<script>
kWidget.addReadyCallback(function( playerId ){
	var kdp = document.getElementById(playerId);
	kdp.kBind('bufferProgress', function(event){
		$('.bufferEvents').prepend( "bufferProgress: " + event.newTime + " sec,  buffered: " +
				( kdp.evaluate("{video.buffer.percent}") * 100 ).toFixed(2) + "%\n" );
	})
	kdp.kBind('bufferStartEvent', function(){
		$('.bufferEvents').prepend( "bufferStartEvent\n");
	})
	kdp.kBind('bufferEndEvent', function( event ){
		// to access buffer duration you can read the event object or evaluate against mediaProxy 
		// for the latest buffer duration both in float seconds. 
		var bufferDuration = event.bufferDuration || kdp.evaluate("{video.buffer.duration}");
		$('.bufferEvents').prepend( "bufferEndEvent: bufferrTime: " + bufferDuration + " currentTime: " + 
			kdp.evaluate("{video.player.currentTime}") + "\n" );
	})
