VideoOverlay.setRenderRectangle

bool setRenderRectangle(int x, int y, int width, int height)

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.

Parameters

`x`	the horizontal offset of the render area inside the window
`y`	the vertical offset of the render area inside the window
`width`	the width of the render area inside the window
`height`	the height of the render area inside the window

Returns

false if not supported by the sink.
