Re: FTBFS for f27
sonic-visualiser-freeworld can be retired as mad was moved to fedora, sonic-visualiser now
has mad support
The same applies to sox-plugins-freeworld.
As for xine-plugin, it seems to have been built
https://koji.rpmfusion.org/koji/buildinfo?buildID=4994
I believe it should be retired once Firefox-52 ESR support ends
