将youtube视频id从视频源传递到flash

Question

我正在为我的荣誉项目开发一个flash web应用程序(ActionScript2.0)，但在嵌入youtube视频时遇到了问题。基本上，用户选择符号，然后根据选择的符号用特定的标签查询youtube api，然后从前30个视频中随机挑选一个视频。我使用以下代码实现了这一点：

on (release) {
url="http://gdata.youtube.com/feeds/api/videos?q=danger+passion&orderby=published&start-index="+random(30)+"&max-results=1&v=2"
getURL(url);
}

但这只会显示一个带有youtube视频链接的网页。

这是我将用来作为播放器基础的代码：

// create a MovieClip to load the player into
var ytplayer:MovieClip = _root.createEmptyMovieClip("ytplayer", 1);

// create a listener object for the MovieClipLoader to use
var ytPlayerLoaderListener:Object = {
onLoadInit: function() {
// When the player clip first loads, we start an interval to
// check for when the player is ready
loadInterval = setInterval(checkPlayerLoaded, 250);
}
};

var loadInterval:Number;


function checkPlayerLoaded():Void {
// once the player is ready, we can subscribe to events, or in the case of
// the chromeless player, we could load videos
if (ytplayer.isPlayerLoaded()) {
ytplayer.addEventListener("onStateChange", onPlayerStateChange);
ytplayer.addEventListener("onError", onPlayerError);
clearInterval(loadInterval);
}
}

function onPlayerStateChange(newState:Number) {
trace("New player state: "+ newState);
}

function onPlayerError(errorCode:Number) {
trace("An error occurred: "+ errorCode);
}

// create a MovieClipLoader to handle the loading of the player
var ytPlayerLoader:MovieClipLoader = new MovieClipLoader();
ytPlayerLoader.addListener(ytPlayerLoaderListener);

// load the player
ytPlayerLoader.loadClip("http://www.youtube.com/v/pv5zWaTEVkI", ytplayer);

有人能帮我从提要中获取视频的id (例如: pv5zWaTEVkI)吗？或者如何从flash发送查询，该查询将返回视频url/id，而不是馈送的url。任何帮助都将不胜感激，因为我很快就会上手。谢谢

你得到的不是一个网页而是一个RSS feed.

如果你只想要youtube的视频ID，你可以用watch?v=分割得到的字符串，视频字符串的前几个字符应该是‘(逗号)。

href='http://www.youtube.com/watch?v=aFyfbcZqdck' /><link

你可以通过拆分这个字符串来练习。
