title: autoplay=1 not working for <iframe> in playing video in mobile devices
body: <p>I'm working with video. When i click on Video Thumbnail a pop appears and Video plays in that,I need to start play the video (without clicking the play button) when popup opened.I tried with code below.</p>
  
  <p>It was working perfect in web but not in mobile devices like iPhone ,iPad</p>
  
  <pre><code>&lt;iframe
          title="YouTube video player"
          id="videoFrame"
          class="youtube_iframe" src="http://www.youtube.com/embed/JW5meKfy3fY?wmode=opaque&amp;amp;autoplay=1"
          frameborder="0"   width="395" height="280"        allowfullscreen=""        scrolling="no"&gt;
  &lt;/iframe&gt;
  </code></pre>
