https://cloud.mail.ru/public/KAkQ/AwCYiaiuF in case you like to run resulting cingg distribution on Ubuntu 16 / cmake 3.5.1 (only x86_64 qemu vm tested) I dunno, because I seems to be only one termux user than may be patch 0001 can go in as it shouldn't affect normal or even termux dynamic compilation? Other patches go in order. I hope you get x265 update from earlier folder, so not repeated here. Put new (old) libaom tar.xz in thirdparty/src, make sure you do not have libaom-v3.8.0.tar.xz there, try to build and render small av1 file.
