how to use pi camera in jetson nano

[MAKER-park]

(Question) Have you tried mjpg-streaming linkage when connecting with the camera connector provided in jetson nano? After installing the pi camera compatible with jetson nano, if you mix and use the mjpg-stream operation command and the command to operate the pi camera, the following error occurs. I'm posting this because I can't find any reference material to find out if the camera access is wrong in this way or not. jetsonpark@jetsonpark-desktop:~/Documents/mjpg-stream/tmp/mjpg-streamer/mjpg-streamer-experimental$ mjpg_streamer -o "output_http.so -w ./www" -i "

I'm not sure what you're trying to do with that command but the second half is a gstreamer command and not related to mjpg_streamer at all.

You could try input_uvc as it looks like there is a v4l2 device, though it looks like it might be RGB only so no idea if it would work. I don't have a Jetson board so cannot help any further.

Thank you so much for your reply. Through the method you provided, I checked the list of supported cameras. Are these lists not applicable to these codes?
