Hello,
I have a projector with a 180° fisheye lens in a dome. Things are easy
if the lens is at the center of the dome. Any input format can be
transformed to fisheye output with the v360 filter. But things are
getting complicated when the lens isn't at the dome's center. Let's

Paul,
Single-fisheye is done as output only currently, user need to set both
h_fov and v_fov.
I'm just testing the new single fisheye options and as far as I have
tested, everything looks good.
Would it be possible to add an option for filling the unused area with a
user-defined color,

Paul,
I'm working on dual fisheye output
I've tested the new "ball" output format and found no problems. It gives
the same output as my workaround with the remap filter.
The only thing that's still missing is single-fisheye as input and
output format, with a user-defined field of

Question:
If the input format is stereographic and the output format is
equirectangular, what's then the meaning of the h_fov and v_fov parameters?
Do they define the field of view of the stereographic input (that would
make sense),
or do they
Paul,
I'm working on dual fisheye output
I've tested double-fisheye input and output and found no problems. This
can also be used for tilting of 180° single-fisheye images:
set "IN=IMG_077.jpg" :: Input image or video
set "PITCH=0" :: Rotation angle around X axis

Cant you use here negate filter instead of geq?
oops, yes that would be better. I did search for "invert" and didn't

Single fisheye is little different.
