Hello Friends, Any of you have experience in working with RTSP. I am using Live 555 open source code for implementing RTSP Client. If any of you have experience in using Live 555 open source code then please let me know how did you modify the shutdown () in playCommon.cpp. If I call the main () for the second time then I get the "Segmentation fault(core dumped)" error. I found that the shutdown () which is in the open source code is not proper. Your ideas will be helpful for me. Regards, Arang.
