Macports

Install and use the open source FFmpeg utility on macOS for high quality audio and video encoding and transcoding with support for x two AAC-LC encoders (aac & libfdk_aac) and one HE-AAC(v1/2) encoder (libfdk_aac).

YAY! Awesome, a HUGE amount of tools and libraries that I’ve gotten used to having at my fingertips can be had on my Mac’s thanks to macports
