[Live-devel] Query on AMRDeinterleaver::deliverIncomingFrame

No.  Although our current implementation supports only the 
transmission of only one AMR frame in each RTP packet 
("AMRAudioRTPSink"), it *does* support the reception (and 
deinterleaving) of multiple frames in each RTP packet.  It does this 
by redefining the virtual function "nextEnclosedFrameSize()" (in the 
class "AMRBufferedPacket").  Because of this, each "RawAMRRTPSource" 
delivers only one AMR frame at a time to its downstream object (an 
"AMRDeinterleaver"), regardless of how many AMR frames were actually 
present in the incoming RTP packet.
