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.
