How to Install FFMPEG with _ALL_ the Options using Homebrew on macOS

I needed libtheora support in my macOS / OSX install of ffmpeg. I installed ffmpeg using Homebrew but needed to add theora support.

I found this handy recipe which gives me an ffmpeg that supports tons of options!

brew install ffmpeg $(brew options ffmpeg | grep -vE '\s' | grep -- '--with-' | tr '\n' ' ')

If you already have ffmpeg installed you can remove it or just change the above command to be brew reinstall ....
