title: Seek event for YouTube player iframe API
body: <p>Some context for the question:</p>
  
  <ol>
  <li>I know there is no event in the API to track seeking on the
  video. </li>
  <li>video.js is a very good player but there is no out of the
  box support for youtube. And I didn’t find a reliable enough plugin
  to use. </li>
  <li>I know it is possible to build custom player controls.
  This is what I plan to do. The problem is that you need to build,
  volume, play, pause, seek, speed, quality, closed caption, etc.</li>
  </ol>
  
  <p>Given that context, I need to reliable track video seeking (from position a to b) if possible using YouTube controls. Any ideas? Some insight? </p>
