Implements
gst::ObjectExt, glib::object::ObjectExt
Creates a new Player instance that uses signal_dispatcher to dispatch
signals to some event loop system, or emits signals directly if NULL is
passed. See PlayerGMainContextSignalDispatcher::new.
Video is going to be rendered by video_renderer, or if None is provided
no special video set up will be done and some default handling will be
performed.

Enable or disable accurate seeking. When enabled, elements will try harder to seek as accurately as possible to the requested seek position. Generally it will be slower especially for formats that don't have any indexes or timestamp markers in the stream.
If accurate seeking is disabled, elements will seek as close as the request position without slowing down seeking too much.
Accurate seeking is disabled by default.

Returns
The currently set, platform specific window handle
Configure a subregion as a video target within the window set by
PlayerVideoOverlayVideoRenderer::set_window_handle. 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 overlaid to
a specific region of that window only. After setting the new rectangle one
should call PlayerVideoOverlayVideoRenderer::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.
