在云主机上部署了Mediasoup-demo后，可以访问，并且加入房间，但是却无法看到对方的视频画面。如下图所示：
请问这种情况是哪里出问题了？

不知道是不是config.js设置出错了，config.js的内容如下：
/**

• IMPORTANT (PLEASE READ THIS):
• This is not the “configuration file” of mediasoup. This is the configuration
• file of the mediasoup-demo app. mediasoup itself is a server-side library, it
• does not read any “configuration file”. Instead it exposes an API. This demo
• application just reads settings from this file (once copied to config.js) and
• calls the mediasoup API with those settings when appropriate.
