This is driving me nuts:
I'm decoding mpegts files, with h264 and either mp2, mp3, or aac audio. The
mpegts files are cut out from mpegts streams from several different sources,
and saved as file.
The decoding containsothing unusual, the standard procedure as in any example.
Works fine on windows (with any of these files), however on OS X Lion audio is
broken (with every of these files). Depending on the audio codec used decoding
succeeds for 50-90% of the audio frames, but for the other 10-50%:
[mp3 @ 0x10a001400] Header missing
or
[mp2 @ 0x105816200] Header missing
or
[aac @ 0x105368800] channel element 0.0 is not allocated
As said, no such messages on windows (exactly the same code) for exactly the
same files, on windows it plays fine.
Examination in a hex editor shows that the mp2/mp3 or aac (adts) frame headers
are there in the source file.
ffplay plays the files on os x without any error.
I see this for the last 3 or 4 months already, and have downloaded and compiled
the latest ffmpeg snapshot several times, replaced all deprecated functions
(such as avcodec_decode_audio3() => avcodec_decode_audio4() ), no change.

The only difference between the windows and the OS X versions is that the
windows versions of ffmpeg are the pre-compiled versions, while on OS X I have
compiled ffmpeg myself.
I went through the code hundreds of times, and i cannot see any reason for this
error on OS X. Any idea or hint how to fix this is very much appreciated!
