around this issue This isn't the problem you're having (as far as I can tell) but it's important to note that this API has changed recently, now it expects a void pointer of data which allows you to pass in a handle to user_data (or NULL) when you connect your callback.
code :
gboolean drawCallback (GLuint texture, GLuint width, GLuint height, gpointer data)

should help you out I finally have a working solution for the following setup:

like below fixes the issue I recommend you install an interpreter with tab completion such as ipython to look up methods. You will find documentation for introspected libs in python at http://lazka.github.io/pgi-docs/
Regarding your specific problem, the call to make is Gst.ElementFactory.make ()

should help you out I found the reason, it's because QtCreator use the library located in /home/user/Qt/5.5/gcc_64/plugins/mediaservice/ but these libraries use the 0.10 version of gstreamer:
code :
qmake player.pro && make
