Generally speaking, Dirac is better than Theora at high resolutions.

(Additionally, while not required in any way, it's given a nod in the list of MIME type examples at http://www.w3.org/TR/html5/video.html#attr-source-type )

Not high resolutions.  High bit rates.  That's not the same thing.  And in particular, the bit rates involved are higher than bit rates one actually encounters on the web in practice, last I heard.

Yeah, s/resolutions/bit rates

5Mb/s+ isn't uncommon on the Web these days, and I've seen 4x that on an intranet with an application that would be far cooler inside a browser. What's generally considered the threshold where Dirac becomes superior?

I'm not sure... Dirac is definitely interesting but we have other priorities at the moment, and we'd want to do some legal analysis before we committed to it. A patch for Dirac support would be welcome though!

Marking WONTFIX, since we're not currently planning to implement this. We can reopen if our plans change.
