./ffmpeg/libavutil/spherical.c:59:14: warning: comparison of
constant 8 with expression of type 'enum AVSphericalProjection'
is always false
[-Wtautological-constant-out-of-range-compare]
if (type >= FF_ARRAY_ELEMS(spherical_projection_names))
you gotta use unsigned int as the first argument
not required but nice to have would be the opposite function so that
you can get the projection type from a string.
