// portion of video frame used for display (in video samples)
imgx = video_rect.left()
imgy = video_rect.top()
imgw = video_rect.width()
imgh = video_rect.height()

// total dimensions of video window (in display pixels)
dispxoff = display_video_rect.left()
dispyoff = display_video_rect.top()
dispwoff = display_video_rect.width()
disphoff = display_video_rect.height()

// portion of window containing video (in display pixels)
dispx = display_visible_rect.left()
dispy = display_visible_rect.top()
dispw = display_visible_rect.width()
disph = display_visible_rect.height()
