Abstract
The present invention concerns a method of encapsulating subpicture bitstreams in at least one media file, the subpicture bitstreams corresponding to encoded media data of a subpicture corresponding to a rectangular region of video data, the method comprising: obtaining the plurality of subpicture bitstreams; encapsulating each subpicture bitstream in a subpicture track; generating at least one base track referencing at least two subpicture tracks and forming a spatial arrangement of the at least two subpicture tracks; generating information describing APS referenced by samples of the at least two subpicture tracks; encapsulating the subpicture tracks, the at least one base track and the information describing APS in the at least one media file.
