Abstract
Systems, methods and apparatus for processing visual media data are described. One example method includes performing a conversion between visual media data and a visual media file including one or more tracks storing one or more bitstreams of the visual media data according to a format rule; wherein the format rule specifies whether a first element indicative of whether a track contains a bitstream corresponding to a specific output layer set controls whether a second element indicative of a chroma format of the track and/or a third element indictive of a bit depth information of the track is included in a configuration record of the track.
Claims20
A method of processing visual media data, comprising:
- performing a conversion between visual media data and a visual media file including one or more tracks storing one or more bitstreams of the visual media data according to a format rule;
- wherein the format rule specifies whether a first element indicative of whether a track contains a bitstream corresponding to a specific output layer set controls whether a second element indicative of a chroma format of the track and/or a third element indictive of a bit depth information of the track is included in a configuration record of the track.
An apparatus of processing visual media data, comprising a processor configured to implement a method comprising:
- performing a conversion between visual media data and a visual media file including one or more tracks storing one or more bitstreams of the visual media data according to a format rule,
- wherein the format rule specifies a presence of a chroma format syntax element and/or a bit depth syntax element or a syntax constraint on the chroma format syntax element and/or the bit depth syntax element depending on (1) whether a track contains a specific bitstream corresponding to a specific output layer set and/or (2) whether a bitstream to which a configuration record applies is a multi-layer bitstream.
A non-transitory computer-readable recording medium storing instructions that cause a processor to:
- perform a conversion between visual media data and a visual media file including one or more tracks storing one or more bitstreams of the visual media data according to a format rule,
- wherein the format rule specifies a presence of a chroma format syntax element and/or a bit depth syntax element or a syntax constraint on the chroma format syntax element and/or the bit depth syntax element depending on (1) whether a track contains a specific bitstream corresponding to a specific output layer set and/or (2) whether a bitstream to which a configuration record applies is a multi-layer bitstream.
