[vlc-devel] Problem playing h264 + AAC (VBR) in AVI container.

I have a problem reading h264 + AAC AVI files with VLC. The AAC is
VBR. They play very well with VLC 0.8.6i and play perfectly with
MPlayer. But with VLC 1.0.1 it fails to play the audio portion. I have
included VLC messages below that I believe to be pertinent.

These files are created by a surveillance camera and I have some
control over the code or at least some parameters of the encoding and
maybe something might be configured to help compatibility with VLC. I
can't do CBR presently though. Maybe there are VLC options I can try
and play with to see if I can get it to work.

I have read contradicting information on the web about AAC (VBR) in an
AVI. Some say its possible some say not. I hope some of you experts
can shed some light on the subject. If more details is needed, please
let me know. I can also upload an example file to Pasteboard and/or
discuss this on IRC, whichever is easier for you guys.

If you have ideas of things to try to make this work I would appreciate. Thanks!
