6. An apparatus comprising:
at least one processor; and
at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
parse a mixed network abstraction layer unit type pictures sample group used to merge video base tracks having a subpicture track;
parse a sample group description entry of the mixed network abstraction layer unit type pictures sample group, the sample group description entry indicating a group of pairs of mixed network abstraction layer unit type track reference indices, which reference video subpicture tracks or track groups; and
wherein when a video bitstream is resolved from a video base track containing a mixed network abstraction layer unit type sample group with merging pairs of video subpicture tracks signaled in a mixed network abstraction layer unit type pictures sample group entry, then there is mixing of different network abstraction layer unit types.
