sudo apt update sudo apt install gstreamer1.0-tools gstreamer1.0-plugins-bad

1.5.2 Wayland

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/gstreamer-1.0 gst-launch-1.0 v4l2src device=/dev/video-camera0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! waylandsink

1.5.3 X11

export DISPLAY=:0.0 gst-launch-1.0 v4l2src device=/dev/video-camera0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! xvimagesink

1.5.4 Command Line

gst-launch-1.0 v4l2src num-buffers=20 device=/dev/video-camera0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 !

2 Frequently Asked Questions and Debugging Methods

2.1 Green Image Display (No 3A)

• Check if the rkaiq_3A_server service is running in the background

2.2 No Image

• Check if the rkaiq package is installed

sudo dpkg -l | grep rkaiq

• Check if the camera device nodes exist

pi@NanoPC-T6-LTS:$ ls /dev/video-camera0 /dev/video-camera0 pi@NanoPC-T6-LTS:$ ls /dev/video-camera1 /dev/video-camera1

2.3 Cheese Application Error or No Image

Currently, only the Cheese application on Debian 11 is supported. For other systems, please use GStreamer for camera preview.
