I actually kind of like the simplicity of wake() over changed() |

Media over QUIC
Media over QUIC (MoQ) is a live media delivery protocol utilizing QUIC streams. See the MoQ working group for more information.
This repository contains reusable libraries and a relay server. It requires a client to actually publish/view content, such as moq-js.
Join the Discord for updates and discussion.
Setup
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 to generate a self-signed certificate. Unfortunately, this currently requires Go in order to fork the tool.
./dev/cert
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.
Media
If you're using moq-pub then you'll want some test footage to broadcast.
mkdir media
wget http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4 -O dev/source.mp4
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.
You can run the development server with the following command, automatically using the self-signed certificate generated earlier:
./dev/relay
Notable arguments:
--bind <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
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.
The server also listens on TCP localhost:4443 when in development mode.
This is exclusively to serve a /fingerprint endpoint via HTTPS for self-signed certificates, which are not needed in production.
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.
The following command runs a development instance, broadcasing dev/source.mp4 to localhost:4443:
./dev/pub
Notable arguments:
<URI>connect to the given address, which must start with moq://.
moq-js
There's currently no way to consume broadcasts with moq-rs, at least until somebody writes moq-sub.
Until then, you can use moq.js both watch broadcasts and publish broadcasts.
There's a hosted version available at quic.video.
There's a secret ?server parameter that can be used to connect to a different address.
- Publish to localhost:
https://quic.video/publish/?server=localhost:4443 - Watch from localhost:
https://quic.video/watch/<name>/?server=localhost:4443
Note that self-signed certificates are ONLY supported if the server name starts with localhost.
You'll need to add an entry to /etc/hosts if you want to use a self-signed certs and an IP address.
