 Problem: package ffmpeg-5.1.6-1.el9.x86_64 from rpmfusion-free-updates requires ffmpeg-libs(x86-64) = 5.1.6-1.el9, but none of the providers can be installed

  - nothing provides libdav1d.so.6()(64bit) needed by ffmpeg-libs-5.1.6-1.el9.x86_64 from rpmfusion-free-updates

I could not find much on this online unfortunately.

Don't need ffmpeg and so on for my cases, but maybe valuable to get some help from and for others.
