带有视频内容的JFXPanel 在swing中进行窗口跳转会丢失视频内容

我按照oracle显示的demo做的，可以在启动时有视频内容，但是经过跳转之后，视频内容就丢失了；

下面是我得demo；请熟悉这方面的帮忙看看，多谢

        return (scene);
    }

    public static void main(String[] args) {

            @Override

                VideoDemo.initVideoFrame ( );
            }
        });

    }

}

窗口跳转以后是否可以重新加载视频呢？
