gpu-screen-recorder is a screen recorder that has minimal impact on system performance by recording your monitor using the GPU only, similar to ShadowPlay on Windows.

Supported codecs

Video
  • H264 (default on Intel)
  • HEVC (default on AMD and NVIDIA)
  • AV1
Audio
  • Opus (default)
  • AAC
  • FLAC

Installation

  environment.systemPackages = with pkgs; [
    gpu-screen-recorder # CLI
    gpu-screen-recorder-gtk # GUI
  ];

Troubleshooting

libnvidia-fbc.so.1: cannot open shared object file: No such file or directory

The possibility of this error arising exists if you possess an NVIDIA graphics card, as the package does not include the NVIDIA X11 libraries in its wrapper by default.

  1. Make sure your drivers are installed.
  2. Install the missing the NVENC patch for your card. nvidia-patch is a great overlay which you can use
  3. Override the package build inputs and add the library to the wrapper.
{
  environment.systemPackages = [
    (pkgs.runCommand "gpu-screen-recorder" {
      nativeBuildInputs = [ pkgs.makeWrapper ];
    } ''
      mkdir -p $out/bin
      makeWrapper ${pkgs.gpu-screen-recorder}/bin/gpu-screen-recorder $out/bin/gpu-screen-recorder \
        --prefix LD_LIBRARY_PATH : ${pkgs.libglvnd}/lib \
        --prefix LD_LIBRARY_PATH : ${config.boot.kernelPackages.nvidia_x11}/lib
    '')
  ];
}
