Actionscript 3 在Flash AS3中嵌入YouTube视频时缺少操作栏

我使用AS3在Flash中嵌入了一段YouTube视频，但它没有显示YouTube栏（播放/暂停、全屏等）按钮

视频在点击时播放，它的右下角只有YouTube徽标，点击后会带你进入YouTube。代码如下：

Security.allowDomain("www.youtube.com");


var videoPlayer: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);
}


function onPlayerReady(event:Event):void {
     trace("Ready");
     videoPlayer = loader.content;
     videoPlayer.setSize(214, 142); 
     videoPlayer.cueVideoByUrl("www.youtube.com/embed/VIDEO HERE", 0);
}

在我把问题贴出来后，我找到了答案。很抱歉浪费了阅读者的时间：

我让它加载的是无铬播放器，而不是嵌入式播放器。以下是解决方案：

Loading the chromeless player

If your application is using a chromeless player, use the following URL to load the player in your application:

http://www.youtube.com/apiplayer?version=3

Loading the embedded player

Use the following URL to load an embedded video player. In the URL, replace the string VIDEO_ID with the 11-character YouTube video ID that identifies the video that the player will show.

http://www.youtube.com/v/VIDEO_ID?version=3
