该篇博客介绍如何使用Python将视频文件夹中的视频转换为一系列图片，每张图片根据视频中的时间戳进行命名。通过cv2库读取帧并保存，适合批量处理视频文件的截图任务。

python 将文件夹视频转化为图片，并以时间命名。

import os
import cv2
import time

videos_src_path = r'为转换视频路径'
videos_save_path = r"图片保存位置"

videos = os.listdir(videos_src_path)
#videos = filter(lambda x: x.endswith('MP4'), videos)
i=0
for each_video in videos:
    print('Video Name :', each_video)
    # get the name of each video, and make the directory to save frames
    each_video_name, _ = each_video.split('.')
    os.mkdir(videos_save_path + '/' + each_video_name)

    each_video_save_full_path = os.path.join(videos_save_path, each_video_name) + '/'

    # get the full path of each video, which will open the video tp extract frames
    each_video_full_path = os.path.join(videos_src_path, each_video)

    cap = cv2.VideoCapture(each_video_full_path)
    frame_count = 1
    success = True
    while (success):
        success, frame = cap.read()
        cv2.waitKey(10)
        i=i+1
        if success == True:
            uuid_str = time.strftime("%Y-%m-%d-%H_%M_%S", time.localtime())#图片命名为当前时间
            uuid_str = str(uuid_str)
            uuid_str = uuid_str.replace(":", "-")#去掉python读取时间中的：，文件命名不能有：
            uuid_str = uuid_str.replace(" ", "")#去掉python读取时间中空格，文件命名不能空格：
            if i%20==0:
                cv2.imwrite(each_video_save_full_path +uuid_str+ "%06d.jpg" % frame_count, frame)

        frame_count = frame_count + 1
    print('Final frame:', frame_count)
