JavaCV in MRL on Juerg's Odroid XU4

FPS is between 20 and 60 :) It oscillates in this range... but i guess it's pretty good :)

How did you install it?


Still a NOOB, I try to get OpenCV running on a Raspi 3 and on a XU4.

Latest MyRobotLab installed following Ray Edgley blog entry, including the workaround from kwatters.

Result: MyRobotLab is running but a lot of Exceptions when starting openCV and openCV still doesnt't work.

My gues is two missing libraries. How do I fix this or how to install everything correct?

kind regards
