OBS Plugin

The plugin adds a MoQ streaming service and a MoQ Source to a stock OBS Studio install.

• Publish: Settings > Stream, choose "MoQ", enter the relay URL (with ?jwt= if needed) and broadcast path, Start Streaming.
• Subscribe: add a "MoQ Source", enter the relay URL and broadcast path, and the stream appears in the scene.
• Dock: a MoQ dock shows connection state and opens the advanced settings.

Install

Prebuilt archives for macOS (Apple Silicon) and Windows (x64) are attached to each obs-moq release. Extract into your OBS plugins directory. The archives are unsigned, so Gatekeeper and SmartScreen warn on first load. Linux builds from source:

nix develop
just obs build

macOS and Windows source builds use just obs setup && just obs build with Xcode or Visual Studio 2022; see cpp/obs/.

Advanced settings

Off by default; the defaults suit a normal relay. When enabled they cover the things you'd otherwise pass to moq on the command line: pinning a protocol draft or QUIC backend, trusting a self-signed relay by fingerprint or a private CA, an SNI override, reconnect pacing, congestion control (delay-based BBR or loss-based CUBIC), stream limits and timeouts, qlog traces for diagnosing stalls, and the WebSocket fallback race. A rejected value stops the stream with the reason in the log rather than silently using a default.

The plugin is C++ over libmoq's C ABI and ships with every libmoq release.
