Frame rate information is mostly irrelevant for playback, but it's
needed at least to convert frame numbers used in some subtitle formats
(like MicroDVD) into timestamps. Libavformat stopped making up a frame
rate if no "reliable" information is available (commit 7929e22bd
"lavf: don't guess r_frame_rate from either stream or codec timebase",
1.5 months ago). This caused a regression with AVI files and MicroDVD
subtitles. Add a heuristic similar to what libavformat used to have,
to make up FPS values which should work at least for the AVI+MicroDVD
use case.
demux_lavf was returning a static size value when libavformat queried
file size with AVSEEK_SIZE. Add code to query the stream for possibly
changed value first. This at least improves seeking with growing MPEG
files; before seeks would never go beyond the part of the file that
existed when the stream was first opened.
Change demux_lavf to use CodecID -> RIFF tag mappings that are now
available through the public Libav API. Previously it used a copy in
ffmpeg_files/taglists.c. That can now be deleted.
Change various code to use the latest Libav API. The libavcodec
error_recognition setting has been removed and replaced with different
semantics. I removed the "--lavdopts=er=<value>" option accordingly,
as I don't think it's widely enough used to be worth attempting to
emulate the old option semantics using the new API. A new option with
the new semantics can be added later if needed.
Libav dropped APIs that were necessary with all Libav versions
until quite recently (like setting avctx->age), and it would thus not
be possible to keep compatibility with previous Libav versions without
adding workarounds. The new APIs also had some bugs/limitations in the
recent Libav release 0.8, and it would not work fully (at least some
avcodec options would not be set correctly). Because of those issues,
this commit makes no attempt to maintain compatibility with anything
but the latest Libav git head. Hopefully the required fixes and
improvements will be included in a following Libav point release.
Update various code using Libav libraries to remove use of API
features that were deprecated at Libav release 0.7. I think this
removes them all with the exception of URLContext functions still used
in stream_ffmpeg.c (at least other uses that generated deprecation
warnings with libraries from 0.7 are removed).
Require versions of the Libav libraries corresponding to Libav release
0.7. These are:
libavutil 51.7.0
libavcodec 53.5.0
libavformat 53.2.0
libswscale 2.0.0
libpostproc 52.0.0
Also disable the fallback to simple header check if these libraries
could not be found with pkg-config; now compiling without pkg-config
support for these always requires explicitly setting --enable-libav
and any needed compiler/linker flags. The simple check would have let
compilation proceed even if a version mismatch was detected.
Libav stopped automatically filling missing codec_tag field for raw
codecs based on pix_fmt in libav commit bb416bd68c ("lavf: do not set
codec_tag for rawvideo"). This broke demux_lavf for raw video in
formats like YUV4MPEG, as the video format was not exported from
demux_lavf in any form (the information only existed in the pix_fmt
field of the struct AVCodecContext from libavformat, and that is not
exported). Add an explicit call to avcodec_pix_fmt_to_codec_tag() to
set the codec tag again so that selecting the correct raw decoder
based on the tag works.
Commit 6e8d420a41 ("demux: avoid a copy of demux packets with lavf,
reduce padding") was missing an av_dup_packet() line. As a result at
least formats that use parsing on the lavf side could fail (with
parsing the packet may contain pointers to temporary fields that
will be overwritten/freed when reading further packets, and
av_dup_packet() is required to allocate permanent storage).
When demux_lavf read a new packet it used to copy the data from
libavformat's struct AVPacket to struct demux_packet and then free the
lavf packet. Change it to instead keep the AVPacket allocated and
point demux_packet fields to the buffer in that.
Also change MP_INPUT_BUFFER_PADDING_SIZE to 8 which matches
FF_INPUT_BUFFER_PADDING SIZE; demux_lavf packets won't have more
padding now anyway (it was increased from 8 earlier when
FF_INPUT_BUFFER_PADDING_SIZE was increased in libavcodec, but that
change was reverted).
Don't interpret native MPEG codec tags using our generic
format-agnostic codec tag tables. MPEG may use tag 3 for MP3, whereas
the generic tables map 3 to uncompressed PCM. Make the code ignore the
codec_tag field for the "mpeg" and "mpegts" libavformat demuxers and
rely on the codec_id value provided by lavf only.
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.
Do the global initialization of libavcodec and libavformat
(avcodec_register_all(), av_register_all()) immediately on program
startup and remove the initialization calls from various individual
modules that use libavcodec/libavformat functionality.
Setting AVIOContext for AVFMT_NOFILE formats now triggers a warning
from libavformat (and triggered an error for a while), so add a check
to avoid setting AVIOContext when not necessary.

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")'.
Update various code to use newer alternatives instead of deprecated
functions/fields that are being dropped at libav API bump. An
exception is avcodec_thread_init() which is being dropped even though
it's still _necessary_ with fairly recent libav versions, so there's
no good alternative which would work with both those recent versions
and latest libavcodec. I think there are grounds to consider the drop
premature and revert it for now; if that doesn't happen I'll add a
version-test #if check around it later.
libavformat returns nonsense per-stream bitrate values for some MPEG
files (0 or many times higher than the overall bitrate of the file),
which triggered the heuristic to enable byte-based seeking in
demux_lavf and then made the byte-based seeks wildly inaccurate.
Disable the support for byte-based seeks. This will avoid problems
with files that have consistent timestamps, but on the other hand will
completely break seeking in MPEG files that have timestamp resets.
I'll probably add at least an option to manually enable byte-based
seeking later.
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.
In 59058b54a7 (from svn r31129) Aurelien
changed demux_lavf -vid indexing, but failed to change the initial
video stream selection based on -vid to match. Fix.
If the argument given to demux_lavf audio/video switch code is not one
of -2, -1, or valid audio/video ID the code will treat it the same as
-2 (switch to no sound / no video). However the returned index was not
set to -2 in this case. Fix. Also change the returned index from -1 to
-2 when staying at no sound / video.

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).
When trying to determine the format of an input stream, demux_lavf
retries the probe with a larger buffer size up to some limit if the
match score is low, but when reaching the size limit it accepted the
best match (if any) regardless of its score. Change it to require a
score of at least AVPROBE_SCORE_MAX/4 to accept a match at all.
Commit 91ea30c585 ("demux_lavf: use lavf for all formats except those
listed") broke handling of files whose type libavformat couldn't
recognize at all. Fix the demux_lavf probe function to correctly
return failure in that case.
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.
lavf demuxers are mostly better and receive more maintenance,
therefore it makes sense to prefer them in most cases. Change the
"preferred" logic from listing all formats for which lavf is preferred
to listing exceptions for which it isn't. Currently there are 3
exceptions: Matroska, FLAC and RealMedia (.rm).
"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".
Seeking in MPEG files with pts resets could fail completely, as it was
always done by timestamps and those of course don't unambiguously
specify a file position in such files. Add basic functionality for
byte-based seeking and playback position reporting, and decide whether
to use that functionality based on a simple heuristic (could be
improved).
When playing avi files take timestamps from the .dts field of the
packet instead of .pts. For avi libavformat returns the original avi
timestamps in .dts; without GENPTS set .pts is sometimes unset, with
GENPTS set it'll contain some made up values which are not correct
pts. Current libavformat also has a bug take makes it loop over the
whole avi file if you use GENPTS with video streams disabled.
The timing code can cope with the avi timestamps even though they're
not really pts.
Some internet radio streams are ogg/vorbis with a new stream for each
track (and the previous stream stops receiving data). Add a hack to
ignore the stream number in packets when input seems to match this
case; all packets will be effectively regarded as parts of the same
audio stream. This workaround can't work perfectly with current lavf
because it will keep adding streams and then hit its 20 stream
maximum; at that point playback will likely fail. Print a warning
about this problem and mention "-demuxer ogg" as a possible
workaround.
Currently there's no check that the vorbis extradata is actually
compatible between the streams.
AVInputFormat name fields consist of comma-separated components, more
of which may be added in backwards-compatible versions. demux_lavf did
a strcmp against the whole field at once; this would break if a
component was added. Change the code to search for individual
component matches within the field instead.
