Java MediaPlayer

[bruemmer]

Since last christmas I play around with RaspberryPi, a HifiBerry DAC+ Pro and a RPi 7" Touchscreen to build a Audio client solution similar to the old Squeezebox Touch.

Out of the box you can find solutions like Max2Play - M2P gives me all I want including support for HifiBerry and the Touchscreen. But this solution is not Upnp based, it is based on Squeezelite and the Logitech Media Server.

Is there a similar RPi solution based on Upnp so I can use MinimServer? Maybe Java Mediaplayer on a RPi could be a base for such a solution - but I want a solution with a user interface based on the RPi Touchscreen (no additional control points like apps on Tablets or Smartphones because I already have the Touchscreen).
Can a Mediaplayer solution be extended e.g. by a control point software on the RPi on top of Mediaplayer?
