[Live-devel] AAC Audio

[Bernhard Feiten]

Hi Flaivio,

I attach a file reader I wrote for live.com that reads an extended BSAC-AAC 
elementary stream.
It shows how you can do the read of variable length frames.

For aac it depends if your .aac file conatins MPEG-2 ADTS or ADIF format  or 
MPEG-4 elementary stream.
The attached .aac file is taken from the mp4creator of the MPEG4IP project.
There you can see how these different formats can be handled.

Best regards,
Bernhard
