title: How to use Open Graph to include a .swf video in a post to Facebook?
body: <p>I want there to be an attached video file (in .swf form) to a post on facebook.</p>
  
  <p>Their documentation on Open Graph is very confusing, and everything on the web seems outdated and does not work.</p>
  
  <p>Say my website is <a href="http://example.com" rel="nofollow">http://example.com</a>, and my video file is at <a href="http://example.com/player.swf" rel="nofollow">http://example.com/player.swf</a>, what meta tags do I need on my page to have the file included in the post?</p>
