Media over QUIC

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: - **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. There's currently no way to view media with this repo; you'll need to use [moq-js](https://github.com/kixelated/moq-js) for that. ## Development Use the [dev helper scripts](dev/README.md) for local development. ## Usage ### 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](moq-api) endpoints, which is used to discover other relays and share broadcasts. Notable arguments: - `--listen ` Listen on this address, default: `[::]:4443` - `--cert ` Use the certificate file at this path - `--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: - `` connect to the given address, which must start with `https://` for WebTransport. **NOTE**: We're very particular about the fMP4 ingested. See [this script](dev/pub) for the required ffmpeg flags. ### moq-transport A media-agnostic library used by [moq-relay](moq-relay) and [moq-pub](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. 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 that is only needed to run multiple relays in a (simple) cluster. ## License Licensed under either: - Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) - MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)
