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 ::patern-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 videodetect plugin.
gst-launch videotestsrc ! videomark ! ximagesink
Add the default black/white squares at the bottom left of the video frames.
