我发现了很多类似的问题，但它们主要是过时的和过时的，其中一些提供了一些指示，但我没有用。
基本上，我想使用webrtc和phonegap iosrtc插件来创建简单的双向视频聊天。
我遵循了所有内容，并设法在应用程序中显示了自己的视频，但是“远程”视频没有显示，并且我想弄清楚问题出在哪！
我已在phonegap中启用了调试功能，但没有收到任何错误消息。
这是我完整的代码：

如您在我的代码中看到的，我有这个：
if (event.type === 'remote') {
alert('remote');
video.setAttribute('class', 'othersvideo');
}
但是由于某种原因，它永远不会触发！
我花了最后三天的时间来解决这个问题，但是我没有任何运气。
因此，我们将不胜感激。
谢谢。
