audio corruption streaming mp4a over rtp to DSS

Description

Tested with NB win32 trunk-20080512-0003. Also reported to fail with current git master.

The stream is reflected through a Darwin Streaming Server.

:sout=#transcode{vcodec=mp4v,vb=512,acodec=mp4a,ab=64,channels=2}:rtp{mp4a-latm,port-video=1240,port-audio=1238,dst=SERVERIP,ttl=12,sdp="file:///test.sdp"}

The problem seems to be in the rtp with mp4a combination. The audio gives some stuttering/crackling effect on the decoding side with occasional faad messages:

faad warning, array index out of range
faad warning, bitstream value not allowed by spec

http/ts and udp/ts output with mp4a is ok. Changing mp4a to mp3 also works fine. The same commandline using 0.8.6f does not have this problem.

So, I guess this is a regression.
