Methods and apparatus for adaptive loop filtering in video coding are provided. The adaptive loop filtering may be largest coding unit (LCU) based, may use adaptive loop filter types in which the vertical size of a filter type is less than the horizontal size, may use a predefined set of filter types in which the vertical size of the largest filter type in the set is less than the horizontal size of the largest filter type in the set, may use a single adaptive loop filter type, and/or may use a filter type that is a cross with a center shape of a size dependent on an aspect ratio of the cross.
