Interoperability

moq-cli speaks moq-transport drafts 14 through 18, negotiated over ALPN at connect. Point it at your relay and it picks the newest version you both support. (You should try moq-lite too, btw.)

Install

brew install moq-dev/tap/moq-cli   # macOS / Linux
cargo install moq-cli              # any platform with Rust
docker pull moqdev/moq-cli         # or podman

You also need FFmpeg for encode/decode.

Publish

A test pattern plus tone, so you don't need a media file:

ffmpeg -re -f lavfi -i testsrc=size=1280x720:rate=30 -f lavfi -i sine=frequency=440 \
    -c:v libx264 -preset ultrafast -tune zerolatency -g 60 -c:a aac \
    -f mp4 -movflags cmaf+frag_keyframe+empty_moov+default_base_moof - \
| moq --client-connect https://your-relay.example.com --broadcast bbb.hang import fmp4

Subscribe

moq --client-connect https://your-relay.example.com --broadcast bbb.hang export fmp4 | ffplay -

If it plays, you interop. That's the whole test.

Notes

• SUBSCRIBE_NAMESPACE is required. The subscriber discovers broadcasts by sending SUBSCRIBE_NAMESPACE and waiting for a matching announce, so your relay must support it. The publisher announces with PUBLISH_NAMESPACE.
• Self-signed or expired cert? Add --client-tls-disable-verify.
• Subscriber sees nothing? If your relay doesn't replay existing announcements, start the subscriber before the publisher.
• Verbose logs: prefix with RUST_LOG=info,moq_net=debug. It prints the negotiated version (e.g. connected version=moq-transport-18).
