Actually I have a Jetson orin nano Developer kit and I have the Gstreamer(version:1.20.3) but I am not able to enable it with the opencv build even if I am enabling it in the build its not enabled after the build is complete
Hi,
Please install the OpenCV package(in SDK Components) through SDKManager. The default package has gstreamer be enabled. The latest release for Orin Nano is Jetpack 6.2.
can u provide me with the link of jetpack 6.2
You can execute the below command to install full jetpack on your unit.
Sudo apt-get install jetpack
You should have internet connection working on your unit
i have it already installed should i uninstall and reinstall this?
Hi,
Please replacev4l2src with videotestsrc is-live=1 in the sample:
V4l2src using OpenCV Gstreamer is not working in Jetson Xavier NX - #3 by DaneLLL
And give it a run. It should be run successfully if you use default OpenCV package.
This is the build information and here it indicates the gstreamer is not enabled even after enabling it during the build I want to enable it as I am using gstreamer pipeline
Hi,
If you use default OpenCV package, it should look like:
