Flex 4 spark視頻播放器如何播放currentTime

Question

有4個Videosource，以便用戶可以在視頻的同一進程之間切換。

我該如何執行此操作？ 功能seek(time:duration):void dosn't真的有用。 :-(

，我用我的

     { 
      var playing:Boolean=VideoPlr.playing; 
      var time:Number = VideoPlr.currentTime; 
      VideoPlr.source = "http://helpexamples.com/flash/video/water.flv"; 
      // dosn't work this.VideoPlr.seek(VideoPlr.duration * time/100);

這裏是我的解決方案：

有四個文件可以在您的deisgne中切換。每個開關都會跳轉到新的源文件中。
