This should clearly be impossible, but it seems to happen with ordered
chapters for a user.
Since I can't tell what the actual bug is and it seems impossible to
know the details without downloading possibly huge files, this is
probably the best we can do.
Should at least partially fix#1319.
Based on patch by Yuriy Kaminskiy [yumkam gmail].

ALSA returns "FL" as channel layout when trying to play mono. mpv and
libavresample don't like this; in particular, using libavresample to
convert stereo to "FL" fails.
ALSA is crap. It's impossible to make multichannel playback just do the
right thing. dmix (the default on most distros) can do stereo only, and
will refuse to play multichannel. On the other hand, if you try like mpv
(and mplayer) to open a multichannel device (like "surround51" etc.),
this will actually open a hardware device, which will either fail if
dmix is active, or block out dmix if opening succeeds.
This commit falls back to "default" (i.e. dmix) if opening a
multichannel device fails, which is a tiny step towards the right
behavior. (Although fixing it fully is impossible.)
If the user has LEFT/RIGHT/etc. bound in his input.conf, then these were
overriding the menu keys in dvdnav mode.
This hack works because the dvdnav crap happens to be the only user of
MP_INPUT_ON_TOP. If it finds a default key binding in the dvdnav menu
section, it will use that, instead of continuing search and possibly
finding the user key bindings meant for normal playback.
So the OSC will still appear when using --no-input-default-bindings. It
also means it may override a user's mouse_move binding, but I guess
users who don't want the OSC should just use the --no-osc option.
The player thinks an error happened because no audio or video was played
after finishing the file, but this obviously makes no sense with stream
dumping. (error_playing follows the client API convention that negative
values are errors.)
Channel amp otpions were not copied correctly: it copied the size of a
pointer to struct chmap, not the struct itself. Since mp_chmap is
currently 9 bytes, this meant the last channel entry was not copied
correctly on 64 bit systems, leading to very strange failures. It could
be triggered especially when using the client API, because the client
API always copies options on access (mpv command line options tend to
work directly on options).
Ordered chapter EOF was handled as special-case of ending the last
segment. This broke --kee-open, because it set AT_END_OF_FILE in an
"inconvenient" place (after checking for --keep-open, and before the
code that exits playback if EOF is reached).
We don't actually need to handle the last segment specially. Instead, we
remain in the same segment if it ends. The normal playback logic will
recognize EOF, because the end of the segment "cuts off" the file.
Now timeline_set_from_time() never "fails", and we can remove the old
segment EOF handling code in mp_seek().
Running "sub_add file.srt auto" during hook execution automatically
selected the first added track. This happened because all tracks added
with sub_add are marked as "external", and external subtitles are always
selected by default.
Fix this by negating the "external" flag when autoselecting subtitles
during loading. The no_default flag exists for this purpose; it was
probably added for libquvi originally, where we had the same issue.
This could trigger an assertion when using ao_alsa or ao_coreaudio. The
code was simply assuming the number of channel maps was bounded
statically (which was true at first in both AOs).
Fix by using dynamic memory allocation. It needs to be explicitly
enabled by the AOs by setting a temp context, because otherwise the
memory couldn't be freed. (Or at least this seems to be the most elegant
solution.)
Fixes#1306.
If EOF is reached after reading a line, the EOF flag is set. This was a
problem for the m3u code, which checked for EOF _after_ reading a line,
which will discard the last line read.
Also fix a typo in an unrelated part of the file.
MS Windows doesn't allow windows larger than the screen, so we include
a hack to make the window smaller. This hack recenters the window (what
else would it do?).
It didn't account for the virtual offset of the current screen, and it
was reported that it forces the window to the first screen.
Should fix#1292.
The if branch has a weak check to test whether the codec_id is the short
ID, and handles the long IDs in the else branch. The long IDs are all
longer than 12 bytes long, so hardcoding the string offset to get the
trailing part of the name makes sense. But the if condition checks for
another thing, which could get the else branch run even if the codec_id
is short.
Fix the bogus control flow and check if the codec_id is long enough. One
of these checks could be considered redundant, but include them both for
defensive coding.
This is a somewhat obscure situation, and happens only if audio starts
again after it has ended (in particular can happens with files where
audio starts later). It doesn't matter much whether audio starts
immediately or some milliseconds later, so simplify it.
When playing paused, the amount of decoded audio is limited to a small
amount (1 sample), because we don't write any audio to the AO when
paused. The small amount could trigger the case of the wanted audio
being too far in the future in the PTS sync code, which set the audio
status to STATUS_DRAINING, which in turn triggered the EOF code in the
next iteration. This was ok, but unfortunately, this triggered another
retry in order to check resuming from EOF by setting the status to
STATUS_SYNCING, which in turn lead to the busy loop by alternating
between the 2 states. So don't try resyncing while paused.
Since the PTS syncing code also calls ao_reset(), this could cause the
pulseaudio daemon to consume some CPU time as well.
This was caused by commit 33b57f55. Before that, the playloop was merely
run more often, but didn't cause any problems.
Fixes#1288.
