1. A method of video processing, comprising:
performing a conversion between a video and a bitstream of the video according to a first format rule and a third format rule,
wherein the bitstream comprises one or more layers comprising one or more network abstraction layer (NAL) units,
wherein the first format rule specifies that a first layer identifier of an end of sequence network abstraction layer (EOS NAL) unit is required to be equal to a second layer identifier of one of the one or more layers in the bitstream, and
wherein the third format rule specifies that a picture unit (PU) of a particular layer after an EOS NAL unit of the particular layer shall be an intra random access point (IRAP) PU or a gradual decoding refresh (GDR) PU.
