Camerata

A library for querying and capturing from cameras, based on nokhwa crate.

Examples

Query available cameras:

print(*camerata.query(), sep='\n')

Example output:

CameraInfo(index=2, name='UVC Camera (046d:0809)', description='Video4Linux Device @ /dev/video2', misc='')
CameraInfo(index=0, name='USB2.0 VGA UVC WebCam: USB2.0 V', description='Video4Linux Device @ /dev/video0', misc='')

Save an image (note: requires pillow to be installed):

import camerata
import time
cam = camerata.Camera(camerata.query()[0]) # Open a camera
while cam.poll_frame_pil() is None: # Note that .poll_frame_* functions never blocks
    time.sleep(0.1) # Wait until we get at least one frame from the camera
#time.sleep(1) # You might want to wait a bit longer while camera is calibrating
img = cam.poll_frame_pil()
img.save("img.png")
