As you already know , today, YouTube has started in a test mode to show videos using HTML5 tags. The developers of the Vimeo.com service have just written about the same solution.
In order to watch the movie without using Flash, on the video page you need to click on the link “Switch to HTML5 player”. While the player on HTML5 works with 75% of the video. For example, you can use it when watching a video about a coal-fired power plant located somewhere in Iowa - at the same time you will see how we pollute the environment.
As well as YouTube, Vimeo chose the H.264 standard codec, not OGG Theora, so for now only Safari, Chrome and Internet Explorer users with ChromeFrame can take advantage (how to write correctly: codec / standard / codec of H.264 standard I did not understand, despite attempts to explain this in the comments on the topic about YouTube ). ')
So far, the player on HTML5 has only one problem: the video cannot be expanded to full screen, and this is a limitation of the browsers themselves. Vimeo developers promise for the first time to add an intermediate solution: the video can be increased to the whole browser page.
