title: How to embed a iframe player in FB's wall?
body: <p>I been trying to embed a iframe player on FB with OG tags unsuccessfully.  But I found that <a href="http://player.kaltura.com/docs/Share" rel="nofollow noreferrer">Kaltura</a> player cans. I'been trying to copy what they did, but couldn't make it work. </p>
  
  <p><a href="http://player.kaltura.com/docs/Share" rel="nofollow noreferrer">Here</a> and <a href="https://blog.kaltura.org/facebook-now-require-html5-and-fallback-in-open-graph" rel="nofollow noreferrer">here</a> Kaltura explains how to embed their player in FB. Basically they say that you should put the following tags:</p>
  
  <pre><code> &lt;!-- Facebook iframe embed  --&gt;
   &lt;meta property="og:video:url" content="https://cdnapisec.kaltura.com/p/243342/sp/24334200/embedIframeJs/uiconf_id/28685261/partner_id/243342?iframeembed=true&amp;playerId=kaltura_player&amp;entry_id=1_sf5ovm7u"&gt;
   &lt;meta property="og:video:secure_url" content="https://cdnapisec.kaltura.com/p/243342/sp/24334200/embedIframeJs/uiconf_id/28685261/partner_id/243342?iframeembed=true&amp;playerId=kaltura_player&amp;entry_id=1_sf5ovm7u&amp;"&gt;
   &lt;meta property="og:video:type" content="text/html"&gt;
   &lt;meta property="og:video:width" content="560"&gt;
   &lt;meta property="og:video:height" content="395"&gt;
  </code></pre>
  
  <p>Of course I tried that and many other things, like coping Kaltura Http headers. But it did not work, any clue why it works for them? What I'm missing?</p>
  
  <p><strong>Note:</strong> This is a duplicated <a href="https://stackoverflow.com/questions/28776610/how-to-embed-custom-html5-player-on-facebook-post">question</a>, but I wanted to add this Kaltura exception that I found.</p>
