摘要: An example device for presenting split-rendered media data includes a memory configured to store media data; and a processing system comprising one or more processors implemented in circuitry, the processing system being configured to: send pose information representing a predicted pose of a user at a first future time to a split rendering server; receive an at least partially rendered image for the first future time and data associating the pose information with the at least partially rendered image from the split rendering server; and at a second future time, present a rendered image based on the partially rendered image.

摘要: An example device for requesting a reduced resolution for video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: decode a first sequence of pictures of a bitstream, the first sequence of pictures having a first resolution; in response to determining that the device is to enter a power saving mode, send a message requesting a reduced resolution relative to the first resolution for a second sequence of pictures, the second sequence of pictures being subsequent to the first sequence of pictures in coding order; and decode the second sequence of pictures of the video data of the bitstream, the second sequence of pictures having the reduced resolution. The reduced resolution may be reduced spatial resolution, reduced temporal resolution (frame rate), or both.

摘要: Systems, methods, and computer-readable storage media are provided for decoded picture buffer (DPB) operations and rewriting access unit delimiters (AUDs) after bitstream extractions. An example method can include storing one or more pictures associated with an access unit (AU) in a decoded picture buffer (DPB), the AU including a first plurality of pictures, the first plurality of pictures corresponding to a plurality of video coding layers; after each picture of a second plurality of pictures associated with the AU is removed from a coded picture buffer (CPB), removing at least one picture of the one or more pictures from the DPB; and storing, in the DPB, each picture of the second plurality of pictures removed from the CPB.

摘要: Video encoders and video decoders are configured to supplemental enhancement information (SEI) messages. The SEI messages may include picture orientation transform type syntax elements that indicate how a picture may be rotated and/or mirrored. The SEI messages may also include quality metrics.

摘要: Example techniques and devices for decoding video data are disclosed. An example device includes memory configured to store the video data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to extract a current sub-picture from a bitstream of the video data and parse virtual boundary syntax elements indicative of virtual boundaries for a current picture, wherein the current sub-picture is associated with the current picture. The one or more processors are configured to update the virtual boundaries based at least in part on the virtual boundary syntax elements and decode the current sub-picture based on the updated virtual boundaries.

摘要: An example method includes decoding, from a coded video bitstream, a first syntax element that specifies a constraint for a second syntax element that specifies whether subpicture information is present in the coded video bitstream and whether more than one subpicture is allowed to be present in the coded video bitstream; and decoding, based on the constraint specified by the first syntax element, the second syntax element.

摘要: An example device for decoding video data, the device including a memory configured to store video data; and one or more processors implemented in circuitry and configured to: determine that adaptive loop filter (ALF) information can be present in a picture header of a picture of the video data and cannot be present in a slice header; in response to determining that the ALF information can be present in the picture header and cannot be present in the slice header, determine that a picture header syntax structure is not present in the slice header (e.g., without decoding data representing a value for a syntax element indicating whether the picture header syntax structure is present in the slice header); and decode the picture according to the determination that the picture header syntax structure is not present in the slice header.

摘要: A video decoder may be configured to output layers of video data according to layers specified in an output layer set mode as well as based on the actual layers received in an access unit. Accordingly, the video coder may be configured to output layers actually received rather than restart a video bitstream in situations where the layers actually received do not match the layers specified in the output layer set mode. In another example, a video encoder may disable inter prediction when the sub-picture ID of a sub-picture in a currently coded picture does not match the sub-picture ID of a sub-picture in a reference picture.
