1. A method comprising:
encoding, by a processor, a first coding unit (CU) in a picture;
determining, by the processor, a consumed virtual memory access (VMA) bandwidth for the first CU;
limiting, by the processor, a maximum number of reference pictures for motion estimation for a second CU in the picture based on the consumed VMA bandwidth for the first CU; and
encoding, by the processor, the second CU using the limited maximum number of reference pictures for motion estimation.
