Abstract
A mechanism for processing video data is disclosed. Information in a sequence parameter set (SPS) in a Versatile Video Coding (VVC) Common Media Application Format (CMAF) track is determined. A rule specifies a value of a video usability information progressive source flag (vui_progressive_source_flag) field in the SPS shall be equal to one. A conversion is performed between a visual media data and a media data file based on the SPS.
Claims20
A method for processing video data comprising:
- acquiring information in a sequence parameter set (SPS) in a Versatile Video Coding (VVC) Common Media Application Format (CMAF) track based on a rule, wherein the rule specifies a value of a video usability information progressive source flag (vui_progressive_source_flag) field in the SPS is constrained to be equal to one;
- and
- performing a conversion between a visual media data and a media data file based on the SPS,
- wherein the rule specifies a value of video usability information interlaces source flag (vui_interlaced_source_flag) field in the SPS is constrained to be equal to one.
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:
- acquire information in a sequence parameter set (SPS) in a Versatile Video Coding (VVC) Common Media Application Format (CMAF) track based on a rule, wherein the rule specifies a value of a video usability information progressive source flag (vui_progressive_source_flag) field in the SPS is constrained to be equal to one;
- and
- perform a conversion between a visual media data and a media data file based on the SPS,
- wherein the rule specifies a value of video usability information interlaces source flag (vui_interlaced_source_flag) field in the SPS is constrained to be shall-be-equal to one.
A non-transitory computer readable medium comprising a computer program product for use by a video coding device, the computer program product comprising computer executable instructions stored on the non-transitory computer readable medium such that when executed by a processor cause the video coding device to:
- acquire information in a sequence parameter set (SPS) in a Versatile Video Coding (VVC) Common Media Application Format (CMAF) track based on a rule, wherein the rule specifies a value of a video usability information progressive source flag (vui_progressive_source_flag) field in the SPS is constrained to be equal to one;
- and
- perform a conversion between a visual media data and a media data file based on the SPS,
- wherein the rule specifies a value of video usability information interlaces source flag (vui_interlaced_source_flag) field in the SPS is constrained to be shall-be-equal to one.
