Many browser handle the HTML media event "waiting" differently... To me, it seems this event should fire when media has been paused to allow for buffering. This function will supply that event with a fair amount of accuracy.

custom-waiting-event.js

/* This function leverages the more cross-browser compatible event `timeupdate`
   to see if the currentTime value has changed since the media supposedly starting
   playing. The `timeupdate` event fires ~3/second, so every half second, we check
   if the currentTime has indeed changed. If it hasn't we trigger a jQuery custom event 
   
   See this issue on the video.js repo for more information regarding this bug:

function listenForWaiting(media) {
  var waiting = false;
  var playing = false;

  var checkInterval;

  var check = function() {
    return setInterval(function() {
      if(!waiting && !playing) {
        waiting = true;
        $(player).trigger('waiting');
      } else if(waiting && playing) {
        waiting = false;
        $(player).trigger('resumed');
      }
      playing = false;
    }, 500);
  };

  var stopCheck = function() {
    clearInterval(checkInterval);
    playing = false;
    return checkInterval;
  };

  media.addEventListener('timeupdate', function() {
    playing = true;
  });

  media.addEventListener('play', function() {
    checkInterval = check();
  });

  media.addEventListener('pause', function() {
    stopCheck();
  });

  media.addEventListener('seeked', function() {
    stopCheck();
    if(!player.paused) {
      checkInterval = check();
    }
  });
