<DIV>Hi ALL.<BR> I developed a program modeled "testOnDemandRTSPServer" capture screen in real time, and then compressed into h264 and released. In the beginning the test, the client uses UDP to transmit data, the server is working properly. Then I want to test TCP mode, let the client choose RTSP over tcp, server performance is not normal, probably sent a few minutes after stop sending packets (using Wireshark capture). In debug mode, the server is still report "sending report, sending packetˇˇ". Until 65 seconds (default timeout) after the service side display "time out".<BR> Then I tried a variety of approaches to debug, still does not solve the problem. So to see the "live555MediaServer" source code and use it as a server test, the results "live555MediaServer" also have this problem, and greater the resolution of the video, there is a problem of time sooner.</DIV>
<DIV> </DIV>
<DIV>Remarks:<BR> 1. the server (live555 libraries and MediaServer): Version Dec 09 2014<BR> 2. the client has three: testRTSPClient, VLC (2.1.5), FFMpeg (N-67100, oct 22 2014).<BR> 3. if the server has consol window and enable DEBUG_SEND, then the server is working properly.</DIV>
