1. A method for video decoding, the method comprising:
obtaining video data;
parsing a video parameter set (VPS) syntax of the video data, wherein the VPS syntax specifies, for a respective layer of the video data, whether (i) the respective layer does not use inter-layer prediction or (ii) the respective layer may use inter-layer prediction;
determining whether a value of a sequence parameter set (SPS) syntax element indicates a picture order count (POC) value of an access unit (AU) of the video data based on the VPS syntax;
setting at least one of a plurality of pictures and slices of the video data to the AU based on the VPS syntax; and
setting, in response to determining that the VPS syntax comprises a predetermined value of a flag, an input picture size of the at least one of the pictures to a coded picture size signaled in SPS of the video data.
