You're unfortunately not giving me enough information to understand what the exact problem is. How did you install ffmpeg exactly?

I should note that Homebrew now ships 5.x so the README is no longer valid.

I'm considering archiving this project in general, since it's deprecated for a while now.

Hello, thanks for your response i installed ffmpeg@4 from homebrew but when I tried to compile I got the above error you can see in below picture: Regards,

[slhck]

Try setting

export PKG_CONFIG_PATH="/opt/homebrew/opt/ffmpeg@4/lib/pkgconfig

Before running make.
