In the ongoing debate over whether to employ Flash or HTML5 , Google has weighed in heavily in favour of using HTML5 . The engineers at the Google - owned YouTube , however , still prefer Flash , if a company blog itempostedTuesday from the company is any meter reading .
“ While HTML5 ’s telecasting support enables us to bring most of the content and features of YouTube to computers and other devices that do n’t support Flash Player , it does not yet encounter all of our needs , ” said YouTube software railroad engineer John Harding in the military post . “ Today , Adobe Flash provides the just political platform for YouTube ’s video dispersion demand . ”
In short , HTML5 still lack many of the features needed for picture presentation . And , as it materialise , Flash supply all these feature .
“ We postulate to do more than just aim the web browser at a video file like the image tag does — there ’s a lot more to it than just retrieving and displaying a video , ” he wrote .
Harding target out some of the HTML5 ’s shortcomings .
One of the boastful concerns was the lack of a single video format standard . “ Users upload 24 hr of video every second to YouTube , so it ’s significant to minimize the number of video formats we support , ” he said . At present tense , the company encodes upload video in H.264 , which is not endure by all Web browsers . Flash , which can run in all browsers , back H.264
YouTube also needs hunky-dory control for television playback , feature that will become increasingly significant as the inspection and repair move into extend video of live events and full - length commercial movies . One is the power to adjust buffering rates . Another feature miss is content protection . HTML5 and the browsers also lack the power to spiel back video in full screen mode , which is offer Flash ( as well as Flash challenger Silverlight , which is used by Netflix ) .
Flash also provides extra capabilities that will serve YouTube in the future , such as the power to securely embed content on another site and the ability to fend for two - way video schmoose from vane Cam .
The choice of using Flash or HTML5 for advanced Web presentation uprise into a full - scale debate earlier this year when Appledeclinedto endorse Flash in its freshly - released iPad . The company cited buggy performance and Adobe System ’s sole control over the engineering as factors .
