Abstruct of GoPro Max .360 video file format is described in: https://gopro.com/news/max-tech-specs-stitching-resolution The specification is little bit buggy. The format is based on EAC (Equi-Angular Cubemap), and there are overlapped pixels at boundaries of front and rear cams. Probably, the desinger intended to add 2 x 32 (= total 64) ovelapped pixels. But actual format has 2 x 64 pixels overlapped area. Thus the width will be 2 x 32 pixels shorter than standard EAC format after blending overlapped area. This filter brends overlapped area, stretches the width of the cube, and combine two streams into single stream with standard format.
