Google has announced that it will be dropping support for H.264 in future versions of Chrome, and instead focus on high quality open codecs. Although Google’s announcement is surprising, it’s not completely unexpected. Last year, Google spent a fair amount of cash to acquire On2, the startup behind VP8. Later, Google unveiled its own open source codec called WebM, based on On2′s VP8. Now that WebM has begun to witness increasing amounts of hardware support, as well as improvement in performance, Google obviously feels that the time is right to put its foot down.
The core issue with H.264 has been that it is proprietary. Last year, MPEG-LA made H.264 royalty free forever for free web broadcasts, in an attempt to counter WebM. However, even that move was deemed insufficient since it didn’t include applications that encode and decode video, as well as commercial broadcasts. It also didn’t alleviate the threat that some other patent holding body might come calling.
Chrome will now join Opera and Firefox as browsers supporting only open video codecs, i.e. Theora and WebM. Microsoft had earlier announced that it will be supporting both H.264 and WebM in Internet Explorer 9, provided that the codec for the latter is installed on the system. Apple, which has been pushing for HTML5 <video> as an alternative to Flash, has been a steadfast supporter of H.264. It will probably continue to do so for the foreseeable future as hardware decoding support (which is crucial for portable devices like the iPod and the iPhone) for WebM is still fairly limited.
Although Google’s decision to drop H.264 support from Chrome represents a major setback for H.264, don’t expect it to disappear immediately. Apple’s dominance over the mobile devices segment, and the lack of WebM support in tablets and phones is something Google will have to contend with.
