The standard way of achieving size changes of the video window is to
create your own window and then embed the GStreamer video into that via
the GstVideoOverlay interface. On top of that you can then implement an
IPC mechanism (like the Unix signals) for communication between your
applications to change the size of the video window, but this is outside
the scope of GStreamer.

If you however want to change the size of the video stream itself you
can use the videoscale element (or any other scaling element) and a
capsfilter to enforce a different video size.
