Let me understand it: So we are forced to use SDP in any WebRTC application but we cannot use SDP for common features (i.e. detecting that the remote peer has rejected our new offered stream/track). Thus regardless we use SDP we cannot do SIP, right? and instead we must use a proprietary signaling mechanism for those so common features already present in SIP and SDP, right? So live with SDP but don't use SDP, am I wrong? So be free to implement any custom signaling protocol (proprietary protocol) but not a standard like SIP since SIP's SDP usage cannot be implemented in WebRTC, right? Opss, I forgot, I can parse my new generated SDP at JS level (the SDP with my new video stream/track offer) and then also parse the received SDP, and detect wheter there is "a=inactive" or "m" line with port 0 to detect that the remote has rejected my stream. Am I really right? Regards. -- Iñaki Baz Castillo <ibc@aliax.net>
