如何使用Starling引擎在舞台上录制电影剪辑

Question

我买了一个ane录制屏幕，它使用了starling事件。它记录了八哥阶段，即四个旋转的圆圈。但我想录制我的电影剪辑。我可以看到我的电影剪辑出现在八哥动画中。但它仅记录八哥动画。如何记录包含电影剪辑和动画的Flash舞台？你能帮我么？预先感谢。

这是用于启动的.as文件。

        Starling.multitouchEnabled = true;
        Starling.handleLostContext = !iOS;

        var viewPort:Rectangle = RectangleUtil.fit(
            new Rectangle(0, 0, stageWidth, stageHeight), 
            new Rectangle(0, 0, stage.fullScreenWidth, stage.fullScreenHeight), 
            ScaleMode.NONE); 
//  mStarling.display.stage = Starling.current.stage;
        mStarling = new Starling(Game, stage, viewPort); 
    //  mStarling = new Starling(Game, stage);
        mStarling.stage.stageWidth  = stageWidth;
