Blur the input video without impacting the outlines.
This filter accepts parameters as a list of @var{key}=@var{value} pairs,
separated by ":".
If the key of the first options is omitted, the arguments are
interpreted according to the syntax:
@var{luma_radius}:@var{luma_strength}:@var{luma_threshold}[:@var{chroma_radius}:@var{chroma_strength}:@var{chroma_threshold}]
A description of the accepted options follows.
@table @option
@item luma_radius, lr
@item chroma_radius, cr
Set the luma/chroma radius. The option value must be a float number in
Set the luma radius. The option value must be a float number in
the range [0.1,5.0] that specifies the variance of the gaussian filter
used to blur the image (slower if larger). Default value is 1.0.
@item luma_strength, ls
@item chroma_strength, cs
Set the luma/chroma strength. The option value must be a float number
Set the luma strength. The option value must be a float number
in the range [-1.0,1.0] that configures the blurring. A value included
in [0.0,1.0] will blur the image whereas a value included in
[-1.0,0.0] will sharpen the image. Default value is 1.0.
@item luma_threshold, lt
Set the luma threshold used as a coefficient to determine
whether a pixel should be blurred or not. The option value must be an
integer in the range [-30,30]. A value of 0 will filter all the image,
a value included in [0,30] will filter flat areas and a value included
in [-30,0] will filter edges. Default value is 0.
@item chroma_radius, cr
Set the chroma radius. The option value must be a float number in
the range [0.1,5.0] that specifies the variance of the gaussian filter
used to blur the image (slower if larger). Default value is 1.0.
@item chroma_strength, cs
Set the chroma strength. The option value must be a float number
in the range [-1.0,1.0] that configures the blurring. A value included
in [0.0,1.0] will blur the image whereas a value included in
