Hi,
You mention ‘It looking good on display’. Please share the command for reference. Argus is for Bayer sensors using hardware ISP engine. Probably yours is not this case.

I display the camera with standard ubuntu Cheese or GTK+ UVC Viewer
I don’t have a working pipeline at the moment

Hi,
It looks like you should use v4l2src to launch it. Please take a look at
Jetson Nano FAQ
Q: I have a USB camera. How can I launch it on Jetson Nano?

gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=(string)UYVY, width=(int)2592, height=(int)1944" ! nvvidconv ! "video/x-raw(memory:NVMM), format=(string)I420, width=(int)1920,height=(int)1080" ! nvoverlaysink overlay-w=1920 overlay-h=1080 sync=false
