Abstract: A device for decoding video data is configured to perform interpolation filtering using an N-tap filter to generate an interpolated search space for a first block of video data; obtain a first predictive block in the interpolated search space; determine that a second block of video data is encoded using a bi-directional inter prediction mode and a bi-directional optical flow (BIO) process; perform an inter prediction process for the second block of video data using the bi-directional inter prediction mode to determine a second predictive block; perform the BIO process on the second predictive block to determine a BIO-refined version of the second predictive block, wherein a number of reference samples used for calculating intermediate values for BIO offsets is limited to a region of (W+N-1)x(H+N-1) integer samples, wherein W and H correspond to a width and height of the second block in integer samples.

Abstract: A device for video decoding a current block of video data, the device including one or more processors configured to compute a horizontal component of a motion vector and to compute a vertical component of a motion vector in an affine model. The affine model may be a four-parameter affine model which includes two control point motion vectors, or a six-parameter affine model which includes three control point motion vectors. The horizontal and vertical components may include differences between control point motion vectors based on first-bit shift operations and second bit-shift operations.

Abstract: A video decoder can be configured to decode a block of video data by determining a block of video data is coded in an intra prediction mode; determining one or more samples for intra predicting the block of video data, wherein the one or more samples comprise samples that are already reconstructed and not adjacent to the block of video data; and based on the one or more samples, generating a predictive block for the block of video data.

Abstract: A device for video decoding can be configured to obtain, from a syntax structure in a bitstream comprising an encoded representation of the video data, a syntax element indicating whether 6-parameter affine prediction is enabled for blocks corresponding to the syntax structure, wherein the blocks corresponding to the syntax structure comprise a first block; based on the syntax element indicating that the 6-parameter affine prediction is enabled for the blocks corresponding to the syntax structure, use the 6-parameter affine prediction to generate a predictive block for the first block; and use the predictive block and residual data to reconstruct the first block.
