Detailed Description

Per-frame color information for a RAW camera codec.

Carried as side data of type AV_FRAME_DATA_RAW_COLOR_PARAMS.

The outer struct carries the fields every RAW codec exposes: the sensor's valid sample range and the white-balance correlated color temperature. The codec union holds the codec-specific transform parameters; type selects which member of the union is valid.

The codec-specific transform (color_matrix or equivalent) always lands in linear-light CIE 1931 XYZ relative to the D65 illuminant, cameras don't have standard primaries, so XYZ is the only common target.

Note

The struct must be allocated using av_raw_color_params_alloc() or av_raw_color_params_create_side_data(). Its size is not a part of the public ABI.
