Dear All, I’m new to Jetson Nano Development. I installed OpenCV successfully. I also have GStreamer installed. when I’m trying to preview my camera with GStream, it starts the camera on the /dev/video0 port. But when I try to fix the autofocus on my Arducam IMX219, it crashes and sends the following error:
nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)NV12, framerate=(fraction)60/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)1280, height=(int)720, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink
Error generated. /dvs/git/dirty/git-master_linux/multimedia/nvgstreamer/gst-nvarguscamera/gstnvarguscamerasrc.cpp, execute:645 No cameras available

cv2.error: OpenCV(4.5.2) /home/xxxx/opencv/modules/highgui/src/window.cpp:412: error: (-215:Assertion failed) size.width>0 && size.height>0 in function ‘imshow’
I did the following troubleshooting:
- Check CV2 version: 4.5.2
- Gstreamer Installed
- For setting the autofocus, I’m using the script: Nvidia_Jetson/Autofocus.py at master · ArduCAM/Nvidia_Jetson · GitHub
Any help will be appreciated.
