Comment (by mkoch):
Most probably the right sides of the borders are always at WIDTH/4 and
WIDTH*3/4, and the left side is at one pixel less. It would be a little
bit more complicated if WIDTH isn't a multiple of 4.
There is no need for two separate processes. In the filter chain you can
first use the v360 filter and then the geq filter, separated by a comma:
-vf "v360=input=dfisheye:output=e,geq=..."
You find more examples for remap and v360 in my book:

I agree with you that smoothing would be a nice enhancement for the v360
filter.
