Paul,
v_fov is limited to 90°, that's not enough for little planet.
I increased it.
ok, I will test it as soon as it's available at Zeranoe.
I think the field of view isn't correct in the stereographic output.
Here is a script for making really nice test images, for measuring field
of view:
set "IN=1200.png" :: Test pattern from
http://www.paulbourke.net/dome/testpattern/1200.png
set "OUT=double_fisheye_test.png" :: Double fisheye test image
ffmpeg -i %IN% -i %IN% -lavfi
"[0]transpose=1[left];[1]transpose=2,geq=r='255-r(X,Y)':g='255-g(X,Y)':b='255-b(X,Y)'[right];[left][right]hstack"
-y %OUT%
set "IN=double_fisheye_test.png"
set "OUT=equirectangular_test.png" :: Equirectangular test image
ffmpeg -i %IN% -lavfi "v360=input=dfisheye:output=e:pitch=90" -y %OUT%
