Abstract
Methods, devices, and systems for configuring different access units in scalable video coding are described. In one example aspect, a method of video processing include performing a conversion between a video having one or more pictures in one or more video layers and a bitstream of a video. The bitstream includes a coded video sequence that has one or more access units. The bitstream further includes a first syntax element indicating whether an access unit includes a picture for each video layer making up the coded video sequence.
Claims20
A method of video processing, comprising:
- performing a conversion between a video comprising one or more pictures in one or more video layers and a bitstream of the video,
- wherein the bitstream comprises a coded video sequence that includes an access unit, and
- wherein the bitstream conforms to a format rule that specifies that each picture in the access unit carries a layer identifier that is equal to a layer identifier of one of pictures present in a first access unit of the coded video sequence.
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 video comprising one or more pictures in one or more video layers and a bitstream of the video,
- wherein the bitstream comprises a coded video sequence that includes an access unit, and
- wherein the bitstream conforms to a format rule that specifies that each picture in the access unit carries a layer identifier that is equal to a layer identifier of one of pictures present in a first access unit of the coded video sequence.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- perform a conversion between a video comprising one or more pictures in one or more video layers and a bitstream of the video,
- wherein the bitstream comprises a coded video sequence that includes an access unit, and
- wherein the bitstream conforms to a format rule that specifies that each picture in the access unit carries a layer identifier that is equal to a layer identifier of one of pictures present in a first access unit of the coded video sequence.
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 of the video comprising one or more pictures in one or more video layers,
- wherein the bitstream comprises a coded video sequence that includes an access unit, and
- wherein the bitstream conforms to a format rule that specifies that each picture in the access unit carries a layer identifier that is equal to a layer identifier of one of pictures present in a first access unit of the coded video sequence.
