iTunes artwork changing during playback

I just downloaded a couple of XLR8R podcasts (http://feeds.xlr8r.com/xlr8r) in iTunes in AAC format.

I quickly noticed that the artwork changes with the tracks in the mix during playback. Does anyone know how these are stored? I can only see one artwork for the AAC file in mp3tag, but if one could extract the points at which each artwork switches, it would be pretty easy to create a cuesheet for the mix.

Thanks!

Raph

With the MPEG-4 container you can set multiple images to come up at different markers.

I've seen only one example of this long ago.

Thanks. Any idea how these markers can be extracted?

you could try yamb/mp4box. mp4box is a command line tool and yamb is a graphical front end for it.

Thanks. I've taken a look at it, but I couldn't find anything that would do that...

By the way, do you know the conversion from the SRT frame numbering format to the 75 fps in the cuesheet format (the 3 digits after the coma)? It seems to range from 0 to 999. Does it look correct?

wikipedia to the rescue.

The time format used is hours:minutes:seconds,milliseconds. The decimal separator used is the comma, since the program was written in France.
