Closes issue #1725.
This allows mpv module to be customized with support for more advanced
features than the `programs.mpv.scripts` current support. For example,
with this change now this is possible:
```nix
{
programs.mpv.package = (pkgs.wrapMpv (pkgs.mpv-unwrapped.override {
vapoursynthSupport = true;
}) {
extraMakeWrapperArgs = [
"--prefix" "LD_LIBRARY_PATH" ":" "${pkgs.vapoursynth-mvtools}/lib/vapoursynth"
];
});
}
```
Since `programs.mpv.package` doesn't necessary reflect the final
derivation anymore (see #1524), we introduce `programs.mpv.finalPackage`
that has the resulting derivation.
This includes 2 tests:
- One to check if everything is alright with mpv
- Other to validate our assertion that package and scripts can't be
passed both at the same time
* docs: document recent mpv module changes
* mpv: add thiagokokada as maintainer
