Playing AVI files containing B-frames with demux_lavf printed two
"decreasing pts" info messages at the start of the file. We know the
timestamps from AVI won't be valid pts, so add a demuxer field to
convey that information to the timing code and make that not even try
to use the timestamps as valid pts.
demuxer_get_current_chapter() accessed sh_video/sh_audio pts fields to
determine playback position. demux layer shouldn't access those and
the values used weren't quite correct anyway. Give the playback
position as a parameter to the demux layer function instead. Also
change the top-level get_current_chapter() to use get_current_time()
in the timeline case where it didn't refer to demux layer.
"libavformat file format detected" wasn't a very useful message due to
the many file formats supported to libavformat. Change the message so
that for demux_lavf it says something like
"Detected file format: QuickTime/MPEG-4/Motion JPEG 2000 format (libavformat)"
(using long name from FFmpeg), and for non-lavf something like
"Detected file format: Matroska".
When -alang / -slang was specified the numerically first matching
track (if any) was always chosen. This meant that specifying "-alang
eng" could change the track choice even if all tracks were in English,
because now the default flag of tracks was ignored. Change the logic
to take the default flag into account as a secondary sorting key.
The code also accepted prefix matches, so that "-slang g" would match
track language "ger". I think that was not intentional. Change it to
require exact matches.
Move functions to query current playback position, percentage position
and total video length from from the demuxer layer to top level. The
functions need access to playback state that doesn't belong on the
demuxing level. Make the new functions more capable and simplify some
code that can now rely on them. This fixes some errors in displayed in
OSD and slave mode information when using timeline (ordered chapters).
FFmpeg increased the amount of padding that must be readable beyond
input buffers without SIGSEGV from 8 to 64, and the MPlayer value must
be changed accordingly.
These functions return void*, which is compatible with any pointer,
so there is no need for casts.

Change the demuxer_add_attachment() and demuxer_add_chapter()
functions to take a length argument for various name strings, so those
strings do not need to be 0-terminated. This will make it easier to
directly pass demuxed data without first making a copy just to add
0-termination. Also allocate the struct demuxer data structures for
attachments and chapters with talloc.
via libavcodec.
Parsing can be done at the demuxer stage (currently disabled) or at the decoder
(ad_ffmpeg, enabled).
Should allow using the libavcodec AAC, DTS, ... decoders independent of container
format.

-audiofile by moving the code to manually interleave
subtitles to mp_common.c.
video.c should still be changed to not be demuxer-specific
anymore, it is bad practice but fully fixing it is non-trivial.

Remove the "num_chapters" and "mode" parameters that aren't needed by
any callers. Change "float *seek_pts" to "double *". Allocate the
string returned via "chapter_name" with talloc.
When the new mode is active relative seeks are converted to absolute
ones (current video pts + relative seek amount) and forward/backward
flag before being sent to the demuxer. This mode is used if the
demuxer has set the accurate_seek field in the demuxer struct and
there is a video stream. At the moment the mkv and lavf demuxers
enable the flag.
This change is useful for later Matroska ordered chapter support (and
for more general timelime editing), but also fixes problems in
existing functionality. The main problem with the old mode, where
relative seeks are passed directly to the demuxer, is that the user
wants to seek relative to the currently displayed position but the
demuxer does not know what that position is. There can be an arbitrary
amount of buffering between the demuxer read position and what is
displayed on the screen. In some situations this makes small seeks
fail to move backward at all (especially visible at high playback
speed, when audio needs to be demuxed and decoded further ahead to
fill the output buffers after resampling).
Some container formats that can be used with the lavf demuxer do not
always have reliable timestamps that could be used for unambiguous
absolute seeking. However I made the demuxer always enable the new
mode because it already converted all seeks to absolute ones before
sending them to libavformat, so cases without reliable absolute seeks
were failing already and this should only improve the working cases.
Firstly 32 MB is not that much with HD video and the different
values depending on whether CONFIG_TV_BSDBT848 is set or not
makes debugging harder.

The hard limit on the amount of buffered bytes per demuxer stream had
not been increased since 2001. Since then there have been significant
increases in both video bitrates (so it's easier to hit the limit) and
typical memory available on a computer (so there's less reason to
limit the memory used for buffering). The 8 MiB limit was too easy to
hit in the case of high-bitrate video lagging behind audio, when the
file is demuxed ahead to get audio packets but video has to be
buffered until the decoder catches up to that point.
Increase the limit to 128 MiB and remove the #ifdef for
CONFIG_TV_BSDBT848 because the normal limit is now higher than the
increased value under the #ifdef.
