1. A method of processing video data, the method comprising:
receiving a picture that includes a plurality of subpictures; and
decoding a quality metrics supplemental enhancement information (SEI) message associated with the plurality of subpictures of the picture, the quality metrics SEI message including:
a first syntax element indicative of a number of subpictures within the plurality of subpictures,
a quality metric type syntax element, associated with at least one subpicture of the plurality of subpictures, set to a first value among a plurality of values that respectively indicate a plurality of types of quality metrics, where the first value is set to 0, and
a quality metric syntax element specifying a second value;
determining that the quality metric type syntax element is set to 0;
based on the determination that the quality metric type syntax element is set to 0, determining to interpret the second value specified by the quality metric syntax element as a value indicative of a peak signal-to-noise ratio (PSNR) associated with the at least one subpicture; and
deriving, based on the second value specified by the quality metric syntax element, a derived PSNR associated with the at least one subpicture.
