@ -17846,6 +17848,12 @@ The @code{nullsrc} source returns unprocessed video frames. It is
mainly useful to be employed in analysis / debugging tools, or as the
source for filters which ignore the input data.
The @code{pal75bars} source generates a color bars pattern, based on
EBU PAL recommendations with 75% color levels.
The @code{pal100bars} source generates a color bars pattern, based on
EBU PAL recommendations with 100% color levels.
The @code{rgbtestsrc} source generates an RGB test pattern useful for
detecting RGB vs BGR issues. You should see a red, green and blue
stripe from top to bottom.
