    Abstract: In one example, a video coding device is configured to intra-predict a block of video data, using values of pixels along a primary boundary of the block, to form a predicted block, determine whether to filter the predicted block using data of a secondary boundary of the block, and filter the predicted block using data of the secondary boundary in response to determining to filter the predicted block. The video coding device may determine whether to filter the predicted block based on a comparison of a Laplacian value or a gradient difference value to a threshold. The determination of whether to filter the predicted block may be based at least in part on a boundary relationship, e.g., the relationship of one boundary to another, or of a boundary to pixel values of the predicted block.

    Abstract: In one example, a method for encoding video data includes determining a first value for a line of a first plurality of lines, wherein the first plurality of lines are perpendicular to a first edge of a block of the video data; in response to determining that the value satisfies at least one threshold: determining a second value for the line of the first plurality of lines; and determining a second value for a line of a second plurality of lines, wherein the second plurality of lines are perpendicular to a second edge of the block of video data; determining, based on the second value for the line of the first plurality of lines and the second value for the line of the second plurality of lines, an average value; and determining, based on the average value, whether or not to encode one or more deblocking parameter offsets.

    Abstract: This disclosure describes techniques for performing sample adaptive offset signaling and coding in a video coding process. Techniques of the disclosure include both a merge-based and prediction-based signaling process for sample adaptive offset information (i.e., offset values and offset type). The techniques includes determining offset information for a current partition, comparing the offset information of the current partition with offset information of one or more neighbor partitions, coding a merge instruction in the case that the offset information of one of the one or more neighbor partitions is the same as the offset information of the current partition, and coding one of a plurality of prediction instructions in the case that the offset information of the one or more neighbor partitions is not the same as the offset information of the current partition.
