issue

My processor has hardware decoder for AV1 codec. Till I was using Fedora 41, everything was fine, but after upgrading to F42 video playback is stuttering (AV1, VP9, etc) in Firefox, MPV,but not in google-chrome.

What should I do?

Following was already installed from F41 but I again installed it in F42

sudo dnf group install multimedia

What igpu?, intel or amd?
