Multimedia, AV Monty from Xiph.org Foundation, the people behind Theora and Vorbis, have announced their support for Google's WebM container format. "The Xiph.Org Foundation is pleased to announce its support of the WebM open media project as a project launch partner. As announced earlier today at the Google I/O Developer Conference, the WebM format combines the VP8 video codec, the Matroska container, and the Vorbis audio codec developed by Xiph into a high-quality, open, unencumbered format for video delivery on the Web. Xiph will continue to contribute to WebM as a whole and collaborate in its further development and deployment." Remember, people, without the hard work from the boys and girls at Xiph, Google would not have been able to do this.

Nope. VP8 is (and has always been) designed and optimised for online video (streaming, efficiency at small resolutions, small processing and memory specs).
Theora is still the open codec of choice for offline videos, and may on the contrary suddenly improve a lot by focusing only on that, instead of trying to fit all cases. Which h264 manages to do, only because it is a very good codec (at the expense of more computational power and memory we just begin to catch up with - many new computers (notebooks) still can't natively decode h264 without buying specialized software (coreavc) or hardware (nVidia CUDA or Broadcom chipsets)) and because it has been designed from the ground up to have different "profiles" for different uses.

On the other hand, Ogg development may switch to transOgg (search for "VP8" in this webpage: https://people.xiph.org/~xiphmont/lj-pseudocut/o-response-1.html ).

Hmmmm.

transOgg quote:
That said, transOgg [the next rev of Ogg; if the Google VP8 leak is true, we'll have some breathing room soon to start more aggressively developing it] will use a lacing that pivots off of value 252 rather than 255. In this way, we still avoid 'wasting' an entire bit of numerical range when extending, but we avoid the runs of 255 to which Mr. Rullgard objects. And, it's truly the best of both worlds, which means there's no need for multiple optional encodings.


I don't know, but this quote seems to me to be saying that if Google open VP8 (as they have done, just announced), then Xiph would be interested in "back-porting" some of the optimisations in VP8 back into Ogg (Theora).

That, or they bring their expertise on VP3 to VP8 and make Theora-II, becoming what x264 is to h264.
