title: How do I turn off auto play
body: <p>I have a .mp4 video embedded in an iframe tag. I can't figure out how to turn off auto play. I tried everything: autoplay="false", autoplay="0", autoplay='false', autoplay='0' but nothing seems to work. Here's my code:</p>
  
  <pre><code>&lt;div class="embed-responsive embed-responsive-16by9"&gt;
    &lt;iframe class="embed-responsive-item behind" src='videos/cloud_computing.mp4' width='640' height='360' style='width:640px;height:360px;'&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Before this there was a YouTube video (that didn't auto play) and the code looked like this:</p>
  
  <pre><code>&lt;div class="embed-responsive embed-responsive-16by9"&gt;
    &lt;iframe class="embed-responsive-item behind" src='https://www.youtube.com/embed/v1uyQZNg2vE?enablejsapi=1&amp;amp;html5=1&amp;amp;hd=1&amp;amp;wmode=transparent&amp;amp;controls=1&amp;amp;showinfo=0;rel=0;' width='640' height='360' style='width:640px;height:360px;'&gt;&lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
