  • Publication number: 20250106400
    Abstract: A mechanism for processing visual media data is disclosed. An extended dependent random access point (EDRAP) sample is determined. The EDRAP sample is a sample for which all subsequent samples in both decoding and output order can be correctly decoded provided that required preceding streaming access point (SAP) or EDRAP samples are available for referencing when decoding the EDRAP sample and the subsequent samples. A conversion is performed between a visual media data and a media data file based on the EDRAP sample.

  • Publication number: 20250088646
    Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of sub-pictures associated with a picture and a flag. The sub-pictures are contained in a plurality of video coding layer (VCL) network abstraction layer (NAL) units. A NAL unit type value is the same for all VCL NAL units associated with the picture when the flag is set to a first value. When the flag is set to a second value, a first NAL unit type value for VCL NAL units containing one or more of the sub-pictures of the picture is different than a second NAL unit type value for VCL NAL units containing one or more of the sub-pictures of the picture. The sub-pictures are decoded based on the NAL unit type values. The sub-pictures are forwarded for display as part of a decoded video sequence.
