In commit 5f8b060e I blindly assumed that the packet sizes were in
pseudo-samples, but they were actually in bytes. Oops.
(The effect was that cutting the audio was a bit less precise than it
can be.)
Also remove the packet size from ad_spdif.c; it didn't actually use it,
and simply takes what the spdif "muxer" returns.
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.
Needed for the next commit. This commit should probably be reverted as
soon as we're working with full audio frames internally, instead of
"flat" FIFOs.
mpv_opengl_cb_render() is supposed to clear the screen with the
background color if there's no video... I think.
It didn't do this, because although uninit() requested gl_video_config()
to be called, this didn't happen, because this function checks whether
the VO is set - and it's unsert after uninit() releases the lock.
Also call the user wakeup callback in this situation, so the user
actually redraws immediately.
Instead of maintaining a private ring buffer, use the generic support
for audio APIs with pull callbacks (internally called AO pull API). This
also fixes latency calculations: instead of just returning the
ringbuffer status, the audio playback state is calculated better and
includes interpolation.
The main reason this wasn't done earlier was mid-stream format
switching. The pull API can now handle it (in a way) by destroying and
recreating the AO. This is a bit brutal, but quite simple. It's untested
in this new AO, though. Some details might not be right, like how ot
restores the old format when reloading.
This could mute a digital passthrough stream by writing zeros. All other
volume values did nothing.
The comment about MPlayer dying hasn't been true in mpv for quite a
while. It's even possible that it's fixed in upstream MPlayer. mpv will
print a scary error message when trying to change volume with spdif, and
continue normally.
If we really want to mute by writing zeros, we should do it in a
separate filter. But I'm not overly fascinated by this approach; is it
even guaranteed receivers will not be confused by a stream of zeros?
The main reason to remove this is that it's in the way of further
cleanups.
Basically, the idea behind the vp parameter is broken - I guess the
intention was to enable rendering to a specific subrectangle of the
target framebuffer, but there's nothing to specify the actual target
rectangle (the VO will still clear e.g. the borders between video and
framebuffer borders).
We're not going to keep the current semantics either with the upcoming
rework of vo_opengl, so declare this for broken. Maybe we can introduce
a function later which does this properly.
Seems appropriate, and will probably avoid performance surprises with
scary architectures which don't have trivial implementations for atomic
loads. (Consider that demux_mkv calls this very often now, and
libavformat demuxers and streams did this for a while now.)
Check async abort notification. libavformat already do something
equivalent.
Before this commit, the demuxer could enter resync mode (and print silly
warning messages) when the stream stopped returning data because of an
abort.
Do not rely on the pointed-to argument to be initialized; VOCTRLs are
supposed to completely overwrite them on success (or not to touch them
on failure).
The currently only caller of VOCTRL_GET_WIN_STATE initializes the value
before calling this, so this is merely about correctness and didn't lead
to any actual bugs.
This causes the cache to be enabled with --cache=auto. It was not done
previously because the small cache size 320k actually led to worse
performance. However, with the current default cache size of 25000kb,
caching notably improves performance.
Add filter parameters to VAAPI deinterlacing filter to actually process
bottom fields instead of deinterlacing top field twice.

Some UI elements in OS X – like Launchpad and Dock folders – are implemented
using borderless windows in background demonized applications.
When we use these elements, mpv doesn't stop to be the active application, but
the mpv window leaves keyWindow state while we use the OS controls.
This commit just keeps track of window state to update the cursor visibility
accordingly.
Fixes#513
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.
Make MpvEventsView -signalMousePosition a public method so it can be
called without a compiler warning. Previously, the mouse position would
be reported as (0,0) until the cursor was moved.
mpv would attempt to load ICC profiles several times during VO init
even if no window is displayed. This potentially causes it to load
a profile for a different screen than it is going to be displayed
on, thereby invalidating the profile cache and rebuilding the LUT
every single time.
It would not unload a previously loaded profile when the video
window is moved to a display without an installed profile.
Fix these issues and tweak the log messages a little.
A user reported a webm stream that couldn't be played. The issue was
that this stream 1. was on an unseekable HTTP connection, and 2. had a
SeekHead element (wtf?). The code reading the SeekHead marked the
element as unreadable too early: although you can't seek in the stream,
reading the header elements after the SeekHead read them anyway. Marking
them as unreadable only after the normal header reading fixes this.
(The way the failing stream was setup was pretty retarded: inserting
these SeekHead elements makes absolutely no sense for a stream that
cannot be seeked.)
Fixes#1656.
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.
The vaapi equalizer have a custom range, and can have a smaller range
than mpv's normalized video equalizer values. The result is that a vaapi
equalizer value can map to multiple mpv values, so changing a mpv value
by 1 can get "stuck". Fix by remember the mpv value, and returning it if
it still corresponds to the vaapi value.
Really fixes#1647.
(Why am I even bothering with this irredeemable crap?)
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.
Using check_statement() with an empty statement just to check for the
header is quite a hack. Fix check_headers() (so it takes a "use"
parameter), and use it for the checks instead.
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".)
