Abstract
A video coder determines a first block of the video data is intra mode coded; based on a first height and the first width of the first block, identifies a group of N available intra prediction modes for the first block of video data; selects from the group of N available intra prediction modes, a first intra prediction mode used to code the first block of the video data; and codes the first block using the first intra prediction mode. A video coder generates a first most probable mode (MPM) candidate list for the block; codes a first flag indicating an actual intra prediction mode used to code the block is not included in the first MPM candidate list; generates a second MPM candidate list by deriving at least one candidate intra prediction mode based on an intra prediction mode in the first MPM candidate list.
