Does it need a start code Yes, you will need to prepend 0x00 0x00 0x00 0x01 to each NAL unit before passing it to "ffmpeg" for decoding. You should also take the SDP 'configuration' string (from "MediaSubsession::fmtp_spropparametersets()"), and parse this string into a set of SPS and PPS NAL units, using the function "parseSPropParameterSets()". You should then insert these NAL units (with start codes) into your decoder (before the NAL units that come from the RTP stream). Ross Finlayson Live Networks, Inc. http://www.live555.com/
