如何使用BrightScript for Roku创建YouTube式视频播放器?
我是ROKU开发的新手。几天前我就知道了。我想为我的Roku设备创建一个具有Youtube外观的视频播放器。我希望我的视频播放器以小窗口模式启动,并像Youtube那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 我已经研究过了。我尝试了Brighscript sdk附带的视频播放器示例。我也尝试过使用一些在线的定制视频播放器示例,但没有帮助实现我想要的。 如何在bright script视频播放器上添加按钮,以及如何制作该按钮以最小化和最大化bright script中的窗口。有人能为我提供相关代码吗?? 我已经下载了使用rovideoplayer的自定义视频播放器。 以下是Main.brs代码:如何使用BrightScript for Roku创建YouTube式视频播放器?,youtube,video-player,roku,brightscript,Youtube,Video Player,Roku,Brightscript,我是ROKU开发的新手。几天前我就知道了。我想为我的Roku设备创建一个具有Youtube外观的视频播放器。我希望我的视频播放器以小窗口模式启动,并像Youtube那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 我已经研究过了。我尝试了Brighscript sdk附带的视频播放器示例。我也尝试过使用一些在线的定制视频播放器示例,但没有帮助实现我想要的。 如何在bright script视频播放器上添加按钮,以及如何制作该按钮以最小化和最大化bright script中的窗
