MixOS

This repo contains configuration for a linux distribution optimised for live audio/video mixing. Very much work in progress.

It is based on NixOS (atomic immutable deploys are quite suited for this usecase).

Templates and hosts

The configuration is split into templates for different kinds of machines. Each template is instantiated into one or more hosts.

• obs-station-qemu: for running an OBS workstation under qemu for testing
  • hala: development host for running locally
• obs-station-nvidia: for running an OBS workstation on machines with NVIDIA gpus
  • zver: an nvidia-based machine currently located in the protopit office
• fosdem-box: for headless mixing on fosdem boxes
  • fosdem-box-101: one of the testing boxes
  • fosdem-box-102: one of the testing boxes
  • fosdem-box-103: one of the testing boxes

Requirements

run nix develop or if you use direnv direnv allow .

install git hook/s to check nix linting rules:

make git-hooks

fix linting errors in nix:

make nixfmt

Build

nix build .#packages.x86_64-linux.hala

Run in QEMU

this will run the latest image found in ./result inside QEMU VM

nix build nixpkgs#OVMF.fd
./run-qemu.sh

Deploy on remote machine over SSH

Make sure the deploy.nodes.hala.hostname in flake.nix is correct and run:

nix run .#deploy -- .#hala
