Cannot identify device '/dev/v4l2-nvenc' on Orin NX

[gramadon]

I am using Boson carrier board for Framos (https://connecttech.com/product/boson-for-framos-carrier-board-for-nvidia-jetson-orin-nx/), and Framos IMX304C sensor along with Orin NX to encode the camera stream via gstreamer. I am using JetPack 5.1.1 and CTI-L4T-ORIN-NX-NANO-35.3.1-V004.tgz on my Orin NX. When I am trying to encode the video stream using the hardware accelerator in my GStreamer pipeline it fails with the following error:

gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=1 '!' 'video/x-raw(memory:NVMM), framerate=30/1' '!' nvvidconv '!' videoconvert '!' nvv4l2h264enc '!' h264parse '!' qtmux '!' filesink location=/tmp/test.mp4 -e
Setting pipeline to PAUSED ...

Has anybody encountered a similar issue?

hello gramadon,

could you please revise your pipeline to remove video converter for testing,
for example, $ gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=1 '!' 'video/x-raw(memory:NVMM), framerate=30/1' '!' nvv4l2h264enc '!' h264parse '!' qtmux '!' filesink location=/tmp/test.mp4 -e

moreover,
let’s check your camera functionality.
you may running with below commands to disable preview and shows frame-rate only for verification.
for instance, $ gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1, format=NV12' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=I420' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

here’s an example to use software encode, (it’s for Orin Nano, since it does not have the NVENC engine)
you may see-also developer guide, Argus Camera Software Encode Sample for reference.

removing the vide converter from the pipeline did the trick, now the pipeline works. thanks!
