Unable to convert dual fisheye image to equirectangular image using ffmpeg package

Question

I am trying to convert dual fisheye image captured in an insta360 camera to equirectangular format using the ffmpeg package but I am unable to get the correct result. I used the following code,

ffmpeg -i input.jpg -vf v360=dfisheye:equirect:ih_fov=360:iv_fov=360 output.jpg

the input image,input_image

the output image, output_image

thank you in advance.

Answer 1

Bot horizontal and vertical Field Of View of the cameras can't be 360, they are by sure just a little more than 180, try this:

ffmpeg -i input.jpg -vf v360=dfisheye:equirect:ih_fov=190:iv_fov=190 output.jpg

Hint: add "yaw" parameter to move the camera right and left:

ffmpeg -i input.jpg -vf v360=dfisheye:equirect:ih_fov=190:iv_fov=190:yaw=90 output.jpg
