Hello @RL1000

yes you can use rpmfusion repo

check this one [Configuration - RPM Fusion](https://rpmfusion.org/Configuration)

for command line you need

`dnf install epel-release`  
to enable the epel repo

and the following from the link i mentioned

```auto
dnf install --nogpgcheck https://mirrors.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm

dnf install --nogpgcheck https://mirrors.rpmfusion.org/nonfree/el/rpmfusion-nonfree-release-8.noarch.rpm

dnf config-manager --enable powertools

dnf groupupdate core

dnf groupupdate multimedia --setop="install_weak_deps=False" --exclude=PackageKit-gstreamer-plugin

dnf groupupdate sound-and-video

```

hope that help and have a nice day 🙂
