Abstract: Methods, apparatus, and systems for dynamically indicating a playout group in various scenarios are disclosed. In one example aspect, a method includes determining a playout group corresponding to a volumetric video in a three-dimensional space based on a playout group information, the playout group including a plurality of components, wherein each component of a certain type has a version that is different from another component of the certain type, obtaining a two-dimensional volumetric video content from a media track corresponding to the playout group, and reconstructing the volumetric video into a three-dimensional space based on the plurality of components with different versions.
