Abstract
Various embodiments relating to selecting a motion vector in a hardware encoder are disclosed. In one example, a plurality of candidate predicted motion vectors are selected, and a plurality of motion searches are performed in an image region surrounding each candidate predicted motion vector to produce a plurality of resulting motion vectors, wherein each resulting motion vector has an initial cost score determined using a corresponding candidate predicted motion vector. After an actual predicted motion vector becomes available, the initial cost score of each resulting motion vector is re-scored using the actual predicted motion vector to produce an updated cost score, and video data is encoded using a motion vector selected from the plurality of resulting motion vectors based on the updated cost score of that motion vector.
