Re: [rtcweb] Request to postpone the question on VP8 as MTI

[Cameron Byrne <[e-mail]>]

After seeing this play out over the last few months,  i believe we
need to strongly consider no MTI for video.

It's unfortunate, but i believe the various stakeholder have
irreconcilable difference.  IPR is a dark art and the IETF has no
method for dealing with it beyond running away.  That said, run away.

Again, I need to talk to my co-chairs before we can make a decision on this but I would guess that is the direction things will need to go.

On one side the MPEG-LA announcement provides some relief but also confirms that VP8 does not come for free and that concerns were/are justified. This is further confirmed by the second announcement.

I think it is understood by now, that this would likely be more prone to success in a standardization body than anywhere else . (speaking here as a WebVC proponent that went through that process too).

It would be desirable that RTCWeb points to a standard or that VP8 reaches a certain stage in MPEG so that it can be considered as an MPEG deliverable. VP8 may reach that status at a next MPEG meeting in April or July, I don’t see how that can be accelerated further. We need to give MPEG the time to proceed properly.
