Described herein is a video encoder that includes a memory unit, a selector, and an encoding processor. The memory unit stores a plurality of pictures. The selector accesses the plurality of pictures in the memory unit. The selector initially accesses a first picture, followed by another picture, followed by one or more pictures. The one or more pictures are presented to the video encoder between the first picture and the another picture. The encoding processor encodes the first picture independently, then encodes the another picture independently, and finally, the one or more pictures are encoded. The output of the encoding processor is a first coded picture, another coded picture, and one or more coded pictures respectively.
