Abstract: Systems, methods and apparatus for storing or parsing a visual media file according 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 one or more tracks comprising one or more video layers. The format rule specifies that whether a first set of syntax elements indicative of layer dependency information is stored in the visual media file is dependent on whether a second syntax element indicating that all layers in the visual media file are independent has a value 1.

Abstract: Systems, methods and apparatus for encoding or decoding a file format that stores one or more images are described. One example method includes performing a conversion between a visual media file and a bitstream of a visual media data according to a format rule, where the format rule specifies a condition that controls whether an information item is included in a non-video coding layer track of the visual media file, and where a presence of the non-video coding layer track in the visual media file is indicated by a specific track reference in a video coding layer track of the visual media file.

Abstract: Systems, methods and apparatus for encoding or decoding a file format that stores one or more images are described. One example method includes performing a conversion between a visual media file and a bitstream of a visual media data according to a format rule, where the format rule specifies that a type of a sample entry determines whether decoding capability information network abstraction layer units are included in either the sample entry of a video track in the visual media file or in a sample of the video track and the sample entry of the video track in the visual media file.

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.

Abstract: Systems, methods and apparatus for processing image data are described. One example method includes performing a conversion between a visual media file and a bitstream. The visual media file comprises image items each comprising a sequence of one or more pictures according to a media file format, and the bitstream comprises access units each comprising one or more pictures each belonging to a layer according to a video coding format. The video coding format defines multiple profiles. The media file format specifies that the bitstream is represented in a file having a specific brand, and that one or more profiles used for representing the video in the bitstream are agnostic of the specific brand.
