Google has released the latest batch of code under its WebM programme after resolving a licensing issue.
Support for the VP8 video codec for Mac, Linux and Windows has now been released to Chrome developers in the latest 6.0.422.0 build.
VP8 is supported by Mozilla and Opera, and Google is hoping that it will become the de facto open source standard for online video.
The company has also sorted out a potential licensing problem that could have caused conflict between the open source community and the WebM framework.
Chris DiBona, open source programmes manager at Google, explained in a blog post that Google had used non-standard licensing terms.
"As it was originally written, if a patent action was brought against Google, the patent licence terminated. This provision itself is not unusual in an open source software licence, and similar provisions exist in the 2nd Apache Licence and in version 3 of the General Public Licence."
"The twist was that ours terminated 'any' rights and not just rights to the patents, which made our licence GPLv3 and GPLv2 incompatible. Also, in doing this, we effectively created a potentially new open source copyright licence, something we are loath to do."
Google has now modified the terms so that companies will still lose distribution rights to WebM, but will keep the source code in accordance with existing BSD policy.
Browser and video developers are increasingly being wooed by two camps as Microsoft and Apple push H.264, and Google, Mozilla and Opera push VP8.
While Microsoft is still the dominant player in terms of browser share, Firefox and Chrome are second and third and may be able to support an alternative ecosystem.
