Abstract: In a method for video encoding, whether an angular intra prediction mode for a current block is a wide angle mode is determined. The current block is a non-square block and the wide angle mode is in a direction outside of a range of directions that spans a bottom left diagonal direction and top right diagonal direction of the current block. In response to determining that the angular intra prediction mode is the wide angle mode, whether a block size of the non-square block is greater than 32 is determined. In response to determining that the block size of the non-square block is greater than 32, an intra smoothing filter is enabled and the enabled intra smoothing filter is applied to blocks neighboring the current block to generate filtered blocks. A characteristic value of the current block is encoded in a bitstream based on the filtered blocks.
