Abstract: A method of decoding video data includes receiving a block of video data, determining an intra prediction mode for the block of video data, and determining whether or not to use a position-dependent prediction combination (PDPC) mode to decode the block of video data based at least on the determined intra prediction mode. The method may also include receiving a syntax element associated with a primary transform or a secondary transform used for a block of video data, determining a usage of one or more video coding tools based on a value of the syntax element, the one or more video coding tools being video coding techniques other than the primary transform or secondary transform, and applying the one or more coding tools to the block of video data based on the determined usage.

Abstract: Techniques are described in which a decoder is configured to receive an input data block and apply an inverse non-separable transform to at least part of the input data block to generate an inverse non-separable transform output coefficient block. The applying the inverse non-separable transform comprises assigning a window, assigning a weight for each position inside the assigned window, and determining the inverse non-separable transform output coefficient block based on the assigned weights. The decoder is further configured to forming a decoded video block based on the determined inverse non-separable transform output coefficient block, wherein forming the decoded video block comprises summing the residual video block with one or more predictive blocks.

Abstract: Processing circuitry of a device is configured to determine that a plurality of derived modes (DMs) available for predicting a luma block of video data are also available for predicting a chroma block of the video data, the chroma block corresponding to the luma block, to form a candidate list of prediction modes with respect to the chroma block, the candidate list including one or more DMs of the multiple DMs, to determine to code the chroma block using any DM of the candidate list. The processing circuitry may, based on the determination to code the chroma block using any DM of the one or more DMs of the candidate list, code an indication identifying a selected DM of the candidate list to be used for coding the chroma block. The processing circuitry may code the chroma block according to the selected DM of the candidate list.
