im trying to install libav using brew but it returns
Error: libav has been disabled because it is not maintained upstream!
I've tried to follow THIS solution but im missing the disable! date: "DATE", because: :unmaintained line when editing the libav brew formula.
I've already tried reinstalling brew
brew version, 4.0.1-91-g6b7ecd1
macOS version, 13.1 (22C65)
Yeah, it has been unmaintained for quite some time, see this archive page. This is the related deprecation PR, and homebrew usually disable the build after one year mark, which is usually the new release for macOS.
