Abstract: An example video decoder is configured to decode a first value for a first syntax element of a current block of video data, the first value indicating that the current block is encoded using an intra-prediction mode; after decoding the first value, decode a second value for a second syntax element of the current block, the second value indicating that the current block is encoded using intra mapping mode. In the intra mapping mode, the video decoder is configured to generate a prediction block for the current block using the intra-prediction mode and decode a residual block. To decode the residual block, the video decoder is configured to determine predictors for quantized residual values of the residual block and map decoded mapping values to the quantized residual values using the predictors. The video decoder combines the prediction block with the residual block to decode the current block.

Abstract: A video coder is configured to code video data using triangular partitions. The video coder may determine a size of a block of video data, and disable a partitioning mode that includes triangular prediction units based on the size of the block of video data, wherein disabling the partitioning mode that includes triangular prediction units removes the partitioning mode from available coding modes. For example, the video coder may disable the partitioning mode that includes triangular prediction units in the case that the width or the height of the block is larger than a threshold. The video coder may then code the block of video data with one or more of the available coding modes.
