Extracting image from video at a given time using OpenCV

Question

My task is to make a utility that can take a video and time in seconds.

The utility should write out jpeg images from the video with the given input.

E.g. let th

Answer 1

# Import the necessary packages
import cv2

vidcap = cv2.VideoCapture('Wildlife.mp4')
success,image = vidcap.read()
print success
#cv2.imwrite("frame.jpg", image) 

count = 0
framerate = vidcap.get(5)
print "framerate:", framerate
framecount = vidcap.get(7)
print "framecount:", framecount
vidcap.set(5,1)
newframerate = vidcap.get(5)
print "newframerate:", newframerate  

while success:
  success,image = vidcap.read()
  #cv2.imwrite("frame%d.jpg" % count, image) 

  getvalue = vidcap.get(0)
  print getvalue
  if getvalue == 20000:
    cv2.imwrite("frame%d.jpg" % getvalue, image)  

  #if cv2.waitKey(10) == 27:                     
      #break
  count += 1

The output is as follows

framerate: 29.97002997
framecount: 901.0
newframerate: 29.97002997

Why frame rate is not changing.I want to change frame rate to 1 so that whatever time value user gives i should be able to get image frame.
