1. A method of filtering video data in a video coding process comprising: receiving a block of video data, wherein the block of video data includes a plurality of sample values; determining filter coefficients for the block of video data for an adaptive loop filter (ALF), wherein determining the filter coefficients for the block of video data includes determining the AC coefficients and not determining any DC coefficients; determining a respective offset value for each of the plurality of sample values based at least in part on a value associated with the filter coefficients, wherein the respective offset values are for a sample adaptive offset (SAO) filter; and filtering the block of video data based on the determined filter coefficients and the determined respective offset values without filtering the block of video data based on the DC coefficient for the ALF that is not determined.
