我的代码出了什么问题？“AttributeError”模块“对象没有属性”“VideoWriter fourcc”

Question

我是郑元根。我有一个严肃的问题要问你。在像这样编码时，我会看到这样的警告消息。

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. 

我只是遵循"http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_gui/py_video_display/py_video_display.html“中的代码，然后，它就不能很好地工作了。如何更改此编码'fourcc = cv2.VideoWriter_fourcc('X'，'V'，'I'，‘D’)？我如何操作这个程序？

您要查找的函数不是cv2.VideoWriter.fourcc，而是cv2.VideoWriter_fourcc
