* @see_also: #GstTextRender, #GstTextOverlay, #GstTimeOverlay, #GstSubParse
*
* This plugin renders text on top of a video stream. This can be either
* static text or text from buffers received on the text sink pad, e.g.
* as produced by the subparse element. If the text sink pad is not linked,
* the text set via the "text" property will be rendered. If the text sink
* pad is linked, text will be rendered as it is received on that pad,
* honouring and matching the buffer timestamps of both input streams.
2011-03-04 12:52:01 +00:00
*
* The text can contain newline characters and text wrapping is enabled by
* default.
