Rust WebRTC Client-Server example

About

An example with WebRTC-client and WebRTC-server. Network model is Client-Server-Client.

WebRTC-client works in two modes: sender or receiver. In sender mode, it sends text and video data to the server. The WebRTC server forwards data from one sender client to a receiver client.

The client side of this example uses async rust and web-sys including the use of WebRTC. The server side of this example uses async rust, WebSocket using tokio-tungstenite and WebRTC using webrtc-rs.

In order to simplify the code, all the errors are unwrapped.

State

• Signaling protocol,
• Signaling server,
• Multiple clients per server,
• Sender-Client-To-Server WebRTC-connection,
• Sender-Client-To-Server text,
• Sender-Client-To-Server video,
• Sender-Client-To-Server audio,
• Sender-Client-To-Server video and audio as a single stream,
• Server-To-Receiver-Client WebRTC-connection,
• Server-To-Receiver-Client text,
• Server-To-Receiver-Client video,
• Server-To-Receiver-Client audio,
• Server-To-Receiver-Client video and audio as a single stream,
• Each Sender-Client paired with the Receiver-Client,
• Data transfer from Sender-Client to Receiver-Client via server,
• Media transfer from Sender-Client to Receiver-Client via server.

Setup

• Run bash setup.sh

Usage

• Run bash watch.sh
• Open localhost:8080 in browser
• Edit the server address if necessary and click button Start sender or Start receiver.
• Type in sender TextArea, the message will be displayed on the receiver TextArea.
• If the receiver is started before the sender, you will see the video as soon as the sender is started.
