3. Demo Code

~function(win, doc) {

  var Util = {}, video, snapshot, play;

  Util.get = function(selector, isList) {
    return isList ? doc.querySelectorAll(selector) : doc.querySelector(selector);
  }

  video = Util.get('#video');
  snapshot = Util.get('#snapshot');
  play = Util.get('#play');
  stop = Util.get('#stop');

  play.addEventListener('click', function(){
    Recorder.play(video, 'both', function() {
      snapshot.style.display = 'inline';
    })
  }, false);

  stop.addEventListener('click', function() {
    video.pause();
    snapshot.style.display = 'none';
  })

  snapshot.addEventListener('click', function() {
    var imgSource = Recorder.snapshot(video)
      , img = doc.createElement('img');
