VideoOverlay.setRenderRectangle

gstvideo video_overlay VideoOverlay

Configure a subregion as a video target within the window set by gstvideo.video_overlay.VideoOverlay.setWindowHandle. If this is not used or not supported the video will fill the area of the window set as the overlay to 100%. By specifying the rectangle, the video can be overlayed to a specific region of that window only. After setting the new rectangle one should call gstvideo.video_overlay.VideoOverlay.expose to force a redraw. To unset the region pass -1 for the width and height parameters.

This method is needed for non fullscreen video overlay in UI toolkits that do not support subwindows.
