[Live-devel] Problems with Streaming of AMR

[Ross Finlayson]

>Is the frame header restored after streaming over RTP?

No, not by default.  However, the frame header byte is available - 
from the "AMRAudioRTPSource" - using the "lastFrameHeader()" member 
function.

See, for example, the code for "AMRAudioFileSink".  If you feed your 
incoming data (from "AMRAudioRTPSource" into an "AMRAudioFileSink", 
you'll end up with an AMR-format data file that you should be able to 
play using QuickTime Player (for example).

That's a FFMPEG-related question; you're going to have to figure that 
out yourself from looking at the code.  I haven't yet used FFMPEG at 
all to *decode* AMR audio.
