Re: [whatwg] Suitable video codec

yea.. the take home point is that Theora now has an encoder that puts it 
in the same ballpark as contemporary proprietary codecs. I would not say 
Theora is outdoing h.264. The results of a given PSNR test are 
impressive and important to publicize but I think my wording in posting 
about that test might have promoted overstating the quality factor.


The only quality that really mattered in terms of standardization has 
stayed constant: which is Ogg Theora is /royalty free/ and implementable 
in both proprietary and free software browsers.

The Thusnelda coder is outdoing H.,264 in current tests:

This is of course developmental work. I'm sure the advocates of H. 264
can also tune its encoders to keep up, and not make Theora the only
reasonable candidate for the video element.

Be careful how glowing you make this sound -- this is on a particular
objective test (not subjective, and thus perversely less accurate in
reflecting how good do people think this looks), and only based on one
video clip.

That's not to diminish the Theora work at all -- the results are also
subjectively better IMO, and Theora getting better is a win no matter what.
