Hi chiayu,

you are completely right. That cannot work per specification but Magnus who 
implemented it tested it to my knowledge on Windows and it seems to work on 
windows nevertheless (He is a C++ guy just having a vacation in Java land). 
Hmmmm - what ever. I changed it to use mark() and reset() and added a test. I 
will change the implementation to use Channels and NIO as the rest of the code 
in the next days (It's good work for a 4h flight on Saturday). 
The preliminary fix is in the trunk. I don't want to release it in this state, 
I want to fix the other implementations (e.g. H264) first.

Best Regards,
Sebastian

Should be done for all except EC3Track. I'll close that issue now since AAC - 
which is the ticket about - is done.
