Hi all I am having some weird problems at the moment. I am running a server and a laptop with the exact same kernel and software (obviously different hardware), and having some strange problems with that.
On my laptop, starting the testOnDemandRTSPServer takes no time at all. On my server, the application uses a few seconds to start. Running valgrind and killing the process while in this "waiting state" at the beginning tells me: ==26912== Process terminating with default action of signal 2 (SIGINT) ==26912== at 0x568D053: select (in /lib/libc-2.6.1.so) ==26912== by 0x448116: readSocket(UsageEnvironment&, int, unsigned char*, unsigned, sockaddr_in&, timeval*) (in /home/mt/live/testProgs/testOnDemandRTSPServer) ==26912== by 0x44868B: ourSourceAddressForMulticast(UsageEnvironment&) (in /home/mt/live/testProgs/testOnDemandRTSPServer) ==26912== by 0x428EC0: RTSPServer::rtspURLPrefix(int) const (in /home/mt/live/testProgs/testOnDemandRTSPServer) ==26912== by 0x428EEC: RTSPServer::rtspURL(ServerMediaSession const*, int) const (in /home/mt/live/testProgs/testOnDemandRTSPServer) ==26912== by 0x40223A: announceStream(RTSPServer*, ServerMediaSession*, char const*, char const*) (in /home/mt/live/testProgs/testOnDemandRTSPServer) ==26912== by 0x4023AE: main (in /home/mt/live/testProgs/testOnDemandRTSPServer) Since "readSocket(UsageEnvironment" only exists in GroupsockHelper.cpp and GroupsockHelper.hh, and there is only one select in the entire file, I am pretty sure the delay happens at line 229 in GroupsockHelper.cpp. The server seems to also output a different IP address than the laptop as well, laptop using eth0, while the server uses... eh, some other address: "mpeg4ESVideoTest" stream, from the file "test.m4e" Play this stream using the URL "rtsp://127.0.1.1:8554/mpeg4ESVideoTest" It seems from the trace that the ourSourceAddressForMulticast is the sinner. Firstly, what does multicast have to do with the RTSP server? Is that not purely unicast? Secondly, how can I remove this delay? It is not critical, but quite annoying, especially the fact that my lousy laptop "performs better" from the client point of view =) As mentioned, running the exact same kernel, so multicast support should be the same in both. They are the latest realtime kernels from Ubuntu. Thanks for any help with this. -Morgan Torvolt- _______________________________________________ live-devel mailing list [email protected] http://lists.live555.com/mailman/listinfo/live-devel
