Abstract
Systems, methods and apparatus for generating or parsing a visual media file according to a file format include performing a conversion between a visual media data and a visual media file that stores a bitstream of the visual media data according to a format rule. The visual media file stores multiple tracks that belong to an entity group of a specific type. The format rule specifies that, responsive to the multiple tracks having a track reference to a particular type to a group identifier, the multiple tracks (A) omit carrying a sample group of a specific type or (B) carry the sample group of the specific type such that information in the sample group of the specific type is consistent with that in the entity group of the specific type.
Claims20
A visual media processing method, comprising:
- performing a conversion between a visual media data and a visual media file that stores a bitstream of the visual media data according to a format rule;
- wherein the visual media file stores multiple tracks that belong to an entity group of a specific type, and
- wherein the format rule specifies that, responsive to the multiple tracks having a track reference to a particular type to a group identifier, the multiple tracks (A) omit carrying a sample group of a specific type or (B) carry the sample group of the specific type such that information in the sample group of the specific type is consistent with that in the entity group of the specific type.
An apparatus comprising a processor configured to implement a visual media processing method, comprising:
- performing a conversion between a visual media data and a visual media file that stores a bitstream of the visual media data according to a format rule;
- wherein the visual media file stores multiple tracks that belong to an entity group of a specific type, and
- wherein the format rule specifies that, responsive to the multiple tracks having a track reference to a particular type to a group identifier, the multiple tracks (A) omit carrying a sample group of a specific type or (B) carry the sample group of the specific type such that information in the sample group of the specific type is consistent with that in the entity group of the specific type.
A computer-readable storage medium having code stored thereon;
- the code, upon execution by a processor, causing the processor to implement a visual media processing method, comprising:
- performing a conversion between a visual media data and a visual media file that stores a bitstream of the visual media data according to a format rule;
- wherein the visual media file stores multiple tracks that belong to an entity group of a specific type, and
- wherein the format rule specifies that, responsive to the multiple tracks having a track reference to a particular type to a group identifier, the multiple tracks (A) omit carrying a sample group of a specific type or (B) carry the sample group of the specific type such that information in the sample group of the specific type is consistent with that in the entity group of the specific type.
