在OpenCV中保存视频(Linux, Python)

Question

下面是一个适用于Windows (original)的示例:

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
fourcc = cv2.VideoWriter_fourcc(*'XDIV')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480))
while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    out.write(frame)
    cv2.imshow('frame',gray)
    if cv2.waitKey(0) & 0xFF == ord('q'):
        break
cap.release()
out.release()
cv2.destroyAllWindows()

在Linux程序提供:

AttributeError: 'module' object没有属性'VideoWriter_fourcc'

Answer 1

我没有尝试，但这应该工作:

fourcc = cv2.cv.CV_FOURCC(*'XVID')
