• FFMPEG convert videos using Automator [closed]

  8 janvier, par FilipPro

  I'm trying to use Apple Automator (v2.10, Sonoma 14.7.1, Apple M1) to select a folder and convert all MP4 files to WMV files using FFMPEG. The user is supposed to export files from Final Cut Pro in MP4, put them in a folder of their choice and then start the automation by having to select the folder where MP4 files are saved.

  


  FFMPEG is installed via Homebrew and the installation folder was found via "which ffmpeg" ( /opt/homebrew/bin/ffmpeg ).

  


  This is the worklow I currently have : Full Automator Workflow

  


  


  1. Run AppleScript

     


     

     1. 


        on run {input, parameters}

  tell application "System Events"
    activate
    return text returned of (display dialog "Enter administrator password" default answer "" with hidden answer)
  end tell

  return input
end run


        


     


     


  


  2. Run Shell script (/bin/zsh, no input required)

     


     

     1. 


        sudo -S id -u


        


     


     


  


  3. Ask for Finder elements

     


     

     1. Select folder, starting from "Downloads" folder, no multiple selection

     


     


  


  4. Run Shell script (/bin/zsh, input as arguments)

     


     

     1. 


        cd "$1"

for f in *.mp4; do
  osascript -e "display notification \"Converting file: $f \" with title \"Video Conversion\""
  sudo /opt/homebrew/bin/ffmpeg -i "$f" -c:v wmv2 -b:v 3000k -c:a wmav2 -b:c 192k "${f%.*}.wmv"
  if [ $? -eq 0 ]; then
      osascript -e "display notification \"Converted file: $f \" with title \"Video Conversion\""
  else
      osascript -e "display notification \"Error converting file: $f \" with title \"Video Conversion\""
  fi
done


        


     


     


  


  


  The actual script (step 4) works perfectly if handtyped in Terminal but FFMPEG return "Error opening output files : Invalid argument" when run within the Automator workflow.

  


  This is the output of step 4 (I added *REDACTED FOR PRIVACY* instead of actual filenames) :
