cocoscreator 组件置于video上面方法：
Android端修改：
1. AppActivity-->onCreateView方法
        Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
        glSurfaceView.setZOrderMediaOverlay(true);
        glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
        glSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 8);
        SDKWrapper.getInstance().setGLSurfaceView(glSurfaceView, this);

2. 依赖项目 libcocos2dx-->Cocos2dxVideoHelper-->_createVideoView方法
    注释  videoView.setZOrderOnTop(true);

3. 触摸video上组件，需要注释video的touch事件。libcocos2dx-->Cocos2dxVideoView->onTouchEvent
   直接return false
