Enabling live video streams on youtube, etc.
Enable some RPMFusion repositories in the fedora-28 template(if you trust them or your template is an insecure domain):
[user@fedora-28 ~]$ sudo dnf config-manager –set-enabled rpmfusion-free
[user@fedora-28 ~]$ sudo dnf update
[user@fedora-28 ~]$ sudo dnf install ffmpeg
Enjoy.
