Thanks for the answer, it is working now ! To be able to send a stream with VLC, I would have a few question about callbacks (always following simpleua.c model) : - on-rx-request : I would just remove *pjmedia_endpt_create_sdp* to create manually a sdp session to be used by *pjsip_inv_answer*, am I right ? - call_on_media_update : this should be where I use VLC to send my stream. Which function is calling this callback ?
