Hi, The pause and resume has the tmmbr=0 option based on RFC5104 (No IPR in the data base for RFC 5104; http://datatracker.ietf.org/ipr/search/?option=document_search&id=draft-ietf-avt-avpf-ccm) . this works well for point to point case.

Agreed. Aren't there also patent declarations against this doc from multiple holders? While SDP will likely be removed from the API in the future, the replacement would be a app-specific message sent over websockets, which seems like it would work just fine.

After all, the document was only adopted last week, and it is a rare IETF WG document that can go from a -00 WG draft to publication as an RFC in under a year.

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.
