[Live-devel] Question about "MP4A-LATM" and "mpeg4-generic".

Because different organizations (perhaps for political reasons, I'm 
not sure) came up with different RTP payload formats for streaming 
the same type of data (MPEG-4 audio).

They're different RTP payload formats.  The former is described in 
RFC 3016 (and implemented by us in the "MPEG4LATMAudioRTPSink" and 
"MPEG4LATMAudioRTPSource" classes); the latter is described in RFC 
3640 (and implemented by us in the "MPEG4GenericRTPSink" and 
"MPEG4GenericRTPSource" classes).
