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.

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.

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.

Why the next version of your Web browser, media player or GNU/Linux distribution will probably contain VP8/WebM code; Apple and MPEG-LA continue to be the main barriers to VP8/WebM adoption

...along comes Google. And instead of piling on to this patent suit scrum, they offer immunity instead. Which is astonishing.

Software patents FUD withstanding, the status of WebM as a Free/open source project is being actively addressed

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.
