[fedora] (some) videos on YT laggy under chromium

I've recently had the 'pleasant' experience of watching some videos on Faildora's Fedora's Chromium; they were laggy as hell, especially when viewed in SD resolution. However, you could play them using Google Chrome or Firefox. There wasn't much to find on their forum/Reddit.

After some tries, here is the darn solution: this is an issue because of a screwed-up "free" ffmpeg package (ffmpeg-free), replacing the 'free' one with the version from RMPFusion did the trick!

so:

a/ install RPMFusion

• sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

b/ replace the ffmpeg

• sudo dnf in ffmpeg --allowerasing
