what do you mean by "fixed padding"? There are only two options for 
"dfisheye", in_pad and out_pad.
If a double-fisheye camera has lenses with 205° field of view, then for 
stitching together the two hemispheres the in_pad value must be (205° - 
180°) / 205° = 0.122. When you restrict the in_pad range to [0...0.1], 
you are breaking something that did work perfectly before.
