import pyvirtualcam


with pyvirtualcam.Camera(width=1280, height=720, fps=20, backend="unitycapture") as cam:
    print(f"Using virtual camera: {cam.device}")
    frame = np.zeros((cam.height, cam.width, 3), np.uint8)  # RGB
    while True:
        h, s, v = (cam.frames_sent % 100) / 100, 1.0, 1.0
        r, g, b = colorsys.hsv_to_rgb(h, s, v)
        frame[:] = (r * 255, g * 255, b * 255)
        cam.send(frame)
        cam.sleep_until_next_frame()
