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: https://www.jetsonhacks.com/2018/11/08/build-opencv-3-4-on-nvidia-jetson-agx-xavier-developer-kit/ but am unsure if it is necessary as it is for Jetpack 4.1.

Hi,
We have gstreamer + OpenCV samples in source code package:
https://developer.nvidia.com/embedded/dlc/r32-3-1_Release_v1.0/Sources/T186/public_sources.tbz2
Please download it and try.

Hello,
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:
https://developer.nvidia.com/embedded/l4t/r32_release_v5.1/r32_release_v5.1/sources/t186/public_sources.tbz2

If you use v4l2src plugin, may refer to this sample:
Sony camera module cannot be opened with OpenCV on Xavier - #5 by DaneLLL
(Re-installing OpenCV is not required for later r32 releases)
