Does OpenCV Have Gstreamer Support?

I am running Jetpack 4.3 on the AGX Xavier. I installed via the SDK manager and added all the software packages. I found on a forum that the built in version of OpenCV does not support Gstreamer in Jetpack 4.1. Is that still true for later Jetpack versions? Is there a way to check? I am considering following these instructions: but am unsure if it is necessary as it is for Jetpack 4.1.

We have gstreamer + OpenCV samples in source code package:
Please download it and try.

Do there have gstreamer + OpenCV samples in C?

Searching this forum, you may find many examples for different use cases on various releases.

Hi @chemistry0421
You should also see C samples in source code package:

If you use v4l2src plugin, may refer to this sample:

(Re-installing OpenCV is not required for later r32 releases)
