Previously, the code only stored the MIP mode and transpose flag in the relevant tables at the top-left corner of the CU. This information ends up being retrieved in ff_vvc_intra_pred_* not based on the CU position but instead the transform unit position (specifically, using the x0 and y0 from get_luma_predict_unit). There might be multiple transform units in a CU, hence the top-left corner of the transform unit might not coincide with the top-left corner of the CU. Consequently, we need to store the MIP information at all positions in the CU, not only its top-left corner, as we already do for the MIP flag. Signed-off-by: Frank Plowman <post@frankplowman.com>
