Abstract: In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine whether to use color-space conversion for a coding unit and set a value of a syntax element of the coding unit to indicate the use of color-space conversion. The video coder may apply a color-space transform process in encoding the coding unit. The video coder may decode the syntax element of the coding unit. The video coder may determine whether a value of the syntax element indicates that the coding unit was encoded using color-space conversion. The video coder may apply a color-space inverse transform process in decoding the coding unit in response to determining that the syntax element indicates that the coding unit was coded using color-space conversion.

Abstract: A video coding device configured according to some aspects of this disclosure includes a memory configured to store an initial list of motion vector candidates and a temporal motion vector predictor (TMVP). The video coding device also includes a processor in communication with the memory. The processor is configured to obtain a merge candidate list size value (N) and identify motion vector candidates to include in a merge candidate list having a list size equal to the merge candidate list size value. The merge candidate list may be a merge motion vector (MV) candidate list or a motion vector predictor (MVP) candidate list (also known as an AM VP candidate list). The processor generates the merge candidate list such that the merge candidate list includes the TMVP, regardless of the list size.

Abstract: A video coder may determine a motion vector of a non-adjacent block of a current picture of the video data. The non-adjacent block is non-adjacent to a current block of the current picture. Furthermore, the video coder determines, based on the motion vector of the non-adjacent block, a motion vector predictor (MVP) for the current block. The video coder may determine a motion vector of the current block. The video coder may also determine a predictive block based on the motion vector of the current block.
