The WebM Community Cross-License (CCL) initiative enables the web community to further support the WebM Project. Google, Matroska and the Xiph.Org Foundation make the various components of WebM openly available on royalty-free terms. By joining the CCL, member organizations likewise agree to license patents they may have that are essential to WebM technologies to other members of the CCL.

A couple of weeks ago Google announced their WebM project, which provided a free software implementation of their VP8 video codec and a license to exercise the patents the company held on the software.

Despite their claims that WebM was been checked for patent risks when ON2 was acquired, Google has neither made its research available nor does it offer a patent indemnity. Google has expressed extreme confidence in the patent safety of WebM, yet has failed to create a patent pool with its other endorsers and grant free and indemnified licenses to WebM contributors.

Google’s WebM, an open and royalty-free media format based on the VP8 video codec, was amongst the highlights coming out of Google I/O 2010. After examining the software license, open source pundits questioned whether WebM should, in theory, be classified open source software.

Google is adopting the BSD license for WebM in order to address a licensing conflict. When Google opened up the VP8 codec and announced the launch of the WebM project during the Google I/O conference last month, the actual license under which the code was distributed was not an official open source software license.

On May 19, Google unveiled something that many in the open source community had been expecting (and which the Free Software Foundation asked for in March): it made the VP8 video codec available to the public under a royalty-free, open source BSD-style license.

From today, users will be able to download and install free software to play and encode the new WebM format. WebM is based on the Matroska container format -- replacing Ogg -- and the VP8 video codec which replaces Theora. Crucially, the Vorbis audio codec is part of the new WebM specification.

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 the Xiph into a high-quality, open, unencumbered format for video delivery on the Web.

The FFmpeg project has released version 0.6 of FFmpeg, improving HTML5 video and adding support for the latest open WebM / VP8 video format introduced by Google as part of the WebM Project
