Issues with raspberry pi camera on jetson nano in headless mode

[akashsivapalanspam]

When I tried running programs from this repository GitHub - JetsonHacksNano/CSI-Camera: Simple example of using a CSI-Camera (like the Raspberry Pi Version 2 camera) with the NVIDIA Jetson Developer Kit,
it works when I connect the jetson nano to a monitor but doesn’t work when I connect the jetson nano to my laptop via putty. This is output I get when I run face_detect.py.

I am using a raspberry pi camera V2.1. I have verified that it works when I connect it with a monitor setup but it only seems to have this error in the headless mode setup.

Did you test X11 forwarding?

Hi,
In the sample, it calls the function for creating a window for video display:

cv2.namedWindow(window_title, cv2.WINDOW_AUTOSIZE)

cv2.imshow(window_title, camera_images)

For headless mode, you would need to customize the sample to remove the function calls. May refer to this transcoding sample and try to save to a video file:
