Enabling libfdk_aac in ffmpeg installed with Homebrew
Homebrew v2.0 dropped all of the extra options that are not explicitly enabled in each formulae. So the --with options no longer work if you use the core Homebrew formulae.
Instead you can use a third-party repository (or "tap") such as homebrew-ffmpeg. This tap was created in response to the removal of the options from the core formulae.
Enable it then install ffmpeg:
brew tap homebrew-ffmpeg/ffmpeg
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-fdk-aac
You can see a list of additional options with:
brew options homebrew-ffmpeg/ffmpeg/ffmpeg
It's recommended to install a recent build from the git master branch. You can do so with the --HEAD option:
brew install homebrew-ffmpeg/ffmpeg/ffmpeg --with-fdk-aac --HEAD
You could use MacPorts to install ffmpeg with +nonfree option.
In summary, you'll need to:
Install Xcode tools. Try
xcode-select --install, or check Apple's developer website.Install MacPorts using the right pkg file for your MacOs release, or use one of the other options shown in the MacPorts installation guide.
Install ffmpeg using MacPorts:
$ sudo port install ffmpeg +nonfree

That will install all of those. The libfdk-aac codec will be built optimised for your machine, as well as ffmpeg. All of that takes some time.
Result:
$ ffmpeg -codecs | grep libfdk
AAC (Advanced Audio Coding) (decoders: aac aac_fixed aac_at libfdk_aac ) (encoders: aac aac_at libfdk_aac )
To see full codec list and supported formats:
$ ffmpeg -codecs
$ ffmpeg -formats
The other option would be to compile it yourself and choose whatever options you want.
