<div><span></span>hi Ross,</div><div><br></div><div>I followed your suggestion to use <span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">“H264VideoStreamDiscreteFramer” instead of </span><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;">“H264VideoStreamFramer”. Now that the data seems to be consumed right away after "afterGetting" callback, but VLC player can't set up session. </span></div><div><span style="font-size: 10.5pt; line-height: 1.5; background-color: window;"><br></span></div><div>For the start code, I have eleminated them all. My camera's working pattern is like this, when encoding key frame, it outputs SC+SPS+SC+PPS+SC+Frame, when encoding non-key frame, it outputs SC+Frame. So, after I eleminated the SC, what I sent to the sink object is SPS+PPS+FRAME for key frame, and FRAME alone for non-key frame.</div>

<div> </div>
<div>Look at your implementation of the “createNewStreamSource()” virtual function (in your “OnDemandServerMediaSubsession” subclass). Because your data source - from your encoder - is discrete H.264 NAL units (i.e., one at a time), rather than a byte stream, you must use feed your input source to a “H264VideoStreamDiscreteFramer”, *not* a “H264VideoStreamFramer”.</div>
<div> </div>
<div>Note also that each ‘frame’ that come from your input source must be a single H.264 NAL unit, and MUST NOT be prepended by a 0x00 0x00 0x00 0x01 ‘start code’.</div>
