Function av_csp_luma_coeffs_from_avcsp

pub unsafe extern "C" fn av_csp_luma_coeffs_from_avcsp(
    csp: u32,
) -> *const AVLumaCoefficients

Retrieves the Luma coefficients necessary to construct a conversion matrix from an enum constant describing the colorspace. @param csp An enum constant indicating YUV or similar colorspace. @return The Luma coefficients associated with that colorspace, or NULL if the constant is unknown to libavutil.
