[FFmpeg-devel] [RFC/PATCH] Dealing with 0 padded audio packets

[Alex Converse]

Currently the FFmpeg stumbles when decoding AAC where the container
has zero padded audio frames to make a constant packet size. This
situation is common for AAC in ASF[1] and WMP handles it fine.
QuickTime seems to handle the MP4 analog fine.

The best idea I can come up with is a chomp[2] bitstream filter to
trim these when remuxing and to make the AAC decoder consume the rest
of a packet if it is all zero.

Other ideas are welcome.
