Test the five public functions not already covered by tests/color_utils: av_csp_luma_coeffs_from_avcsp, av_csp_primaries_desc_from_id, av_csp_primaries_id_from_desc, av_csp_approximate_trc_gamma, and av_csp_approximate_eotf_gamma. Iterates every AVCOL_SPC, AVCOL_PRI, and AVCOL_TRC value including the extended ranges, round-trips primaries via desc_eq so the canonical first-match (e.g. smpte170m for smpte240m) is accepted, checks that a garbage desc returns AVCOL_PRI_UNSPECIFIED, and that out-of-range enum values return NULL or 0.0 as documented. The trc/eotf gamma values come from static lookup tables so the floating point output is bitexact across platforms. Coverage for libavutil/csp.c: 88.50% -> 94.46% |
