P. the additional maps dont fit the allocation of the equi-pic on the cube Convert transposed and horizontally flipped Equi-Angular Cubemap in side-by-side stereo format to equirectangular top-bottom stereo format: v360=eac:equirect:in_stereo=sbs:in_trans=1:ih_flip=1:out_stereo=tb. This package is divided into two parts: Basic functions for inter-conversion of different types of mappings associated with omni directional cameras, virtual reality and 360° videos, like cubemap, spherical projections, perspective projection and equirectangular projection. For correct conversion, determination of input angle is important. We also keep the previous version of the It includes a demo application and an invitation to convert an image of your choice to verify the code does what you seek.
