[onboard] camera Opencv

[Andrey1984]

It seems that tx2 has opencv 2.4.13 onboard by default.

Have anyone tried to get the devboard camera functioning with opencv at tx2?
It seems that somehow a line should be used like that

cv::VideoCapture cap("nvcamerasrc ! 'video/x-raw(memory:NVMM), width=640, height=480, framerate=30/1, format=NV12' ! nvvidconv flip-method=2 ! nvegltransform ! nveglglessink -e");

Hi Andrey,

I got the TX2 and onboard camera working with opencv-3.2.0 (or 3.1.0) by building my own opencv library enabling gstreamer-1.0 support.
AFAIK, opencv4tegra doesn’t provides gstreamer-1.0 support.
