• 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) :

• ffprobe newer version detect audio codec incorrectly

  16 janvier, par alancc

  I find a strange problem.

  


  I have a test video with h264 video codec and aac audio codec. It is at https://drive.google.com/file/d/1YAyz5cO0kb9r0MgahCpISR4bZ_1_n8PL/view?usp=sharing

  


  I build a ffmpeg version by myself, its version is :

  


  ffprobe version 7.0.2 Copyright (c) 2007-2024 the FFmpeg developers
  built with gcc 14.1.0 (Rev3, Built by MSYS2 project)
  configuration: --enable-shared
  libavutil      59.  8.100 / 59.  8.100
  libavcodec     61.  3.100 / 61.  3.100
  libavformat    61.  1.100 / 61.  1.100
  libavdevice    61.  1.100 / 61.  1.100
  libavfilter    10.  1.100 / 10.  1.100
  libswscale      8.  1.100 /  8.  1.100
  libswresample   5.  1.100 /  5.  1.100


  


  I then use ffprobe to get its info :

  


  ffprobe -v quiet -print_format ini -show_streams -show_packets test_h264.mp4 > test_h264.ini


  


  Then I get an ini file which shows the audio codec as MP2 :

  


  [streams.stream.0]
index=0
codec_name=mp2
codec_long_name=MP2 (MPEG audio layer 2)
profile=unknown

  Another developer he uses his version of ffprobe :

  


  ffprobe version 2023-02-22-git-d5cc7acff1-full_build-www.gyan.dev Copyright (c) 2007-2023 the FFmpeg developers  


  


  Based on the year, my version(2024) should be newer than his(2023), but his version of ffprobe can get the audio codec properly :

  


  [streams.stream.1]
index=1
codec_name=aac
codec_long_name=AAC (Advanced Audio Coding)
profile=LC
codec_type=audio
codec_tag_string=mp4a

  Why ?

  


  I also tried a ffprobe version on ubuntu with the following version :

  It will detect the audio as aac properly, but with different parameters, for example, bit_rate is 111733(developer) but 110399(ubuntu). But this parameter comes from the same file so should be the same.
