hi raven i wish i could compile ffmpeg 6.0 on el8 but one of the compilation dependencies is pkgconfig(shaderc) or if you prefer libshaderc-devel according to pkgs[DOT]org the package was present on your repository even though he cannot be found on it rhel[DOT]pkgs[DOT]org/8/raven-extras-x86_64/libs...

ok but instead of making an extra deposit if there are packages that update system packages

Why didn't you compile them in scl instead?
