KDEnlive and frei0r plugins, make them work together

1

Hi guys,

I needed a quick video editor to try to remove a fish eye effect from a video and I’ve discovered that KDEnlive has one of such video effects.
I Installed it with nix-env on startup it opens a dialog complaining about a missing plugins package frei0r-plugins.
After a quick search I’ve installed with nix-env as welll but the editor keeps complaining of it being missing, even after deleting ~/.config/kdenliverc file.

Ah, I do not have the full KDE environment available. So before I try to install the complete desktop environment (something that I would rather avoid) anyona as a clue on how to fix the situation? As you can immagine, the effect i need is in the mentioned frei0r collection.

Any idea?

Don’t install libraries through nix-env or systemPackages, use
nix-shell instead. See FAQ/I installed a library but my compiler is not finding it. Why? - NixOS Wiki for
details. Or maybe do
https://github.com/NixOS/nixpkgs/blob/6dea8fe56e0341b57f441be9d1dcfb59cfe59b1c/pkgs/applications/video/shotcut/default.nix#L41
if you want to fix this in nixpkgs.

I also recently tried to use Kdenlive but there is still a bug with frei0r plugins : https://github.com/NixOS/nixpkgs/issues/29614

Also there are missing encoding options, the only ones available are lossless modes or images output. There should be at least x264 encoding and WebM with lossy parameters.

Maybe I should open a NixOS issue about the last point ?
