It appears that we're running headlong into another in-person discussion
about the relative merits of H.264 and VP8 as MTI candidates again.
Matthew Kaufman has argued that this conversation is doomed to failure
because no major player has been willing to change their position. The
players he cited were Cisco, Google, and Mozilla, who have represented
the three main positions on this topic pretty effectively. Although we
participate as individuals in the IETF, I think it's fair to say that
the last time we had this conversation, the median positions of
participants from those companies were "H.264 or die", "VP8 or die", and
"either one as long as it's *only* one", respectively.
However, even if nothing else has changed, I think one salient point may
have become quite important: we're all tired of this. Over two years
ago, in March of 2012 -- before I even had an particular interest in
WebRTC except as a user -- this had already become such a long-running
acrimonious debate that I was brought in as a neutral third party to try
to mediate. I'm weary of this argument; and, with the exception of a few
aggressive voices who seem to enjoy the battle more than the outcome,
I'm hearing a similar exhausted timbre in the messages of other
participants (and the key stakeholders in particular).
So, I want to float a proposal that represents a compromise, to see if
we can finally close this issue. First, I want to start out by
reiterating a well-worn observation that the hallmark of a good
compromise is that nobody leaves happy, but everyone can force
themselves to accept it. And I want to be crystal clear: the solution
I'm about to float just barely clears the bar of what I think I can live
with. This proposal is based on an observation that the dominating
issues in this conversation remain those of licensing, not technology or
even incumbency. I’ve discussed this extensively with representatives of
all three of the players I mention above, and they are willing to sign on.
This proposal is based on the definitions of "WebRTC User Agent",
"WebRTC device", and "WebRTC-compatible endpoint" in section 2.2 of
draft-ietf-rtcweb-overview-12.txt. My proposal would be as follows:
1. WebRTC User Agents MUST implement both VP8 and H.264.
2. WebRTC devices MUST implement both VP8 and H.264. If compelling
evidence arises that one of the codecs is available for use on a
royalty-free basis, such as all IPR declarations known for the codec
being of (IETF) Royalty-Free or (ISO) type 1, the IETF will change
this normative statement to indicate that only that codec is
required. For absolute, crystal clarity, this provision is only
applicable to WebRTC devices, and not to WebRTC User Agents.
3. WebRTC-compatible endpoints are free to implement any video codecs
they see fit, if any (this follows logically from the definition of
"WebRTC-compatible endpoint," and doesn't really need to be stated,
but I want this proposal to be as explicit as possible).
This has the property of ensuring that all devices and user agents can
work with all devices and user agents. This has the property of giving
no one exactly what they want. And, unlike any other previous plans,
this has the property of coming to a decision while maintaining pressure
on the only parties who can make a change in the IPR landscape to do so.
