Zusammenfassung:An example device includes memory configured to store video data and one or more processors implemented in circuitry and coupled to the memory. The one or more processors determine whether a chroma block of the video data is encoded using dual tree partitioning. The one or more processors determine whether transform skip mode for the chroma block is enabled. The one or more processors, based on the chroma block being encoded using dual tree partitioning and transform skip mode being enabled for the chroma block, infer a value of a low-frequency non-separable transform (LFNST) index for the chroma block.
