  • Supported Roles: Publisher, Subscriber, PubSub
• Exposes MSF catalog JSON helpers for browser integration

• Client for IP cameras over RTSP/ONVIF (Raspberry Pi and Mac)
• Includes moqt-onvif-client to bridge RTSP video + ONVIF commands over MoQ

cd moqt-server-sample
mkdir keys
cd keys
openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -out cert.pem -subj '/CN=Test Certificate' -addext "subjectAltName = DNS:localhost"

• make server

if you want to watch tokio tasks, use tokio-console

cargo install tokio-console
tokio-console

make server-trace

or

# Default setting is `DEBUG`
cargo run -p moqt-server-sample -- --log <Log Level>

cd js && npm install
make client

• Add a certificate and Enable WebTransport feature in Chrome

# For Mac users
make chrome

# For Linux users
make chrome:linux

The automated Media Publisher → Subscriber E2E flow is supported on Linux.

node scripts/setup-media-e2e.mjs

This command:

• generates moqt-server-sample/keys/key.pem and cert.pem when missing
• installs js dependencies
• builds moqt-client-wasm into js/pkg
• installs Playwright Chromium for the E2E browser run

node scripts/run-media-e2e.mjs

This command starts moqt-server-sample, starts the Vite server for js, runs the Playwright E2E for the Media Publisher / Subscriber examples, and cleans up the child processes.

GitHub Actions also runs the same Linux media E2E flow in .github/workflows/media-e2e.yml.

The Playwright test itself can also be run directly:

cd js
npm run e2e:media

Environment variables for advanced runs:

• MEDIA_E2E_WEB_PORT (default: 4173)
• MEDIA_E2E_MOQT_URL (default: https://127.0.0.1:4433)
• MEDIA_E2E_NAMESPACE (default: auto-generated by run-media-e2e.mjs)

cargo fmt --all --check
cargo clippy --workspace --all-targets --all-features
cargo test
cd js && npm run lint
cd js && npx prettier --check "**/*.{js,jsx,ts,tsx,json,css,md}"
cd js && npm run e2e:media

cp .env.example .env
make onvif

ONVIF_IP / ONVIF_USERNAME / ONVIF_PASSWORD are read from .env.

MoQ bridge:

make onvif-moq

MOQT_URL is read from .env.
