1. A method for filtering in video decoding, comprising:
reconstructing, by a processor, a first sample in a video of a coded video bitstream based on a non-linear mapping based filter with a first filter shape configuration of a plurality of filter shape configurations, the plurality of filter shape configurations including at least two filter shape configurations that are based on a same geometric shape and include a same number of filter taps, each of the filter taps of the at least two filter shape configurations being located at different positions;
determining, by the processor, a switch from the first filter shape configuration to a second filter shape configuration of the plurality of filter shape configurations; and
reconstructing, by the processor, a second sample in the video based on the non-linear mapping based filter with the second filter shape configuration.
