YouTube Javascript API sample with selenium

Play embedded youtube video with selenium via JS API.
1. Sample HTML page:

<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>

<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);


// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '480',
width: '853',
videoId: 'u1zgFlCw8Aw',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}

// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
<!--alert("player ready"); event.target.playVideo(); -->
}

// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
<!-- setTimeout(stopVideo, 6000); -->
done = true;
}
}
function stopVideo() {
player.stopVideo();
}

function startVideo() {
player.playVideo();
}
</script>
<div>VIDEO Test</div>
<a href="javascript: void(0)" class="stop" onclick="player.playVideo(); return false">Play</a> <a href="javascript: void(0)" class="stop" onclick="player.stopVideo(); return false">Stop</a>
</body>
</html>

2. Start video via URL click:
/*
* URL click
*/
WebElement q = driver.findElement(By.className("play"));
 q.click();

3. Start video via JS invoke:
/*
* JS invoke
*/
JavascriptExecutor js = (JavascriptExecutor) driver;
  js.executeScript("javascript:player.playVideo();");

Troubles with IE. Expected :)
