For the proposed voting process see our previous message http://www.ietf.org/mail-archive/web/rtcweb/current/msg09909.html

As I stated, we chairs will need to update this based on the discussion.

For the current list of alternatives is on the WG's wiki:
http://trac.tools.ietf.org/wg/rtcweb/trac/wiki/WikiStart


Reproduced here:
 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/
