Re: [rtcweb] Plan for MTI video codec?

I am hearing a lot of folks outside this group losing faith and beginning to talk about writing off WebRTC for lack of consensus (including analysts).

I am therefore in favor of a very finite amount of "new-news" discussion and another attempt at consensus. We either do or don't have it.

The working group has repeatedly said that an MTI codec is something we need to produce. And its one of the issues holding up wider adoption of the technology (not the only one for sure).

And things have changed since the last meeting, a year ago now (November in Vancouver). Cisco's open264 plugin shipped and now just recently is integrated into Firefox. iOS8 shipped with APIs for H264. There are other things worth noting. Will this change the minds of everyone? Surely not. Will it sway enough for us to achieve rough consensus? Maybe. IMHO - worth finding out.

+1 to not having MTI codec discussion unless some progress has been made on VP8 at MPEG. Any news on that? I'm sharing harald's  feeling that there was no change on the members position.

One thing we could do instead of wasting time on MTI is to actually make progress on Sections 4.2 - 4.4 of draft-IETF-RTCWEB-video, so we could actually interoperate regardless of the codec.

The big argument for an MTI is actually the one stated in -overview: It guards against interoperability failure.

I would like to have an ecosystem where one can field a box, connect it to everything else, and run well for *some* level of "well" - and I would prefer that ecosystem to be one where it's possible to field the box without making prior arrangements with anyone about licenses.

This argument hasn't changed one whit since last time we discussed it. And I don't see much movement on the specifics of the proposals either.

We'll have to interoperate well with the codecs we field. So using some time to discuss draft-ietf-rtcweb-video seems to make sense. (And 4.1 isn't finished either. There's one sentence that needs to be removed.)

I wouldn't say I'd be happy to not discuss this in Honolulu. But I'd prefer to re-discuss based on the knowledge that some significant players have actually changed their minds.

At the moment, I don't see signs that any of the poll respondents have said "I have changed my mind".

And that's because something substantive has changed, or simply because
wasting the WG time on this again is more entertaining than actually
finishing a specification that can be independently implemented by all
browser vendors? (A specification that we are nowhere near having, as far as
I can tell)
Personally, I've found the reprieve from this fight refreshing.  And
it would appear that we've made some real progress as a result.  I'd
suggest that if we don't have new information, we continue to spend
our time productively.  If we can't find topics to occupy our meeting
agenda time, then maybe we can free an agenda slot.
