Using CSI camera
CLI
Python
CLI
To capture video from the camera run the command
<code">gst-launch-1.0 rkisp device=/dev/video0 path-iqf=/etc/iqfiles/ov5647_default_default.xml ! videoconvert ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! x264enc ! flvmux ! filesink location=./test.flv
This will capture the camera output to a video file test.flv
Python
BrainyPi supports Picamera python library for capturing images from CSI camera.
CAUTION
Support for Picamera library is very limited. For now the library supports only capturing the images form CSI camera.
Program to capture the image from CSI camera
# Import required packages import picamera import time # Create PiCamera Object cam = picamera.PiCamera() # Capture the image of resolution 1920x1080 cam.resolution = (1920, 1080) # Flip image horizontally cam.hflip = True # Flip image vertically cam.vflip = True # Set the camera output rotation value which can be 0, 90, # 180 or 270. cam.rotation = 270 # Capture image and store it in .jpeg file cam.capture('image.jpeg')
Save the program in file picamera-capture.py
Run the program by running command
sudo python3 picamera-capture.py
