+@section colorstats, colorrgbstats, coloryuvstats
+The filter provides statistical video measurements such as mean, minimum,
maximum and
+standard deviation for each frame. The user can check for
unexpected/accidental errors
+very quickly with them.
+
+@var{colorrgbstats} report the color stats for RGB input video,
@var{coloryuvstats}
+to an YUV input video.
+
+These filters accept the following parameters:
+@table @option
+@item planes
+Set which planes to filter. Default is only the first plane.
+@end table
+
+By default the filter will report these metadata values if the planes
+are processed:
+
+@table @option
+@item min.y, min.u, min.v, min.r, min.g, min.b, min.a
+Display the minimal Y/U/V/R/G/B/A plane value contained within the input frame.
+Expressed in range of [0, 1<<bitdepth-1]
+
+@item pmin.y, pmin.u, pmin.v, pmin.r, pmin.g, pmin.b, min.a
+Display the minimal Y/U/V/R/G/B/A plane percentage of maximum contained within
+the input frame. Expressed in range of [0, 1]
+
+@item max.y, max.u, max.v, max.r, max.g, max.b, max.a

+Expressed in range of [0, 1<<bitdepth-1]
+
+@item pmax.y, pmax.u, pmax.v, pmax.r, pmax.g, pmax.b, pmax.a

+
+@item mean.y, mean.u, mean.v, mean.r, mean.g, mean.b, mean.a
+Display the Y/U/V/R/G/B/A plane mean value contained within the input frame.
+Expressed in range of [0, 1<<bitdepth-1]
+

+the input frame. Expressed in range of [0, 1]
+
+@item stdev.y, stdev.u, stdev.v, stdev.r, stdev.g, stdev.b, stdev.a
