Actionscript 3 YouTube AS3 API中的某些函数返回错误的值

我现在正在处理某个AS3应用程序。代码与文档中的AS3示例非常相似：

// The player SWF file on www.youtube.com needs to communicate with your host
// SWF file. Your code must call Security.allowDomain() to allow this
// communication.
Security.allowDomain("www.youtube.com");

// 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
{
    stage.addChild(loader);
    loader.content.addEventListener("onReady", onPlayerReady);
}

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("nJ3MSCLBpaM");
    // Set appropriate player dimensions for your application;
    setPlayerSize();
    stage.addEventListener(Event.RESIZE, updatePlayerSize);
}

function setPlayerSize():void
{
    player.y = 0;
    player.x = 0;
    player.setSize(stage.stageWidth, stage.stageHeight);
}

function getVideoBytesTotal()
{
    return player.getVideoBytesTotal();
}
function getVideoBytesLoaded()
{
    return player.getVideoBytesLoaded();
}
function getVideoStartBytes()
{
    return player.getVideoStartBytes();
}

出于某种原因，当我在视频加载后（播放时）调用最后三个函数中的一个时，我从所有函数中得到的都是0。为什么会这样？

这些函数已被弃用。 使用

相反。

我面临着同样的问题！！！我注意到这只发生在firefox中。Chrome很好用。事实上我用的是Chrome，但它不起作用这个测试对你有用吗？这是在使用JSAPI。我在AS工作。

player.getVideoLoadedFraction()
