On linux or Windows or other?

If something like linux have a look at the first post here

For extracting cover art you could try something like

wvunpack -xx "Cover Art (Front)=file.jpg" -v test.wv

which in this case would extract the cover art and put in a file called file.jpg

Ok, here' the issue:

MP3Tag is showing ONE front cover and ONE back cover, duplicated, so it shows as 4 embedded files.
But foobar2000 is actually showing ONE front, ONE back and the ONE disc image, totalizing 3 images.
What I wanted is to extract each one of them and I can't get this done, is there a way to list the tag fields to know their names?

wvunpack -ss test.wv

lists all the tags

-ss actually display the stream information... it doesn't return tags (although help says 'including tags'). The tags here are APEv2.

It certainly does for me on Windows

Something's wrong on my side...

edit:  it's a full image, no embedded cuesheet, and MP3Tag says it is APEv2 - and it shows the tags... weirdest thing.

If the total size of the APEv2 tag is over 1MB, then WavPack will ignore it (I think...I'm away from home/code). If other programs are showing the tags and wvunpack is not, then that would be my first guess.

If the tags were created by another program, then perhaps WavPack is just more picky about the tags being correctly formatted.

edit: spelling/typo

Thanks bryant. Yes, The images go over 1MB easily, I can see that. That's why is not returning on command line.
What program is recommended besides MP3Tag to extract the binary tags

Ok, I just realized I have a .iso.wv file which is not a true wavpack file, but a ZIP file with the wavpack file and other files. Whoever made the file this way has plenty crap on his mind. I was curious about "iso.wv", that is why I got this file...
