apple ipod touch 1g on slackware shows garbled filenames for my music files

Paulo2 · 01-13-2015, 12:26 PM

bassmadrigal and schneidz, thanks for the clarification.
It seems that a simple solution like reading data from tag (or even from
an external database) is out of consideration.

schneidz · 01-13-2015, 01:17 PM

maybe. what does

Code:

strings file.mp3 | head && strings file.mp3 | tail

print out ?

This file doesn't have an id3v1 tag

It seems that head output is id3v2 and tail output is id3v1,
then tail output is 'title artist album year (comment maybe)'
There is no track number or genre fields.

But I don't know how to get the content, there is no separation

This is a good way to see tag content, but if the tag is present inside the
file then other program would be able to read it and output in a better way.

would like to know, how you figure out they different versioned outputs thats id3v1 and id3v2?

and another program you mean like gtkpod,banshee(thanks schmatzler) or any specific libraries you know say like puddletag (bassmadrigal suggested but it dint work...something along these lines yes would be even better...)

seems like there is exactly 31 spaces for each field (except for the 4 digit year). i would assume the track number is some binary (that strings cant pull -- probably is able to be viewed via hexedit).

what is by Exorcist Junior by the way ?

the tag info is in the file... i'm surprised id3info isnt capturing the data from the it00nz file ?

by Exorcist well....the song doesnt have it...striking me here when you asked....some meta-data of the file say like some guy added his nickname to it and then uploaded...while i downloaded that i got it too....

schneidz · 01-14-2015, 08:53 AM

Code:

sudo yum install id3lib

It's part of id3lib. You can get it via slackbuilds.org or grab Eric's precompiled package.

^ well... does it list the contents of the id3tag info as its supposed to (what did you run and what was the output/error) ?
if not, maybe apple is doing something naughty to it00nz mp3's to break compatibility with standard tools.

i dont see anything added there and my filenames remain the same as before.....

id3info is a command you would run on the file. It wouldn't change the output of the strings command. What happens if you run id3info /location/to/music_file.mp3?

Here's the output from mine:

Code:

jbhansen@craven-moorhead:~$ id3info "/share/music/My Music/30 Seconds to Mars/A Beautiful Lie/01 - Attack - 30 Seconds to Mars.mp3" 

*** Tag information for /share/music/My Music/30 Seconds to Mars/A Beautiful Lie/01 - Attack - 30 Seconds to Mars.mp3

=== TPE1 (Lead performer(s)/Soloist(s)): 30 Seconds to Mars
=== TALB (Album/Movie/Show title): A Beautiful Lie
=== TYER (Year): 2006
=== TRCK (Track number/Position in set): 1
