jonathancast / mp3-tag Goto Github PK

Due to a bug (fixed in version 0.9701) when multiple edits were done on
the same file, several K of zero bytes may have been inserted between
the ID3v2 tag and the body of audio.  These bytes were not included in
the count of bytes of the tag.

To fix files with this unwanted padding, one can do the following:

  a) include the byte count of the padding into the tag size (quick);

  b) Remove the padding (will require rewriting of the file, so may take
     some time).

To do "a", enable the option 'id3v2_mergepadding' when you update tags.

To do "b" enable the option 'id3v2_shrink' when you update tags.  (With
method 'update_tag', you may want to specify the $force2 option; with mp3info2,
use -2 option).

Example:

  mp3info2 -C "~id3v2_shrink=1~id3v2_mergepadding=1" -u2 -R .
