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 comprising one or more pictures comprising one or more slices and a bitstream of the video. The bitstream conforms to a predefined order between a position of a first NAL (network abstraction layer) unit in a picture unit carrying an adaptation parameter set information and a second NAL unit that is a last video coding layer (VCL) NAL unit in the picture unit.

Abstract: A mechanism for processing video data is disclosed. A description of Cross Random Access Point Referencing (CRR) samples is signaled in a visual media data file in International Organization for Standardization (ISO) base media file format (ISOBMFF). A conversion is performed between a visual media data and the visual media data file based on the CRR sample group.

Abstract: A mechanism for processing video data is disclosed. Video decoder initialization information is signaled between an encoder to a decoder. The video decoder initialization information contains a range of initialization parameters. A conversion is performed between a visual media data and a visual media data file based on the range of initialization parameters.

Abstract: A method includes performing a conversion between a video including video pictures that include one or more subpictures and a bitstream of the video. The bitstream conforms to a format rule specifying that one or more syntax structures are constrained based on a constraint flag of a syntax element that includes general constraints information.

Abstract: Methods, devices and systems for signaling the use of subpictures in coded video pictures are described. One example method of video processing includes performing a conversion between a video and a bitstream of a video, wherein the bitstream conforms to a format rule, wherein the format rule specifies that a first syntax element signaled in a sequence parameter set (SPS) of the bitstream is indicative of a length of identifiers of subpictures in the SPS, and wherein the signaling of the first syntax element is independent of a value of a second syntax element that is indicative of explicit signaling of the identifiers of the subpictures in the SPS or a picture parameter set (PPS).

Abstract: A method for video processing is described. The method includes performing a conversion between a video including one or more pictures including one or more subpictures including one or more slices and a bitstream representation of the video according to a rule, and wherein the bitstream representation includes a number of coded units, wherein the rule specifies that a decoding order of coded units within a subpicture is in an increasing order of subpicture level slice index values of the coded units.

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.
