小米监控都是分段Mp4格式，无法统一播放，查找可以通过python进行合并，具体方法如下：

1、 安装moviepy

2、python 脚本

from moviepy.editor import *
import os

L = []
for root,dirs,files in os.walk("c:\\2"):
　　x = files.sort()
　　print(x)
　　for file in files:
　　　　if os.path.splitext(file)[1] == '.mp4':
　　　　　　# print(file)
　　　　　　filePath = os.path.join(root,file)
　　　　　　print(filePath)
　　　　　　video = VideoFileClip(filePath)
　　　　　　L.append(video)
#
final_clip = concatenate_videoclips(L)
final_clip.to_videofile("./target.mp4", fps=24, remove_temp=False)

 

3、运行结果

c:\2\57M45S_1596009465.mp4
