  Package libavutil was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libavutil.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'libavutil' found

how can i install ffmpeg-sys-next v6.0.1 accurately？

pacman -Sy mingw-w64-x86_64-pkg-config mingw-w64-x86_64-gcc mingw-w64-x86_64-ffmpeg

then check and now we can found libavutil.pc

$ pkg-config --list-all | grep libavutil
libavutil                                   libavutil - FFmpeg utility library
$ find /mingw64/lib/pkgconfig -type f -name libavutil.pc
/mingw64/lib/pkgconfig/libavutil.pc
$ echo $PKG_CONFIG_PATH
/mingw64/lib/pkgconfig:/mingw64/share/pkgconfig

if not, install libavutil by source code and add in hand:

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:{your_pkgconfig_path}
