So I think you can do single-user build and then play with compiled binary and may be even use it in shell scripting as described in https://cinelerra-gg.org/download/CinelerraGG_Manual/Menu_Bar_Shell_Commands.html > 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. > > > >
