Save grayscale video in OpenCV?

Question

I am trying to save a video as .avi format but i keep getting the error \"could not demultiplex stream\". I primarily want to save grayscale videos

Answer 1

There are 3 things to keep in mind when you are trying to write Grayscale image in video writer. 1. while reading the image,keep 0 followed by ','

image = cv2.imread("data/PCB.jpg",0)

2&3. While creating the video writer, declare shape in opposite way and keep 0 followed by ',' as we did in step 1

fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (image.shape[1],image.shape[0]),0)
