Abstract: Provided in the present application are a decoding method, a coding method, an electronic device and a computer-readable storage medium, which are applied in the technical field of video coding and decoding. The decoding method comprises: parsing a bit stream to determine a target flag in the bit stream and the value of the target flag, wherein the target flag is used for indicating whether tap coefficients of at least one filter use a shared nonlinear amplitude-limiting index; and if the value of the target flag is a first value, further acquiring a target nonlinear amplitude-limiting index from the bit stream, wherein the target nonlinear amplitude-limiting index is a nonlinear amplitude-limiting index shared by the tap coefficients of the at least one filter. In the embodiments of the present application, nonlinear amplitude-limiting indexes respectively corresponding to a plurality of tap coefficients of a filter can be represented by one target nonlinear amplitude-limiting index. Thus, for the same number of tap coefficients, the number of nonlinear amplitude-limiting indexes can be reduced, such that the bit overheads of the nonlinear amplitude-limiting indexes can be effectively reduced, thereby facilitating an improvement in the compression efficiency of a video.
