FFmpeg封装MP4批处理
简要说明关键参数
-map 0:v:0 选择第0个输入的视频轨道的第0轨
-map 1:v:0 选择第1个输入的视频轨道的第0轨
-map 1:v:1 选择第1个输入的视频轨道的第1轨
-map 0 选择第1个输入的全部轨道
-map 0:a 选择第1个输入的全部音频轨道
-movflags +faststart 为在线播放提供可能
常用轨道：
v 视频
a 音频
s 字幕
ffmpeg会按照你的-map顺序来混流::for循环中的参数分别是起始序号、步长、终止序号，左闭右闭
for /l %%i in (1,1,10) do (
echo %%i.mp4
)
输出结果 为1.mp4 2.mp4 3.mp4 ... 10.mp4其实命令大同小异，按需修改即可。下面是我常用的几种情况：
直接封装
@echo off
for /l %%i in (1,1,62) do (
"C:\ffmpeg_win64.exe" -y -i "%%i.mp4" -i "C:\Posters\九州缥缈录.jpg" -map 0 -map 1 -c:v copy -c:a copy -c:v:1 copy -disposition:v:1 attached_pic -metadata encoding_tool="MP4 Tags Editor @ nilaoda" -metadata title="九州缥缈录(2019)" -metadata copyright="" -metadata comment="" -movflags +faststart -metadata:s:a:0 language=chi -metadata:s:a:0 handler_name="" -y MUX_%%i.mp4 && del "%%i.mp4"
)
pause音视频分离
@echo off
for /l %%i in (1,1,62) do (
"C:\ffmpeg_win64.exe" -y -i "%%iv.mp4" -i "%%ia.mp4" -i "C:\异常生物见闻录.jpg" -map 0 -map 1 -map 2 -c:v copy -c:a copy -c:v:1 copy -disposition:v:1 attached_pic -metadata encoding_tool="MP4 Tags Editor @ nilaoda" -metadata title="异常生物见闻录(2019)" -metadata copyright="" -metadata comment="" -movflags +faststart -metadata:s:a:0 language=chi -metadata:s:a:0 handler_name="" -y MUX_%%i.mp4 && del "%%i.mp4"
)
pause封装插入外部DDP音轨
@echo off

)
pause封装外部简体字幕
@echo off

)
pause封装外部简繁字幕
@echo off
for /l %%i in (1,1,52) do (
"C:\ffmpeg_win64.exe" -y -i "%%i.mp4" -i "C:\Posters\哦我的皇帝陛下.jpg" -i "简体\%%i.srt" -i "繁体\%%i.srt" -map 0 -map 1 -map 2 -map 3 -c:s mov_text -c:v copy -c:a copy -c:v:1 copy -disposition:v:1 attached_pic -metadata:s:s:0 handler_name="简中" -metadata:s:s:0 language=chi -metadata:s:s:1 handler_name="繁中" -metadata:s:s:1 language=chi -metadata encoding_tool="MP4 Tags Editor @ nilaoda" -metadata title="哦！我的皇帝陛下(2018)" -metadata copyright="" -metadata comment="" -movflags +faststart -y -bsf:a aac_adtstoasc MUX_%%i.mp4
