Those properties you mention belong to some video sink types such as
ximagesink and xvimagesink. The right moment to set those properties is
listen to the "prepare-xwindow-id" message at the pipeline bus with sync
handler. You have good code examples at [1].

With playbin2 you can easily access the audio and video sink through the
"audio-sink" and "video-sink" GObject properties. You can list them with
"$ gst-inspect playbin2".
