If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.

you need to

1. install all the libraries requied for x264 including nasm checkout full list in ffmpeg compilation guide https://trac.ffmpeg.org/wiki/CompilationGuide/macOS:

brew install automake fdk-aac git lame libass libtool libvorbis libvpx \
opus sdl shtool texi2html theora wget x264 x265 xvid nasm

verify that pkg-config can resolve x264 by running:

pkg-config --libs x264
# -L/opt/homebrew/Cellar/x264/r3108/lib -lx264

2. You need to build it and in theory it should work but in practice it doesn't because of rust-ffmepg-sys not reading all the linker flags from the ffmpeg output file. I fixed it here https://github.com/zmwangx/rust-ffmpeg-sys/pull/88
