所以，我们有一个启用了 WebRTC 的应用程序，它实际上在工作，它正在建立会话，我们能够连接到它们，人们正在发布流，其他人正在订阅和取消订阅这些流等等。但是我们不断收到来自 WebRTC 的错误，上面写着“PeerConnection.getStats”。已经得到统计数据了！错误发生在视频流本身。黑色背景上的白色文本，而不是视频。

此外，在控制台日志中，我们收到以下错误：

Uncaught TypeError: Cannot call method 'getStats' of undefined TB.min.js:208
PeerConnection.getStats: Already getting the stats! TB.min.js:54

关于可能导致这种情况的任何想法？我们如何从轮询统计信息中关闭 PeerConnection???? 在此先感谢您的任何建议！

我以前从未见过这种情况，但如果我猜测这可能是因为您在订阅完成之前多次订阅同一个流。
