I need to compare 2 videos and check whether they are the same. I have a ref video to which the captured video has to be compared. How can I do this using OpenCV , numpy and matplotlib?

What do you count as "the same"? Pixelwise equality? In this case cv::sum(cv::absdiff(current_image,reference_image)) == 0 is the test you want to run. (Or something faster that fails faster if the images are not the same)

Actually my aim is to find whether a video has any artifacts. So I have a ref video which has no artifacts and I'm comparing the captured video with the ref video. Is there an option to do so in python Opencv?
