import cv2
from pysimplendi import NDISender

# initialize sender
sender = NDISender("pysimplendi")
# transparent image [width, height, 4]
image = cv2.imread("examples/img/test-trans.png", cv2.IMREAD_UNCHANGED)

image2 = cv2.imread("examples/img/test.png")

sender.send(image)
sender.send(image2)

NDIReceiver

NDISender can receive np array([width, height, 3] or [width, height, 4])

import cv2
from pysimplendi import NDIReceiver

receiver = NDIReceiver()
source_list = receiver.getSourceList()


# 1. get current frame
frame = receiver.getCurrentFrame()

# or

# 2. add handler
# call when frame received
def handler(image):
    print(image.shape)

receiver.addHandler("test", handler)
