1. A method for decoding video data, comprising:
receiving a video bitstream including a current image frame, wherein the video bitstream comprises a high level syntax element indicating whether to apply cross-component sample offset (CCSO) filtering on the current image frame;
based on the high level syntax element, determining whether to apply CCSO offset filtering on the current image frame;
when CCSO filtering is applied to the current image frame:
identifying, in the video bitstream, a first syntax element for a first component CCSO flag indicating whether to apply CCSO filtering on a first color component of the current image frame; and
determining whether to apply CCSO filtering on a first color sample of the first color component based on the first syntax element; and
reconstructing the current image frame including the first color sample of the first color component.
