The one working fine uses QWidget and QFrame for painting, but this
approach doesn't work in QML (I only get audio playback but no video)
so this one can't be used.

I also tried the QGLWidget, but the problem here will be that this
approach needs working openGL, which will not be the case on the
target device (no opengl support there, so port to Qt5 isn't possible
I will have a look at the page about QDeclarativePerformance, hope
that this will help a bit.

Thanks so far.

So long
