This shooting command will display a preview serial port for about 5 seconds, and then shoot a full-pixel JPEG image and save it as test.jpg. Users can set the preview time through the -t parameter and can set the resolution of the captured image through --width and --height. E.g....

The settings of the preview serial port will not affect the resolution and aspect ratio of the camera image preview. The demo will scale the preview image to display in the preview window and adapt it according to the original image aspect ratio. Example: libcamera-hello -p 100,100,500,...
