Abstract
A video encoding, decoding method and a decoder are disclosed. The method includes: decoding a bitstream to determine a first-type intra prediction mode parameter of a current block; determining first prediction values of the current block according to the first-type intra prediction mode parameter; determining a first transform parameter of the current block based on the first prediction values of the current block or the first-type intra prediction mode parameter of the current block; determining, based on the first transform parameter, a second transform parameter for transforming the current block; transforming, based on the second transform parameter, transform coefficients of the current block to determine residuals of the current block; and determining reconstructed values of the current block based on the residuals and the first prediction values.
