Abstract: In an example, a method of coding video data includes coding one or more non-video coding layer (VCL) network abstraction layer (NAL) units of a layer of a multi-layer bitstream, where the one or more non-VCL NAL units contain a decoded picture hash SEI message. The method also includes determining a set of layers of the multi-layer bitstream to which the decoded picture hash SEI message is applicable based on a layer identifier of the one or more non-VCL NAL units containing the decoded picture hash SEI message.

Abstract: In general, techniques are described for separately processing depth and texture components of video data. A device configured to process video data including a view component comprised of a depth component and a texture component may perform various aspects of the techniques. The device may comprise a processor configured to determine a supplemental enhancement information message that applies when processing the view component of the video data, and determine a nested supplemental enhancement information message that applies in addition to the supplemental enhancement information message when processing the depth component of the view component.

Abstract: A method of coding video data includes receiving video information associated with a first layer and a second layer and determining whether at least one of the first layer and the second layer is a default layer. The method can include at least partially restricting inter-layer prediction when neither the first layer nor the second layer is the default layer. A default layer can be a base layer or an enhancement layer. A flag can be received that indicates that inter-layer prediction is to be restricted. In addition, the method can include determining whether inter-layer prediction is allowed for the video information associated with the first layer, and determining whether inter-layer prediction is partially allowed for the video information associated with the second layer such that motion compensation is not used with the second layer video information.

Abstract: An apparatus configured to code video information in a bitstream includes a memory and a processor in communication with the memory. The memory is configured to store video information associated with a first layer including a first picture and a second layer including a second picture, the first picture associated with a current access unit (AU). The processor is configured to determine whether the current AU satisfies a first condition associated with the first layer, and based on a determination that the current AU does not satisfy the first condition associated with the first layer, determine whether a difference between a highest picture order count (POC) and a lowest POC of a plurality of pictures in a decoded picture buffer (DPB) is less than a threshold value. The processor may encode or decode the video information in the bitstream.

Abstract: An apparatus for encoding video information according to certain aspects includes a memory and computing hardware. The memory is configured to store video information. The computing hardware is configured to determine a bit depth of one or more view identifiers to signal, wherein each of the one or more view identifiers is associated with a layer to be encoded. The computing hardware is further configured to signal the bit depth of the one or more view identifiers in a bitstream.

Abstract: An example device for processing video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to determine a value of a syntax element of a temporal motion constrained tile sets (MCTS) supplemental enhancement information (SEI) message of an access unit, wherein the value of the syntax element represents whether all tiles of one or more corresponding pictures are included in separate MCTSs; and when the value of the syntax element indicates that the tiles of the corresponding pictures are not included in the separate MCTSs, set an MCTS identifier of the MCTS of a current picture of the access unit equal to a value of an index of the MCTS, the current picture being one of the corresponding pictures.

Abstract: An apparatus obtains an operation point reference track in the file and one or more additional tracks in the file. No operation point information sample group is signaled in any of the additional tracks. For each respective sample of each respective additional track of the one or more additional tracks, the apparatus determines whether to consider the respective sample part of the operation point information sample group. Based on the operation point reference track not containing a sample that is temporally collocated with the respective sample in the respective additional track, the respective sample in the respective additional track is considered part of an operation point information sample group of the last sample in the operation point reference track before the respective sample of the respective additional track.

Abstract: In an example, a method of decoding video data includes decoding, from a video parameter set (VPS) of a multi-layer bitstream, data that indicates at least one of a tile configuration for layers of the multi-layer bitstream or a parallel processing configuration for layers of the multi-layer bitstream. The method also includes decoding the multi-layer bitstream in accordance with the data decoded from the VPS.
