I want to implement some protocol using RTP as the transport protocol. This protocol adapts the sending rate which is based on RTCP control information. I had read the /tcl/rtp/session-rtp.tcl, rtp.cc, rtcp.h, session-rtp.cc , and the example(simple-rtp.tcl). But I don't know how to use RTCP information. Is anybody have the simple code such like that? Thanks in advance. Yichia
