How do I install rpmfusion packages in Fedora 23 beta?

[Bill Oliver]

Just for kicks, I decided to play a bit with Fedora 23 beta.  Yes, I know it's not supposed to work like a production distro, but I thought it would be fun to poke around on it a little.   I sorta need to install a couple of packages from rpmfusion, though.  Unfortunately, they don't have a Fedora 23 setup out yet.

I tried to install the Fedora 22 repositories, but it didn't work.




I get the error:


Failed to synchronize cache for repo 'rpmfusion-free' from
'http://mirrors.rpmfusion.org/mirrorlist?repo=free-fedora-23&arch=x86_64':
Cannot prepare internal mirrorlist: No URLs in mirrorlist, disabling.



So, how would I go about, say, installing mplayer in Fedora 23 beta?

Thanks!
