[Live-devel] Multiple Payload Types on RTP (DTMF Support)

[Ross Finlayson]

FYI, the way we will be implementing this (In the released "LIVE555 
Streaming Media" code) will be to update the "RTPInterface" and 
"MultiFramedRTPSource" classes to handle the reception of more than 
one RTP payload type on the same network interface (and 
demultiplexing to the appropriate "RTPSource" object, based on the 
RTP payload type code).  Also, we'll update the "MediaSession"  code 
to recognize and handle more than one payload format code in a SDP 
"m=" line.

Then, specifically for DTMF, we'll define and implement new 
"DTMFRTPSource" and "DTMFRTPSink" classes.

(I.e., DTMF will use the existing source->sink mechanism, without change.)
