Hehe. I'm working on SBR. I've got the code all written but I need to 
get it working and clean it up before I submit it.

There are different ways of signalling SBR within a stream and I think 
one of the types couldn't be decoded by an LC AAC decoder. I'll have to 
check. At least in many cases an SBR stream can be played by an LC AAC 
decoder, it just won't sound as good due to missing high frequencies.

The rtsp stream to which you linked didn't spit any SBR notes though so 
I don't think that's the issue there.
