So I am beginning the journey of porting LV2 plugins to Android (for my app Amp Rack, among other things). LV2 is the successor to LADSPA, and there are quite a few (!) very high quality plugins coded using the LV2 specification.
The very first roadblock that I've faced is that lilv and it's associated official™ libraries use the Meson build system. However, Meson doesn't compile for Android. So, I have to find some other way to build lilv, or deal with lv2 plugins directly.
First I will try and make lilv build for Android, as that seems like the way to go for now.
