我正在使用Kevin Nilson在GitHub上托管的CastVideos-ios示例。
首先，如果这听起来有些奇怪或者没有必要，我很抱歉，但我有这个问题需要解决。
我想要做的是拒绝访问/连接，如果某个用户已经在电视上看到/投放媒体。
就目前而言，我未来的目标是创建一个管理众多用户的队列，让我解释一下：
在家中，有一台电视和一台Chromecast，家庭/用户共享同一个网络并希望在同一台电视上播放，我如何在不断开活动用户的情况下管理它？
从设备（iPhone），至少可以发出警告说“你即将断开某人的iPhone” - 是或否。
不知道我是否必须在发件人中实现此功能，如下面所示或使用JavaScript接收器。
感谢您的时间。
