# Media over QUIC
|
|
|
|
Media over QUIC (MoQ) is a live media delivery protocol utilizing QUIC streams.
|
|
See the [Warp draft](https://datatracker.ietf.org/doc/draft-lcurley-warp/).
|
|
|
|
This repository is a Rust server that supports both contribution (ingest) and distribution (playback).
|
|
It requires a client, such as [moq-js](https://github.com/kixelated/moq-js).
|
|
|
|
## Setup
|
|
|
|
### Media
|
|
|
|
This demo simulates a live stream by reading a file from disk and sleeping based on media timestamps. Obviously you should hook this up to a real live stream to do anything useful.
|
|
|
|
Download your favorite media file and convert it to fragmented MP4.
|
|
This requires [ffmpeg](https://ffmpeg.org/)
|
|
|
|
```
|
|
wget http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4 -O media/source.mp4
|
|
./media/generate
|
|
```
|
|
|
|
### Certificates
|
|
|
|
Unfortunately, QUIC mandates TLS and makes local development difficult.
|
|
If you have a valid certificate you can use it instead of self-signing.
|
|
|
|
Use [mkcert](https://github.com/FiloSottile/mkcert) to generate a self-signed certificate.
|
|
Unfortunately, this currently requires Go in order to [fork](https://github.com/FiloSottile/mkcert/pull/513) the tool.
|
|
|
|
```
|
|
./cert/generate
|
|
```
|
|
|
|
Unfortunately, WebTransport in Chrome currently (May 2023) doesn't verify certificates using the root CA.
|
|
The workaround is to use the `serverFingerprints` options, which requires the certificate MUST be only valid for at most **14 days**.
|
|
This is also why we're using a fork of mkcert, because it generates certificates valid for years by default.
|
|
This limitation will be removed once Chrome uses the system CA for WebTransport.
|
|
|
|
## Usage
|
|
|
|
Run the server:
|
|
|
|
```
|
|
cargo run
|
|
```
|
|
|
|
This listens for WebTransport connections on `https://localhost:4443` by default.
|
|
Use a [MoQ client](https://github.com/kixelated/moq-js) to connect to the server.
