As Web browser vendors line up behind Google's new open source video codec, what does that mean for the codec from Mozilla?

Six years after the project was launched, developers at the Xiph.Org Foundation have released a beta version of the free video codec called Ogg Theora. The source code of the libtheora 1.0 Beta 1 codec library can be downloaded from the developer website.

After a one year beta phase, the Xiph Foundation's free Ogg Theora video codec has been released in its final, "mainline", version 1.0.

Grant goes toward development of ARM-optimized video codec

One week after Google open sourced its $124.6m VP8 video codec, Mozilla and Opera have called for its inclusion in the still-gestating HTML5 specification. As it stands, the HTML5 spec does not specify a video codec. Browser makers are free to use any codec they like, and the big names are split between the patent-backed H.264 and the open source Ogg Theora.

Shortly before announcing its decision to remove H.264 support for HTML5 video from Chrome, Google's codec developers submitted an I-D of its VP8 Data Format and Decoding Guide to the IETF with a request for comments. The document provides a detailed description of the bitstream format and the decoding mechanism used for the VP8 video codec.

Sun Microsystems is setting out to create an open source, royalty-free video codec. Given the considerable head start of well-known, royalty-free video codecs like Dirac and Theora, you might ask why the world needs another. The answer, according to Sun, is the process the company will use to develop it -- starting with a full-on, careful examination of the patent situation.

"After several years of development, the first beta release for Ogg Theora 1.0 - a free video codec - is now available. Now all we have to do is to get some content in the Theora format."

Ever since Google announced its purchase of video codec company On2 in August 2009, there's been an expectation that On2's VP8 codec would someday be open-sourced and promoted as a new, open option for HTML5 video. An open VP8 would offer comparable quality to H.264, but without the patent and royalty encumbrances that codec suffers.
