Hi, I wanted to create an application similar to streamutil sample in my application but which can send/receive rtp to/from a multicast ip. i have seen an example in http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-July/003974.html but i dont understand whether the RTP/RTCP sockets are added into a multicast group. What i want to do here is receive RTP packet from a Cisco router which sends/receives RTP packets on to a multicast group. Can someone please clarify what exactly is needed to accomplish my task.
