我的编码有什么问题？'AttributeError 'module' 对象没有属性 'VideoWriter fourcc

Question

我是Jeong Won Kyoung。我有个严肃的问题要问你。当像这样编码时，我有这样的警告消息。

编码:

#coding utf-8
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
#define the codec and create VideoWriter object
fourcc = cv2.VideoWriter.fourcc('X','V','I','D')
out = cv2.VideoWriter('output.avi',fource, 20, (640,480))
while(cap.isOpened()):
    ret, frame = cap.read()
    if ret==True:
        frame = cv2.flip(frame,0)
        #write the flipped frame
        out.write(frame)
        cv2.imshow('frame',frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break
    else:
        break
#release everything if job is finishing
cap.release()
out.release()
cv2.destroyAllWindows()
And then I ran the module, I got this weird result.
"Traceback (most recent call last)
File"/home/pi/saving_a_video.py", line.8,in <module>
     fourcc = cv2.VideoWriter_fourcc('X','V','I','D') 
AttributeError: 'module' object has no attribute 'VideoWriter fourcc"
has appeared on other python window. 

我只是从"http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_gui/py_video_display/py_video_display.html"然后，它就不起作用了。我怎么能改变这种编码'fourcc = cv2.VideoWriter_fourcc('X'，'V'，'I'，'D')'?我怎么操作这个程序?

您要查找的函数是cv2.VideoWriter_fourcc而不是cv2.VideoWriter.fourcc
