czkawka - missing ffmpeg dependency (used for comparing videos)

[edermats32]

Describe the bug

The czkawka package is missing ffmpeg as a dependency.
https://github.com/NixOS/nixpkgs/blob/6cc3e274c947096556c57d2b05dad5acda395b74/pkgs/by-name/cz/czkawka/package.nix

If ffmpeg is not found you get this error when trying to compare video files:

############### ERRORS(2) ###############
Cannot find proper installation of FFmpeg
Similar Videos don't work currently with snap, if you want help look at - ⁨https://github.com/snapcrafters/ffmpeg/issues/73⁩

Ignore the snap part, it throws this error when it can't find ffmpeg, regardless if snap or not.

Steps To Reproduce

1. Don't have ffmpeg installed on you system.
2. Try comparing videos in czkawka
3. czkawka throws error
4. Install ffmpeg
5. No error. Just works.

Expected behavior

No error. Just works.

Additional context

First issue I've reported here, hopefully I'm doing this right.

Before I propose any changes, let me know a thing or two.
When you install both ffmpeg and czkawka, then czkawka finds ffmpeg, correct?

[edermats32]

Correct. It finds it no problem.
