    Abstract: An example method of encoding video data includes determining a resolution that will be used for a motion vector that identifies a predictor block in a current picture of video data for a current block in the current picture of video data; determining, based on the determined resolution, a search region for the current block such that a size of the search region is smaller where the resolution is fractional-pixel than where the resolution is integer-pixel; selecting, from within the search region, a predictor block for the current block; determining the motion vector that identifies the selected predictor block for the current block; and encoding, in a coded video bitstream, a representation of the motion vector.

    Abstract: According to techniques of this disclosure, a video decoder can be configured to, for one or more blocks coded with wavefront parallel processing enabled, determine a coding tree block (CTB) delay, wherein the CTB delay identifies a delay between when a first row of CTBs starts being decoded and when a second row of CTBs below the first row of CTBs starts being decoded; for a current block of video data coded in an intra-block copy (IBC) mode and coded with wavefront parallel processing disabled, determine an IBC prediction region for the current block within a picture that includes the current block based on the CTB delay that was determined for the one or more blocks coded with wavefront parallel processing enabled; identify, from within the determined IBC prediction region for the current block, a predictive block for the current block; and IBC decode the current block based on the predictive block.

    Abstract: A video coding device may encode and/or decode video data. The video coding device encodes a first video block in a first picture by predicting values of the first video block based on a previously encoded video block in a second picture different than the first picture. The video coding device filters the first video block according to a deblocking filtering process. The video coding device encodes a second video block in the first picture by predicting values of the second video block based on a previously encoded video block in the first picture. The video coding device filters the second video block according to the deblocking filtering process. The video coding device decodes the first video block, filters the first video block according to the deblocking filtering process, decodes the second video block, and filters the second video block according to the deblocking filtering process.

    Abstract: A video coder may determine a search region for coding a current block of video data using Intra Block Copy (Intra BC). In some examples, the video coder determines a central point for the search region, and determines the search region for the current block based on the central point and a defined size for the search region. The video coder stores reconstructed blocks of the video data from a current picture that includes the current block in a memory based on the determined search region. The video coder codes information from which to identify one of the reconstructed blocks within the search region, and codes the current block based on the identified one of the reconstructed blocks according to Intra BC.
