1. A video processing method, comprising:
performing a conversion between a video comprising one or more pictures comprising one or more slices and a bitstream of the video,
wherein the bitstream conforms to a format rule,
wherein the format rule specifies that a flag in a picture header controls applicability of adaptive loop filtering of all slices in the picture,
wherein the format rule further specifies that a constraint on a syntax element included in the bitstream indicating a slice type of a slice of the one or more slices depends on a condition, and
wherein the condition is based on at least one of a general constraint flag, a network abstraction layer unit type, or whether the slice is in a first picture of an access unit.
