I looked this over, and it seems to solve many of the issues at hand. There are no doubt some nits to iron out, but we should get agreement over the concepts before worrying too much about the details. A couple of things I wanted to comment on: You give examples of form: a=ssrc:11111 AppID:1 But you don't say too much about the meaning of this. The reason I ask is that you say elsewhere that the appid can move from one ssrc to another. My question is: If this form is used, can that appid later be bound to a different ssrc via the header extension? Also, is the following legal? a=ssrc:11111,22222 AppID:1 My other issue is with: In the CLUE WG case the mapping is from an RTP stream to a CLUE media capture specified in the CLUE framework [I-D.ietf-clue-framework]. This should be to a CLUE capture-encoding.
