• Recursive ffmpeg batch script within Windows

  30 septembre 2013, par Tisch

  Complete change to the question !

  I now have the following script :

  @echo off
  
  REM keep a counter for files converted
  
  set /A nfile=0
  
  REM do not copy empty folders or any files
  
  @echo Copying directory structure from %0 to %1 ...
  
  xcopy /T %1 %2
  
  REM walk directory structure and convert each file in quiet mode
  
  for /R %1 %%v in (*.mp4, *.aac, *.flv, *.m4a, *.mp3) do (
  
      echo converting "%%~nxv" ...
  
      ffmpeg -v quiet -i "%%v" -vcodec libx264 "%2\%%~nv-converted.mp4"
  
      set /A nfile+=1
  
  )
  
  echo Done! Converted %nfile% file(s)

  Taken from : http://mostlybuggy.wordpress.com/2012/09/25/windows-batch-file-how-to-copy-and-convert-folders-recursively-with-ffmpeg/

  The videos are converting as expected when I run the following command :

  convert ..\..\folder ..\..\converted\

  However, the converted files end up in "converted" and not in their respective sub-folders.

  Any ideas ?
