Hi Ross,
Thanks for the correction. I fed "LiveSourceWithx264" into "H264VideoStreamDiscreteFramer" and now it works if I comment out the virtual function "getAuxSDPLine" in my implementation. In a previous question posted by user, http://lists.live555.com/pipermail/live-devel/2011-December/014276.html you said this function is needed "only for when you're streaming codecs like H.264 or MPEG-4 video that require special 'configuration' parameters" and I am streaming h264 video. My getAuxSDPLine() is char const* H264LiveServerMediaSession::getAuxSDPLine(RTPSink* rtpSink, FramedSource* inputSource) { if(fAuxSDPLine != NULL) return fAuxSDPLine; if(fDummySink == NULL) { fDummySink = rtpSink; fDummySink->startPlaying(*inputSource, afterPlayingDummy, this); checkForAuxSDPLine(this); } envir().taskScheduler().doEventLoop(&fDoneFlag); return fAuxSDPLine; } After entering into the doEventLoop() my function is going into infinite loop because it is not getting SPS and PPS nal units. If I comment out the function it is working on brower and vlc player on desktop. But it is not working on iPad brower ie it is rendering one frame and getting struck. Does this happen because I have not received SPS and PPS nal units ?

OK, your problem is that - in your implementation of the "createNewStreamSource()" virtual function - you are feeding a "LiveSourceWithx264" object into a "H264VideoStreamFramer". This is wrong, because "H264VideoStreamFramer" is used only when parsing a H.264 *byte stream*, not a discrete sequence of NAL units. Instead, you should be feeding a "LiveSourceWithx264" into a "H264VideoStreamDiscreteFramer". Also, it's important that the H.264 NAL units that you deliver - from the "LiveSourceWithx264" - into the "H264VideoStreamDiscreteFramer" *not* begin with a 0x00 0x00 0x00 0x01 'start code'. I.e., you need to remove these 4 bytes (and adjust "fFrameSize" accordingly) when you do the delivery. Ross Finlayson Live Networks, Inc. http://www.live555.com/
