如何测试网络会议问题?

如何测试网络会议问题?

我在 Ubuntu 21.04 安装(Plasma DE)中使用网络会议软件时遇到了问题。除了网络会议平台之外,其他所有功能都运行正常,例如视频流服务(Youtube、Vimeo 等):

  • 去会议
  • 思科 Webex
  • 飞涨
  • Google Meet
  • 微软团队
  • 大蓝按钮

无论我使用浏览器(Chrome、Firefox)还是桌面应用程序,都无法使用该服务:速度非常慢、滞后、我这边和其他参与者这边都出现音频问题,共享网络摄像头或桌面时视频性能不佳。

我该如何调查这个问题?任何有助于指出问题所在建议都会非常感激。

我建议你尝试使用软件电话,例如林峰或者吉特西(可能是 Skype,或者甚至是 TeamViewer?)。仅检查 VoIP。

还可以尝试使用网络摄像头,例如guvcview

并发布一些信息,例如:

$ uname -a
$ lsb_release -a

和计算机模型。
