Abstract
A mechanism for processing video data is disclosed. The mechanism includes determining to infer that a value of a syntax element is equal to 0 when the syntax element is not present in a bitstream. The value of the syntax element plus one specifies a number of submeshes in each mesh frame. A conversion is performed between a visual media data and a bitstream based on the syntax element.
Claims20
A method for processing media data, comprising:
- performing a conversion between a visual media data and a bitstream according to a format rule,
- wherein the format rule specifies that a first syntax element is conditionally included in the bitstream, and a value of the first syntax element plus a particular value specifies a number of bits used to represent a second syntax element specifying a submesh identifier (ID), when present.
An apparatus for processing video data comprising:
- a processor;
- and
- a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- perform a conversion between a visual media data and a bitstream according to a format rule,
- wherein the format rule specifies that a first syntax element is conditionally included in the bitstream, and a value of the first syntax element plus a particular value specifies a number of bits used to represent a second syntax element specifying a submesh identifier (ID), when present.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- generating the bitstream for visual media data according to a format rule,
- wherein the format rule specifies that a first syntax element is conditionally included in the bitstream, and a value of the first syntax element plus a particular value specifies a number of bits used to represent a second syntax element specifying a submesh identifier (ID), when present.
