title: embed quiz into html5 video - cue points in a rich customizable player
body: <p>Coursera has these interactive questions in the middle of their video lecture</p>
  <ul>
  <li>how could I go about implementing this myself,</li>
  <li>or better yet, does this feature exist for public use somewhere?</li>
  </ul>
  <p><img src="https://i.stack.imgur.com/kwIZG.png" alt="custom-track-mixing" /></p>
  <p>Furthermore, I'm trying to decide which HTML5 video player / platform to invest in and the key criteria would be feature-rich (so as to not reinvent the wheel / spend lots of time implementing video player features) as well as highly customizable (for those custom needs).</p>
  <ul>
  <li>I.e. which player should I use to get the quiz up,</li>
  <li>but in the near future I would also need to add the speed feature that Coursera has</li>
  <li>I need Closed Captions support</li>
  <li>and would like to overlay slides every now and then</li>
  <li>plus all the expected features of switching between different source resolutions (360p, 720p etc), it should work in IE, Firefox, Chrome, Safari, Android and iOS native browsers etc</li>
  </ul>
  <h2>Candidates</h2>
  <ul>
  <li><p>In terms of customizability and feature-set, <a href="http://sublimevideo.net/modular-player" rel="noreferrer">SublimeVideo</a> seems to come on top, but I don't know <a href="https://getsatisfaction.com/sublimevideo/topics/_upcoming_feature_subtitles_comments_suggestions" rel="noreferrer">when they will support subtitles</a>.</p>
  </li>
  <li><p>Haven't researched <a href="http://flowplayer.org/designer/" rel="noreferrer">Flowplayer</a> much, would that be better for my purposes?</p>
  </li>
  <li><p><a href="http://www.longtailvideo.com/jw-player/features/" rel="noreferrer">Jwplayer</a> is good for all the standard features, and includes subtitle support, but I haven't really seen any plug-ins, aesthetic skinning aside, deep customization does not really seem to be their focus / strength?</p>
  </li>
  <li><p>Or <a href="http://www.videojs.com/" rel="noreferrer">videojs</a></p>
  </li>
  <li><p>Or something else yet ?</p>
  </li>
  </ul>
