Bug 240409 - be warned that it may turn out harder than expected, I dunno who 
marked it as a junior job. ;)

I don't think MultiTrack would be necessary, see below.

Not needed, .m4b is just a different extension for the .m4a type and shares the 
same mime-type.

No, and it shouldn't be need.

Definitely. I think the best approach is already outlined on the bug in comment 
#4: https://bugs.kde.org/show_bug.cgi?id=240409#c4

The biggest problem seems to be reading the chapter offsets from the .m4b files, 
you may want to make some research how these are stored and how they can be 
read - Amarok uses TagLib exclusively for metadata extraction, so preferably 
TagLib-based solution could be found.

If you don't find a feasible solution to read the chapters after reasonable 
time invested, you may want to consider picking another junior-job that is 
actually "junior".
