Indeed, it does, though interestingly just for tests, which are
currently broken.  I already had this back when I tried meson, but have
since forgot about it.  There are no actual references to it, so I've
made it a native input.  As far as using it is concerned, I think one
might be able to do without a certain set of plugins depending on the
codecs used.  Either way, I'm not really sure whether it should
propagate the main plugin set.

I also added the good plugins even if they are not mentioned, just to
be on the safe side.
