Hi,
I have created a h.264 unicast streamer using live555 streaming library.
I have created my own H.264 video stream framer. Some issue is there with
this approach,
I have developed VideoServerMediaSubsession. In this when I am
streaming without SDP it's streaming which I can receive with VLC client.
But in another case when SDP line is there that is as follows:
char const* H264VideoServerMediaSubsession
::getAuxSDPLine(RTPSink*
rtpSink, FramedSource* inputSource) {
fDummyRTPSink = rtpSink;
fDummyRTPSink->startPlaying(*inputSource,
afterPlayingDummy, this);
checkForAuxSDPLine(this);
envir().taskScheduler().doEventLoop(&fDoneFlag);
char const* auxSDPLine =
fDummyRTPSink->auxSDPLine();
return auxSDPLine;
}
Then it is not streaming and VLC can't understand the SDP , so
the VLC player crashes. Error is coming. Here is the TCP flow of H.264
Unicast streamer without SDPLine when we return NULL.

Can someone please help me to inform me the SDP parameters for H.264 RTP
transmission over RTSP including Profile-Level-Id & sprop-parameter-set.
