Abstract
Disclosed in the embodiments of the present application are an inter-frame prediction method, an encoder, a decoder, and a computer storage medium, comprising: parsing a code stream to acquire a prediction mode parameter of a current block; when the prediction mode parameter indicates that an inter-frame prediction mode is used for determining an inter-frame prediction value of a current block, determining a first motion vector of a current sub-block of the current block; on the basis of the first motion vector, determining a first prediction value of the current sub-block, and determining a target pixel position corresponding to a current pixel position; the current pixel position is the position of a pixel point in the current sub-block, and the target pixel position is the position of a pixel point for performing secondary prediction or PROF processing on the pixel point of the current pixel position; if the target pixel position does not belong to the current sub-block, then performing update processing on the target pixel position on the basis of the current sub-block to acquire an updated pixel position; on the basis of the first prediction value and the updated pixel position, determining a second prediction value corresponding to the current sub-block, and determining the second prediction value to be an inter-frame prediction value of the current sub-block.
