Hi All,

I compiled the sources and getting the bellow error when launching the app. Can someone help with this issue ? I am using FLIR One Pro: Android (USB-C).

Aborted (core dumped)

I forgot to load kernel modules. Now it works but I can see strange IR image below. What could be wrong ? sudo modprobe v4l2loopback video_nr=1,2,3
