`forceVP9`	Boolean	Force VP9 codec for webcam and screen sharing	`false`
`enableWebcamLayers`	Boolean	Enable simulcast or SVC for webcam	`true`
`enableSharingLayers`	Boolean	Enable simulcast or SVC for screen sharing	`true`
`webcamScalabilityMode`	String	`scalabilityMode` for webcam	'L1T3' for VP8/H264 (in each simulcast encoding), 'L3T3_KEY' for VP9
`sharingScalabilityMode`	String	`scalabilityMode` for screen sharing	'L1T3' for VP8/H264 (in each simulcast encoding), 'L3T3' for VP9

Installation

Clone the project:

$ git clone https://github.com/versatica/mediasoup-demo.git
$ cd mediasoup-demo
$ git checkout v3

Ensure you have installed the dependencies required by mediasoup to build.
Set up the mediasoup-demo server:

$ cd server
$ npm install

Copy config.example.js as config.js and customize it for your scenario:

$ cp config.example.js config.js

NOTE: To be perfectly clear, "customize it for your scenario" is not something "optional". If you don't set proper values in config.js the application won't work. You must configure a tls certificate.

Set up the mediasoup-demo browser app:

$ cd app
# For node 16
$ npm install
# For node 18, use legacy peer dependencies
$ npm install --legacy-peer-deps

Run it locally

Run the Node.js server application in a terminal:

$ cd server
$ npm start

In a different terminal build and run the browser application:

$ cd app
$ npm start

If you configured a self-signed tls certificate, and receive wss: connection errors, open the wss: url with https: protocol to accept the cert and allow wss: connections in your browser.

Enjoy.

Deploy it in a server

Globally install gulp-cli NPM module (may need sudo):

$ npm install -g gulp-cli

Build the production ready browser application:

$ cd app
$ gulp dist

Upload the entire server folder to your server and make your web server (Apache, Nginx, etc) expose the server/public folder.
Edit your server/config.js with appropriate settings (listening IP/port, logging options, valid TLS certificate, etc).
Within your server, run the Node.js application by setting the DEBUG environment variable according to your needs (more info):

$ DEBUG="*mediasoup* *ERROR* *WARN*" node server.js

If you wish to run it as daemon/service you can use pm2 process manager. Or you can dockerize it among other options.
The Node.js application exposes an interactive terminal. When running as daemon (in background) the host administrator can connect to it by entering into the server folder and running:

$ npm run connect

Run mediasoup server with Docker

Required environment variables: server/DOCKER.md.
Build the Docker image: server/docker/build.sh.
Run the Docker image: server/docker/run.sh.

$ cd server
$ docker/build.sh
$ MEDIASOUP_ANNOUNCED_IP=192.168.1.34 ./docker/run.sh

Considerations for config.js

Make sure https.listenIp is set to 0.0.0.0.
Make sure TLS certificates reside in server/certs directory with names fullchain.pem and privkey.pem.
The default mediasoup port range is just 2000-2020, which is not suitable for production. You should increase it, however you should then run the container in network="host" mode.
