Hi, at the IETF last week there was consensus in the AVTEXT WG meeting to adopt the pause/resume draft [1] as a WG draft. In rtcweb/webrtc we're have the situation that we're discussing so called "doo-hickeys" as an API surface where the web app (amongst other things) can pause and resume the sending of a track. This can be signaled with the direction attribute and a SDP O/A exchange (and the app pausing/resuming sending of a track would presumably lead to a "negotiationneeded" event being fired). But I think we should in addition require the browser to signal it according to one of the methods in [1] (e.g. TMMBN = 0), and also understand that signaling (a browser receiving TMMBN = 0 must know that the other end-point will pause sending). My argument is that we know that many dislike SDP in rtcweb, and a likely development is that it will be removed in a later version. My speculation is that signaling as outlined in [1] will then be used for pause/resume. If we support this from the beginning earlier implementations could more easily interop with those later versions. Stefan [1] https://tools.ietf.org/id/draft-westerlund-avtext-rtp-stream-pause-05.txt
