[Live-devel] VLC: RTCP bug?

So It seems that "push" unicast stream is not considered in the scope of
standard IETF protocols. :-)

When you say "all parties", you mean every host which streams to the
multicast destination address?
I'm asking this because I've seen that live.com testMPEG4Streamer
actually sends/receive RTCP from/to just one UDP port, but it doesn't
seem to join the multicast group to which it sends the stream.
Besides I've read in RFC 3550 (RTP) that in some cases RTCP RR could be
turned off, such as Source Specific Multicast.

>There's no "bug" here.
I suspected that what I called a bug was instead a feature! :-)

Thanks as always.
