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()
