如何使用 Brightcript for Roku 创建类似 you-Tube 的视频播放器？
How to create a you-Tube like video player using Brightcript for Roku?
我是ROKU开发新手。几天前我得到了它。我想为我的 Roku 设备创建一个 具有 Youtube 外观和风格的视频播放器。我希望我的视频播放器以小型 window 模式启动，并像 Youtube 一样在右侧显示视频列表。此外，我还想添加一个 按钮来最大化和最小化屏幕。
我研究过。我试过 Brighscript sdk 附带的视频播放器示例。我还尝试使用一些在线提供的自定义视频播放器示例，但没有帮助实现我想要的。
如何在明亮脚本中的视频播放器上添加按钮，以及如何使该按钮最小化和最大化明亮 window script.can 谁能给我提供代码？？
我下载了使用rovideoplayer的自定义视频播放器。
这是 Main.brs 代码：

任何关于我应该遵循的方法的建议，或者能为我指明正确方向并能给我一个良好开端的事情，我将不胜感激。
您可以将 roScreen 与 roVideoPlayer 一起使用。但是要用roScreen获得完全定制的设计是需要很多努力的。
