I have a macbook w/Apple Silicon M2 Max running Sonoma 14.3.1.
I ran brew install ffmpeg last December 2023 and it installed and ran fine.
Two days ago I installed an unrelated package (poppler) and brew autoupdated ffmpeg to 7.0_1. I used ffmpeg today and it promptly exits with Killed: 9. The console crash log has this:

Termination Reason:    Namespace CODESIGNING, Code 2 Invalid Page

I ran codesign -vvv hoping I’d see a bad sig but it doesn’t look that way. Note also I did not have to manually sign anything (or invoke sudo codesign) when I first installed it with brew.

$ codesign -vvv /opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg
/opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg: valid on disk
/opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg: satisfies its Designated Requirement

So I tried to resign it anyway:

sudo codesign -v --force --deep --sign - /opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg
/opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg: replacing existing signature
/opt/homebrew/Cellar/ffmpeg/7.0_1/bin/ffmpeg: signed Mach-O thin (arm64) [ffmpeg-5555494469e4341a87b53884a2fd20c8bcdb3000]

Still getting EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid)).

I also upgraded postgres from 16.0 to 16.3 using brew and that put new postgres executables on the machine but no problem launching those. In the course of autoupdating, brew also installed python 3.12. I have python pinned to 3.10, but I can manually (no symlink to homebrew/bin) run the 3.12 binary and that works too.

Any ideas on how to remediate?
