Method and apparatus for video coding

Abstract

A method and apparatus of transform processing for non-power-of-2 blocks are disclosed. According to this method, if the current block is a non-power-of-2 block and transform kernels for the current block do not support non-power-of-2 transforms: the current block is processed by using a target process from a process group comprising a first process, a second process or both, wherein the first process comprises splitting the current block into multiple blocks supported by the transform kernels; and applying forward or backward transform process to the multiple blocks; and wherein the second process comprises encoding or decoding residual samples of the current block directly by skipping transform process.
