AACS – Android Auto Protocol Emulation for Linux

My headunit doesn't support FLAC, and has a hard limit on the number of tracks that it can play for some reason. As a result, a Pi or other SBC with AACS could provide this functionality, which is better than the $300+ for an HDMI adapter (which doesn't work in my case anyway).
I just am trying to get the word out so that the community can help the dev take this project further.
