Indeed.  Thank you very much.

For the purposes of resizing the window where video gets rendered in 
order to get an unscaled 1:1 display, I suppose the right caps object to 
get is the one returned by gst_pad_get_negotiated_caps(), right?  And 
use gst_video_get_size() and use the width and height as the new size of 
the window.  Or does pixel aspect ratio play a role here?  (I did set 
"force-aspect-ratio" to true on the video sink.)
