title: Play an embedded youtube video in loop
body: <p>Does anyone know how to make an embedded youtube video to play in loop?</p>
  
  <p>I have tried the code generated from <a href="https://developers.google.com/youtube/youtube_player_demo" rel="noreferrer">official youtube developer website</a> but it does not work at all. It doesn't replay after the video ends in both Firefox and Chrome. Here is the generated code that doesn't work.</p>
  
  <pre><code>&lt;object style="height: 390px; width: 640px"&gt;
      &lt;param name="movie" value="https://www.youtube.com/v/u1zgFlCw8Aw?version=3&amp;feature=player_embedded&amp;loop=1"&gt;
      &lt;param name="allowFullScreen" value="true"&gt;
      &lt;param name="allowScriptAccess" value="always"&gt;
      &lt;embed src="https://www.youtube.com/v/u1zgFlCw8Aw?version=3&amp;feature=player_embedded&amp;loop=1" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="425" height="344"&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>I have tried to google it but there aren't any good instruction.</p>
