I'm not saying that the MPEG codecs meet the 3.12.7.1 requirements. I'm
saying that ISO/IEC MPEG standards are vastly preferable to the nonstandard,
single-company junk that web developers are saddled with now. The W3C need
not abandon its ideals to declare that MPEG standards are better than the
status quo of MS, Adobe and Real "standards." From my perspective, and for
what it's worth, I doubt that the ideals of the W3C as expressed in
3.12.7.1would result in a situation that would be superior to simply
letting the
international standards body for audio and video codecs deal with these
technological areas. IF 3.12.7.1 were satisfied by Ogg or some other effort,
we would still at best end up with a bifurcated digital world, where the web
went with the free/open "standard," while every other digital representation
of video and audio was encoded in the MPEG set of standards. I just think
idealism shouldn't have to trump pragmatism in this instance.
Who wins and who loses? Web and new media developers win by having a
streamlined workflow and one expectation for video and audio standards
support in browsers. Users win by not having to worry about whether or not
they have the right plug-in for Site A or Site B. The W3C wins by having a
video tag that's reliable and complete, and not just a sort-of-better EMBED.

The issue of a small licensing fee didn't stop MPEG 1 Part 3 from becoming
the ubiquitous world standard for audio. It isn't going to stop MPEG-4 AAC
from supplanting it, and it hasn't stopped MPEG-2 and AVC from being the
standard for HD codecs. Insisting on purity in these matters while the world
moves on strikes me as just a bit quixotic.
