Precise seeking requires skipping audio, since the demuxer usually
doesn't seek precisely enough. There is a sanity check that prevents
skipping more than 300 seconds of audio. This still fails with very
large mp3s. For example, with a 1GB sized mp3 with Xing headers, entries
will be 4 MB apart on average, and occasionally much more.
Just bump the limit. I'm not even sure why it was added in the first
place; I suppose it's most important for files with real PTS resets.
"Non-monotonic" isn't even 100% correct; it's missing "strictly" (for
briefness I guess), and also the message is printed if the PTS jumps
forward. So just print something that is likely a bit easier to
understand.
Unlike other VOs, this rendered OSD even while no VO was created
(because the renderer lives as long as the API user wants). Change this,
and refactor the code so that the OSD object is accessible only while
the VO is created.
(There is a short time where the OSD can still be accessed even after VO
destruction - this is not a race condition, though it's inelegant and
unfortunately unavoidable.)
For some reason there were two points in the code where it warned
against non-monotonic video PTS. The one in video.c triggered on PTS
going backwards or making large jumps forwards, while dec_video.c
triggered on PTS going backwards or PTS not changing. Merge them into a
single check, which warns against all cases.
There was a somewhat obscure optimization in the OSD and subtitle
rendering path: if only the position of the sub-images changed, and not
the actual image data, uploading of the image data could be skipped. In
theory, this could speed up things like scrolling subtitles.
But it turns out that even in the rare cases subtitles have such scrolls
or axis-aligned movement, modern libass rarely signals this kind of
change. Possibly this is because of sub-pixel handling and such, which
break this.
As such, it's a worthless optimization and just introduces additional
complexity and subtle bugs (especially in cases libass does the
opposite: incorrectly signaling a position change only, which happened
before). Remove this optimization, and rename bitmap_pos_id to
change_id.
This caused complaints because the fps was basically rounded on
microsecond boundaries in the vsync interval (it seemed convenient to
store only the vsync interval). So store the fps as float too, and let
the "display-fps" property return it directly.
Requested change in behavior.
Note that we set the assumed "infinite" display_fps to 1e6, which
conveniently lets vo_get_vsync_interval() return a dummy value of 1,
which can be easily checked against, and still avoids doing math with
float INFs.
Starting to get tired of seeing the full config.h in verbose output
every time. Make it slightly more elegant by outputting the list of
satisfied dependencies instead.
Instead of refusing to set properties like "fullscreen" if no VO was
created, always allow it. So if no VO is created, setting the property
merely changes the options (and will be applied once the VO is created).
This is consistent with similar behavior changes to some other
properties.
Improves the behavior reported in #1676.
Also, we shouldn't check the config_ok variable - the VO should do this.
mpctx->filename is obviously not set if no file is playing.
When this code was written, it probably couldn't happen, because the
normal screenshot path fails much earlier in idle mode. But you can
still take screenshots in "full window" mode, and recently the
screenshot code was changed to use the "full window" mode if the normal
path does not work.
When playback is started after seeking or opening a file, we need to
make sure audio and video line up exactly. This is done by cutting or
padding the audio stream to start on the video PTS.
This does not quite work with spdif: audio is compressed data, within a
spdif frame. There is no way to cut the audio "in between" the frames.
Cutting between the frames would just produce broken spdif packets, and
who knows how receivers will react to this (play noise?). But we still
can cut it in frame boundaries.
Unfortunately, we also insert 0 data for "silence" - we probably
shouldn't do this. Chances are the receiver will switch to PCM or so.
But for now this will have to do.
Note that this could be simplified somewhat, as soon as we work with
frames. See previous commit.
Handle the failure gracefully, instead of exploding and disabling audio.
Just set the speed back to 1.0.
Also remove the AF_DETACH from af_scaletempo. This actually created a
dangling pointer in af_add(), a tricky consequence of af_add()
reconfiguring the filter chain and the newly added filter using
AF_DETACH. Fortunately the AF_DETACH is not needed (and probably never
worked - it comes from MPlayer times, and MPlayer also disables audio
when trying to change speed with spdif).
Always use af_scaletempo if it's inserted, even if the option
--audio-pitch-correction=no is set.
Make sure all filters are reset on speed change. It's conceivable that
dynamic changes to the filter chain at runtime leave filters around
without resetting their speed parameters.
Also move the code to a separate function.
The global unpack function got moved to table.unpack in Lua 5.2, and
it's only available as the global if 5.2 is built with compatibility
enabled (the default). Lua 5.3 does not build with 5.1 compatibility by
default.
Fixes#1648.
If the audio decoder was created, but no audio filter chain created yet
(still trying to decode a first audio frame), setting the "speed"
property could explode. It tried to recreate the filter chain, even
though no format was set yet.
This is inconvenient and should not happen.
main() being called with argc==0 is probably possible. Fix by skipping
the program name early. (I already changed and reverted this once, but
this time we make sure that it's less likely to confuse the skipped argv
with main()'s argv by naming it "options".)
Move the command line parsing and some other things to the common init
routine shared between command line player and client API. This means
they're using almost exactly the same code now.
The main intended side effect is that the client API will load mpv.conf;
though still only if config loading is enabled.
(The cplayer still avoids creating an extra thread, passes a command
line, and prints an exit status to the terminal. It also has some
different defaults.)
This gets rid of the need for a second (or more) parameters; instead it
can be all in one parameter. The (now) redundant parameter is still
parsed for compatibility, though.
The way the flags make each other conflict is a bit tricky: they have
overlapping bits, and the option parser disallows setting already set
bits.
Although the libraries we use for resampling (libavresample and
libswresample) do not support changing sampelrate on the fly, this makes
it easier to make sure no audio buffers are implicitly dropped. In fact,
this commit adds additional code to drain the resampler explicitly.
Changing speed twice without feeding audio in-between made it crash
with libavresample inc ertain cases (libswresample is fine). This is
probably a libavresample bug. Hopefully this will be fixed, and also I
attempted to workaround the situation that crashes it. (It seems to
point in direction of random memory corruption, though.)
It was possible to make the player play local files by putting rar://
links into remote playlists, and some other potentially unsafe things.
Redo the handling of it. Now the rar-redirector (the thing in
demux_playlist.c) sets disable_safety, which makes the player open any
playlist entries returned. This is fine, because it redirects to the
same file anyway (just with different selection/interpretation of the
contents). On the other hand, rar:// itself is now considered fully
unsafe, which means that it is ignored if found in normal playlists.
When used with mp.get_screen_size(), mp.get_screen_margins() allows a
Lua script to determine what portion of the mpv window actually has the
video in it.
Broken drivers are an issue rather often. Maybe this gives the user an
idea that this could be the reason. (We can't dump much more info on a
80x24 terminal.)
This option allows the user to pass non-supported options directly to
youtube-dl, such as "--proxy URL", "--username USERNAME" and
'--password PASSWORD".
There is no sanity checking so it's possible to break things (i.e.
if you pass "--version" mpv exits with random JSON error).

A while ago, we made mpv output the native number of channels by
default, instead of stereo. I assumed this was not wanted for encode
mode.
This commit keeps the assumption, but allows setting the number of audio
output channels at all, instead of always forcing stereo. (Pretty much a
hack.)
Commit f54220d9 attempted to improve this, but it got worse. Now there
was a crash when ytdl_hook.lua added external tracks. This happened
because close_unused_demuxers() assumed that sources[0] was the main
demuxer (so that it didn't close it). This assumption failed, because
the ytdl script can add external tracks before the main file is loaded.
The easy fix would have been to check for master_demuxer, and not i==0.
But instead give up on the old idea, make some stricter assumptions how
demuxers and external tracks map, and simplify the code.
