x86_64结构，需要用intel版本的homebrew，编译环境也要是x86_64

arch -x86_64 zsh -c 'cd /Users/jack/ffmpeg-8.0make distcleanexport PATH="/usr/local/bin:$PATH"export CC="clang"export CXX="clang++"export CFLAGS="-arch x86_64"export LDFLAGS="-arch x86_64"export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
./configure --extra-cflags="-mmacosx-version-min=10.13" --extra-ldflags="-mmacosx-version-min=10.13" --arch=x86_64 --disable-shared --enable-static --prefix=$(pwd)/build_x86_64make -j"$(sysctl -n hw.ncpu)"make install
