API changes, most recent first:
2016-xx-xx - xxxxxxx - lavc 57.29.0 - avcodec.h
Add AV_PKT_DATA_SPHERICAL packet side data to export AVSphericalMapping
information from containers.
2016-xx-xx - xxxxxxx - lavu 55.30.0 - spherical.h
Add AV_FRAME_DATA_SPHERICAL value, av_spherical_alloc() API and
AVSphericalMapping type to export and describe spherical video properties.
