python 图片合成视频

import cv2
import os


im_dir = '/home/moonx/apollo/data/lidar_on_image/'

video_dir = '/home/moonx/apollo/data/test.avi'
im_list = os.listdir(im_dir)
im_list=sorted(im_list)  #最好再看看图片顺序对不
fps = 10


img_size = (1920,1080) #图片分辨率

fourcc = cv2.cv.CV_FOURCC('M','J','P','G') #opencv版本是2
#fourcc = cv2.VideoWriter_fourcc(*'XVID') #opencv版本是3

videoWriter = cv2.VideoWriter(video_dir, fourcc, fps, img_size)

count = 1
for i in im_list:
    im_name = os.path.join(im_dir+i)
    frame = cv2.imread(im_name)
    videoWriter.write(frame)
    print im_name
    # count+=1
    # if (count == 100):
    #     break
videoWriter.release()
print 'finish'

忘记转谁的了。
