I think the raspberry version uses gstreamer and AFAIK there is one fully functional fork. Look for gartnera fork on Github.Did anyone manage to start Headunit on Raspberry Pi?
I was able to compile different versions but all ended up with errors when connecting and starting AA.
I guess it's possible to start Headunit on the Pi but there are many things to fix.
E.g. opengl problems. The Pi only has experimental gl drivers. That caused several errors on my way.
Maybe someone else did some investigation ?
