Hi @Enes_Ulutas
This is rather a Jetson Nano issue than OpenCV one. Here some steps that you can do to try and check what might be going wrong.
Check if the camera was succesfully probed during boot and check for errors:
dmesg | grep imx219
Then you can try to manually dequeueing buffers from it using v4l-utils package:
Check formats:
v4l2-ctl -d /dev/video0 --list-formats-ext
Try one:
v4l2-ctl -d /dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap
Let me know if you hit any error at that point.
