Analysis

The file contains two streams: a video container and an audio stream. The file’s well-formedness is declared ‘null’ but the validator has set a grading value of ‘fi-dpres-acceptable-file-format’ for the file which implies that even though the file si recognised, it can not be appraised neither as well-formed not not well-formed. This is a logical conflict and implies that there is a problem with the validating software because the acceptable grade should result in a decisive result for well-formedness.

Is it a bug in the validating software? - yes

Possible solutions

Remove album cover image from MP3 file

The suggestion

Migrate only audio streams from an MP3 file to remove an attached image and related video container stream.

Execution

ffmpeg -i <input file>.mp3 -c:a copy -map 0 <output file>.mp3

Tested with: FFmpeg 6.0

Effects

Image and videocontainer streams are stripped from the output file. Only (all) audio streams are migrated to the output file.

Justification

MP3 files contain primarily audio.

Migrated files
