1. A method comprising:
determining intra-prediction coding costs for each of a plurality of coding units (CUs) of a largest coding unit (LCU) beginning with a smallest CU of the plurality of CUs; and
performing CU partition selection on each of the plurality of CUs based on the intra-prediction coding costs and prediction unit (PU) partition types for each of the plurality of CUs and inter-prediction coding costs and PU partition types for each of the plurality of CUs to determine a CU partitioning.
