Describe the bug

Jellyfin-ffmpeg overrides ffmpeg_6-full in a way that passes one version value (6.1) to the outer scope and a different value to the derivation scope (6.0.1). As a result withAribcaption = true is set and the build fails with Unknown option "--enable-libaribcaption"..

A rough fix looks like:

diff --git a/pkgs/development/libraries/jellyfin-ffmpeg/default.nix b/pkgs/development/libraries/jellyfin-ffmpeg/default.nix

   pname = "jellyfin-ffmpeg";

Looks like #271863 also may change things in this area.
