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

[Gaelle Martin-Cocher <[e-mail]>]

Dear All,

I am following up on my request to postpone the discussion.
It appears that the new license for VP8 and the Nokia declaration in IETF on VP8 are not available yet.
Questions were not answered either.
The meeting has started, and that particular discussion is planned for Thursday.

In light of the recent email exchanges, it is clear that the discussion is not technical at all anymore; this is about risk assessments and legal matters. 
It seems that it would be necessary that legal counsels from IETF and from the various companies are involved in the discussion. I am not sure if this topic will be better dealt with in the RTCWeb group of if there is another group in IETF that would be more suitable. 
One (as a technical expert) can try to bring his/her legal counsel up to speed quickly; but within that time frame and without tangible information that is very improbable  that our respective legal counsel will be able to have an informed position and that each one of us would be in a position to reach a consensus on Thursday.

I am hence re-iterating my request to postpone that discussion. Cullen (or chairs) , would you mind giving an update on this?

Sincerely,
Gaëlle

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.

I also think it would be prudent to defer the codec decision.

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.

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.
