		My problem is the following:
		

		ByteStreamFileSource needs that H264VideoStreamFramer to
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.
		

		What is the right thing to do (to keep only one Framer)

	[...]


		3. implementing two types of framer. One that make use
of the parser, and one that doesn't. (what I tried to avois)


	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.
