Field Documentation

dm_metadata_id

uint8_t AVDOVIColorMetadata::dm_metadata_id

Definition at line 172 of file dovi_meta.h.

scene_refresh_flag

uint8_t AVDOVIColorMetadata::scene_refresh_flag

Definition at line 173 of file dovi_meta.h.

ycc_to_rgb_matrix

AVRational AVDOVIColorMetadata::ycc_to_rgb_matrix[9]

Coefficients of the custom Dolby Vision IPT-PQ matrices.

These are to be used instead of the matrices indicated by the frame's colorspace tags. The output of rgb_to_lms_matrix is to be fed into a BT.2020 LMS->RGB matrix based on a Hunt-Pointer-Estevez transform, but without any crosstalk. (See the definition of the ICtCp colorspace for more information.)
