Windows下合并音视频脚本

[ruin1990]

使用方法就是下载每次不都是xxx.mp4和xxx (1).mp4，把2个文件丢一起然后bat和ffmpeg.exe丢一起，xxx.mp4丢bat上就行了 下面内容保存为bat

@echo off
REM 读取第一个参数
SET param=%1
REM 不论param有没有双引号，都给其加上
SET param="%param%"
REM 将param中的所有双引号删除
SET param=%param:"=%
REM 给没有双引号的param加上双引号
rem SET param="%param%"

set filename=%param%
set filename=%filename:~0,-4%
set audio_file="%filename%.mp4"
set aac_file="%filename%.aac"
set video_file="%filename% (1).mp4"
set result_file="%filename%_merged.mp4"
echo %filename%
echo %audio_file%
echo %aac_file%
echo %video_file%

echo 1.export aac audio
rem 先把音频分离出来
rem ffmpeg -i "audio.m4a" -acodec copy "tmp_audio.aac"
ffmpeg -i %audio_file% -acodec copy %aac_file%
echo 2.merge aac and video
rem 然后把原始视频和上一步得到的aac组装到一起
rem ffmpeg -i "video.mp4" -i "tmp_audio.aac" -c copy -shortest "output.mp4"
ffmpeg -i %video_file% -i %aac_file% -c copy -shortest %result_file%
echo finish
pause

合并以后有可能会造成视频画面卡主不动的情况

经过测试 是视频文件有问题 提取的视频文件可能会有编码不对之类的问题 不论FFMPEG还是小丸均无法合并（FFMPEG合并后视频卡住） 解决方法是先把视频在小丸X264压一遍 音频用小丸提取出AAC 然后再去小丸合并 就可成功 参考资料：https://www.cnbeining.com/2017/10/1211/

看具体操作，把mp4文件丢到bat上。
