Captar o estado de um player do YouTube e retornar um "alert"

Olá pessoal, eu gostaria de saber se alguém conhece uma maneira de captar o estado

de um iframe embedded player igual ou parecido com o do player JavaScript.

Ex:

player JavaScript

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
<div id="ytapiplayer">

You need Flash player 8+ and JavaScript enabled to view this video.

</div>

<script type="text/javascript">
var params = { allowScriptAccess: "always" };
 var atts = { id: "myytplayer" };
 swfobject.embedSWF("http://www.youtube.com/watch?v=M7lc1UVf-VE?enablejsapi=1&playerapiid=ytplayer",
 "ytapiplayer", "425", "356", "8", null, null, params, atts);

function onYouTubePlayerReady(playerId) {
ytplayer = document.getElementById("myytplayer");
 ytplayer.addEventListener("onStateChange", "onytplayerStateChange");
}

function onytplayerStateChange(newState) {
 alert("Player's new state: " + newState);
}
 </script>

Seria possível extrair um alerta do iframe embedded player?

<iframe id="ytplayer" type="text/html" width="640" height="360"
src="https://www.youtube.com/embed/M7lc1UVf-VE?autoplay=1&fs=1"
frameborder="0" allowfullscreen>
Agradeço a atenção!
