hello, I recently tried out flake to install gstreamer.
I followed the guide found here
I created a flake.nix file under /etc/nixos/
and copy the whole thing from that guide in, which looks like this:
# file: flake.nix
{
description = "A GStreamer development flake";
outputs = { self, nixpkgs }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
in {
devShells.${system}.default = pkgs.mkShell {
buildInputs = with pkgs; [
# Video/Audio data composition framework tools like "gst-inspect", "gst-launch" ...
gst_all_1.gstreamer
# Common plugins like "filesrc" to combine within e.g. gst-launch
gst_all_1.gst-plugins-base
# Specialized plugins separated by quality
gst_all_1.gst-plugins-good
gst_all_1.gst-plugins-bad
gst_all_1.gst-plugins-ugly
# Plugins to reuse ffmpeg to play almost every video format
gst_all_1.gst-libav
# Support the Video Audio (Hardware) Acceleration API
gst_all_1.gst-vaapi
#...
];
};
};
}
then i did nix develop
command to install GStreamer
but when i rebuild my system with nixos-rebuild switch
, it throws me an error:
error: flake 'path:/etc/nixos' does not provide attribute 'packages.x86_64-linux.nixosConfigurations."Windows11".config.system.build.nixos-rebuild', 'legacyPackages.x86_64-linux.nixosConfigurations."Windows11".config.system.build.nixos-rebuild' or 'nixosConfigurations."Windows11".config.system.build.nixos-rebuild'
It feels like I’m missing something obvious here and i hope someone can please help me
