If you want to attach a video to your Open Graph page you can simply specify a video url. Facebook uses the og:video:type to determine how to render the video in the news feed. In desktop browsers and Flash-enabled mobile browsers, Facebook will render "http://example.com/awesome.swf" as a Flash video. In Safari on the iPad, Facebook will render "http://example.com/html5.mp4" inside an HTML 5 <video> tag. In browsers which support neither Flash nor HTML 5, Facebook will link to "http://example.com/fallback.vid" when the video thumbnail is clicked.
