I was porting two cameras on Jetson Orin NANO and I have already enabled one camera on CAM1 by below command.
DISPLAY=:0 gst-launch-1.0 v4l2src device=/dev/video1 ! \
"video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080" ! \
videoconvert ! xvimagesink sync=false
However, I cannot enable the same camera on CAM0 and I got the error message:
$ DISPLAY=:0 gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=(string)UYVY, width=(int)1920, height=(int)1080" ! videoconvert ! xvimagesink sync=false

Pipeline is live and does not need PREROLL ...

I checked and compared the device tree for tegra-capture-vi and nvcsi:
Is there any wrong setting for them?
