1. A method of video coding, executable by a processor, the method comprising:
receiving video data comprising one or more subpictures, the video data including a flag, signaled in a sequence parameter set, indicating whether to use a network abstraction unit (NAL) layer identifier as a subpicture identifier, where the subpicture identifier is signaled in a NAL unit header based on the flag indicating to use the NAL layer identifier, and the subpicture identifier is signaled in a slice header based on the flag indicating not to use the NAL layer identifier; and
decoding the video data based on the subpicture identifier,
wherein a length of the subpicture identifier is signaled by the sequence parameter set.
