[Live-devel] Capturing H.264 content with openRTSP

Yes, that would work.  (Note how we already do something similar for 
incoming AMR audio frames; search for "AMRAudioFileSink" in 
"playCommon.cpp".

No, your "DeviceSource" is correct by not including the "0 0 0 1" 
prefix.  That is not supposed to be part of the NAL unit data that 
gets sent in outgoing RTP packets.

Update the implementation of "QuickTimeFileSink" to support H.264 
content :-)  (If you want to try doing this, look for "h263" and 
"mp4v" for examples of how it already supports H.263 and (regular) 
MPEG-4 video.)
