Hi,everyone!<br>       I was asked to write a multiview media streaming client that can playing multiple rtsp video stream concurrency. I encapsulated the openRTSP into a C++ class that has it's own environment/taskscheduler /RTSPClient and eventloop. While try to connect to the latest live555 media server(testOnDemandRTSPServer.cpp),it works fine. But while access an IP Camera that developed based on the live555 media server 2008.04.02 version,the following thread all received the duplicate data with the first thread (as shown in the following log,all thread/instance received the same data size,which was different while access to the latest live 555 media server  ). And I also find that two Videolan process can access the IPC concurrency and play the video fine. Can you please give me some information/suggestion how to debug this issue? Which part of the code may cause this problem? Thanks very much! <br>
