1. A method for video decoding performed by at least one processor, the method comprising:
obtaining coded video data comprising a network abstraction layer (NAL) unit;
obtaining, from the coded video data, a syntax element indicating an access unit delimiter of the NAL unit;
determining whether the access unit delimiter indicates a slice type value of the NAL unit;
determining whether the access unit delimiter of the NAL unit indicates at least one of a video coding layer (VCL) value via a random access point (RAP) syntax;
determining access unit boundary values of the NAL unit according to whether the access unit delimiter syntax indicates the slice type value of the NAL unit or the at least one of the VCL value via the RAP syntax; and
decoding the video data based on the determined access unit boundary values.
