ffmpeg の依存関係を再インストールしましたが、問題は解決しません。
問題を解決するためのアイデアや提案はありますか? どうもありがとうございました！
編集注：実行時にこれに気付きますbrew upgrade：
==> Upgrading ffmpeg
==> Installing ffmpeg dependency: libass
Error: libass dependency fontconfig was built with the following
C++ standard library: libstdc++ (from clang)
This is incompatible with the standard library being used
to build libass: libc++ (from clang)
Please reinstall fontconfig using a compatible compiler.
