simplevideomark

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 simplevideomarkdetect plugin.

Example launch line

 gst-launch-1.0 videotestsrc ! simplevideomark ! videoconvert ! ximagesink

Add the default black/white squares at the bottom left of the video frames.
