[Live-devel] RTCP Receiver Reports use

Do 'we' not have our own domain name? :-)

You realize, I hope, that 2004 was 8 years ago :-)  We've had full support for RTCP "RR" and "SR" packets for many years now.

You may be confused by the difference between RTCP "SR" (Sender Report) packets and RTCP "RR" (Reception Report) packets.  We implement (the sending and receiving) of both kinds of RTCP packet.  Note, however, that a RTP server (transmitter) sends RTCP "SR" packets (and receives RTCP "RR" packets from receiver(s)).  A RTP client (receiver) sends RTCP "RR" packets (and receives RTCP "SR" packets from the server).

But anyway, the important thing to note is that these packets get sent and received automatically (by the "RTCPInstance" objects).  You don't need to do anything special to implement them.

"testMP3Streamer" sends RTCP "SR" packets, and will receive RTCP "RR" reports from any (multicast-connected receivers).  "testMP3Receiver" sends RTCP "RR" packets, and will receiver RTCP "SR" packets from "testMP3Streamer" (provided, of course, that multicast routing is enabled between the computers that run "testMP3Streamer" and "testMP3Receiver").
