How to install mesa nonfree HW acceleration codecs

Hello, good morning, Mabox is a super operating system. Nothing fails me. The system is very stable and everything works well. Is there a way to install the multimedia codes?

THESE ARE THE ONE THAT APPEARS TO ME

AND THIS IS WHAT THEY HAVE TO BE:

You gave the thread a title about multimedia codecs - which may be misleading for most users, because the post concerns non-free Mesa drivers/codecs for hardware acceleration (AMD graphics only). I clarified the title of the post.

Mesa provided by Manjaro does not include non-free codecs for some time.
If you need them, you can use an unsupported repo prepared by the community:

https://nonfree.eu/

Use at your own risk…

Do we have anyone on board who uses this repo?

Thanks, I’d better leave it like this so I don’t break something.
