INTER-FRAME PREDICTION METHOD AND APPARATUS, ELECTRONIC DEVICE, COMPUTER-READABLE STORAGE MEDIUM, AND COMPUTER PROGRAM PRODUCT

The present application provides an inter-frame prediction method and apparatus, an electronic device, a computer-readable storage medium, and a computer program product. Said method comprises: when the current prediction mode of a current prediction block is a preset prediction mode, determining historical prediction modes corresponding to the current prediction block; acquiring adjacent block information of adj acent blocks of the current prediction block, sub-prediction block information of sub-prediction blocks, and a historical optimal reference frame type of the current prediction block in the historical prediction modes; on the basis of the historical optimal reference frame type, the adj acent block information and the sub-prediction block information, and a frame type corresponding to the current prediction block, generating a reference frame template; and determining a reference frame of the preset prediction mode by using the reference frame template, and performing inter-frame prediction on the current prediction block by using the reference frame to obtain a prediction value corresponding to the current prediction block. The present application can increase the video coding efficiency.
