Media over QUIC (MoQ) is a live media delivery protocol utilizing QUIC streams.

See [quic.video](https://quic.video) for more information.

This repository contains a few crates:
2023-08-25 23:36:06 +00:00
- **moq-relay**: A relay server, accepting content from publishers and fanning it out to subscribers.
- **moq-pub**: A publish client, accepting media from stdin (ex. via ffmpeg) and sending it to a remote server.
- **moq-transport**: An async implementation of the underlying MoQ protocol.
- **moq-api**: A HTTP API server that stores the origin for each broadcast, backed by redis.
2022-06-29 16:17:02 +00:00
There's currently no way to view media with `moq-rs`; you'll need to use [moq-js](https://github.com/kixelated/moq-js) for that.
## Development
See the [dev/README.md] helper scripts for local development.
## Usage
2022-06-29 16:17:02 +00:00
### moq-relay
**moq-relay** is a server that forwards subscriptions from publishers to subscribers, caching and deduplicating along the way.
It's designed to be run in a datacenter, relaying media across multiple hops to deduplicate and improve QoS.
The relays register themselves via the [moq-api] endpoints, which is used to discover other relays and share broadcasts.
Notable arguments:
- `--listen <ADDR>` Listen on this address [default: [::]:4443]
- `--cert <CERT>` Use the certificate file at this path
- `--key <KEY>` Use the private key at this path
- `--fingerprint` Listen via HTTPS as well, serving the `/fingerprint` of the self-signed certificate. (dev only)
This listens for WebTransport connections on `UDP https://localhost:4443` by default.
You need a client to connect to that address, to both publish and consume media.
### moq-pub
This is a client that publishes a fMP4 stream from stdin over MoQ.
This can be combined with ffmpeg (and other tools) to produce a live stream.
Notable arguments:
- `<URL>` connect to the given address, which must start with https:// for WebTransport.
**NOTE**: We're very particular about the fMP4 ingested. See [dev/pub] for the required ffmpeg flags.
### moq-transport
A media-agnostic library used by [moq-relay] and [moq-pub] to serve the underlying subscriptions.
It has caching/deduplication built-in, so your application is oblivious to the number of connections under the hood.
Somebody build a non-media application using this library and I'll link it here!
See the published [crate](https://crates.io/crates/moq-transport) and [documentation](https://docs.rs/moq-transport/latest/moq_transport/).
### moq-api
This is a API server that exposes a REST API.
It's used by relays to inserts themselves as origins when publishing, and to find the origin when subscribing.
It's basically just a thin wrapper around redis.
