Re: [Gtkpod-devel] Issue with large amount of Album Artwork

[Martin A. <au...@re...>]

Hi,

today I received a report from an amaroK user with a similar problem.
For those who
understand, some excerpts from #amarok.de:

<darkbit> aumuell: passiert irgendwie erst wenn =C3=BCber 20gb auf dem ipod=
 sind
...
[21:03] <darkbit> aumuell: und wieder alle covers weg
[21:04] <darkbit> aumuell: die artworkdb ist 2MB gro=DF. vielleicht
gibts da ein limit?
[21:09] <darkbit> aumuell: die datei wird auch nicht gr=F6=DFer wenn ich
noch mehr drauf hau

The guy with the problem also has an ipod video. And he noticed that
adding covers to his songs works for a while. At one point in time it
stopped working, he had about 20 GB of music on his ipod then. Later
he tried to copy the same songs to the ipod, but in a different order.
He noted that his artworkdb is 2 MB in size and suspected some kind of
limit. The file was not growing anymore despite him still copying
songs.

However, he didn't mention any console messages that I would have
attributed to libgpod. Put given that the hardware and the artworkdb
size match quite closely, the two problems could be related.

For the moment I cannot provide any additional info as darkbit is offline n=
ow.

Martin
