视频切片（批量）Python

一个视频切片，代码如下：

import cv2

vc = cv2.VideoCapture(r'F:\1\1\2\20210520000302.avi')  # 读入文件地址
n = 1  
if vc.isOpened():  
    rval, frame = vc.read()
else:
    rval = False
timeF = 2  # 视频帧计数间隔，按需修改
i = 0
while rval:  
    rval, frame = vc.read()
    if (n % timeF == 0):  
        i += 1
        a=r'F:\1\1\1/20210520000302_01_{}.jpg'
        b=cv2.imwrite(a.format(str(i).rjust(2,'0')),frame)  # 存储地址
        print(a)
    n = n + 1
    cv2.waitKey(1)
vc.release()

多个视频切片：按照上面代码做的修改。

import cv2
import os
import shutil

root_path = 'F:\\20240822015-20240822025-110\\'
out_path=r'F:\0/'

files_0 = os.listdir(root_path )

for file_0 in files_0:
    b=file_0.split('.')
    a=root_path+file_0
    vc = cv2.VideoCapture(os.path.join('r
