Develop with the Official YouTube Chromeless Player AS3 API
October 25th, 2009 in Flash | 15 CommentsA few days ago, Google released the official YouTube Chromeless Player AS3 API that gives us an exciting perspective of building flash applications integrating seamless Youtube videos.
Check out their announcement and the YouTube ActionScript 3.0 Player API Reference
Now let’s see a simple example that integrates a YouTube video into an ActionScript 3 Flash application with this API.
1. Create a new flash file (actionscript 3) and save it as youtube.fla. Set the stage size to 640×360 pixels.
Rename “layer 1 ” to “actions” and open the actions panel.
2. Following the YouTube ActionScript 3.0 Player API Reference, copy and paste the following code:
import flash.system.Security;
Security.allowInsecureDomain("*");
Security.allowDomain("*");
// This will hold the API player instance once it is initialized.
var player:Object;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.INIT, onLoaderInit);
loader.load(new URLRequest("http://www.youtube.com/apiplayer?version=3"));
function onLoaderInit(event:Event):void {
addChild(loader);
loader.content.addEventListener("onReady", onPlayerReady);
loader.content.addEventListener("onError", onPlayerError);
loader.content.addEventListener("onStateChange", onPlayerStateChange);
loader.content.addEventListener("onPlaybackQualityChange", onVideoPlaybackQualityChange);
}
function onPlayerReady(event:Event):void {
// Event.data contains the event parameter, which is the Player API ID
trace("player ready:", Object(event).data);
// Once this event has been dispatched by the player, we can use
// cueVideoById, loadVideoById, cueVideoByUrl and loadVideoByUrl
// to load a particular YouTube video.
player = loader.content;
player.loadVideoById("nxrmJtaZBA0");
player.setSize(640, 360);
}
function onPlayerError(event:Event):void {
// Event.data contains the event parameter, which is the error code
trace("player error:", Object(event).data);
}
function onPlayerStateChange(event:Event):void {
// Event.data contains the event parameter, which is the new player state
trace("player state:", Object(event).data);
}
function onVideoPlaybackQualityChange(event:Event):void {
// Event.data contains the event parameter, which is the new video quality
trace("video quality:", Object(event).data);
}
We display the video by calling the loadVideoById(videoId:String) method that loads and plays the specified video.
3. That’s it, test the movie to see it in action.

You should change the youtube video ’cause the one you have is restricted, it does not show up in Italy.

@ GIUSEPPE: Hi, thanks for your remark, we’ve changed the video.
Indeed the old one has been restricted since.
Thanks again.

I have done this and it works perfectly, but i was wondering if it was possible to have this on a different frame other than frame one. I have tried it but the video just won’t play then.
Any help is highly appreciated.

Hello,
I’m not clear as to whether or not the new AS3 API still requires Javascript like the AS2 version did.

Hi, this is the first time that I have been able to get YouTube integrated into my flash site. I took your formula and placed it in one of my pages, adjusted the x and y coordinates, now when you go to that page it plays automatically. Now my problem is getting it to stop. What code do I use to have the movie stop when the user clicks another frame?
Rob.
