[vlc-devel] Adding an alternative cache key for art

So it means that the same file from the same URL needs to be cached
different times for different items? What's the logic behind that?

Does it modify the input item to fill the arturl field?

Maybe the script could be run to fill the arturl field just once, when
the item is loaded into the playlist? Following that approach this looks
more like a problem of lifetime and storage of input items with added
information, relating to *cough* playlist management *cough* media
library *cough*
