have a parser. The parser object should parse byte after byte and
deliver complete Nals to the framer. However since my Device source is
already sending Nals using send(), I just need to do recv() to receive
a complete NAL, without needing the exhausting parsing.</font><br>

<div>This is what I would do. Note that we already do this for
MPEG-1,2 and 4 video: we have "MPEG*VideoStreamDiscreteFramer"
for sources that deliver complete frames (one at a time), and
"MPEG*VideoStreamFramer" for sources that deliver a byte
stream. So you have some existing code to use as a model.</div>
