What browser?

Could you fire it up from a terminal window and go to you Youtube, then copy paste the error message here regarding the video playback.

Please tell me, how to fire firefox up from a terminal window.

I tried:

# firefox
Error: GDK_BACKEND does not match available displays

I receive this message in youtube, when I start firefox normally

https://paste.opensuse.org/70717848

in English something the message is something like:

“Your browser does not recognize any of the available videoformats.
Click here, to see our FAQ to HTML-5-videos.”

First of all:

firefox

Do not start firefox as root.

Second:
Please post:

zypper lr -d

zypper se -si firefox
