I personally need
intel-media-driver from the non-free repo (for video hardware acceleration) and I don’t want to permanently enable the said repo, since I don’t run other software considered as “non-free” by Fedora.
The command shared by Glenn Johnson doesn’t work anymore — I don’t know if due to upgrading to Fedora 34 or some other change(s).
sudo dnf --enablerepo=rpmfusion-nonfree install programname
returns the error:
Error: Unknown repo: 'rpmfusion-nonfree'
