This plugin is designed to operate on media files hosted outside your WordPress site. It does not integrate with the Media library, and it does not create the media files.
This plugin is used to show videos on wordpress blog. You need to enter simple shortcode on your page and the plugin generates the HTML to deliver the media. Browsers that understand the HTML5 tag will use Ogg/Theora .ogv files and secondarily MPEG/H.264 .mp4 files. Other browsers can play the .mp4 with a QuickTime plugin. If they have it, still other browsers can use Flash to play the .mp4.
In all cases, the markup includes links to download the media files. The HTML used here diverges only slightly from the Video for Everybody model. See that site for fuller details.
Requires WordPress Version: 2.8 or higher
