I'm on a Mac OS X 10.7.3 System, using avidemux from homebrew v2.5.5 (r7908).
My music is tagged with MusicBranz Picard (http://musicbrainz.org/doc/MusicBrainz_Picard). Tagged with this application the mp3s won't load at all or is just silent. Stripping the mp3 with id3v2 and copying id3v1 to id3v2 works.
Here is a sample file that loads, but is silent: http://dl.dropbox.com/u/344000/avidemux_test_v1v2_original_nowork.mp3
I tried different settings in Picard and found out the following, with the "clear existing tags" checked:
- ID3v1 settings doesn't matter
- ID3v2 2.4 or ID3v2 2.3 doesn't matter
- Loads mp3s with UTF-16, but are silent
- Doesn't load mp3s with UTF-8 or ISO-8859-1 setting at all
I've using LAME 64bits version 3.99.4 from homebrew repository installed.
Not sure if it's a Picard issue, but I'd rather not re-tag all my mp3s.
There is one field in it labeled: Arrangeur with this content:
mix|Danton Supple|flugelhorn, saxophone and trumpet|Jamie Sefton|lead vocal|Amy Macdonald|electric guitar|Jolyon Dixon
This is causing issues. When this one is empty avidemux 2.6 accepts the .mp3. and still has ID3v1.1 and ID3v2.3.0
Could have something to do with | symbol or its length?. The mp3 itself is fine.
You could batch process copies of your mp3's needed in avidemux eventually with Kid3 - ID3 Tagger (//http://) <- click runs under Linux (KDE or only Qt), Windows and Mac OS X.
the modified mp3 can be found here: https://rapidshare.com/files/2190456063/avidemux_test_v1v2_original_modified.mp3
Just noticed a size difference of 0.3 MB between the two files. Is there cover art in it to? Could be another reason for the problem?
Tested in Ubuntu 12.04 64-bit with Avidemux v2.6.0 (r7934)
