Abstract
A method for video encoding is provided. The method includes obtaining, by an encoder, a plurality of blocks from a video picture, wherein each of the plurality of blocks is to be encoded by an intra prediction mode or an inter prediction mode; in response to a first pre-defined condition being satisfied, determining, by the encoder, that a current block in the plurality of blocks is eligible for an application of Decoder-side Motion Vector Refinement (DMVR); in response to the current block being eligible for both applications of DMVR and Bi-Directional Optical Flow (BDOF), determining, by the encoder, whether a pre-defined criterion based on mode information of the current block is satisfied; avoiding, by the encoder in response to the pre-defined criterion being satisfied, applying BDOF to a subblock in the current block; and outputting, by the encoder by a bitstream, prediction mode information of the current block.
