How to dump ALL metadata from a media file, including cover image title ? [closed]
9 avril, par UnidealI have an MP3 song :


# ffprobe -hide_banner -i filename.mp3
Input #0, mp3, from 'filename.mp3':
 Metadata:
 composer : Music Author
 title : Song Name
 artist : Singer
 encoder : Lavf61.7.100
 genre : Rock
 date : 2025
 Duration: 00:03:14.04, start: 0.023021, bitrate: 208 kb/s
 Stream #0:0: Audio: mp3 (mp3float), 48000 Hz, stereo, fltp, 192 kb/s
 Metadata:
 encoder : Lavc61.19
 Stream #0:1: Video: png, rgb24(pc, gbr/unknown/unknown), 600x600 [SAR 1:1 DAR 1:1], 90k tbr, 90k tbn (attached pic)
 Metadata:
 title : Cover
 comment : Cover (front)



The task is to save its metadata to a text file and restore from that file later. Both goals should be accomplished with ffmpeg.


The simpliest method is to run :


# ffmpeg -i filename.mp3 -f ffmetadata metadata.txt



After that,
metadata.txt
contains :

;FFMETADATA1
composer=Music Author
title=Song Name
artist=Singer
date=2025
genre=Rock
encoder=Lavf61.7.100



I got global metadata only, but stream-specific info (cover image title and comment in my case) are missing.


Google suggested a more complex form of the command above to extract all metadata fields without any exclusions :


# ffmpeg -y -i filename.mp3 -c copy -map_metadata 0 -map_metadata:s:v 0:s:v -map_metadata:s:a 0:s:a -f ffmetadata metadata.txt



But the output is exactly the same :


;FFMETADATA1
composer=Music Author
title=Song Name
artist=Singer
date=2025
genre=Rock
encoder=Lavf61.7.100



Again, no info about the attached image.


Please explain what am I doing wrong.

FFMPEG convert videos using Automator [closed]
8 janvier, par FilipProI'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


- 

-
Run AppleScript


- 

- 

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







- 

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


- 

- 

sudo -S id -u







- 

-
Ask for Finder elements


- 

- Select folder, starting from "Downloads" folder, no multiple selection




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


- 

- 

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) :
