Intra prediction and intra mode coding
A device includes one or more processors configured to derive, from among a plurality of intra prediction modes, M most probable modes (MPMs) for intra prediction of a block of video data. A syntax element indicating whether a MPM index or a non-MPM index is used to indicate a selected intra prediction mode of the plurality of intra prediction modes for intra prediction of the block of video data is decoded. Based on the indicated one of the MPM index or the non-MPM index being the MPM index, the one or more processors select, for each of one or more context-modeled bins of the MPM index, based on intra prediction modes used to decode one or more neighboring blocks, a context index for the context-modeled bin. The one or more processors reconstruct the block of video data based on the selected intra prediction mode.
