Hello,
If you are writing RTP packets to a file, it is handy to save the packet
data size along with, as some "axillary information," as there is no
explicit size information available otherwise. This is not related to RFC
3550.
Best regards,

Hello,
I'm looking into the process of streaming out an H.264 bitstream in RTP
packet format, as generated by the JM ref.
model, and I am using the RFC3550 and RFC3984 specs. as a reference. I have
noticed that the JM model prepends the following to each RTP packet:
   packlen [32 bits] : the RTP packet length
   intime  [32 bits] : set to the magic number 0xFFFFFFFF
I haven't been able to see any reference to the above fields in any of the
relevant specs. Does anyone know where these fields come from, whether they
are part of the RTP protocol and if they break any of the available
streaming servers out there (Darwin, VLS, ...)
thanks in advance,
