mediasoup UP but Not forwarding

mediasoup-demo
1

I am having a problem get mediasoup_v3_example working.

I have created a remote server and deploy the code. From the terminal everything looks fine and I can see the clients connecting. I can load up the “html” pages and start the media, I’m able to hit publish but whenever people subscribed they only received an empty box.

Im testing with A Ubuntu laptop, a Macbook and an Android phone.

Here is the output from only trying to run the broadcast example

$ node mediasoup_v3_broadcast.js

I have also changed the top of the server file to

const fs = require('fs');
let serverOptions = {
  hostName: "178.128.128.151",
  listenPort: 443,
  useHttps: true,
  httpsKeyFile:"../MyKeyFile",
  httpsCertFile:"../MyCertFile",
};
let sslOptions = {};
if (serverOptions.useHttps) {
  sslOptions.key = fs.readFileSync(serverOptions.httpsKeyFile).toString();
  sslOptions.cert = fs.readFileSync(serverOptions.httpsCertFile).toString();
}

Ps I can get mediasoup-sample-app running

Thanks for any help on this : )

It’s probably best to take this issue up with that example project’s support channel.

Hi @brunton_doug

I have created an issue on the Repo (/github.com/mganeko/mediasoup_v3_example/issues/3)
+ posted it on stack-overflow (/stackoverflow.com/questions/62544922/mediasoup-up-but-not-forwarding),
but no feedback or reply :cry:
