QtGstreamer build under Windows

oops, sorry. My reference was mostly to QML integration, and that is where
QtGStreamer is very outdated / hardly usable. I am not sure how good it is w/r
to Qt Widgets.
Of course you need a GStreamer binding, and QtGStreamer is just that. However,
it is not well maintained, so be prepared for some quirks. When we did our
stuff, we pulled together ideas from QtGStreamer and from the source code of the
new QtMultimedia (Qt 5.4) implementation, which on Linux platforms is
GStreamer-based
