我是ROKU开发的新手。几天前我拿到了它。我想为我的 Roku 设备创建一个具有 Youtube 外观和感觉的视频播放器。我希望我的视频播放器以小窗口模式启动,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

我对此进行了研究。我已经尝试了 Brighscript sdk 附带的视频播放器示例。我还尝试使用一些在线可用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脚本中的窗口。谁能提供我的代码?

我已经下载了使用 rovideoplayer 的自定义视频播放器。这是 Main.brs 代码:

Sub RunUserInterface()
    o = Setup()
    o.setup()
    o.paint()
    o.eventloop()
End Sub

        progress:  0 'buffering progress

        paused:    false 'is the video currently paused?
        feedData:  invalid

        playingPrev: 0

您可以将 roScreen 与 roVideoPlayer 一起使用。但是使用 roScreen 获得完全定制的设计需要付出很多努力。
