Abstract: An apparatus configured to code video information includes a memory and a processor in communication with the memory. The memory is configured to store video information associated with a bitstream. The apparatus further includes a processor in communication with the memory, the processor configured to determine whether a reference layer is included in the bitstream. The processor is further configured to determine an indication of one or more parameters for a decoded picture buffer based upon whether the reference layer is included in the bitstream and to code the video information based at least in part on the determined indication of the one or more parameters for the decoded picture buffer.

Abstract: A device comprising a video file creation module is configured to obtain a plurality of slices of coded video content. Parameter sets are associated with the coded video content. The video creation module encapsulates the plurality of slices of coded video content within one or more access units of a video stream. A first type of parameter set may be encapsulated within one or more access units of the video stream. A second type of parameter set may be encapsulated within a sample description. The sample description may include an indicator identifying a number of parameter sets stored within one or more access units of the video stream.

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 to extract a motion constrained tile sets (MCTS) sub-bitstream from an original bitstream including the video data based at least in part on information of an MCTS extraction information set (MCTS-EIS) supplemental enhancement information (SEI) message; and in response to determining to extract the MCTS sub-bitstream, omit all SEI network abstraction layer (NAL) units that contain non-MCTS-nested SEI messages from inclusion in the extracted MCTS sub-bitstream, regardless of a value of a NAL unit header layer identifier value for the non-MCTS-nested SEI messages.

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 example method for encoding or decoding video data includes storing, by a video coder and in a reference picture buffer, a version of a current picture of the video data, including the current picture in a reference picture list (RPL) used to predict the current picture, and coding, by the video coder and based on the RPL, a block of video data in the current picture based on a predictor block of video data included in the version of the current picture stored in the reference picture buffer.

Abstract: A device for determining information for video data includes one or more processors implemented in circuitry that are configured to determine one or more most-interested regions of a plurality of regions of an image of video data based on data representative of the one or more most-interested regions. The data representative of the one or more most-interested regions is external to video coding layer (VCL) data of a bitstream including the video data. The processors output a request for relatively high-quality video data for the one or more most-interested regions of the image and output, after outputting the request for the relatively high-quality video data, a request for relatively low-quality video data for one or more other regions of the image.
