By default it won't, as that requires XCB ( and is the status quo at
the moment ). It's only other method of output, YUV isn't supported
either, due to QGraphicsView lacking support for overlays.

Therefore the only working manner is mapping a video output (sink) in
memory to a QPixmap then painting it through using QPainter x times
per second ( Where x is the numbers of fps ) note that this would
absolutely suck for performance. The only other way to workaround it
is to use alien QWidget's...
