[whatwg] several messages regarding Ogg in HTML5

I've tried to pick a representative sample of the e-mails sent since my
last e-mail. The ones I didn't reply to have been saved to the outstanding
video codec feedback folder, and I'll reply to them once we have a real
solution to the problem of finding a common codec.
(The list is updated daily, so it doesn't yet have all the new e-mail.)
I would encourage new participants to read this blog entry from Chris
Double, the Mozilla engineer who implemented most of <video> in Firefox,
as it summarises the issues nicely:

There are several solutions we might find. For example:
* We could convince the MPEG-LA group to provide a royalty free license
for one of their codecs, e.g. H.264 Baseline.
* We could wait for Ogg to be used by a large fraction of the Web
population, as that would provide the business reason for companies
like Apple to support Ogg.
* We could use an codec old enough that all patents claimed to
be essential to its implementation have expired.
The discussions to these ends are happening.

It's a matter of risk management. Some things are worth the risk, others
might not be. Video codecs tend to be _extremely_ risky.

To be honest at the end of the day it doesn't actually matter _why_ Apple
and Nokia won't implement Ogg Theora. If they don't implement it, we don't
have interoperability, and we've failed in our goal.

Actually, right now _nobody_ is getting their way. The spec doesn't say
_what_ codec should be used. Requiring Ogg Theora support would be not
taking everyone's needs into account. Right now, the spec just lists
everyone's needs, without a solution.

Indeed, H.264 is unacceptable as well.

Not for companies that have already taken the risk of one of the codecs
already. For example, if Opera ships with Ogg Theora, then they'd probably
be less interested in also supporting Dirac (another theoretically "free"
video codec), since doing so would increase their potential patent "attack
surface". (Also, the smaller the company, the less the risk. Companies
like Microsoft, Apple, and Google take on huge risks. Just look at
Microsoft's track record recently getting sued for patent infringements,
or Apple's track record of being sued over patents that the iPhone

There's no point putting a MUST in the spec if we _know_ that it won't be
followed. We're not writing specs to satisfy a theoretical need, we're
trying to get actual interoperability across all browsers.

We have been told that Theora is not something everyone can implement.
Whether you agree with the reasoning or not doesn't actually matter at the
end of the day, it's still something that can't (or won't) be implemented

I'm sorry you believe that. It really isn't supposed to be. We're trying
to find a solution that works for everyone.

Making it a MUST doesn't make it possible for everyone to implement. If
only standards development worked that way! It would be far easier.

We have to take into accounts the needs of everyone. This includes large
companies. If large companies will only accept codecs that they've already
implemented, then that may have to be one of the criteria.

Actually, all browsers are in scope to the WHATWG work. It would be short
sighted in the extreme, for instance, to ignore IE, since they have a
controlling position in the market.

I hope we can find a solution that doesn't involve giving up. :-)

If you don't believe the reason they have given, that's your right. But it
doesn't actually matter what the reason is (except for finding a solution
that does address their needs), as noted above.
(For what it's worth, I have very good reasons to believe that their
stated reasons are in fact true. But I can't convince you of that and I
won't embarass us by trying.)

Whatever solution we find will be one that is royalty free and open. That
is not in any doubt.

As the person who would make that decision, I assure you that no decision
has in fact been made. That is, in fact, the entire crux of the issue.
> If things are up in the air, then why change it?
Because the SHOULD-level requirement on Ogg did not represent the actual
status of the spec and of the current consensus. The spec should reflect
reality -- that, if anything, is an underpinning principle of the WHATWG.

If the text moves to requiring a non-free codec, then you will have been
screwed, and then you should raise almightly hell. However, no such
decision has been made (and no such decision will ever be made, at least
not while I'm involved).

No, the change here is from a free codec that not everyone will implement
to an open issue that describes what we need, which is, amongst other
things, a free codec.
