My own post obove dosn´t work in my new opera after update.
So i found this on gibhub:

Open Opera Type in: opera://about (or vivaldi://about,)
then Ctrl+F to find 'Chrome' in the user-agent, (It is in Browser-Identification)
version number is Chrome/XXX.other_numbers .
expl. Chrome/101 (2 or 3 signs).
Then go to this Download-Site
https://onedrive.live.com/?authkey=!AC7ddalBsUiWsUE&id=75D48EF8D3750510!234&cid=75D48EF8D3750510
Go to your version of Chrome and Download the
Copy it with root to Opera-Directory
/usr/lib/x86_64-linux-gnu/opera (overwrite)
(you can rename the origin libffmpeg.so before
ex: libffmpeg.so-orig)
This works for me now.
