    Abstract: Systems, methods, and devices are disclosed that encode video, decode video, or both. These systems, methods, and devices generate and/or receive an enable syntax element in an encoded bitstream, wherein the enable syntax element indicates whether a loop filter is turned on or turned off for a group of video blocks. They also generate or receive one or more additional syntax elements identifying parameters for the loop filter for the group of video blocks in response to the enable syntax element indicating the loop filter is turned on for the group of video blocks. These systems, methods, and devices also perform the loop filter for the group of video blocks based on the received enable syntax element.

    Abstract: A video coding device configured according to some aspects of this disclosure includes a memory configured to store a plurality of motion vector candidates. Each motion vector candidate can corresponding to at least one of a plurality of prediction units (PUs) partitioned in a parallel motion estimation region (MER). The video coding device also includes a processor in communication with the memory. The processor is configured to select a subset of the plurality of motion vector candidates to include in a merge candidate list. The selection can be based on a priority level of each motion vector candidate. The processor can be further configured to generate the merge candidate list to include the selected motion vector candidates.

    Abstract: An example method includes determining a respective variance value for pixels of each respective sub-block of at least four sub-blocks of a current block of video data of a particular block size; determining an average of the determined variance values for the at least four sub-blocks; determining a maximum difference value for the current block based on the average and the variance values for the at least four sub-blocks; determining whether pixels of the current block are homogeneous based on whether the maximum difference value for the current block satisfies a threshold difference value; and in response to determining that the pixels of the current block are homogeneous, selectively including block sizes that are greater than or equal to a threshold block size in a sub-set of block sizes to evaluate for use when intra encoding the pixels of the current block.
