The docstring describes an alist format but the setter function and
:options keyword for the defcustom expects a nested list.

However, the setter functions turns the nested list into the alist
format described in the docstring.  I.e.,

    (("mpv %s" "audio/.*") ("mpv %s" "video/.*"))

transforms to

    (((view . "mpv %s") (type . "audio/.*")) (view . "mpv %s") (type . "video/.*"))
