How to pass video frame from OpenCV to Matplotlib?

Question

Python

There is an IP camera from which the RTSP stream is taken through the Python version of OpenCV:

camera = cv2.VideoCapture(rtsp_url)
ret, frame = camera.read()
cv2.imshow('frame', frame)

Further, this stream must be transferred frame by frame to the library for processing, for this, according to the documentation of the library, it is used.
img = matplotlib.image.imread(img_file)
Now, for this, an intermediate saving of the OpenCV temporary file to disk is used, followed by its reading by Matplotlib

status = cv2.imwrite('image.jpg', frame)
img_file = matplotlib.image.imread('image.jpg')

How can you pass a stream frame by frame for processing directly without saving it to disk?

In frame - the data is already in the right form
