摘要
An example method includes obtaining values of control point motion vectors (CPMVs) for a current block of video data selected for coding using affine mode; determining whether a memory bandwidth needed for accessing samples of a plurality of reference blocks derived based on the values of the CPMVs satisfies a bandwidth threshold; selectively modifying, based on whether the determined memory bandwidth satisfies the bandwidth threshold, a motion compensation method used to predict samples of the current block of video data; and predicting, using the selectively modified motion compensation method, the samples of the current block of video data from the samples of the plurality of reference blocks.
