Abstract: This disclosure relates to adaptively reordering reference frames for video coding technologies. Template matching (TM) may be used to reorder the reference frames or reference frame pairs for each block by comparing the difference between the template of a current block and the template of a reference block with reference to the motion information of the spatial reference motion information (or spatial motion vectors) and/or temporal reference motion information (or temporal motion vectors). The difference between the template of current block and the template of the reference block may be calculated for each spatial reference motion information and/or temporal reference motion information, and marked as the score value of the associated reference frames or reference frame pairs. The available reference frames or reference frame pairs are ranked based on the score value.

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.
