• Hardware Platform: Jetson AGX Orin
• DeepStream Version: 6.3
• JetPack Version 5.1.2 (r35.4.1)
• TensorRT Version: 8.5.2-1+cuda11.4
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type: Bug

We’re trying to use the nvv4l2h264enc plugin to encode a test video source but it seems like there’s an issue with the driver.

• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)

run gst-launch-1.0 -v videotestsrc ! nvvidconv ! "video/x-raw(memory:NVMM)" ! nvv4l2h264enc ! fakesink; you should get the following output:

Setting pipeline to PAUSED ...

I’m also seeing the following getting spammed in dmesg:

Hi,
Please make sure you use AGX Orin. We have AGX Orin, Orin NX, Orin Nano modules and there is no hardware encoder in Orin Nano. So if you use Orin Nano, this is expected.

If you use AGX Orin, this is not expected and we would suggest re-flash the system image.

Hi,
This is on the AGX Orin.
