Abstract
An inter prediction method includes: determining, when a current prediction mode of a current prediction block is a preset prediction mode, a historical prediction mode corresponding to the current prediction block; acquiring adjacent block information about an adjacent block of the current prediction block, prediction sub-block information about a prediction sub-block, and a historical optimal reference frame type of the current prediction block in the historical prediction mode; generating a reference frame mask based on the historical optimal reference frame type, the adjacent block information, the prediction sub-block information, and a frame type corresponding to the current prediction block; and determining a reference frame of the preset prediction mode using the reference frame mask, and performing inter prediction on the current prediction block using the reference frame to obtain a prediction value corresponding to the current prediction block.
