The various embodiments described herein include methods and systems for encoding and decoding video. In one aspect, a method includes obtaining video data comprising a plurality of blocks, including a first block, from a video bitstream. The method further includes predicting a set of parameters for filtering the first block, where the set of parameters are not explicitly signaled in the video bitstream. The method also includes obtaining a filtered first block by applying a cross-component sample offset (CCSO) to the first block, where the CCSO is based on the set of parameters. The method also includes reconstructing a picture from the video data using the filtered first block.
