Loop filtering and encoding and decoding method, electronic equipment, storage medium and program product

The embodiment of the invention provides a loop filtering and encoding and decoding method, electronic equipment, a storage medium and a program product. The loop filtering method comprises the following steps: determining a reference image block corresponding to a to-be-processed image block in a reference frame adjacent to the to-be-processed image block in a time domain, and predicting a loop filtering opening probability of the to-be-processed image block according to a loop filtering result of the reference image block; determining spatial coding information of the to-be-processed image block, wherein the spatial coding information is used for representing texture complexity of the to-be-processed image block; and if the spatial coding information and the loop filtering opening probability meet the preset filtering condition, performing loop filtering decision on the to-be-processed image block. According to the scheme provided by the embodiment of the invention, whether the loop filtering decision is pe
