Creating a video using OpenCV 2.4.0 in python

Question

I am trying to create a video using OpenCV 2.4.0 in python 2.7.2. But the avi file size is 0.

My code:

from cv         


        

Answer 1

Found this code, which works for me (generating colored noise):

writer = cv2.VideoWriter("output.avi", cv2.VideoWriter_fourcc(*"MJPG"), 30,(640,480))
for frame in range(1000):
    writer.write(np.random.randint(0, 255, (480,640,3)).astype('uint8'))
writer.release()

Answer 2

height, width, layers = img.shape
out = cv2.VideoWriter("output.avi", cv2.VideoWriter_fourcc(*"XVID"), 30,(width,height))
out.write(img)
out.release()

Answer 3

import cv2

img1 = cv2.imread('1.jpg')
img2 = cv2.imread('2.jpg')
img3 = cv2.imread('3.jpg')

height , width , layers =  img1.shape

video = cv2.VideoWriter('video.avi',-1,1,(width,height))

video.write(img1)
video.write(img2)
video.write(img3)

cv2.destroyAllWindows()
video.release()
