刚看到这个要求时，虽然实现后的效果并不是多么炫，不过要实现这些简单的效果却真的让我有些茫然无措，用Google搜索了N久也没有看到一篇能够使用的Demo或Example，无奈之下只好从最基本也是最全面的资料－－帮助文档分析起了，同时借鉴于ActionScritp3.0 CookBook的莫大帮助，才发现原来可以通过可视对象列表的叠加来实现，一点一点的磨损最终算是将一个很Ugly的图形放在了视频上，先把code粘到这，下一步的添加标题或边框应该就没有问题了。

Edit.mxml:（通过btnLoad按钮来添加叠放图形）

EditHandle.as:（Edit.mxml的脚本处理文件，只有其中的drawRect函数起作用，即绘制图形）

// ActionScript file
import mx.controls.VideoDisplay;
import mx.controls.videoClasses.CuePointManager;
import flash.text.TextField;
import snow.CircleExample;

private function displayCuePoint():void
{
    //var proxy:CuePointManager=new CuePointManager(player.cuePointManager);
    var cuePoints:Array=player.cuePoints;
    trace("as");
    for(var o:Object in cuePoints)
    {
        trace(o.name+":"+o.time);
    }
}

//Did not function!
private function drawRect():void
{
    //player.drawRoundRect(20,20,20,20,4,0xFF0000);
    var obj:CircleExample=new CircleExample();
    player.addChild(obj);
}

private function drawText():void
{
    var field:TextField=new TextField();
    field.text="Hello,I'm out!";
    field.textColor=0xFF0000;
    field.embedFonts=true;
    field.x=30;
    field.y=30;
    player.addChild(field);
    //DisplayObjectContainer(root).addChild(field);
    //trace(root);
}

CircleExample.as:（绘制图形的类）

package snow
{
    import flash.display.Sprite;
    import flash.display.Shape;

    public class CircleExample extends Sprite
    {
        public function CircleExample(  ) 
        {
          // Create three different colored circles and
          // change their coordinates so they are staggered
          // and aren't all located at (0,0).
          var red:Shape = createCircle( 0xFF0000, 10 );
          red.x = 10;
          red.y = 20;
          var green:Shape = createCircle( 0x00FF00, 10 );
          green.x = 15;
          green.y = 25;
          var blue:Shape = createCircle( 0x0000FF, 10 );
          blue.x = 20;
          blue.y = 20;
          
          // First add the red circle, then add the blue circle (so blue 
          // is drawn on top of red)
          addChild( red );
          addChild( blue );
          
          // Place the green circle between the red and blue circles
          addChildAt( green, 1 );
        }
        
        // Helper function to create a circle shape with a given color
        // and radius
        public function createCircle( color:uint, radius:Number ):Shape 
        {
          var shape:Shape = new Shape(  );
          shape.graphics.beginFill( color );
          shape.graphics.drawCircle( 0, 0, radius );
          shape.graphics.endFill(  );
          return shape;
        }
      }
}

花了一下午的时间总算是有点收获，下来要做的事就是写一个通用的处理添加效果的类，这样在主程序中只需要将其对象通过addChild或addChildAt添加到VideoDisplay中即可。而对于对所添加对象的编辑，如文字字体，颜色，大小，方向等的设置，图象的大小，位置等的设置，都放在效果类中处理即可。
