Abstract:
1. A method of coding video data, the method comprising: determining a block size associated with a current block of video data, the block size determined from a plurality of block sizes including a 4×4 block size, an 8×8 block size, a 16×16 block size, and a 32×32 block size; determining an intra-prediction coding mode associated with the current block of video data, the intra-prediction coding mode determined from a plurality of intra-prediction coding modes including a horizontal mode, a vertical mode, a planar mode, a DC mode, and a plurality of diagonal modes, including an upper-left diagonal mode, an upper right diagonal mode, a down-left diagonal mode and wherein the plurality of diagonal modes include a plurality of modes that are directly adjacent to the horizontal mode or the vertical mode; determining based on the block size and intra-prediction coding mode a filtering decision for whether to apply a filter to prediction samples used to predict the current block, the determining comprising: intra-predictive coding the current block, wherein intra-predictive coding the current block comprises using the determined filtering decision to either filter or not filter the pixels used to predict the current block.
