The patch below provides exactly that to the MP3 muxer. A XING header
containing
* the numer of frames,
* the size, and
* a TOC
is generated.
It's based on an idea by Anton Khirnov (restricted to the number of
frames) found at
http://patches.ffmpeg.org/patch/1891/
The TOC is generated as found in lame's "VbrTag.c".
According to my tests the following reproduces the number of frames, the
size and the TOC in "c.mp3" from "b.mp3" (except a shift due to shorter
XING header generated by FFmpeg):
lame -V2 a.wav b.mp3
ffmpeg -i b.mp3 -acodec copy -y c.mp3
This fixes, for instance, the case that there is a track that has some samples with composition time offset and has a track run without sample-composition-time-offsets-present.

Add an extra size validity check in asf_read_frame_header(). Without

As per issue2629, most 23.976fps matroska H.264 files are incorrectly
detected as 24fps, as the matroska timestamps usually have only
millisecond precision.
Fix that by doubling the amount of timestamps inspected for frame rate
for streams that have coarse time base. This also fixes 29.970 detection
in matroska.

While deprecated, they're totally useless as long as their values
are different from the AVIO_FLAG values that are used internally.
Currently, this leads to old libav applications still compiling
correctly (since we haven't removed the fallback wrappers), but
failing since the functions internally compare to the new AVIO_FLAG
values.
These should be removed at some point, but they aren't removed yet.
The intent is to be able to recompile an old application against
the new ABI without modifying the code, and this doesn't work
currently.

read AVI palette from the end of extradata
cosmetics: K&R coding style and more whitespace for Flash Screen Video

It does not make sense (DV is interleaved by design) and
it avoids a crash when the non-interleaved code tries to
use the priv_data of streams created by the DV demuxer.
The crash could be avoided differently, but then that stream
would still lack an index and would not play correctly in
non-interleaved mode.
Fixes e.g. samples/ffmpeg-bugs/roundup/issue1514/Dennis0002_video1.avi
Official AVI specification says that stream header in case of video contains
BITMAPINFO, which is equal to BITMAPINFOHEADER and optional palette. Currently
lavf AVI demuxer thinks otherwise which produces garbage on codecs that have
both palette and extradata (luckily, there are not so many such codecs).
An example of such file is:
http://samples.multimedia.cx/V-codecs/KMVC/baseball1.avi
(IIRC, MSS1 or MSS2 also had such situation but they are still not supported
by lavc).
As a side note, passing palette in extradata as it's been done previously is
not quite correct since proper _extra_ data is surplus bytes in
BITMAPINFOHEADER, not including palette.

This enables non interleaved AVI mode for example.
Players that are picky on strict interleaving can set this.
Patches to only switch to non intereaved AVI mode when the index is not strictly
correctly interleaved are welcome.

If there are no variants, the total bitrate of the single
stream isn't known, and exporting variant_bitrate = 0 does
look weird, since there really aren't any variants.

All file names should be in UTF-8 within libavformat.
This is handled by mapping the open() function to an internal one
in os_support.h for windows.
fopen() could be overridden in the same way, but if that would be
used from ffmpeg.c, it would add a dependency on an ff prefixed
internal lavf function.
