Use native FFmpeg v360 filter, it supports more features that any other solution.

You need the v360 filter (make sure you use the latest ffmpeg build as older versions don't include it).

For instance:

-vf v360=equirect:c3x2

3x2/6x1/1x6 cubemap layouts are available.

You can try out by compiling with the transform filter, developed by Facebook

Transform

Transform is a video filter that transforms 360 video in equirectangular projection into a cubemap projection

Build Instructions:

Transform is implemented as an ffmpeg video filter. To build Transform, follow these steps:

Checkout the source for ffmpeg

Copy vf_transform.c to the libavfilter subdirectory in ffmpeg source

Edit libavfilter/allfilters.c and register the filter by adding the line: REGISTER_FILTER(TRANSFORM, transform, vf); in the video filter registration section

Edit libavfilter/Makefile and add the filter to adding the line: OBJS-$(CONFIG_TRANSFORM_FILTER) += vf_transform.o in the filter section

Configure and build ffmpeg as usual

Works very well, thanks for pointing out this recent ressource. I haven't found yet how to make it work with OSX brew workflow but it's super easy to get running on Linux — Guig, Feb 03 '16 at 19:46
