History-based motion vector prediction for affine mode

Abstract:

A method of coding video data, including coding a first block of video data using affine motion compensation prediction, updating a history-based motion vector prediction table using one or more motion vectors from one or more blocks that spatially neighbor the first block, determining a motion vector for a second block of video data using the history-based motion vector prediction table, and coding the second block of video data using the determined motion vector.
