Hello sir,

        I got the call stack using backtrace command in gdb. Please go
through the call stack

#0  RTSPClient::sessionURL (this=) at include/MediaSession.hh:52
#1  0x08052a93 in RTSPClient::constructSubsessionURL (this=) at
RTSPClient.cpp:1193
#2  0x0805438a in RTSPClient::sendRequest (this=) at RTSPClient.cpp:581

#12 0x0804c2e0 in RTSP_main () at playCommon.cpp:545
#13 0x0804ce0a in main (argc=<value optimized out>, argv=0xbfc9aa50) at
playCommon.cpp:972


in MediaSession.hh the the following statments get executed, I get the
"segmentation fault(core dumped)" error.

  char const* controlPath() const {
      return fControlPath; }


For a purpose, I need to call the main () again after it exits, so in main (
)  after
  env->taskScheduler().doEventLoop(&watchVariable);

I call RTSP_main(). It is just another copy of actual main ( ) .


Sir, your ideas will be helpful for me.

Regards,
Arang.
