import cv2 
import numpy as np
cap = cv2.VideoCapture('1.MP4')
fourcc = cv2.FOURCC(*'XVID')
out  = cv2.videoWriter('output.avi',fourcc,20.0,(640,480))

while (1):
  #Capture frame-by-frame
  #ret = cap.set(3,960),cap.set(4,720)
  ret, frame = cap.read()
  if ret == True:
      frame = cv2.flip(frame,0)
      out.write(frame)

      cv2.imshow('frame',frame)

      if cv2.waitKey(1) == ord('q'):
          break
  else:
      break

cap.release()
out.release()
cv2.destroyAllWindows()

如上所示，这是opencv文档中的demo，在我的电脑上可以运行。像这样的回溯：

Traceback (most recent call last):
  File "E:\opencv\Pic\test.py", line 34, in <module>
    fourcc = cv2.cv.FOURCC(*'XVID')
AttributeError: module 'cv2.cv2' has no attribute 'cv'

我还看到了一些解决方案，例如将 cv2.cv 更改为 cv2 ，而回溯如下：
