## Usage
- Add the flake to your system flake's inputs.
- Include the nixos module in your config:
- Apply the overlay to your system's nixpkgs, e.g.
```nix
...
nixosConfigurations = {
mymachine = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
# ... your other modules ...
ajantv2.nixosModules.default
];
};
...
nixpkgs.overlays = [ ajantv2.overlays.default ];
```
- Enable the module by adding the following to your system config:
- Add the kernel driver:
```nix
ntv2.enable = true;
# Include the kernel module
boot.extraModulePackages = [pkgs.ajantv-driver];
# And load it automatically
boot.kernelModules = [ "ajantv2" ];
```
- Include the utils/demos and gstreamer plugin:
```nix
environment.systemPackages = [pkgs.ajantv-utils pkgs.aja-ntv2-gst]
```
