Hi All, I have a question about rtcp (e.g. RR) sent from client to server in http tunnel: Gstreaming rtsp connection sends rtcp RR in base64 format, same way as rtsp request through http post channel from client to server. But I saw openRTSP is sending it in interleaved mode in post channel. (<a href="http://www.mail-archive.com/live-devel@lists.live555.com/msg03278.html">http://www.mail-archive.com/live-devel@lists.live555.com/msg03278.html</a>) I searched apple documents, unfortunately they didn't mention anything about c->s rtcp. I don't know what darwin streaming server expects from client. Any ideas which is correct base64 or interleaved (or c->s RTCP is not needed at all in reliable http connection)? Thanks. - Dake
