1. A method of processing visual media data, comprising:
performing a conversion between a visual media file and a bitstream of a visual media data according to a format rule,
wherein the format rule specifies a characteristic of a syntax element in the visual media file,
wherein the syntax element has a value that is indicative of a number of bytes used for indicating a constraint information associated with the bitstream,
wherein the format rule specifies that the syntax element specifies the number of bytes in a general constraint information syntax element in the visual media file and is coded in the visual media file using N bits, and wherein N is specified to be only equal to six,
wherein a track in the visual media file comprises a video bitstream comprising one or more output layer sets,
wherein the format rule specifies that a first bit with a particular bit index in the general constraint information syntax element corresponds to a second bit with the particular bit index in all general constraint information syntax structures in all profile tier level syntax structures to which the one or more output layer sets conform, and
wherein the format rule specifies that the first bit is set to one only if the second bit in all general constraint information syntax structures is set equal to one.
