* This element overlays the buffer time stamps of a video stream on

* using the properties of the #GstTextOverlay class. By default, the
* time stamp is displayed in the top left corner of the picture, with some

* gst-launch -v videotestsrc ! timeoverlay ! xvimagesink

* </para>
* <para>
* Here is another pipeline that displays the time stamps with some leading
* text in the bottom right corner of the video picture, with the background
* of the text being shaded in order to make it more legible on top of a
