The UI knows about the player, which in turn knows about the media
input.

The question is how you would like to present chapters to the users. Do
you just want forward/backward chapter skip buttons? Or also e.g. a
ComboBox that lets the user choose a chapter? Should the UI display
which chapter is currently active? I never saw video files with
chapters and have no idea how they are supposed to be used.

Switching chapters should work through the controller/notification
mechanism; then we can easily add support for LIRC remote controls and
Equalizer in addition to the GUI.

Admittedly, this part of the code is very ugly. It comes from a very
early version of Bino that did not yet have a GUI. I'm currently
restructuring this so that adding new features will be easier in the
future.
