[MPlayer-dev-eng] AAC decoding is out of sync

[Dan Oscarsson]

Upgrading from the source snapshop of 2010-03-06 to current shows that
changes have been done to AAC decoding and ffmpeg is tried before faad.

But now playing a DVB-T mpeg-ts stream with h.264 and AAC results in
audio being out of sync with video (status line says it is in sync but
you hear it is out of sync).

If I manually add -ac faad audio is in sync.

Also I not that if you seek in file when -ac faad is not used, A-V value
gets very much out of sync on status line, but not the audio.

So what is changed? It worked fine in the 2010-03-06 version.

Without -ac faad mplayer says:

With -ac faad I get:

What happens without -ac faad, does ffmpeg take over entire decoding?
I cannot see any big changes in the libmpdemux/libmpcodec directories so
I assume it has to do with ffmpeg.

The smallest sample I have where you can see a person talk and hear that
audio is out of sync is about 90 MB.
