i\'m currently porting an application from Qt4(.8.4) to Qt5(.2.0).
I\'m nearly done with all the known changes like deprecated toAscii()-function, missing QtGui and so on. N
Anyway,try give empty QMediaContent() to setMedia instead of 0. It is working OK for me (but,I try it in linux)
In your small test project,you use mp3 -- I'm not sure if it's supported.
