    Abstract: Techniques are described using Position Dependent Intra Prediction Combination (PDPC) with wide angle intra prediction. For example, a size of the current block of video data can be determined. Based on the size, a wide angle intra-prediction mode can be determined for the current block. A prediction block for the current block can be determined using the wide angle intra-prediction mode. A prediction sample from the prediction block can be modified to generate a modified prediction sample using PDPC, which can include determining one or more reference samples that are external to the current block based on the wide angle intra-prediction mode, and modifying the prediction sample to generate the modified prediction sample based on the determined one or more reference samples.

    Abstract: An example device for coding (encoding or decoding) video data includes a memory for storing video data and one or more processors implemented in circuitry and configured to form an inter-prediction block for a current chrominance block of the video data; form an intra-prediction block for the current chrominance block of the video data; determine a number of neighboring blocks to a luminance block corresponding to the current chrominance block that are intra-prediction coded; determine a first weight and a second weight according to the number of neighboring blocks that are intra-prediction coded; apply the first weight to the inter-prediction block and the second weight to the intra-prediction block; combine the first weighted inter- prediction block and the second weighted intra-prediction block to form a prediction block for the current chrominance block; and code the current chrominance block using the prediction block.

    Abstract: A video coder associates a first boundary strength value with an edge in response to determining that a first video block or a second video block is associated with an intra-predicted coding unit (CU), where the edge occurs at a boundary between the first video block and the second video block. The video coder may associate a second or a third boundary strength value with the edge when neither the first video block nor the second video block is associated with an intra-predicted CU. The video coder may apply one or more deblocking filters to samples associated with the edge when the edge is associated with the first boundary strength value or the second boundary strength value. The third boundary strength value indicates that the deblocking filters are turned off for the samples associated with the edge.
