I have installed ffmpeg from homebrew. How can I force define ffmpeg include directory path? Because it can't find it

[evanpurkhiser]

you can try using my homebrew tap

brew tap evanpurkhiser/personal
brew install keyfinder-cli

[floydback]

I'm not sure because at first I tried to install from source (maybe some package installed in the wrong place). But after I made brew uninstall fftw catch2 your homebrew tap worked. Without uninstalling it showed error with fftw and catch2 ...
Thank you.

I suspect this has to do with how homebrew has put things into /opt/homebrew on apple silicone macs.

Just tried installing from your tap and got this error log:

I'm on macOS 13.2.1, M1 Pro.

Hmm yeah, I think I need to change something in the recipe to get it to search for the library files in the homebrew folder. I'm definitely doing something wrong.

[evanpurkhiser]

I had a few people test it out, wondering if newer brew may have fixed this?

Could any of you let me know if this is still happening?

[sleeplessKomodo]

experiencing this error on fedora, as ffmpeg-libs conflicts with libavutil-devel.

I just tried it now, your tap worked for me @evanpurkhiser

Solution from @floydback also worked for me.
