I definitely<br>get that annex-b start codes should not be sent to the Framer, it can be<br>clearly seen in the code, but i am not sure if the framer requires the AVC<br>NAL lengths which precede the Nal data for each NAL Unit. <br></div></blockquote><div><br></div>No, you just feed the "H264VideoStreamDiscreteFramer" the NAL unit data itself. The "H264VideoStreamDiscreteFramer" doesn't need any in-band length field, because you specify the length ("fFrameSize") separately when you deliver each frame (i.e., NAL unit) to it, and the "H264VideoStreamDiscreteFramer" gets the length (as a separate parameter) whenever it receives each frame (i.e. NAL unit).</div><div><br></div><div><br></div><div><blockquote type="cite"><div>Ill try to *decipher* the RTP IETF Docs.</div></blockquote><div><br></div>You don't need to do this, because we (the "LIVE555 Streaming Media" software) have implemented these RTP payload formats for you.</div><br><br><div apple-content-edited="true">
