[winswitch] Beta Fedora 28 Repo - Missing ffmpeg package?

[WireRydr]

Hello there.  I'm attempting to utilize the Fedora-28 beta respository, 
however I am encountering the following error, which leads me to suspect 
that at least one required package is presently missing:

When I check online, I see that in the F29 repo this package is present:

ffmpeg-xpra-4.0.2-1.fc29.x86_64.rpm

However, no corresponding package exists in the F28 repo.  Is this 
something that can be rectified, or is it intentional?

Thanks for your time!
