Then, in case you've missed any of these: You asked how Plan A endpoints would work with No Plan browsers here: http://www.ietf.org/mail-archive/web/rtcweb/current/msg07696.html The reply, with sample SDP went here: http://www.ietf.org/mail-archive/web/rtcweb/current/msg07724.html You then moved the thread to MMUSIC and asked to see the answer here: http://www.ietf.org/mail-archive/web/mmusic/current/msg11347.html In the above you also asked how the answerer could refuse one video stream. I replied with the SDP answer and additional sample signalling here: http://www.ietf.org/mail-archive/web/mmusic/current/msg11354.html I don't think I've seen any additional questions from you since then.You are now saying that the situation is still unclear, so please let me know if I can help in any way. Otherwise we could also switch to whatever problems you have with the approach itself. In the mean time, again on MMUSIC, Eric has asked for more detailed examples including sample JS code here: http://www.ietf.org/mail-archive/web/mmusic/current/msg11360.html Enrico has put up a very helpful and very complete example to this here: http://www.ietf.org/mail-archive/web/mmusic/current/msg11382.html I added a nit here: http://www.ietf.org/mail-archive/web/mmusic/current/msg11386.html Cheers, Emil -- https://jitsi.org
