[Live-devel] Live input to RTSP Server

[Kumar Sambhav]

Hi,

I am trying to get live RTP data as input to the RTSP Server.

Modified H264VideoFileServerMediaSubsession::createNewStreamSource to  create a RTPSource instead of ByteStreamFileSource. 

  char const* inputAddressStr = "0.0.0.0";
  struct in_addr inputAddress;
  inputAddress.s_addr = our_inet_addr(inputAddressStr);
  Port const inputPort(50003);
  unsigned char const inputTTL = 0; // we're only reading from this mcast group
  Groupsock inputGroupsock(envir(), inputAddress, inputPort, inputTTL);
     H264VideoRTPSource *rtpSource = H264VideoRTPSource::createNew(envir(), &inputGroupsock,96,90000);
  return H264VideoStreamDiscreteFramer::createNew(envir(), rtpSource);

The program is crashing when RTPInterface::startNetworkReading calls  BasicTaskScheduler::setBackgroundHandling. From the gdb trace found that the socketNum in RTPInterface is corrupted. 
When the RTPInterface object was initialized its value was 6.  
Any idea where things might be going wrong ?

GDB Trace when the application crashed.
