Ran into this problem while working on a project at work. Couldn’t find this answer anywhere, so I thought I would post it.

Add the YouTube embedded player code to your page as usual, but add the highlighted parameters:

<object width=”425″ height=”344″>
<param name=”movie” value=”http://www.youtube.com/v/ZAOx_HuV3TU&hl=en
&fs=1&color1=0×006699&color2=0x54abd61″></param>
<param name=”allowFullScreen” value=”true”></param>
<param name=”allowscriptaccess” value=”always”></param>
<embed src=”http://www.youtube.com/v/ZAOx_HuV3TU&hl=en
&fs=1&color1=0×006699&color2=0x54abd6&enablejsapi=1”
type=”application/x-shockwave-flash” allowscriptaccess=”always”
allowfullscreen=”true” width=”425″ height=”344″ id=’ytvideo’></embed>
</object>

Make sure that the regular tracking code is loaded at the bottom of the page.
Add the following javascript to the top of your page:

<script>
var playedOnce = false;

function onYouTubePlayerReady(playerid) {
player = document.getElementById(‘ytvideo’);
player.addEventListener(‘onStateChange’, ‘youtubeEvent’);
}

function youtubeEvent(state) {
if (state == 1) {
if (!playedOnce) {
playedOnce = true;
pageTracker._trackEvent(‘video’, ‘unique_play_per_page’);
}
pageTracker._trackEvent(‘video’, ‘play’);
return;
}
if (state == 0) {
pageTracker._trackEvent(‘video’, ‘ended’);
return;
}
}
</script>

This will generate three types of page events:
1. ‘play’ is an event everytime the player starts playing. A play event is also when someone pauses and starts playing or scrolls to a different part of the video. This is why counting number of ‘plays’ can be misleading.
2. ‘unique_play_per_page’ counts ‘play’ events, but only one per page load.
3. ‘ended’ counts videos that have been played to the end.
