Abstract: The techniques of this disclosure are generally related to parallel coding of video units that reside along rows or columns of blocks in largest coding units. For example, the techniques include removing intra-prediction dependencies between two video units in different rows or columns to allow for parallel coding of rows or columns of the video units.

Abstract: A method includes receiving, at a device, a plurality of image frames corresponding to a video stream. The plurality of image frames include a first image frame having a first resolution and a second image frame having a second resolution that is lower than the first resolution. The method also includes detecting, at the device, a trigger by analyzing the second image frame. The method further includes designating, at the device, the first image frame as an action frame based on the trigger.

Abstract: An apparatus configured to filter video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores video information comprising at least two adjacent video blocks, each video block comprising a plurality of video samples, and each video sample having a bit depth. The processor determines a filtered video sample based at least in part on a video sample and an adjustment value. The processor determines the adjustment value at least in part from an input with a limited bit depth. The input is determined from a set of one or more video samples, and its bit depth is limited such that it is less than the bit depth of the one or more video samples.

Abstract: Techniques for performing sample adaptive offset (SAO) and adaptive loop filter (ALF) processes in a video coding process are described. The SAO and ALF processes may be combined. In one example, the determination of offset values for a SAO filter process may be based on classifications used in an ALF process. In one example, an ALF classification that indicates a particular directional characteristic of a video block may be used to determine how and whether an SAO filter process is applied to each sample within the video block.
