Demos

Both run locally from a checkout and live at moq.dev.

Web demo

just            # relay + Big Buck Bunny + the web UI at http://localhost:5173

A Vite app in demo/web/ that uses the <moq-watch> and <moq-publish> web components. It shows:

• Watching a live broadcast with an adjustable latency budget and a stats overlay.
• Publishing your camera, microphone, screen, or a file from the browser with WebCodecs.
• Discovery: broadcasts appear as they're announced under the prefix.

just web serve https://cdn.moq.dev/anon points it at the public relay instead of a local one.

MoQ Boy

A crowd-controlled Game Boy Color. The emulator runs server-side, streams video and audio over MoQ, and any viewer can press buttons. Live at moq.dev/boy.

just boy                              # relay + emulator + viewer
just boy start path/to/game.gb        # your own ROM; run several for a grid

What it demonstrates:

• On-demand encoding. Emulation and encoding pause when the last viewer leaves and resume with a keyframe when one arrives. No timers, just subscription state.
• Discovery by prefix. Game sessions appear under boy/game/; viewers each publish a tiny broadcast under boy/viewer/. No control plane.
• Bidirectional data. Button presses go up on a raw JSON command track; a status track comes down with everyone's held buttons and latency. Same relay, same protocol as the media.
• Split trust. In production the game prefix is authenticated (only the server publishes games) while the viewer prefix is anonymous.

Tracks: catalog.json, video0.avc3 (160x144 H.264 at 60 fps), audio0.opus, and the raw status and command tracks. Code: rs/moq-boy (emulator and publisher), js/moq-boy (the <moq-boy> element, published as @moq/boy), and demo/boy. The same shape covers teleoperation: swap the emulator for a robot.
