ABSTRACT:
Sequential video data frames are encoded using cores including a first core and a second core. A first beginning frame is divided into slices. The first core is assigned to process a first slice. The second core is assigned to process a second slice. The first beginning frame is processed using the cores which results in a first ending frame in which the first slice was partitioned into a third slice and a fourth slice. The third slice was processed by the first core. The fourth slice and the second slice were processed by the second core. A second beginning frame, which immediately follows the first ending frame, is divided into a second plurality of slices. The first core is assigned to the third slice. The second core is assigned to a fifth slice which has a size equal to a sum of the second and fourth slices.
