I've been using MacPorts instead of Homebrew. It seems further ahead on the Darwin AArch64 transition. About 80% of things that I've tried have worked without trouble. Unfortunately, ffmpeg wasn't one of them. I got that working yesterday with libx264 and libx265 integration. Oddly, libx265 installs fine under MacPorts but libx264 doesn't. But I was able to download the latest from git and build it and copy it manually to /opt/local.
