12 description: Overlay text or images onto the video
14 The watermark filter combines a frame producer and a composite transition to
15 overlay the specified text or image onto the video.
17 Supplying a filename with extension ".txt" causes the loader to load a pango
18 producer. Supplying a file name with an extension supported by gtk-pixbuf
19 causes the loader to load a pixbuf producer. See the pango and pixbuf
20 producers for details.
22 Note: If the filename begins with "+" the pango producer interprets the
23 filename as pango text.
