Abstract: A video coding device may be configured to perform video coding according to one or more of the techniques described herein. In one example, a method of coding of video data comprises determining a predictive quantization parameter for an array of level values based at least in part on one or more of: a picture quantization map and a quantization parameter value of a video block included in a reference picture, generating a quantization parameter for the array based at least in part on the determined predictive quantization parameter, and performing an inverse quantization operation on the array using the generated quantization parameter.

Abstract: A device determines a Compact Multi-Pass Transform (CMPT) from a plurality of CMPTs. Additionally, the device decompresses CMPT parameters for the CMPT. In instances where the device decodes video data, the device applies the CMPT to a coefficient block to reconstruct a residual block and decodes, based on a predictive block and the residual block, a current block of a picture of the video data. In instances where the device encodes video data, the device applies the CMPT to a residual block to construct a coefficient block and generates for output information indicating coefficient values for the coefficient block.
