Netstream到Movieclip不起作用

Question

我有问题。 我想在netstream中添加一个onClick方法。 我读到你需要打开netstream movieclip。 我这样做了，问题是因为视频没有显示

private var nc:NetConnection;
    private var ns:NetStream;
    private var video:Video;
    private var adSoundTransform:SoundTransform;
    private var mc_flv:MovieClip;



    public function FakeAd(lineColor:Number, fillColor:Number, label:String)
    {


        function asyncErrorHandler(event:AsyncErrorEvent):void
        {

        }
        nc = new NetConnection();
        nc.connect(null);
        ns = new NetStream(nc);
        ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, this.asyncErrorHandler);

        ns.play("http://www.helpexamples.com/flash/video/cuepoints.flv");
        video = new Video(640,360);

        video.attachNetStream(ns);
        video.smoothing = true;
        //addChild(video);
        mc_flv.addChild(video);
        //ns.resume();


        //video.x = stage.stageWidth/2;
        //video.y = stage.stageHeight/2;

    mc_flv.addEventListener(MouseEvent.CLICK,onClick);

    function onClick(e:MouseEvent):void
        {

            navigateToURL(new URLRequest("http://Google.com"));

        }
