我根据WebRTC 文档在 Chrome 浏览器上启动 Express + node.js 网络服务器时部署了这个 Agora.io Webrtc 示例。

This appears to be Chrome
(index):78 Init AgoraRTC client with vendor key: ***

我得到了失败的结果并尝试重新安装一些包含 v54、v56、v57、v59 和最新版本的 google chrome 版本。但是每个 chrome 版本都有相同的错误

adapter.js:340 Uncaught (in promise) DOMException: Failed to parse SessionDescription. Failed to parse video codecs correctly.

是什么意思？

“无法正确解析视频编解码器”错误是由 setMaxBW 接口引起的已知 sdp 兼容性问题。不推荐使用 1.8.0 版本，因为它已过时。我建议升级到最新版本。
