title: video html5: Is it possible to display thumbnail from video on a specific time?
body: <p>I use this to have a video player on browser</p>
  
  <pre><code>&lt;video width="320" height="240" controls&gt;
    &lt;source src="video.mp4" type="video/mp4"&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p>Before clicking play, it display an image from the very beginning of the video, but in most of my video, first several seconds is black screen. Is it possible to make it get image at a specific time of the video, like "0:00:15", without creating thumbnail for the video?</p>
