Abstract

Devices, systems and methods for using zero-units in video and image coding are described. In a representative aspect, a method for video coding includes making a determination, for a block of video data having at least a height or a width that is a non-power-of-two number of pixels, to encode the block of video data into a bitstream representation without a transform operation and performing an in-loop filtering on a result of the encoding,wherein a type of the in-loop filter is selected based on the determination.
