Disclaimer

This is intended to show common use cases of WebRTC cross platforms and to give you some ideas, it may have bugs, use with caution!

Setup

Start signaling server

First you need to start the signaling server, Open terminal at signaling-server and run:

npm install # or yarn install (to install dependencies)
npm run dev # or yarn dev

Once started the address of signling server will be printed in your terminal

Start clients

The usage of all clients are same, you just need to join clients in same room by input same roomID.

Web

To start web client, open terminal at web and run:

npm install

npm run dev

Then open 2 browsers at localhost:5173 to test

Android

Change the value of serverAddress in android/app/src/main/res/values/strings.xml to server IP which is printed when you start the signaling server

iOS

First run the following command in ios folder:

pod install

Then change SERVER_URL in CallViewController to signaling server address

Troubleshooting

iOS - Compiling for iOS 11.0, but module...

Change Minimum Deployments of the pod that has issue to latest

iOS - Sandbox: rsync.samba(13105)...

Solution: Update your Xcode project build option ENABLE_USER_SCRIPT_SANDBOXING to 'No'.

End-to-end encryption

Note

Currently only supported for Web-Web communication

Under web/src/App.vue, set enableE2EE=true to enable E2EE

By default, E2EE use Web Worker for encrypt/decrypt, if you want to do that on Main thread then set useEncryptionWorker=false

If you want to verify if E2EE is working, turn on shouldSendEncryptionKey=true, then the remote peer won't receive encryptionKey and it will show raw video which is encrypted and not visible
