摘要： During a prediction stage of video coding, a video coder may use relatively longer interpolation filters to generate predictive sub-pixel values using values of reference integer pixels of a reference block of video data positioned in parallel relative to a scanning order associated with the block and may use relatively shorter interpolation filters to generate predictive sub-pixel values using values of reference integer pixels of the block positioned perpendicular relative to the scanning order, wherein a longer interpolation filter generally refers to a filter with relatively more filter coefficients, or “taps,” and a shorter filter generally refers to a filter with relatively fewer taps.

摘要： During a video coding process, a prediction block is generated for a CU. The CU has two or more prediction units. A computing device determines, based on sizes of one or more of the prediction units, whether to perform a smoothing operation on samples in a transition zone of the prediction block. The transition zone is located at a boundary between samples of the prediction block associated with different prediction units. If the computing device makes the determination to perform the smoothing operation, the smoothing operation is performed to smooth samples of the prediction block in the transition zone.

摘要： For each prediction unit (PU) belonging to a coding unit (CU), a video coder generates a candidate list. The video coder generates the candidate list such that each candidate in the candidate list that is generated based on motion information of at least one other PU is generated without using motion information of any of the PUs belonging to the CU. After generating the candidate list for a PU, the video coder generates a predictive video block for the PU based on one or more reference blocks indicated by motion information of the PU. The motion information of the PU is determinable based on motion information indicated by a selected candidate in the candidate list for the PU.

摘要： In one example, an apparatus includes a video encoder configured to partition a block of video data into a first geometric partition and a second geometric partition using a geometric motion partition line, wherein the block comprises N×N pixels, divide the block of video data into four equally-sized, non-overlapping (N/2)×(N/2) sub-blocks, and encode at least one of the sub-blocks through which the geometric motion partition line passes using a transform size smaller than (N/2)×(N/2). The video encoder may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks. In one example, a video decoder may inverse transform the sub-blocks, and may determine transform sizes for the sub-blocks based on whether the geometric motion partition line passes through the sub-blocks.
