Your "doGetNextFrame()" function should deliver one, and only one, H.264 NAL unit (note, not a H.264 'frame') each time it's called. Note that if - at the time that "doGetNextFrame()" is called - no H.264 NAL unit is currently available, your "doGetNextFrame()" implementation should return immediately, and your "deliverFrame()" function must not get called again until later, when a new H.264 NAL unit becomes available. I suggest reviewing the "DeviceSource" demo code, and note how it uses an 'event trigger' (signaled from a separate thread) to do this.</div><div><br></div><div>Also, because you're delivering discrete H.264 NAL units (i.e., one at a time), your "OnDemandServerMediaSubclass::createNewStreamSource()" implementation should be feeding your input source object into a "H264VideoStreamDiscreteFramer", not a "H264VideoStreamFramer". (Note that, in this case, the H.264 NAL units from your input source must *not* begin with a 'start code' (0x00 0x00 0x00 0x01).)</div><div><br></div><div>Finally, because you're delivering from a live source (rather than a prerecorded source like a file), you don't need to set "fDurationInMicroseconds".</div><br><div apple-content-edited="true">
