python 视频逐帧保存为图片

import cv2
import os

        file_name = video_name.split(‘.‘)[0]
        folder_name = video_path + file_name
        os.makedirs(folder_name,exist_ok=True)
        vc = cv2.VideoCapture(video_path+video_name) #读入视频文件

        rval=vc.isOpened()

        while rval:   #循环读取视频帧
            c = c + 1
            rval, frame = vc.read()
