demuxer.c calls demuxer->close() even if opening failed. Thus the
mkv_free() call added in 0ece360eea ("demux_mkv: skip files faster
in ordered chapter file search") was wrong, and could cause a crash
from a double free if some data structures were allocated before the
opening attempt was aborted.
Ordered chapter code tries opening files to find those matching the
SegmentUID values specified in the timeline. Previously this scan did
a full initialization of the Matroska demuxer for each file, then
checked whether the UID value in the demuxer was a match. Make the
scan code instead provide a list of searched-for UIDs to the demuxer
open code, and make that do a comparison against the list as soon as
it sees the UID in the file, aborting if there is no match.
Also fix units used in "Merging timeline part" verbose message.
Rename the BSTR() function to bstr(). The former caused a conflict
with some Windows OS name, and it's no longer a macro so uppercase
naming is less appropriate.
If the played file has per-track titles for audio and subtitles show
those on the OSD when switching tracks. This changes the OSD message
from 'Audio: (2) eng' to 'Audio: (2) eng ("Director's commentary")'.
Remove code that tries to select audio track during demuxer
initialization from demux_mkv and demux_lavf. Just leave audio
disabled at that point; the higher-level select_audio() function will
call the demuxer to switch track later anyway.
Removing this unneeded code also fixes use of these demuxers as the
main demuxer with -audiofile. Before the automatic track selection
would have enabled an audio track (if the file had any); as the main
demuxer was not used for audio the unused packets from this enabled
track would accumulate until they reached queue size limits.
Commit de42015a97 ("demux_mkv: read tags") added code that
failed to initialize a loop variable. Fix. No visible problems caused
by the bug have been reported.
Duration may now be set for packet types other than subtitles; as far
as I can tell nothing should care. A check requiring valid duration
values for subtitles is removed, because duration may not be properly
set for all bitmap subtitle types; hopefully this doesn't make the
behavior with (already broken) subtitles without duration worse.
demux_mkv kept various integer timestamps in millisecond units.
Matroska timestamp arithmetic is however specified in nanoseconds
(even though files typically use 1 ms precision), and using ms units
instead of that only made things more complex. Based on the demux_mkv
example the general demuxer-level chapter structure also used ms
units. Change the demux_mkv arithmetic and demuxer chapter structures
to use nanoseconds instead. This also fixes a seeking problem in
demux_mkv with files using a TimecodeScale other than the usual
1000000 (confusion between ms and TimecodeScale*ns units).
Make seeks backward from a time before the first index entry go to the
first entry instead of failing completely. This change doesn't affect
behavior for most files, because seeks are clamped to 0 from below and
normally files have the first index entry at 0.
Use the value of the OutputSamplingFrequency element instead of the
SamplingFrequency element as the "container samplerate". In most cases
this only removes a warning, as those typically differ for SBR AAC
files and there was already a special case detecting this in
ad_ffmpeg.
The implementation adds a new "container_out_samplerate" field to the
sh_audio struct. Reusing the existing "samplerate" field and the
equivalent inside the 'wf' struct and just setting those to the new
value instead would probably work (at least I'm not aware of any codec
that would need the original SamplingFrequency for initialization).
However using a separate field also avoids some ugliness: the 'wf'
struct may not exist (though most demuxers create it), and the
'samplerate' field is overwritten to reflect the final value decided
by codec when decoding is first initialized.
Due to a bug created back in 2006 when SimpleBlock support was added,
demux_mkv demuxed one audio packet from the initial file position
after a seek, then skipped the following ones until a video keyframe
was found. This wasn't very noticeable earlier, but it had bad effects
after the recently added -initial-audio-sync code as the extra packet
with an earlier timestamp confused timing calculations and resulted in
desync after seeking. Fix.
Commit fc66c94360 ("demux_mkv: seek: with no track-specific index
entries use any") used uint64_t for a variable that should have been
int64_t. Fix. The practical effects of this error were minor; mainly
it made the player unnecessarily read the file contents between the
previous index entry and the correct one when seeking.
The Cue entries in typical Matroska files have information for the
video track only. This caused seeks to fail when playing with
-novideo, as demux_mkv tried to use audio track index entries then.
Add a fallback case that uses any index entries without caring what
track they're for if there are no entries specific to the track we're
interested in.
Relative seeks didn't add the current position as they should. Fix.
Note that this had no effect in normal playback case even if the file
had no index, because the "accurate_seek" logic at higher level would
convert all commands to absolute seeks before calling demuxer level.
Add some checks to prevent bad files from creating arbitrarily large
buffer blocks (which could result in integer overflows and memory
corruption). Remove a test with little use from demux_mkv_decode(); it
compared an int with size_t, and was useless on 64-bit platforms at
least.

Assume files which start with an EBML header but have no DocType
element in that header have type "matroska", and attempt to play
them. Reportedly some mkvmerge versions create such files.
Change demux_mkv to behave by default as it did with -idx before. The
index generation code in demux_mkv linearly scans the file up to the
seek timestamp (it doesn't read the whole file up front like some
other demuxers do). Doing that is probably a better default for files
with no index than rejecting the seek request and asking user to
specify -idx.
Commit fc39d48465 ("demux_mkv: store streams sequentially in
demuxer->[avs]_streams") had a copy-paste error causing it to look up
a video ID where it should have been an audio one. The most likely
visible symptom was a segfault when seeking while playing a
high-numbered audio track. Looks like I was careless with that
original commit, second bug in the same one...
Change 'struct vf_instance' pointer arguments to more standard style
as in the subject. Also some other minor formatting fixes.
Patch by Diego Biurrun.
The code handling larger-than-minimum realvideo extradata sizes was
complete nonsense. It tried to add the additional data to the exported
track extradata by reading data from the input stream, which was
completely bogus as this code is called long after the original
Matroska track extradata information has been read. As a result the
data read had nothing to do with correct values, and the read call
messed up the stream position which likely broke further parsing of
the file and caused complete playback failure. Change the code to
instead copy any additional part at the end of input extradata to the
end of output extradata. I believe this is the intended semantics,
though I haven't verified it from any specs.
Commit fc39d48465 ("demux_mkv: store streams sequentially in
demuxer->[avs]_streams") had a simple bug in automatic stream
selection causing a crash if no video or audio track was marked as
'default'. Fix.
Allow audio stream switching to turn off sound or enable it, and also
include nosound as one of the values cycled through when stepping to
the next audio stream.
demux_mkv used the Matroska TrackNumber as the array offset in demuxer
stream lists. The TrackNumber entry stored in the file can be an
arbitrary 64-bit value, and some of the code could try reading from
the arrays with that offset, causing a crash if the file had insane
values. Fill the arrays sequentially instead. Also add some checks to
make the handling of too high stream counts more robust.
Move "struct bstr" definition from ebml.h to its own header and add
some utility functions/macros. Change length field type from int to
size_t and adjust using code accordingly.
Partially based on a patch from Anton Khirnov.
Convert demux_mkv_decode() to allocate possible new storage with
talloc and fix a talloc/malloc conflict in demux_mkv_open_sub() that
broke decoding of files which had a subtitle track with compressed
private data.
Add support for compression algorithm 3 (header stripping). Rewrite
some of the code related to handling manyfold compression, it was just
completely broken (I don't have samples to test whether it actually
works now).
The decompression step wasn't run at all for subtitle types other than
vobsub. Fix that. Remove a "!mkv_d->v_skip_to_keyframe" test from the
subtitle handling - for properly timed subtitles unnecessary packets
do little harm, and the subtitles could stay visible.
