Using cameraundistort plugin with calculated distortion coefficient

[yasoua]

I need someone please to explain to me how can i use distortion coefficient
already calculated using a specific python code  ( dist [[7.33183864e+03
1.52395233e-01 2.53983049e+00 2.20587897e+00
  2.61869010e-06]] ) with cameraundistort plugin.

I have seen the following example pipeline in the documentation : 
 
gst-launch-1.0 -v v4l2src ! videoconvert ! cameraundistort settings="???" !
autovideosink

But i dindn't get what kind of argument i should give to settings , is this
where i should put my calculated distortion coefficient or my matrix? 

Thanks in advance
