Administrator DKT27 Posted April 21, 2011 Administrator Share Posted April 21, 2011 YouTube has announced that it is now transcoding all newly uploaded videos into WebM format. In addition, the entire back catalogue is in the process of being transcoded to WebM; the focus has been on the most popular videos, and those that account for 99 per cent of views are now in WebM, although these only account for 30 per cent of the total back catalogue. The YouTube announcement states that the reason for adopting the open format for video is to "deliver great content to you wherever you are". YouTube is also part of Google and switching YouTube to WebM would be a major step forward for Google's open sourced video format. As YouTube will continue to also support the H.264 format, this means that the company's videos will be playable with the HTML5 <video> tag in most of the latest browsers. Internet Explorer and Safari support H.264 only for the <video> tag, Firefox and Opera only support WebM and currently Google's Chrome supports either format though Google has announced it will remove the H.264 support at some point. Users wishing to try out the WebM format in YouTube should attach &webm=1 to the search string or to the URL of a known video .

toyo Posted April 21, 2011 Share Posted April 21, 2011 Yeah. Useless for now, no hardware acceleration, so HD play is eating your CPU like crazy. I was back to Flash in a minute. You must "join" the HTML5 trial here, first: http://www.youtube.com/html5 Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted April 21, 2011 Author Administrator Share Posted April 21, 2011 Only Opera doesn't have Hardware Acceleration ATM right? O.T. When will it introduce? :) Well I would have tested it but my internet is going nuts from last 15 days, specifically at these hours. :frusty: Link to comment Share on other sites More sharing options...
toyo Posted April 21, 2011 Share Posted April 21, 2011 Some testing on Win7x64:- Opera: flash is accelerated (for H264 at least, works with a minimum of CPU - 10% of a 3 GHz dual core at 1080p); WebM - no acceleration, 50% CPU or more at 720p- Chrome: flash: accelerated, like in Opera; WebM no acceleration at all, eats CPU like crazy- IE9: flash: same as Opera; WebM: some acceleration, GPU goes into UVD state (500 MHz GPU / 750 MHz video RAM), CPU load: 17-20%- FF: flash is again accelerated as in Opera; WebM: the pathetic hardware acceleration FF has springs into action at full 625/993 3D speeds on the videocard, but even at full GPU speed, the CPU is still loaded up to 40%.I'm not sure what FF tried with it's current implementation of hardware acceleration, but it's ages behind IE 9, however it's better than Opera, that doesn't have any, and I dunno when they plan adding it :( Link to comment Share on other sites More sharing options...
