Looks like this is because cantata can't build against ffmpeg 7. A short-term fix would be to just use ffmpeg 6 in the derivation, but we should really switch to a fork of cantata which supports newer versions of ffmpeg (as the original has been archived): #315695

I'll open a PR shortly to switch it to v6.

Is there a way to override the current package to build against ffmpeg 6?

Update: The package builds successfully after overriding with:

environment.systemPackages = with pkgs; [ 
  (cantata.override {
    ffmpeg = ffmpeg_6-headless; 
  })
];
