body: <p>This is my code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;meta charset=utf-8 /&gt;
  &lt;title&gt;Video.js RTMP Example Embed&lt;/title&gt;
    
    &lt;link href="http://vjs.zencdn.net/4.6/video-js.css" rel="stylesheet"&gt;
    &lt;script src="http://vjs.zencdn.net/4.6/video.js"&gt;&lt;/script&gt;
    &lt;style&gt;
      div{
        float: left;
      }
    &lt;/style&gt;
  &lt;/head&gt;
  &lt;body&gt;
    &lt;div&gt;
      &lt;video id="my_video_1" class="video-js vjs-default-skin" controls autoplay width="300" height="400" 
    data-setup='{}'&gt;
      &lt;source src="rtmp://10.0.1.49/broadcast/myapp" type='rtmp/flv'&gt;
    &lt;/video&gt;
    &lt;/div&gt;
    
  &lt;/body&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I have added the autoplay attribute. But when i load the page, the videojs big button will show a moment and disappear. After that, a little circle button will appear in the middle of the video. Just like this :</p>
