title: HTML5 video streaming / seeking
body: <p>I'm trying to serve videos which are being transcoded on-the-fly. Unfortunately, this means that seeking does not work. I'm assuming that this is because the browser doesn't know how long the video is and therefore can't display a seekbar properly. </p>
  
  <p>Does anyone know if it's possible to hard-code the duration of a video?</p>
  
  <p>The other option I've thought of may be to create my own seek-bar and use JS to update it's position and, if dragged, update the video URL to pass a start-time to the server.</p>
  
  <p>Any suggestions on the best way to do this?</p>
