1. A method of decoding video data, the method comprising:
decoding a current block of video data to form a decoded block;
determining that a current sample of the decoded block neighbors a sample along a virtual boundary in the decoded block and neighbors one or more samples that are not along any virtual boundary in the decoded block;
selecting a selected sample from the one or more samples that are not along any virtual boundary in the decoded block;
computing a band classification for cross component sample adaptive offset (CCSAO) for the current sample using the selected sample and without using any other neighboring samples to the current sample; and
performing CCSAO on the current sample using the band classification.
