Abstract
System and method for improving operational efficiency of a video encoding pipeline used to encode image data. The video encoding pipeline includes a motion estimation setup block, which dynamically adjusts a setup configuration of the motion estimation block based at least in part on operational parameters of the video encoding pipeline and select an initial candidate inter-frame prediction mode based at least on the setup configuration, a full-pel motion estimation block, which determines an intermediate candidate inter-frame prediction mode by performing a motion estimation search based on the initial candidate inter-frame prediction mode, a sub-pel motion estimation block, which determines a final candidate inter-frame prediction by performing a motion estimation search based on the intermediate candidate inter-frame prediction mode, and a mode decision block, which determines a rate-distortion cost associated with the final candidate inter-frame prediction mode and determines a prediction mode used to prediction encoding the image data.
