«convert.bat»:
@cd/d "%~dp0" @echo off SET vpath=%CD% for /R "%CD%\" %%i IN (*.mov) do ( ffmpeg.exe -i "%vpath%\%%~ni.mov" -vcodec libx264 -acodec aac "%vpath%\%%~ni.mp4" )
Операции подстановки ссылок на переменные команды FOR также расширены.
Допускается применение следующих синтаксических конструкций:
ffmpeg.exe -i "video.flv" -vcodec libx264 -acodec aac "video.mp4"
ffmpeg.exe -i "video.mp4" -vcodec libx264 -acodec aac "video2.mp4"
ffmpeg.exe -i "master.mkv" -vcodec libx264 -acodec aac "master.mp4"
ffmpeg.exe -i video.mp4 -b:a 192K -vn music.mp3
ffmpeg.exe -i "video.flv" -vcodec libx264 -acodec aac "video.mp4"
ffmpeg.exe -i "video.mp4" -vcodec libx264 -acodec aac "video2.mp4"
ffmpeg.exe -i 1.mp4 -b:a 192K -vn 1.mp3
-c:v mpeg4
-vcodec mpeg4
ffmpeg.exe -i 1.mp4 -i 1.mp3 -c:v copy -map 0:v:0 -map 1:a:0 ../1.mp4
-c:v mpeg4
-vcodec mpeg4
ffmpeg.exe -i input.wav -vn -ar 44100 -ac 2 -b:a 192k output.mp3
Explanation of the used arguments in this example.
Note to see docs about bit-rate argument's differences. Because maybe that option is the most important one, as it decides the "quality" versus "output size" versus "old mp3-player compatibility".
ffmpeg.exe -i audio.ogg -acodec libmp3lame audio.mp3
Bash script.
for i in *.ogg; do ffmpeg -i "$i" -acodec libmp3lame "${i%.*}.mp3"; done
Example-1.
«list.txt»
file '/path/to/first.mp3' file '/path/to/second.mp3'
Command.
ffmpeg.exe -f concat -i list.txt -c copy out.mp3
Example-2.
ffmpeg.exe -i first.mp3 -i second.mp3 -filter_complex [0:a][1:a]concat=n=2:v=0:a=1 out.mp3
Example-3.
ffmpeg.exe -i 'concat:1.mp3|2.mp3|3.mp3' -c copy output.mp3
Example-4.
Bash.
for f in *.mp3; do echo "file '$f'" >> inputs.txt; done
And command.
ffmpeg.exe -f concat -i inputs.txt -c copy output.mp3
Command.
ffmpeg.exe -i opening.mkv -i episode.mkv -i ending.mkv \ -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] \ concat=n=3:v=1:a=1 [v] [a]" \ -map "[v]" -map "[a]" output.mkv
Demuxer
«mylist.txt»
file '/path/to/file1' file '/path/to/file2' file '/path/to/file3'
Command
ffmpeg.exe -f concat -i mylist.txt -c copy output.mp4
CMD
(echo file 'first file.mp4' & echo file 'second file.mp4' )>list.txt
ffmpeg.exe -safe 0 -f concat -i list.txt -c copy output.mp4
or
(for %i in (*.mp4) do @echo file '%i') > list.txt
ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4
Concat protocol
Use this method with formats that support file-level concatenation (MPEG-1, MPEG-2 PS, DV). Do not use with MP4.
ffmpeg.exe -i "concat:input1|input2" -codec copy output.mkv
ffmpeg.exe -i 1.mp4 -i 1.mp3 -c:v copy -map 0:v:0 -map 1:a:0 ../1.mp4
