• Continuously Scan Directory and Perform Script on New Items

  5 January 2021, by Jeff Weese

  First, please forgive me and be easy on me if this question seems easy; the first time I tried posting a question about another subject, I didn't provide enough information a few months ago. My apologies.

  


  I'm trying to scan my incoming media folder for new audio files and convert them to my preferred format into another folder, without removing the originals.

  


  I've written the script below and while it seems to work for one-offs, I can't seem to get it to create the destination directory name based off the source directory name; and I can't seem to figure out how to keep it looping, "scanning", for new media to arrive without processing what it's already processed.

  


  I hope this makes sense...

  


  #! /bin/bash

srcExt=$1
destExt=$2

srcDir=$3
destDir=$4

opts=$5

# Creating the directory name - not currently working
#   dirName="$(basename "$srcDir")"
#   mkdir "$destDir"/"$dirName"

for filename in "$srcDir"/*.flac; do

    basePath=${filename%.*}
    baseName=${basePath##*/}
    
    ffmpeg -i "$filename" $opts "$destDir"/"$baseName"."$destExt"

done

for filename in "$srcDir"/*.mp3; do

    basePath=${filename%.*} 
    baseName=${basePath##*/}

    ffmpeg -i "$filename" $opts "$destDir"/"$baseName"."$destExt"

done

• Recursive ffmpeg batch script within Windows

  30 September 2013, by 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?
