==== 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.

# Make sure your [[Nvidia|drivers]] are installed.
# Install the missing the NVENC patch for your card.  [https://github.com/icewind1991/nvidia-patch-nixos nvidia-patch] is a great overlay which you can use 
# Override the package build inputs and add the library to the wrapper.<syntaxhighlight lang="nix">
