标签: actionscript-3 flash youtube urlrequest

我在flash上​​创建了一个信息亭,但是我遇到了一个问题,在外部加载我的内容时非常烦人。我已经导出了所有的swf文件并创建了一个独特的swf来加载它上面的主菜单。主要问题是从youtube流式传输视频。它加载完美,但当我导航到另一个页面时,页面会发生变化,但如果播放过一次,视频就不会停止。(声音一直在播放)。这是我的代码:

loader1.fla:

// Container
var pageLoader:Loader = new Loader();

// Url Requests
var loadRequest1:URLRequest = new URLRequest("basics1.swf");
var loadRequest2:URLRequest = new URLRequest("climatechange.swf");  

// Initial Page Loaded
pageLoader.load(loadRequest1)
addChild(pageLoader)

// Button Functions
function goHome (e:MouseEvent):void{
pageLoader.load(loadRequest1)
addChild(pageLoader)
}
hpage.addEventListener(MouseEvent.CLICK, goHome);

//go to climate change page
function climatePage (e:MouseEvent):void{
pageLoader.load(loadRequest2);
addChild(pageLoader);
}
climatep.addEventListener(MouseEvent.CLICK, climatePage);

climatechange.fla:

Security.allowDomain("http://www.youtube.com")

// load video
var pageLoader:Loader = new Loader();

// Url Requests
var loadRequest1:URLRequest = new URLRequest("overviewvideo.swf");

// Intial Page Loaded
pageLoader.load(loadRequest1)
addChild(pageLoader)

overviewvideo.fla:

/*youtube video*/

var player:Object;

var loader:Loader = new Loader();

var context:LoaderContext = new LoaderContext();
context.checkPolicyFile = true;
context.securityDomain = SecurityDomain.currentDomain;
context.applicationDomain = ApplicationDomain.currentDomain;

loader.contentLoaderInfo.addEventListener(Event.INIT, onLoaderInit);
Security.allowDomain("http://www.youtube.com")
loader.load(new URLRequest("http://www.youtube.com/v/6s8iiIFgPMU&list=PL9C6D9D2AF8999F85&index=12"));

function onLoaderInit(event:Event):void {
    addChild(loader);
    loader.x= 40;
    loader.y=130;
    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;
    // Set appropriate player dimensions for your application
    player.setSize(480, 260);
}

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);
}

有人可以帮忙吗?如果有人可以帮助我,我会很高兴。谢谢

答案 0 :(得分:0)

在将新swf加载到加载程序之前,需要先调用:

pageLoader.unloadAndStop();

尝试卸载子SWF文件内容并停止从加载的SWF文件执行命令。此方法尝试通过删除对子SWF文件的EventDispatcher,NetConnection,Timer,Sound或Video对象的引用来卸载使用Loader.load()或Loader.loadBytes()加载的SWF文件。因此,子SWF文件和子SWF文件的显示列表会出现以下情况:

声音停止了。 舞台事件侦听器已删除。 将删除enterFrame,frameConstructed,exitFrame,activate和deactivate的事件侦听器。 计时器停止了。 摄像机和麦克风实例已分离 电影剪辑已停止。
