sws_scale_frame (used since 17.0.0) validates color_trc/color_primaries and rejects RESERVED and other unsupported values (e.g. LOG) with EOPNOTSUPP, regressing plain reformat/to_ndarray to rgb24 on VP9 and NVDEC frames. The pre-17.0 sws_scale ignored these fields. Neutralize color_trc/color_primaries to UNSPECIFIED for the scale unless a destination value is explicitly requested, while preserving the source's tags on the returned frame. The YUV->RGB matrix and explicit conversions are unaffected.
