如何停止播放視頻文件中的音頻？

Question

此代碼播放Youtube視頻。該文件使用FlashBuilder中的調試或運行按鈕工作，但在從Web服務器或Export Release文件夾中播放時存在錯誤：第二個視頻運行時，第一個視頻的音頻不斷播放。我怎樣才能卸載第一個音頻？

的解決方案，以停止對第二個按鈕點擊第一視頻/音頻：

在代碼中使用以下從的SWFLoader卸載第一視頻：

<fx:Script> 
     <![CDATA[ 
      import mx.controls.SWFLoader; 

     private var swfLoader:SWFLoader; 
     [Bindable] public var videoToPlay:String 
     public function playVideo(videoNum:int):void 
     { 
      if(swfLoader) 
      { 
       swfLoader.autoLoad = false; 
       swfLoader.unloadAndStop(); 
//    swfLoader.autoLoad = true; 
       hg.removeElement(swfLoader);    
       SoundMixer.stopAll(); 
      } 
      var videoAddress:String 
      if(videoNum == 1){ 
      videoAddress = "m2dg6teC7fg"; 
      }else{ 
      videoAddress = "0QRO3gKj3qw";    
      } 
      videoToPlay = "https://www.youtube.com/v/VIDEO_ID?v=" + videoAddress;  
      play(); 
     }    
     public function play():void 
     { 
      swfLoader = new SWFLoader(); 
      swfLoader.y = 100; 
      swfLoader.load(videoToPlay);  
      hg.addElement(swfLoader); 
     } 

     ]]> 
    </fx:Script> 


<s:HGroup id="hg"> 
    <s:Button id="button1" y="50" label="Button1" click="playVideo(1)" useHandCursor="true" buttonMode="true" /> 
    <s:Button id="button2" y="50" label="Button2" click="playVideo(2)" useHandCursor="true" buttonMode="true" />   

</s:HGroup> 

我在下面編輯的代碼，它適用於你的問題（我測試了我的方面）。試試吧，讓我知道它的作品？
