基于opencv-python实现视频集逐帧提取为图片格式

程序代码框架

video	# 文件夹,存放着视频集
frame	# 文件夹,保存逐帧提取出来的图片
src	# 文件夹
    video_to_frame.py	# 源程序

源程序代码

import os
import cv2

video_src_path = '../video/'
frame_des_path = '../frame/'

def video2frame(video_src_path, frame_des_path, interval=1):
    videos = os.listdir(video_src_path)

    for video in videos:
        video_name = video[:-4]     # video format including mov/mkv
        os.mkdir(frame_des_path+video_name)

        frame_save_path = frame_des_path+video_name+'/'
        video_cur_path = os.path.join(video_src_path, video)
        capture = cv2.VideoCapture(video_cur_path)

        success = False
        count = 0
        if capture.isOpened():
            success, frame = capture.read()
            print("Start decoding file %s..." % video)
            count += 1
        else:
            print("Open %s failure!" % video)

        while success:
            if count % interval == 0:
                print("Writing the number %d of frame to src file" % (count//interval))
                cv2.imwrite(frame_save_path+'%d.jpg' % (count//interval), frame)
            success, frame = capture.read()
            count += 1

        capture.release()
        print("Encoding file %s success!" % video)


if __name__ == '__main__':
    video2frame(video_src_path, frame_des_path, interval=3)
