Eh, shouldn't the checksum be updated at least?

[devhell]

Duh.

@wmertens I'll leave this one alone, there have been obvious changes in regards to the patch, and I have no idea what the policy here is.

Well the problem is that handbrake basically ships with its own build system and in order to fix statefulness, reduce duplication and build time I split out their patches and made it build with the relevant Nix packages.

This is a bit of work but the other packages in NixPkgs benefit from it.

Alternative is to make a wrapper build that requires all the sources Handbrake wants, puts them together in a build directory and then runs the Handbrake builder. Less admin work, more resource wastage.
