I update a bunch of peoples machines from 15.3 to 15.4 - everyone including me, cannot play most video streams other than youtube.

I did a fresh install of 15.4 from openSUSE-Leap-15.4-DVD-x86_64-Build243.2-Media.iso downloaded today.

I chose the server option and added the MATE-Pattern during the install.

No difference

Followed this guide https://opensuse-guide.org/codecs.php
