我正在尝试使用OpenCV 2.4.0中的python 2.7.2创建视频。但是avi文件的大小为0。

我的代码:

from cv2 import *

im1 = cv.LoadImage("1.jpg")

fps = 20
frame_size = cv.GetSize(im1)

#writer = cv.CreateVideoWriter("out.avi", CV_FOURCC('M', 'J', 'P', 'G'), fps, frame_size, True)

v = VideoWriter()

v.open("out.avi", cv.CV_FOURCC('F', 'M', 'P', '4'), fps, (800,600), True)
print v.isOpened()
isOpened()始终返回false

另一种尝试:
#!/usr/bin/env python
import sys

from cv2 import *

im1 = cv.LoadImage("1.jpg")

if not im1:
    print "Error loading image"

im2 = cv.LoadImage("2.jpg")

if not im1:
    print "Error loading image"

fps = 20
frame_size = cv.GetSize(im1)

writer = cv.CreateVideoWriter("out.avi", cv.CV_FOURCC('M', 'J', 'P', 'G'), fps, frame_size, True)

if not writer:
    print "Error in creating video writer"
    sys.exit(1)
else:
    cv.WriteFrame(writer, im1)
    cv.WriteFrame(writer, im2)

del writer

没有错误,但输出为空。

我想念什么?

最佳答案

import cv2

img1 = cv2.imread('1.jpg')
img2 = cv2.imread('2.jpg')
img3 = cv2.imread('3.jpg')

height , width , layers =  img1.shape

video = cv2.VideoWriter('video.avi',-1,1,(width,height))

video.write(img1)
video.write(img2)
video.write(img3)

cv2.destroyAllWindows()
video.release()
