@aarkay14 i've checked yesterday.
kodi doesnt seem to use libaacs (i've grepped the source code and dependancies),
so i don't think that adding this lib will make bluerays work on batocera.
i guess it requires vlc or an other program too.
So, for the moment, i don't think to add this lib in batocera.
Perhaps we should try to understand if/how kodi is supposed to read blueray. however, it seems that kodi requires an external player. i won't make think complicated.
