youtube chromeless as3 player

I'm goofing around with the new youtube as3 API but got stuck. This is how far i got (from looking at their sample code).

http://pastie.org/656088

public class Main extends Sprite 
{
    Security.allowDomain("*");

    private var player:Object;
    private var loader:Loader;

    public function Main():void 
    {
        if (stage) init();
        else addEventListener(Event.ADDED_TO_STAGE, init);
    }

    private function init(e:Event = null):void 
    {
        removeEventListener(Event.ADDED_TO_STAGE, init);

        loader = new Loader();
        loader.contentLoaderInfo.addEventListener(Event.INIT, onLoaderInit);
        loader.load(new URLRequest("http://www.youtube.com/apiplayer?version=3"));
    }

    private function onLoaderInit(e:Event):void
    {
        addChild(loader);
        loader.contentLoaderInfo.addEventListener("onReady", onPlayerReady);
        loader.contentLoaderInfo.addEventListener("onError", onPlayerError);
        loader.contentLoaderInfo.addEventListener("onStateChange", onPlayerStateChange);
        loader.contentLoaderInfo.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange);
    }

    private function onPlayerReady(e:Event):void
    {
        trace("Player ready: " + Object(e).Data);
    }
    private function onPlayerError(e:Event):void
    {
        trace("Player error: " + Object(e).Data);
    }
    private function onPlayerStateChange(e:Event):void
    {
        trace("Player state: " + Object(e).Data);
    }
    private function onVideoPlaybackQualityChange(e:Event):void
    {
        trace("Video quality: " + Object(e).Data);
    }
}

I don't really know what the next step is. I get no errors and nothing gets traced. I'm pretty sure that my events are not implemented correctly.

Update: I followed Amarghosh's answered and did this instead:

private function onLoaderInit(e:Event):void
{
  player = Sprite(loader.content);
  addChild(player);
  player.addEventListener("onReady", onPlayerReady);
  player.addEventListener("onError", onPlayerError);
  player.addEventListener("onStateChange", onPlayerStateChange);
  player.开发者_Python百科addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange);
}

Now the onPlayerReady and the onStateChange events fires but i get errors. When tracing Object(e).Data i get this error

ReferenceError: Error #1069: the property Data was not found for com.google.youtube.event.ExternalEvent and there is no standard value. (stranslated from swedish) When changing to Object(e.target).Data it traces "undefined" and Object(e.target) traces [object SwfProxy].

If i try player.loadVideoById("uad17d5hR5s"); i get this error:

1061: Call to a possibly undefined method loadVideoById through a reference with static type flash.display:Sprite.

sorry for all the library confusion, I think I have the answer to your other error though. When you do this Sprite(loader.content) you 'force' cast the player to be a sprite, because you want methods of the api I would recommend using a plain old object, because it won't complain about untyped methods:

// No particluar type
var player:Object;

private function onLoaderInit(e:Event):void
{
    player = loader.content;
    addChild(player as DisplayObject);

    var dispatcher:IEventDispatcher = player as IEventDispatcher;
    dispatcher.addEventListener("onReady", onPlayerReady);
    dispatcher.addEventListener("onError", onPlayerError);
    dispatcher.addEventListener("onStateChange", onPlayerStateChange);
    dispatcher.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange);
}

If the variable player is supposed to hold the loaded youtube player, change its type from Object to something more solid like Sprite.

private var player:Sprite;

Now, I don't know the youtube API, but there is a problem in your onLoaderInit method. You should be adding those listeners to the loaded content instead of its LoaderInfo object. LoaderInfo dispatches events related to the loading process - it's not relevant once the loading is successful. The events mentioned in those calls would be dispatched by the loaded content. Change the method to:

private function onLoaderInit(e:Event):void
{
  player = Sprite(loader.content);
  addChild(player);
  player.addEventListener("onReady", onPlayerReady);
  player.addEventListener("onError", onPlayerError);
  player.addEventListener("onStateChange", onPlayerStateChange);
  player.addEventListener("onPlayerQualityChange", onVideoPlaybackQualityChange);
}

relatively recently youtube released a wrapper library for their chromeless player. You should definitly use this version (you could write it again yourself, but thats reinventing the wheel), check out the tutorial/example on this page
