That should work, provided that the input AC3 data is in the format that 
"AC3AudioStreamFramer" expects (the same data format that comes from a 
".vob" file, for example), and has 'stream code' 0x80 (the default 
parameter value).

Note, though, that "AC3AudioRTPSink" (and "AC3AudioRTPSource") have not 
kept track of recent changes to the AC3 RTP payload format that's currently 
being standardized in the IETF.  If you use the current "AC3AudioRTPSink", 
then you won't be able to receive/play the stream with anything other than 
"VLC" or "MPlayer" (which both use the current "AC3AudioRTPSource").
