In gstreamer, a "chunk" of mpeg audio might be the same as a "mpeg 
frame" (header + data section)?  If so, then it would seem the chunks 
could be passed accross with rtp directly in individual packets. 
Exchanging extended type information could be done in special packets, 
or through a secondary protocol. That would also look much more like 
"gstreamer" over rtp than "mpeg" or a specific encoded format over rtp.
