Hi Hubert; Actually my implementation is quite different from yours. I want pjsip to stream h264 from one side to other.. You choose VLC to do it.. I changed pjmedia_session_create and pjmedia_stream_create functions as well as SDP negotiation. I want vlc to decode this h264 stream with file.sdp which includes remote ip and port information with codec. Did you install Microsoft Platform SDK for direct show headers ?
