I don't know how much clearer I can make this:

If you're using "H264VideoStreamDiscreteFramer", then the NAL units 
that you feed to it MUST NOT begin with the 00000001 start code.  If 
you do this, you will end up with a non-standards-compliant RTP 
packet (which receiving clients might not understand), and also our 
server code will not recognize SPS and PPS NAL units - when they 
occur.  We need to do this in order to be able to generate proper 
configuration information in the stream's SDP description.

You've already noticed that VLC does not decode your stream if you 
include the start codes.  So don't include them.
