Abstract

According to techniques of this disclosure, a video decoder can be configured to, for one or more blocks coded with wavefront parallel processing enabled, determine a coding tree block (CTB) delay, wherein the CTB delay identifies a delay between when a first row of CTBs starts being decoded and when a second row of CTBs below the first row of CTBs starts being decoded; for a current block of video data coded in an intra-block copy (IBC) mode and coded with wavefront parallel processing disabled, determine an IBC prediction region for the current block within a picture that includes the current block based on the CTB delay that was determined for the one or more blocks coded with wavefront parallel processing enabled; identify, from within the determined IBC prediction region for the current block, a predictive block for the current block; and IBC decode the current block based on the predictive block.
