This plugin produces "pattern-count" squares in the bottom left corner of the video frames. The squares have a width and height of respectively "pattern-width" and "pattern-height". Even squares will be black and odd squares will be white.
After writing the pattern, "pattern-data-count" squares after the pattern squares are produced as the bitarray given in "pattern-data". 1 bits will produce white squares and 0 bits will produce black squares.
The element can be enabled with the "enabled" property. It is mostly used together with the GstVideoDetect plugin.
