My question is about using gstrtbin for multicast streaming.
To adapt the examples from gst-plugins-good/test/examples/rtp/, such as 
server-v4l2-H264-alsasrc-PCMA.sh and client-H264-PCMA.sh, is it 
sufficient to specify the "multicast-group" and "multicast-interface" 
properties on the client's udpsrc elements and in the server use the 
multicast-group address as the udpsink elements' host property? Will 
rtp/rtcp still work properly for the case where i have one server and 
two or more clients? I've tested this out on a three machine setup and 
wireshark tells me that each client is sending receiver reports and that 
the server is sending sender reports, and in general it looks fine. I 
just wanted to make sure I wasn't missing any other critical steps.
