Hi all,

Here's my input.

Many regards
Göran


1.	All entities MUST support H.264
a.	Are you in favor of this option [Yes/No/Acceptable]: Yes
b.	Do you have any objections to this option, if so please summarize them:

2.	All entities MUST support VP8
 .	Are you in favor of this option [Yes/No/Acceptable]: No
a.	Do you have any objections to this option, if so please summarize them:
The licensing situation is at the moment still uncertain.

3.	All entities MUST support both H.264 and VP8
 .	Are you in favor of this option [Yes/No/Acceptable]: No
a.	Do you have any objections to this option, if so please summarize them:

4.	Browsers MUST support both H.264 and VP8, other entities MUST support at least one of H.264 and VP8
 .	Are you in favor of this option [Yes/No/Acceptable]: No

5.	All entities MUST support at least one of H.264 and VP8

6.	All entities MUST support H.261

a.	Do you have any objections to this option, if so please summarize them:

7.	There is no MTI video codec
 .	Are you in favor of this option [Yes/No/Acceptable]: Acceptable
a.	Do you have any objections to this option, if so please summarize them:
    In case a consensus cannot be reached this time, a no MTI Video is acceptable for the first version 
    of the API since further discussions will continue to delay and take focus from other parts of work.
    This has the effect of also delaying the start of the work in subsequent versions, or phases, of the
    API and the underlying implementation, which is also important for the WebRTC standard competitiveness. 
    It should however be noted that long term, an MTI video is preferable.
