Google has begun supporting a new HTML feature to show video in its Chrome browser as an alternative to Adobe's much more widely used Flash, but the technology overall remains rough around the edges.
The support comes in Chrome 3.0.182.2, a developer preview version that on Wednesday inaugurated work on the 3.0 generation of the Google browser. HTML video is one of a handful of technologies in the still unfinalised HTML 5 standard that Google hopes will transform the web from a collection of relatively static sites to a foundation for full-blown applications that rival those on PCs.
The 'video' tag in HTML already is available in various versions of Apple's Safari, Firefox and Opera, which at least in theory makes handling video on the web as easy as handling images. However, the HTML 5 standard that includes video is not finalised yet.
The video tag can be used to show video that today would show up in a conventional box, just as with Flash or Microsoft's competing Silverlight plug-in. But it also enables deeper integration with a website.
In a talk on Wednesday at the Google I/O conference, Matthew Papakipos, a Google engineering director, said HTML 5 video will permit close integration with the website's programming, so for example various actions on the website can trigger different videos to start or stop.

HTML 5 video still faces many hurdles to adoption, browser support being just the first. Next come resolution of browser compatibility problems, upgrades by browser users to support the feature, and real-world use of the technology on websites.
The challenge is illustrated by video entertainment site DailyMotion, which on Wednesday announced plans to make 300,000 videos available through the HTML 5 video technology by the third quarter of 2009. DailyMotion recommends the Firefox 3.5 beta version to watch videos, but the newest Chrome developer version and the Safari 4 beta reverted to Flash.
One issue is the technology used to encode and decode video. Firefox supports the Ogg Theora format for video (and the Ogg Vorbis format for the related HTML 5 audio tag), for example, and that is the format DailyMotion is using.
More common in the real world, however, is the H.264 standard. Papakipos said Chrome will support H.264 video and AAC audio as well as Ogg Theora video and Ogg Vorbis audio format.
