NVENC is not working in jetson orin nano

NVIDIA Tegra Orin (nvgpu)/integrated
Jetpack 5.1.1
CUDA 11.4
VPI: 2.2.6

I’m encountering an issue with my Jetson Orin Nano board where the video encoding is not functioning correctly both inside and outside of the container. I’m receiving the following error message when attempting to run a video encoding pipeline

gst-launch-1.0 -v videotestsrc pattern=18 ! "video/x-raw,width=(int)1280, height=(int)720, framerate=20/1" ! videoscale ! nvvidconv ! nvv4l2h264enc ! rtph264pay config-interval=1 pt=96 ! udpsink host= port=5000 sync=false
Setting pipeline to PAUSED ...

I would greatly appreciate any assistance or suggestions on how to resolve this issue. Thank you in advance for your help!

On the first try, It hangs for some seconds/reboots itself.

Orin Nano has no HW encoder, so this is expected.
You may use SW encoder : How to record a video in orin nano since there ie no encoder present in it - #2 by Honey_Patouceul.
