Just a note that you can still compile libmedia{player,log}service as 64
bit version by removing LOCAL_32_BIT_ONLY from
frameworks/av/media/libmediaplayerservice/Android.mk, and at least that
works for me for the compiling part. Device BSP may contain other
multimedia related proprietary blobs, and they might only be available for
arm32.media-hub-server should not use libmediaplayerservice.so directly nor indirectly. It's camera_service, which is a standalone daemon, that runs inside Android container needs libmediaplayerservice.so.
