Abstract
An example method of video decoding includes receiving a video bitstream comprising a set of encoded blocks and a corresponding set of transform coefficients. The method also includes selecting a non-separable secondary transform from a set of one or more non-separable secondary transforms based an index value. The method further includes determining, based on coded information, a kernel size and kernel shape for the non-separable secondary transform, and decoding the set of encoded blocks by applying the non-separable secondary transform with the determined kernel size and kernel shape to the set of encoded blocks.
