Claim 10:
11. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
perform a conversion between a video comprising one or more pictures and a bitstream of the video,
wherein the bitstream conforms to a format rule,
wherein the format rule specifies whether a second flag is equal to zero or not is access unit (AU) specific, wherein the second flag is included in a picture timing (PT) supplemental enhancement information (SEI) message and indicates whether one or more syntax elements related to timing information are allowed to be present in the PT SEI message,
wherein when all pictures in an associated AU are random access skipped leading (RASL) pictures with a first flag equal to zero, the second flag is equal to zero, wherein the first flag equal to zero indicates each picture referring to a picture parameter set (PPS) has one or more video coding layer (VCL) network abstraction layer (NAL) units and the VCL NAL units are of a same type, and wherein the same type is only a RASL NAL unit type (NUT), and
wherein the first flag is a pps_mixed_nalu_types_in_pic_flag and the second flag is pt_cpb_alt_timing_info_present_flag.
