I am not using sbopkg, but maybe I should be.

dav1d is *not* in the REQUIRES list of vlc, so I don't think it qualifies
as a "direct dependency".

That's good to know, thanks.

Hmmm... I don't see any dependency path in the .info files which leads me
from vlc to dav1d.  Maybe I'm missing it, but if it is not there, I wonder
if slackrepo would actually catch this.  I guess there's one way to find
out.
