You can use ‘substitute-keyword-arguments’, along these lines:


   (define ffmpeg-3.4
     (package
       (inherit ffmpeg)
       ;; …
       (arguments (substitute-keyword-arguments (package-arguments ffmpeg)
                    …))))

See the other packages that use it as examples.

HTH!

Ludo’.
