title: Draw shapes on HTML5 Canvas...with video
body: <p>I've been Googling around a bit for an answer and haven't found a definitive one either way: <strong>is it possible to play a video using an HTML5 canvas, and also allow the user to draw on this video?</strong> The use case, for some context, is to play a video on infinite loop so the user can draw multiple boxes over specific areas to indicate regions of interest.</p>
  
  <p>As a bonus (:P), if I can figure out how to do this on its own, any hints as to how this could be done within Drupal? I'm already looking at the Canvas Field module, but if you have any hints on this point too (though the first one is the priority), that'd be awesome!</p>
