使用python和opencv保存视频时出错 [英] Error During Saving a video using python and opencv
本文介绍了使用python和opencv保存视频时出错的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是从网络摄像头保存视频的代码
This is the code to save video from the web cam
import numpy
import cv2
cap = cv2.VideoCapture(0)
# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (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
cap.release()
out.release()
cv2.destroyAllWindows()
当我在python中运行它时,会出现以下错误
When I Run It In python it gives the following error
> raceback (most recent call last): File
> "C:\Users\Prakash\Desktop\Image Proccessing\c.py", line 6, in <module>
> fourcc = cv2.VideoWriter_fourcc(*'XVID') AttributeError: 'module'
> object has no attribute 'VideoWriter_fourcc'
请帮助我解决此错误
推荐答案
Python/OpenCV 2.4.9不支持cv2.VideoWriter_fourcc,即3.x版本.如果您使用的是2.4.x:
Python / OpenCV 2.4.9 doesn't support cv2.VideoWriter_fourcc, which is version 3.x. If you're using 2.4.x:
替换
fourcc = cv2.VideoWriter_fourcc(*'XVID')
与
fourcc = cv2.cv.CV_FOURCC(*'XVID')
此处的好例子如何使用OpenCV和Python录制视频 转载供参考:
Good example here How to Record Video Using OpenCV and Python Reproduced for reference:
#!/usr/bin/env python
import cv2
if __name__ == "__main__":
# find the webcam
capture = cv2.VideoCapture(0)
# video recorder
fourcc = cv2.cv.CV_FOURCC(*'XVID') # cv2.VideoWriter_fourcc() does not exist
videoOut = cv2.VideoWriter("output.avi", fourcc, 20.0, (640, 480))
# record video
while (capture.isOpened()):
ret, frame = capture.read()
if ret:
videoOut.write(frame)
cv2.imshow('Video Stream', frame)
else:
break
# Tiny Pause
key = cv2.waitKey(1)
capture.release()
videoOut.release()
cv2.destroyAllWindows()
