C++ (Cpp) GstXOverlayClass::set_window_handle Beispiele

Beispiel #1

/**
 * gst_x_overlay_set_window_handle:
 * @overlay: a #GstXOverlay to set the window on.
 * @handle: a handle referencing the window.
 *
 * This will call the video overlay's set_window_handle method. You
 * should use this method to tell to a XOverlay to display video output to a
 * specific window (e.g. an XWindow on X11). Passing 0 as the  @handle will
 * tell the overlay to stop using that window and create an internal one.
 *
 * Since: 0.10.31
