Please try (initially) using our “openRTSP” command-line RTSP client <http://www.live555.com/openRTSP/>, instead of VLC. If you run “openRTSP” on this combined audio+video stream, do you get two (non-zero-sized) files - one for video, one for audio - or only one non-zero-sized file (video)? > [5] > my h264 code snippet is in below > void BlockSource::doGetNextFrame() > { > if (_bFirst) > { > fFrameSize = > MyExchangeBuffer::Inst().readFirstFromVideoBlock(_strBlockName.c_str(), fTo, > fMaxSize); > _bFirst = false; > } > else > { > fFrameSize = > MyExchangeBuffer::Inst().readFromVideoBlock(_strBlockName.c_str(), > _pBlockChunkPointer, fTo, fMaxSize); > } Note that your “readFromVideoBlock()” function must *not* be blocking. I.e., if it has no video data to deliver immediately, it must return immediately, rather than waiting for data to come available. Note that I/O in LIVE555-based applications is *asynchronous* (using a single event loop - rather than multiple threads - to provide concurrency). > > > gettimeofday(&fPresentationTime, NULL);//i dont know how to set it > correctly... > fDurationInMicroseconds = 1000000 / 22;//i dont know how to dynamic set it, > so i set it to 22 fps. If you are reading from a live video source (rather than from (for example) a pre-recorded video file), you need not set “fDurationInMicroseconds”. (It will automatically get set to a default value of 0.)
