After each execution of the code, 150 MB of memory leaks out.
cam = cv2.VideoCapture('rtsp://admin:admin@192.168.0.64:554/Streaming/Channels/101')
ret_val, img = cam.read()
ret_val = cv2.imwrite(str(chat_id) + '.jpg',img)
cam.release()
cv2.destroyAllWindows()
Most likely this is due to OpenCV. Below is the configuration OpenCV. I'm using GStreamer, to work with the H264 stream from IP camera.
