It was literally long story. Me and guys from this forum waited for about 2 month for openni2 for arm64 from orbbec developers=)
One more thing. openni2, compiled for arm32 worked at odroid c2, but with very low fps(whole story was here - libORBEC.so for the aarch64 architecture - #21 by qlkvg). So, I think, high performance of orbbec cameras with odroid c2 is result of amlogic s905 arm64 architecture, not cpu frequency.
