Interframework prediction methods, encoders and decoders

Abstract

The invention relates to a method for predicting interframes, a codec, a codec, and a computer-readable storage medium. The method is applied to a decoder. The method includes: code line splitting, and parameterizing the prediction method of the current block; when parameterizing the prediction method, it indicates the use of the built-in inter-frame prediction method to determine the inter-frame prediction value of the current block, determining at least one initial reserve position of the current block; When at least one initial reserve position exceeds the range of the Largest Coding Unit (LCU) of the current block, adjust at least one initial reserve position to obtain at least one destination reserve position of the current block; based on at least one destination reserve position, determine at least one time-domain motion information of the current block; based on at least one time-domain motion information, establish a new motion information reserve list; And according to this new list of specialized information reserves, determine the inter-frame prediction value of the current block.
