Why do not simply use QtGStreamer?

Off course the question arises: "Why do not simply use QtGStreamer?" Ya, actually this should be the way to do. Since redoing it by your self is often useless. The downside is: currently only gstreamer-0.10 is supported and on updates this will not change. And the installation on Windows is difficult.
In QtGstreamer there are principally two ways of integrating a video into a GUI:
1) QGst::Ui::GraphicsVideoWidget (in conjunction with QGst::Ui::GraphicsVideoSurface)
2) QGst::Ui::VideoWidget

Here is an example for option 1:

qtgraphicswidget.pro


main.cpp:



And here is an example for option 2:

main.cpp:


The project file can be the sane as for option 1
