Abstract: An example method of video decoding includes decoding prediction information for a current block, the prediction information indicating a plurality of combinations of processed reconstructed samples and corresponding output values of a filtering process. The method also includes performing the filtering process on processed reconstructed samples of a first color component of the current block, the processed reconstructed samples of the first color not being included in the plurality of combinations of the processed reconstructed samples indicated in the prediction information. The method further includes determining an output value of the filter process based on one of: a default value, a predicted output value, and one of the output values indicated in the prediction information; and reconstructing the current block based on the output value being applied to reconstructed samples of a second color component of the current block, the second color component being different from the first color component.
