iTunes artwork
zoara
Just messing with Corripio...
Where is the artwork for music actually stored? Is it in the AAC file?
So if I have a thirteen track album then I increase the size of the
album by thirteen times the size of the image?
That seems like a lot.
What size artowrks do people usually download? I've been picking up
500x500 images which I can imagine, multimplied by several thousand
tracks, will take up a fair amount of space. That's also bigger than the
iPod screen (isn't it?) so is there any benefit at all to large
artworks?
I haven't even got a colour screen iPod, I'm just playing out of
curiousity (and maybe to play with things like Clutter). Hasn't been
much luck so far in finding my album covers, though.

Stuff from iTMS seems to be 600x600 on the whole, but the JPEGs are
pretty small so why worry?
The current free iTMS download is a 44K image in a 3MB file, which is
about 1% of the total file size.

Maybe you want to use it on something later. It is rather good on
coverflow.

What, corripio? I found it somewhat limited, inacurate and unstable. I
gave up after a short while. It only uses iTunes and amazon, so you are
ok if you have chart albums, otherwise not as much use. I found a well
known and often discussed russian music web site better for album art.

So MP3s have an artwork slot in their format too?

Well, I wouldn't if I knew how big they were; but I can't work out how
to find out how big they are.

Okay, that would be fine.

All sorts of metadata gets dumped in it. Didn't someone write a
virus/exploit that they put the header and took advantage of some
exploit in Quicktime? Something rings a bell.

I just used copied one of the graphics out (via the Artwork tab) into
Preview. Preview's Get Info revealed the file size. Crude, but probably
about right.
You could also walk through the atoms in the m4a file and figure out
how big the graphic ones are. A job for a bit of perl...

The Audio::M4P::QuickTime module from CPAN does exactly what's needed,
and confirms that 44K image size is accurate.
Cheers,

Tempted, I googled.
Found this:
http://search.cpan.org/~billh/Audio-M4P-0.33/lib/Audio/M4P/QuickTime.pm
Maybe... maybe another day then.

Hmmm. The *only* artwork I'd found is 360k [1]; that's the method I used
and the one that prompted the question. It's a PICT file according to
Get Info, so I presumed it was measuring things wrong (uncompressed
size?).
-zoara-
[1] further testing just showed how few albums Corripio can find (and
how often it crashes); nevertheless: 112k pict, 325k pict, 1MB pict,
2.6MB pict [2], three completely bizarre mismatches [3], two complete
failures and three crashes.
[2] I stopped here because it appeared to be getting worse; two and a
half fricking megabytes?

So, er, maybe I'm being naive here, but are these 'user-contributed'
images? Because they vary vastly in size any quality (I found a
fingerprint-covered scan in a sample of around four!).

Ah, my expectations were a little high. I thought even those had started

Okay, that psses both the "does it have my music on it" test, and the
"is the file size enormous" test. But how do you get the album art off
of it? Er, you don't do it... *manually* do you? *shudder*.

That's the one I tried. It relies on a number of other modules from CPAN.
> Maybe... maybe another day then.
Here's a little script:
---
#!/usr/bin/perl -w
use strict;
use Audio::M4P::QuickTime;
my $qt = Audio::M4P::QuickTime->new(file => shift);
my $artwork = $qt->GetCoverArt();
foreach my $pic (@{$artwork}) {
print "Artwork is ", length($pic), " bytes\n";
}
---
Run it with an m4a/m4p file as an argument, and it tells you how big
each bit of artwork is.

Chris

Depends where you get your audio files from I guess.

Well, yes, a little bit. I also imagine there is some artwork and some
albums that never made it to the left pondian side of the world.

Well, most of the art I got was from an applescript from somewhere. I
use them for some of the other stuff it didn't get automatically.

Eh? I don't get that - how does the source of my audio files affect the
quality of the images that Corripio finds?

I don't know, does it? They're both Merkin companies, so I don't know.
FWIW, I thought Amazon was half-decent with music...

I'd just like to say "git", here. Not only have I spent an age furtling
through that russian site and dropping the images into iTunes, I've also
(thanks to your mention of it) downloaded coverflow. It's... lovely. And
it picks up album covers automagically[1], which is nice.
-z-
[1] Not all of them, but a better success rate than corripio by far.

Coverflow is pretty good. Very well done and enables you to flip through
your albums, although it does make it much more obvious when something
is missing (or wrong).

No, I was using Corripio to add artwork. That was my first ever diddle into
the world of songs-with-artwork, since all my music is ripped from CD.

It would be nice if I could tell it *not* to automatically google, so I
could use it to see what stuff in my iTunes library was missing artwork
[1]. That, or if it synced with iTunes and added the artwork it found to
iTunes.

[1] Is there a way to list artwork-less songs in iTunes?

Thank you very much. Your business is mostly appreciated.

No. Corruptio has it though. Maybe you could get it with applescript.

If you have music in the iTunes library with the wrong artwork, how do
you / can you delete it or correct it?

Get info on the file, go to the Artwork tab, select the artwork and hit
delete.
Took me a while to figure it out, too.

If corripio can show me what does and doesn't have artwork, I'd be happy to
do it manually.

Thanks. Didn't get chance to fiddle last night but I'll have a play
tonight.
