本文介绍了一个自定义的Flex平滑视频播放组件SmoothVideoDisplay，该组件继承自VideoDisplay，并在创建完成后自动调整视频平滑属性，以实现更佳的视频播放效果。

在FB 3中

package custom {

   import mx.controls.VideoDisplay;
   import mx.core.mx_internal;
   import mx.events.FlexEvent;

   use namespace mx_internal;

   public class SmoothVideoDisplay extends VideoDisplay
   {
       public function SmoothVideoDisplay():void
       {
           super();
           addEventListener( FlexEvent.CREATION_COMPLETE, onCreationComplete );
       }

       private function onCreationComplete( e:FlexEvent):void
       {
           if (videoPlayer.smoothing != smoothing)
           videoPlayer.smoothing = smoothing;
       }

       private var _smoothing:Boolean = false;

       [Bindable]
       public function set smoothing( val:Boolean):void
       {
           if ( val == smoothing)
           return;
           _smoothing = val;

           if (videoPlayer)
           videoPlayer.smoothing = _smoothing;
       }

       public function get smoothing():Boolean
       {
           return _smoothing;
       }

   }
}
