Abstract: Techniques are described herein for processing video data using enhanced interpolation filters for intra-prediction. For instance, a device can determine an intra-prediction mode for predicting a block of video data. The device can determine a type of smoothing filter to use for the block of video data, wherein the type of the smoothing filter is determined based at least in part on comparing at least one of a width of the block of video data and a height of the block of video data to a first threshold. The device can further perform intra-prediction for the block of video data using the determined type of smoothing filter and the intra-prediction mode.

Abstract: Systems and techniques are described for processing video data. For example, an apparatus can obtain a block of video data encoded using inter-prediction. In some examples, the apparatus can determine a direction associated with the block of video data, for instance based on pixels of the block of video data, based on pixels of at least one neighboring block of the block of video data, or based on information associated with a geometric partitioning mode (GPM) associated with the block of video data. The apparatus can apply a non-separable transform to the block of video data, for instance to decode or encode the video data. In some examples, the apparatus can apply the non-separable transform to the block according to the direction associated with the block of video data.
