moq-cli

moq-cli

A command-line tool for publishing and subscribing to media over MoQ. It works with FFmpeg for encoding and decoding.

Install

cargo install moq-cli

Docker

docker pull moqdev/moq-cli

Multi-arch images (linux/amd64 and linux/arm64) are published to Docker Hub.

Usage

moq-cli reads media from stdin (or writes media to stdout) and exchanges it with a MoQ relay. Pick a subcommand based on whether you want to publish or subscribe, and whether your relay is local or remote.

Publish to a remote relay

ffmpeg -i input.mp4 -f mp4 -movflags cmaf - | \
    moq-cli publish --url https://relay.example.com --broadcast my-stream fmp4

Subscribe from a remote relay

moq-cli subscribe --url https://relay.example.com --broadcast my-stream --format fmp4 | \
    ffplay -

Self-host: publish into a local relay (serve)

Runs a relay and publishes a single broadcast read from stdin into it. Useful for local testing without a separate relay process.

ffmpeg -i input.mp4 -f mp4 -movflags cmaf - | \
    moq-cli serve --broadcast my-stream fmp4

Self-host: subscribe to an inbound broadcast (accept)

Runs a relay and writes the first incoming broadcast's media to stdout. The inverse of serve.

moq-cli accept --broadcast my-stream --format fmp4 | ffplay -

Input formats (publish / serve)

• avc3 raw H.264 Annex-B from stdin
• fmp4 fragmented MP4 from stdin
• hls --playlist <url-or-path> ingest from an HLS playlist
