As you see, you don’t have rpmfusion-free repository.
So, as said by @hhlp you should enable it.
As you can read in the document linked by @hhlp, this is the command to install the rpmfusion-free repository: sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
Is there any effort on the front of including ffmpeg into Fedora? I know the license is the problem here but I suppose a deal can be arranged with the creators, right?
