[FFmpeg-user] What happened to faad/channel element not allocated

[Jon Drukman]

I have a .mov file which shows up with zero audio channels, and produces the
famous "[aac @ 0xad45c60] channel element 1.0 is not allocated" message when
ffmpeg tries to read it.

I found this blog post: http://lzone.de/aac+decoding+with+ffmpeg+doesn%27t+work
which suggests that using libfaad to decode the audio stream will give
satisfactory results.

However, it seems that the current version of ffmpeg does not support libfaad
any more.  There are no faad-related configure options, at least, in a fresh git
checkout.

What can I do to process these files successfully?
