1. A method comprising:
receiving, by one or more processors, a video data that includes a largest coding unit (LCU);
performing, by the one or more processors, intra-prediction on each coding unit (CU) of the LCU beginning with a smallest size CU to determine an intra-prediction coding cost for each of the CUs;
performing, by the one or more processors, inter-prediction on each CU of the LCU beginning with the smallest size CU to determine an inter-prediction coding cost for each of the CUs;
selecting, by the one or more processors, a best prediction mode for each CU of the LCU based on the inter-prediction coding cost for each of the CUs and the intraprediction coding cost for each of the CUs;
determining, by the one or more processors, whether a current CU is a parent CU; and
in response to determining the current CU is the parent CU, selecting, by the one or more processors, a CU partition.
