatever video frame is current (since the video
frame's PTS has nothing to do with the current playback position
anymore).
This was not reset when seeking back into video. Subtitles wouldn't show
up, or if there was a subtitle displayed, it would get stuck with it. In
particular, this could happen even if EOF was only temporary (such as
with --keep-open).
Fix this by clearing the override PTS whenever a video frame is shown.
Fixes#3770.
If a VO is created, but no video is playing (i.e. --force-window is
used), then until now no subtitles were shown. This is because VO
subtitle display normally depends on video frame timing. If there are no
video frames, there can be no subtitles.
Change this and add some code to handle this situation specifically. Set
a subtitle PTS manually and request VO redrawing manually, which gets
the subtitles rendered somehow.
This is kind of shaky. The subtitles are essentially sampled at
arbitrary times (such as when new audio data is decoded and pushed to
the AO, or on user interaction). To make a it slightly more consistent,
force a completely arbitrary minimum FPS of 10.
Other solutions (such as creating fake video) would be more intrusive or
would require VO-level API changes.
Fixes#3684.
when there is a huge delay between audio/video sync, it can take a
really long time to converge back. this speeds up the resync time by
increasing the max_change allowed per iteration.

Move the screensaver enable/disable determination to a central place,
and call it if the stop-screensaver property is changed.
Also, do not stop the screensaver when in idle mode (i.e. no file is
loaded).
Fixes#3615.
If the PTS goes backwards (whether it's a timestamp reset or some other
problem) would just use 0 as frame duration. (At least until the logic
for detecting divergence with the timestamps gets active.)
Trust the demuxer framerate in these cases instead, if it's available. I
think this improves behavior slightly with some broken files.
Move the MPV_LEAK_REPORT env query to mp_create(), where it will also be
used by the client API (it might be helpful, so why not). The same
applies to MPV_VERBOSE.
The prepare_playlist() call doesn't need to be in mp_initialize() and
can just be in mp_play_files() to reduce the size of mp_initialize().
Also, remove wakeup_playloop(), which is 100% redundant with
mp_wakeup_core_cb().
Some properties had a different type from their equivalent options (such
as mute, volume, deinterlace, edition). This wasn't really sane, as raw
option values should be always within their bounds. On the other hand,
these properties use a different type to reflect runtime limits (such as
range of available editions), or simply to improve the "UI" (you don't
want to cycle throuhg the completely useless "auto" value when cycling
the "mute" property).
Handle this by making them always return the option type, but also
allowing them to provide a "constricted" type, which is used for UI
purposes. All M_PROPERTY_GET_CONSTRICTED_TYPE changes are related to
this.
One consequence is that you can set the volume property to arbitrary
high values just like with the --volume option, but using the "add"
command it still restricts it to the --volume-max range.
Also deprecate --chapter, as it is grossly incompatible to the chapter
property. We pondered renaming it to --chapters, or introducing a more
powerful --range option, but concluded that --start --end is actually
enough.
These changes appear to take care of the last gross property/option
incompatibilities, although there might still be a few lurking.
This does 3 kinds of changes:
- change sleeptime=x to mp_set_timeout()
- change sleeptime=0 to mp_wakeup_core() calls (to be more explicit)
- change commands etc. to call mp_wakeup_core() if they do changes that
require the playloop to be rerun
This is preparation for the following changes. The goal is to process
client API requests without having to rerun the playloop every time. As
of this commit, the changes should not change behavior. In particular,
the playloop is still implicitly woken up on every command.
Currently, calling mp_input_wakeup() will wake up the core thread (also
called the playloop). This seems odd, but currently the core indeed
calls mp_input_wait() when it has nothing more to do. It's done this way
because MPlayer used input_ctx as central "mainloop".
This is probably going to change. Remove direct calls to this function,
and replace it with mp_wakeup_core() calls. ao and vo are changed to use
opaque callbacks and not use input_ctx for this purpose. Other code
already uses opaque callbacks, or has legitimate reasons to use
input_ctx directly (such as sending actual user input).
Instead of deselecting the video stream plainly, use the slightly more
robust error_on_track() function. Also give it an error code (although
I'm not sure if this one is confusing, it's better than the one before).
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.
