Here's how we scaled it to support 1000 user per call https://youtu.be/LWwOSZJwEJI

The initial POC from 2022 https://www.youtube.com/watch?v=kZ9isFw1TQ8

video-call.rs

MVP of a teleconferencing system written in rust, both the backend and the UI.

How to try it out?

Setup

Technically you could run this with a single computer, but it is more fun if you use 2+.

Steps

1. Start the servers on the computer that you intend to use as the server using ACTIX_UI_BACKEND_URL=ws://<server-ip>:8080 make up (requires docker).

2. Enable WebTransport Developer Mode:

   • Go to chrome://flags/#enable-webtransport-dev-mode
   • Enable the flag
   • Close chrome

3. Open chrome using the launch_chrome.sh script, this will allow you to use webtransport locally.

4. If your server computer is behind a firewall, make sure that TCP ports 80 and 8080 are open

5. Connect all computers to http://<server-ip>/meeting/<username>/<meeting-id>

6. Make sure that you "allow" access to your mic and camera:

7. Click connect on both browsers, and enjoy:

👨‍💻 Project Structure

Contains 3 sub-projects

1. actix-api: actix web server
2. yew-ui: Yew frontend
3. types: json serializable structures used to communicate the frontend and backend.

Local Development

Dockerized workflow

1. Install docker https://docs.docker.com/engine/install/
2. Run one of the supported make commands

make test
make up
make down
make build

Without docker

Prerequisites

1. Create a postgresql database that you can accessed without a password. The default database name is actix-api-db, i.e. the default connection string is postgresql://$USER@localhost/actix-api-db

2. Install [trurl](see https://github.com/curl/trurl) and [nats-server]((see https://docs.nats.io/running-a-nats-service/introduction/installation)

Starting up the servers

1. Run the script ./start_dev.sh.

   It examines various environment variables to control the behavior; see the script itself for details. By default it runs using websockets rather than webtransport (WEBTRANSPORT_ENABLED=0) and without encryption (E2EE_ENABLED=0).

2. Connect your browser to http://localhost:8081/meeting/<username>/<meeting-id>

   You can make multiple connections (with varying usernames) from multiple browser windows or tabs.

   If you are using encryption (E2EE_ENABLED=1), you should lanuch Chrome with the necessary options for it to accept the local certificate by running ./launch_chrome.sh

The Actix websocket implementation contains fragments from https://github.com/JasterV/chat-rooms-actix in particular the usage of an actor to orchestrate all sessions and rooms.
