[onboard] camera Opencv

Autonomous Machines Jetson & Embedded Systems Jetson TX2

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.
