Abstract: A video coding device, such as a video decoder, may be configured to decode a buffering period supplemental enhancement information (SEI) message associated with an access unit (AU). The video decoder is further configured to decode a duration between coded picture buffer (CPB) removal time of a first decoding unit (DU) in the AU and CPB removal time of a second DU from the buffering period SEI message, wherein the AU has a TemporalId equal to 0. The video decoder is configured to determine a removal time of the first DU based at least in part on the decoded duration and decode video data of the first DU based at least in part on the removal time.

Abstract: A video coding device, such as a video encoder or a video decoder, may be configured to decode a sequence level flag to determine the presence of one or more sub-picture level coded picture buffer (CPB) parameters for a decoding unit (DU) of an access unit (AU) in either in a picture timing supplemental enhancement information (SEI) message or a sub-picture timing SEI message associated with the DU. The coding device may also decode the one or more sub-picture level CPB parameters from the picture timing SEI message or the sub-picture timing SEI message based on the sequence level flag.

Abstract: Various techniques for enhanced support of stream adaptation and splicing based on clean random access (CRA) pictures are described. Instead of using a flag in the slice header to indicate that a broken link picture is present, a distinct network abstraction layer (NAL) unit type can be used to indicate the presence of a broken link picture. In some implementations, a first distinct NAL unit type may be used to indicate the presence of a broken link picture with leading pictures, while a second distinct NAL unit type indicates the presence of a broken link picture without leading pictures. In some implementations, a third distinct NAL unit type may be used to indicate the presence of a broken link picture with decodable leading pictures.

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 a dedicated array for parameter sets.

Abstract: A video encoder signals whether WPP is used to encode a picture of a sequence of video picture. If WPP is used to encode the picture, the video encoder generates a coded slice NAL unit that includes a plurality of sub-streams, each of which includes a consecutive series of bits that represents one encoded row of coding tree blocks (CTBs) in a slice of the picture. A video decoder receives a bitstream that includes the coded slice NAL unit. Furthermore, the video decoder may determine, based on a syntax element in the bitstream, that the slice is encoded using WPP and may decode the slice using WPP.

Abstract: A video encoder generates, based on a reference picture set of a current view component, a reference picture list for the current view component. The reference picture set includes an inter-view reference picture set. The video encoder encodes the current view component based at least in part on one or more reference pictures in the reference picture list. In addition, the video encoder generates a bitstream that includes syntax elements indicating the reference picture set of the current view component. A video decoder parses, from the bitstream, syntax elements indicating the reference picture set of the current view component. The video decoder generates, based on the reference picture set, the reference picture list for the current view component. In addition, the video decoder decodes at least a portion of the current view component based on one or more reference pictures in the reference picture list.

Abstract: A video coder can be configured to code a syntax element that indicates if a loop filtering operation, such as deblocking filtering, adaptive loop filtering, or sample adaptive offset filtering, is allowed across a tile boundary. A first value for the syntax element may indicate loop filtering is allowed across the tile boundary, and a second value for the syntax element may indicate loop filtering is not allowed across the tile boundary. If loop filtering is allowed across a tile boundary, additional syntax elements may indicate specifically for which boundaries loop filtering is allowed or disallowed.
