Claim 13:
14. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
perform a conversion between a video comprising a picture and a bitstream of the video,
wherein the bitstream conforms to a format rule,
wherein the format rule specifies that a first flag is present at a beginning of a picture header associated with the picture,
wherein the first flag indicates whether the picture is an intra random access point (IRAP) picture or a gradual decoding refresh (GDR) picture,
wherein the format rule further specifies that whether no_output_of_prior_pics_flag is present in the bitstream is based on an indication of the first flag,
wherein no_output_of_prior_pics_flag affects an output of previously-decoded pictures, and
wherein when a nal unit type syntax element of the picture is equal to at least one of IDR_W_RADL, IDR_N_LP, CRA_NUT, or GDR_NUT, the no_output_of_prior_pics_flag is present in the bitstream.
