I forgot one question:
Will it be possible and how to access and use ffmpeg-5.x included with 
Cin-GG in a terminal as usual?

The latest openSUSE Leap 15.4 distro I use, has so far no official 
ffmpeg-5.x package or codec enabled from Packman.
I have add-installed ffmpeg-5.1.2 from OBS (Open Build Service), but 
don't know if it works.
