Thanks Martin. I use a precompiled binary of the latest snapshot build from https://evermeet.cx/ffmpeg. Apologies, I’m not familiar with how to test an individual patch, but I’m sure it involves compiling the source and although I’ve used brew install a few times, I’m very much a novice in that area. Has your patch not been committed to the project?
