title: How can I create a thumbnail with TinyMCE's default video embed code?
body: <p>I'm using TinyMCE to embed an <code>FLV</code> video. Using the default media tool with "Flash" selected in the dropdown for "media type", this code is generated:</p>
  
  <pre><code>&lt;object width="320" height="240" 
          data="/path/to/tiny_mce/plugins/media/moxieplayer.swf"
          type="application/x-shockwave-flash"&gt;
    &lt;param name="src" value="/path/to/tiny_mce/plugins/media/moxieplayer.swf" /&gt;
    &lt;param name="flashvars" value="url=/path/to/video.flv&amp;amp;poster=/" /&gt;
    &lt;param name="allowfullscreen" value="true" /&gt;
    &lt;param name="allowscriptaccess" value="true" /&gt;
  &lt;/object&gt;
  </code></pre>
  
  <p>It looks like this after saving; white background, invisible until I hover the mouse, then the controls appear:</p>
  
  <p><img src="https://i.stack.imgur.com/Y2sh9.png" alt="enter image description here"></p>
  
  <p>The video plays fine. I've tried adding an <code>&lt;img&gt;</code> tag inside the <code>&lt;object&gt;</code>, and tried adding the path to an image in the <code>&amp;poster=</code> parameter, but it doesn't appear. I can't use YouTube. It doesn't have to be with TinyMCE, I can hand edit the HTML.</p>
