Hi Sean,

> Question #5 (hum)

> With respect to the MTI codec:
>   - Who can live with a requirement that WebRTC User Agents
>      MUST support  both VP8 and H.264 and WebRTC devices
>      MUST support  either VP8 or H.264?
>    - Who can live with a requirement that all endpoints MUST support VP8?
>    - Who can live with a requirement that all endpoints MUST support H.264?

As far as I know, we are still discussing the terminology, and meaning of "WebRTC User Agent", "WebRTC device", etc, so I don't think it is a good idea to use that in a hum at this point.

Or, if you want to use it, please provide a definition, to be used in the hum, of the terminology.

Regards,

Christer
