Hi,
I used the Live 555 to create an RTSP client that receives video a stream of RTP over RTSP (RTP over TCP). Server is not in my control and as far as I know it was developed using Live555 as well. My client is retrieving video in very high rate (around 65-170 fps, 3-9 time faster than the capture rate) and store it for later processing. The client is implemented in VS2010 and run under Win7. I have the following strange phenomena: On a couple of PCs the client can work for hours without any problem. However on other PCs connected to the same server, on the same network, after about 1-3 minutes, for each ~3-5 frames (groups of about 4-6 packets), the RTP packets are confused to be RTSP - as if the '$' is not identified. In the beginning, I tried to understand why SocketDescriptor::tcpReadHandler1 (in RTPInterface.cpp) pass the control to the RTSP handler. However, I also captured the traffic with WireShark and saw the same confusion there! Attached please find a small capture file, if it is decoded as RTPS, the wrongfully interpretation can be seen in in packets 17-20 (server IP 10.0.0.213 client 10.0.0.111) If any other information is, larger capture file, etc.. is required – I will be happy to provide it. I will appreciate any help, hint or idea. Thanks, YocoSha
