WG,

I got a comment that it was a bit confusing that just 10 and 11
contained the Constrained Baseline Profile. To my understanding all
mentionings of H.264 reference the proposal in
https://datatracker.ietf.org/doc/draft-burman-rtcweb-h264-proposal/

and all VP8 are a reference to
https://datatracker.ietf.org/doc/draft-alvestrand-rtcweb-vp8/

This has been edited into the Wiki list:
http://trac.tools.ietf.org/wg/rtcweb/trac/wiki/WikiStart

That thus read:

 The following alternatives has been proposed:

 1. All entities MUST support H.264
 2. All entities MUST support VP8
 3. All entities MUST support both H.264 and VP8
 4. Browsers MUST support both H.264 and VP8, other entities MUST
    support at least one of H.264 and VP8
 5. All entities MUST support at least one of H.264 and VP8
 6. All entities MUST support H.261
 7. There is no MTI video codec
 8. 5+6, i.e. All entities MUST support H.261 and all entities MUST
    support at least one of H.264 and VP8
 9. All entities MUST support Theora
10. All entities MUST implement at least two of {VP8, H.264, H.261}
11. All entities MUST implement at least two of {VP8, H.264, H.263}
12. All entities MUST support decoding using both H.264 and VP8, and
    MUST support encoding using at least one of H.264 or VP8

H.264 is a reference to the proposal in ​
https://datatracker.ietf.org/doc/draft-burman-rtcweb-h264-proposal/

VP8 is a reference to the proposal in ​
https://datatracker.ietf.org/doc/draft-alvestrand-rtcweb-vp8/

Cheers

Magnus
