#82 doesn't recognise mp3: "Skipped -2 zeroes at start of file"

[Benjamin Low]

Hello,

I've found that mpgtx doesn't recognise a number of mp3 files,
reporting:

$ mpgtx -vmpgtx Version 1.3.1
Copyleft 2001 Laurent Alacoque <laureck@users.sourceforge.net>
Partial work 2002 by Philipp Biermann <mpegcut@biermann.org>
updates, bugs, patch, money : http://mpgtx.sourceforge.net

$ mpginfo '/media/iTunes/iTunes Music/path/to/file.mp3'
Skipped -2 zeroes at start of file
mpgtx: AT EOF - please stop me!
mmm, this file does not start with a pack, offset: -2
use the desperate_mode switch as the first option -X to search for a
header in the whole file!
if you want to force the operation. May yield to an endless loop if no
valid header is found!
Does not even begin with a 00 00 01 xx sequence!

No success at all.
/media/iTunes/iTunes Music/path/to/file.mp3 is a Wave file
/media/iTunes/iTunes Music/path/to/file.mp3 is not a valid mpeg file

Trying -X indeed yields an endless loop.

mpgtx has similar troubles with a number of, but not all, my mp3 files.
These files all play fine, and are recognised by e.g. mp3info.

Am happy to provide sample files, if required.

Rgds,
Ben

in fact i am glad of this fussyness, as mpgtx helped me
identify 1200 mp3s in 66 directories that werent quite up
to scratch. I used
lame --resample 22050 filename.mp3
on all the files, and now they pass through mpgtx ok!
I was having issues concatenating them and with other
operations, and wondered why precisely because my other
players played them without moaning. It was only after I
tried mpgtx that the problem became apparent and things
got fixed.
