Play a video in reverse mode using Python OpenCv

The full form of OpenCv is Open Source Computer Vision, using this library we can perform different operations on images, videos.

Application areas of OpenCV

  • Facial recognition system
  • Motion tracking
  • Artificial neural network
  • Deep neural network
  • Video streaming etc.

For installing on Windows we can use this command line

pip install opencv-python

For Linux −

sudo apt-get install python-opencv

To complete our task we have to follow some steps −

Step 1: We import OpenCv library named cv2.
Step 2: Take a video as input data.
Step 3: First we break the video into a number of frames and store all these frames in a list.
Step 4: When we are getting all the frames then we shall apply iteration method.
Step 5: Here we apply iteration for reversing the list.
Step 6: Use the reverse() method for reversing the order of the frames in the list.

Example code

import cv2
# Grab the current frame.
my_check , vid =
# use counter variable for
# Counting frames
counter = 0
check = True
frame_list = []
while(check == True):
cv2.imwrite("frame%d.jpg" %counter , vid)
check , vid =
# increment the counter by 1
counter += 1
# looping in the List of frames.
for frame in frame_list:
# show the frame.
cv2.imshow("Frame" , frame)
if cv2.waitKey(25) and 0xFF == ord("q"):
   # close any open windows
   for frame in frame_list:
   cv2.imshow("Frame" , frame)
if cv2.waitKey(25) and 0xFF == ord("q"):
