How to install Opencv 4.0 on Jetson TX2 with jetpack 4.2

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Please note that opencv4.0 is not NVIDIA release, so it should have nothing to do with jetpack version.

Hi

I succesfully installed OpenCV with this script.

But now I’m not able to run cv2.Videocapture anymore…

I got an error like this:

[ WARN:0] global /home/ivanflurina/JEP/script/opencv-4.1.1/modules/videoio/src/cap_gstreamer.cpp (933) open OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1

Don’t know whats’s wrong with gstreamer now… It worked fine with OpenCV 3.1.0 from Jetpack 4.2…

I have a similar problem. What can be the solutions?

Or maybe you know a possibility to add the opencv-contrib modules to the installed openCV version 3.3.1 from jetpack 4.2?

I tried installing opencv on Jetson TX2 using quoted script.

I have encountered below errors.

Jetson TX2 OS ubuntu 18.04

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.3 LTS
Release:        18.04
Codename:       bionic

Any leads to resolve above errors?
or Alternate way to install opencv (version: 4.0+) on Jetson TX2 will be great?

Thank you.
