我一直试图在Chromecast应用上播放两个视频(不一定是同时播放)。其中一个是通过Youtube API嵌入的,另一个是通过标记加载的标准HTML5视频。
事实证明,如果我的HTML5页面中还有一个标准标签,则Youtube视频根本无法在Chromecast上播放。但是,如果我删除该视频标签,那么Youtube视频将会很好地播放。
非常感谢任何建议!

Chromecast仅支持一个有效的视频流。

我遇到了同样的问题。
要解决这个问题的关键因素是,卸载演员,当你尝试播放Youtube时,不要让视频标签留在DOM中并设置SRC属性。
至于YouTube,在尝试使用HTML5视频代码时,不要让包含其视频播放器的IFRAME留在DOM中。
在尝试通过对立机制触发播放之前,您需要拆掉之前的播放器。
这是我用来排除故障并解决问题的示例接收器。这是一个有效的例子。

测试:
加载上面的样品接收器,并在chrome调试控制台内交替使用以下内容:
playDirect()
或
playYT()
