Abstract
Block parallel fast motion estimation for blocks of a video frame is provided where encoding of video blocks can be ordered to allow concurrent encoding thereof. Furthermore, motion vector prediction can be performed concurrently for independent video blocks where requisite blocks for calculating the prediction of a given block can be previously encoded, but not all blocks depend from each other; thus, parallel motion vector estimation is possible. Additionally, a fast motion estimation algorithm can be concurrently performed on a number of video blocks to search surrounding blocks to compute motion vectors as well. The concurrent processes can leverage the parallel architecture of one or more graphical processing units (GPU).
