Abstract: Methods and systems may provide for determining, on a graphics processor, an intra prediction error for a coding unit of a video frame and selectively bypassing, on a host processor, an intra prediction coding stage with respect to one or more of a recursive split decision or an encoding mode selection based at least in part on the intra prediction error. In one example, an inter prediction error may also be determined, on the graphics processor, wherein the intra prediction coding stage is selectively bypassed further based on the inter prediction error.

Abstract: Techniques related to selecting intra-prediction angular modes for video encoding are discussed. Such techniques may include evaluating, for a coding unit, encoding costs for only a subset of available intra-prediction angular modes, selecting one or more of the subset as candidate modes based on lowest encoding costs, evaluating encoding costs for neighbors of the selected candidate modes, and providing final candidate modes based on the evaluated encoding costs.
