I raised this issue sometime ago, it was fixed, but has at some stage

Previous post:

Previous fix:

The problem is caused if ffmpeg sets the average bit rate (avgBitrate )
in the DecoderConfigDescriptor within the esds atom to zero. Where the
avgBitrate is a non zero value, the m4a files play OK.

Noticed the problem last week when I changed from Ubuntu 10.04 (Lucid)
to Ubuntu 12.04 (Precise).

Ubuntu 10.04 (Lucid) ffmpeg 4:0.5.9-0ubuntu0.10.04.3  
Ubuntu 12.04 (Precise) fmpeg 4:0.8.5-0ubuntu0.12.04.1

Can you please refix?
