[Live-devel] The question on how to handle the incoming H.264 RTP data of live555 server

If your H.264 video source is accessible via RTSP, then you could use our new "LIVE555 Proxy Server" application, which already does all of this:

Almost.  Because the data source (a "H264VideoRTPSource") delivers discrete H.264 NAL units (i.e., one at a time), rather than a byte stream, you must use a "H264VideoStreamDiscreteFramer", not a "H264VideoStreamFramer".

Everything else looks correct, as far as I can tell.
