Theora Development Continues Apace, VP8 Now Open Source
SergeyKurdakov writes "Monty 'xiphmont' Montgomery of the Xiph Foundation says the latest action-packed, graph- and demo-clip-stuffed Theora project update page (demo 9) is now up for all and sundry! Catch up on what's gone into the new Theora encoder Ptalarbvorm over the last few months. It also instructs how to pronounce 'Ptalarbvorm.' Ptalarbvorm is not a finished release encoder yet, though I've personally been using it in production for a few months. Pace on improvements hasn't slowed down — the subjective psychovisual work being done by Tim Terriberry and Greg Maxwell has at least doubled-again on the improvements made by Thusnelda, and they're not anywhere near done yet. As a bonus Monty gathered all Xiph demo pages in one place."
Also on the video codec front, and also with a Xiph connection, atamido writes "Google has released On2's VP8 video codec to the world, royalty-free. It is packaging it with Vorbis audio, in a subset of the Matroska container, and calling it WebM. It's not branded as an exclusively Google project — Mozilla and Opera are also contributors. Builds of your favorite browsers with full support are available."
An anonymous reader points out this technical analysis of VP8.
Analysis can be found here. Comparison pictures to other codecs are included.
Read the blog post. Needless to say, this is astounding.
How will be the HTML5 standards organised
The HTML standard just says "play video here" just like the image tag just says "show picture here" it's up to the browser to decide how to do this, and up to the web developer to use a file format that's supported by people looking at their website.
If I have been able to see further than others, it is because I bought a pair of binoculars.
Is H264 incumbered by any patents not held by the MPEG-LA? Their argument is that if you pay to use their codec, you're in the clear patent-wise, but there's no guarantee that another 3rd party won't pull out a patent they're infringing.... and the MPEG-LA has stated they're going to start charging everybody for access to H264 anyways.
Theora and VP8 are in a better position patent-wise anyways. They both have tearms that have done searches patents (i believe VP8 has, I *know* Theora has), and they've publicly said that you're not going to get in trouble for using their stuff, EVER.

The WebM license consists of two portions: a copyright license and a patent license. The copyright license is identical to the 3-clause BSD license, which is already OSI approved.
IE9 will not support it directly. IE9 will, however, play it if the user installs support for it.
Clever signature text goes here.
Newer research is in intraframe coding and interframe prediction. VP8 uses the same methods as x264. VP8 will most likely infringe the same patents. Google does not hold these patents.
Read this take from someone who is without a doubt an expert in these matters.

That's just not true - try here and here. While W3C doesn't mandate certain formats, they give everyone specs for some. Besides, all generally useful image compression formats are freely available to anyone without any restrictions (as "freely" as it can be with any software these days).
None of the above is true with video.
Yet, there is no W3C endorsed/created video standard.
Claiming HTML5 video tag is "just like" the img tag is deceiving at best:
with images:
- W3C provides standards for some useful formats
- virtually all other generally useful formats are free/unrestricted
- all generally useful formats are supported by virtually all browsers "out of the box" (no plug-ins, no 3rd party software)
with video:
- W3C provides no standards whatsoever
- virtually all other generally useful formats are patent-encumbered*
- the only consensus between major players (minus Mozilla) so far is to support the patent-encumbered H.264 format*
* unless you think VP8 will change this landscape, which is why this is a very important announcement
