Abstract
Methods, systems, and devices for signaling picture information in access units in video bitstream processing are disclosed. An example method of video processing includes performing a conversion between a video comprising one or more pictures and a bitstream of the video. The bitstream conforms to a format rule, which specifies that a flag and a syntax element, when included in the bitstream, are access unit (AU) specific. The flag indicates, in response to a current AU not being a first AU in the bitstream in a decoding order, whether a nominal coded picture buffer (CPB) removal time of the current AU is determined relative to (a) a nominal CPB removal time of a previous AU associated with a buffering period supplemental enhancement information (SEI) message, or (b) a nominal CPB removal time of the current AU.
