Qt embedded 4.5.0 and phonon

[webquinty]

Hello,

I just compile Qt embedded with phonon support and musis and videos works fine, but videos keeps freezing.

My questions is, is it possible to use directFB??
I have read that DirectFB provides hardware graphics acceleration.

Best regards.

Hello,

I have downloaded Qt 4.6.2, and I have compiled with --qt-gfx-directfb, and DirectFB 1.1.1 without problems, but perfomce is the same than without directFB.

# ./analogclock -qws -display directfb
