Easy enough for you to try though; make a Brewfile of only one [new] entry and see what happens. :)

Unfortunately I think brew dropped the ability to specify your own options.

brew options ffmpeg returns absolutely nothing ☹️

@tjluoma Yep 😕 Homebrew/homebrew-core#31510

The ffmpeg formula from https://github.com/homebrew-ffmpeg/homebrew-ffmpeg offers options.
