Abstract: Systems, methods and apparatus for video processing are described. The video processing may include video encoding, video decoding, or video transcoding. One example method of video processing includes performing a conversion between a video and a bitstream of the video according to a format rule. The format rule specifies that a first field at a sequence level or a picture level or a slice level controls a value of a second field in an adaptation parameter set.

Abstract: A method implemented by a video coding apparatus. The method includes determining that a scalability dimension information (SDI) supplemental enhancement information (SEI) message precedes a multiview acquisition information (MAI) SEI message in decoding order whenever an access unit (AU) contains both the SDI SEI message and the MAI SEI message; and performing a conversion between a video and a bitstream of the video based on the SDI SEI message and the MAI SEI message. A corresponding video coding apparatus and non-transitory computer readable medium are also disclosed.

Abstract: A method implemented by a video coding apparatus. The method includes inferring a scalability dimension information (SDI) auxiliary identifier (ID) is equal to a first value when an SDI auxiliary information flag is equal to the first value; and performing a conversion between a video and a bitstream of the video based on the value inferred. A corresponding video coding apparatus and non-transitory computer readable medium are also disclosed.

Abstract: A method includes performing a conversion between a video including a video picture and a bitstream of the video according to a rule, wherein the video picture including a subpicture, a tile, and a slice, and wherein the rule specifies that, due to the subpicture including the slice that is partitioned from the tile, the conversion is performed by refraining from counting a height of the subpicture using a number of tiles of the video picture.

Abstract: A method includes making a determination, according to a rule, about whether a height of a subpicture of a video picture of a video is less than a height of a tile row of the video picture; and performing, using the determination, a conversion between the video and a bitstream of the video.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data and a visual media data file. The visual media data file includes pictures in layers, a random access recovery point (roll) sample group specifying access points into the layers, and a grouping type parameter. The grouping type parameter specifies a correspondence between the access points and relevant layers of the layers. The grouping type parameter includes a layer identifier method identification code parameter specifying that the access points include one or more of: one or more gradual decoding refresh (GDR) pictures; and one or more mixed network abstraction layer (NAL) unit pictures with both an intra random access point (IRAP) subpicture and a non-IRAP subpicture.

Abstract: Systems, methods and apparatus for encoding, decoding or transcoding digital video are described. One example method of video processing includes performing a conversion between a video and a bitstream of the video including multiple layers, wherein the bitstream includes a plurality of supplemental enhancement information, SEI, messages associated with an access unit, AU, or a decoding unit, DU, of a particular output layer set, OLS, or a particular layer, wherein the plurality of SEI messages, including a message type different from scalable nesting type, is based on a format rule, and wherein the format rule specifies that each of the plurality of SEI messages has a same SEI payload content due to the plurality of SEI messages being associated with the AU or the DU of the particular OLS or the particular layer.

Abstract: A mechanism for processing video data is disclosed. A conversion is performed between a visual media data and a media data file based on one or more extended dependent random access point (EDRAP) samples. Each EDRAP sample shall be a first sample in segment or a subsegment of a main stream representation (MSR).

Abstract: A method of video processing includes performing a conversion between a video including one or more scalable video layers and a bitstream of the video. The video includes one or more video pictures including one or more slices. The bitstream conforms to a format rule. The format rule specifies that a value of a field indicative of a slice type of a slice is set to indicate a type of intra slice in case that a corresponding network abstraction layer unit type is in a predetermined range and that a corresponding video layer flag indicates that a video layer containing the slice does not use inter-layer prediction.
