# 1.转换ts为mp4 #

## 第一步：官网下载 FFmpeg ##

打开[ https://ffmpeg.zeranoe.com/builds/][https_ffmpeg.zeranoe.com_builds]

点 download 按钮，找到自己的系统对应格式（如Windows7 64位下载压缩包ffmpeg-20200108-5bd0010-win64-static）

## 第二步：解压 ##

解压后，有个bin目录，里面是3个exe文件

## 第三步：编写批处理bat脚本，放在此路径下 ##

1、新建一个txt文本，将txt后缀修改为可执行的bat文件（如：run.bat）内容如下：

for %%a in ("D:\源视频目录\*.mp4") do ffmpeg -i "%%a"   -vcodec copy -acodec copy -f mpegts "D:\转换后目录\%%~na.ts"
    pause

2、点击保存

## 第四步：双击 run.bat 运行 ##

其它参考命令

for %%a in ("*.ts") do ffmpeg -i "%%a" -f mp4 -codec copy "%%~na.mp4
    pause

# 2.使用ffmpeg拆分大的mp4文件为小段的mp4文件 #

With ffmpeg you can split file using the following command:

**ffmpeg -acodec copy -vcodec copy -ss START -t LENGTH -i ORIGINALFILE.mp4 OUTFILE.mp4**

where START is starting positing in seconds or in format hh:mm:ss LENGTH is the chunk length in seconds or in format hh:mm:ss

So you will need to run this command few times depending on how long your video. If let's say your video is 31 minutes long and you want so split into 15 min chunks here is how you run it:

**ffmpeg -acodec copy -vcodec copy -ss 0 -t 00:15:00 -i ORIGINALFILE.mp4 OUTFILE-1.mp4**

**ffmpeg -acodec copy -vcodec copy -ss 00:15:00 -t 00:15:00 -i ORIGINALFILE.mp4 OUTFILE-2.mp4**

**ffmpeg -acodec copy -vcodec copy -ss 00:30:00 -t 00:15:00 -i ORIGINALFILE.mp4 OUTFILE-3.mp4**

There is a python script that you can use that does this automatically(i.e. takes video file, chunk size in seconds and generates individual playable video files): [http://icephoenix.us/notes-for-myself/auto-splitting-video-file-in-equal-chunks-with-ffmpeg-and-python/][http_icephoenix.us_notes-for-myself_auto-splitting-video-file-in-equal-chunks-with-ffmpeg-and-python]

    )

    for %%i in (*.mp4) do (
        for /f "tokens=2-5delims=:., " %%a in ('ffmpeg -i "%%i" 2^>^&1 ^| find "Duration:"') do (
            set /a "t=(1%%a%%100*3600+1%%b%%100*60+1%%c%%100)*1000+1%%d0%%1000,t-=t2,ms=t%%1000,t/=1000"
            set /a h=t/3600,m=t%%3600/60,s=t%%60,h+=100,m+=100,s+=100,ms+=1000
            set "t=!h:~1!:!m:~1!:!s:~1!.!ms:~1!"
            ffmpeg -i "%%i" -ss !s1! -to !t! -vcodec copy -acodec copy "NEW\%%i" -y
        )
    )
    pause

#python+ffmpeg批量去视频开头
    import os
    pp=os.getcwd()
    path=''#视频所在目录
    time=''#格式为hh:mm:ss[.xxx]的形式
    for i in os.listdir(path):
        os.system("""ffmpeg -i '%s/%s/%s' -ss %s -vcodec copy -acodec copy '%s/%s/%s'&&rm '%s/%s/%s'"""%(pp,path,i,time,pp,path,i[:-4]+'@.mp4',pp,path,i))
    #将这个脚本放到视频的上一层目录，然后指定path为所在目录，time为截去的时间
    #视频切割由ffmpeg实现，并且会删除原文件
