在WebRTC视频和音频流的情况下浏览器实现之间的差异

Question

我想问一下，使用webrtc视频和音频插入的浏览器实现之间有什么区别。就我而言，它是Chrome和Firefox。问题是我使用WebRTC在Firefox上冻结了视频和音频。 Chrome，Opera和Chromium都可以正常运行，但Firefox除外。我将视频从应用程序传输到浏览器。如果我从Firefox连接到本地网络，那么一切也都可以正常工作。当我从外部网络通过Firefox连接时，我收到必须应用电击并打开服务器的消息。我从应用程序和浏览器两方面添加了它们。流持续几秒钟并冻结，这就是为什么我询问实现的原因。在一个浏览器中，我不需要眩晕，在其他浏览器中，我会收到错误消息。一个浏览器可以正常播放视频，另一个可以冻结。对我来说，最新的Firefox工作版本是50.0。我测试了从51到61-不起作用。需要你的帮助。谢谢。 这是从外部网络通过Chrome连接时的sdp。
