    Abstract: A method includes performing a conversion between a video including at least one video picture and a bitstream of the video according to a rule, wherein the at least one video picture includes one or more slices and one or more subpictures, and wherein the rule specifies that an order of slice indices of the one or more slices in the at least one video picture is indicated responsive to a syntax element associated with the at least one picture indicative of whether a single slice is included per subpicture of the at least one video picture.

    Abstract: Methods, apparatus, systems for video processing, including video encoding or video decoding are described. One example method includes performing a conversion between a video comprising a video picture that includes a video slice and a bitstream of the video. The bitstream conforms to a format rule specifying that, in case a slice type of the video slice is type P and temporal motion vector prediction is enabled, usage of reference picture resampling (RPR) for a reference picture in a collocated reference picture list is disabled. The reference picture is indicated by a reference index of a collocated picture of the video slice used for the temporal motion vector prediction.

    Abstract: A method of video processing includes performing a conversion between a video and a bitstream of the video according to a rule, wherein the rule specifies that a sub-bitstream extraction process is implemented to generate a sub-bitstream for decoding, wherein the sub-bitstream extraction process is configured to extract, from the bitstream, a sub-bitstream with a target highest temporal identifier, and wherein, the rule specifies that, during the extracting, upon removing a video coding layer (VCL) network abstraction layer (NAL) unit, filler data units and filler supplemental enhancement information (SEI) messages in SEI NAL units that are associated with the VCL NAL unit are also removed.

    Abstract: A method of video processing includes performing a conversion between a video including a picture and a bitstream of the video, wherein the bitstream conforms to a format rule, wherein the format rule specifies that an indication of whether a first flag is signalled at a beginning of a picture header associated with the picture, wherein the first flag is indicative of whether the picture is an intra random access point (IRAP) picture or a gradual decoding refresh (GDR) picture.
