Abstract
A method for encoding a video stream having a plurality of blocks including a current block. The method includes identifying, from a plurality of previously coded blocks, a plurality of candidate motion vectors; identifying, for the current block, a set of reconstructed pixel values corresponding to a set of previously coded pixel values; determining, for at least one of the plurality of candidate motion vectors, an error value based on the set of reconstructed pixel values and a set of predicted values for the set of previously coded pixel values; and selecting, from the plurality of candidate motion vectors, a reference motion vector for the current block based on the error value.
