Abstract: Embodiments of the present disclosure provide a solution for video processing. The method comprises: performing a conversion between a target video block of a video and a bitstream of the video according to a decoding conformance constraint. The decoding conformance constraint specifies that a decoder conforming to a first profile is capable of decoding of at least a first picture of the bitstream when at least one condition applies, the at least one condition comprising a first condition that the bitstream is indicated to conform to at least one second profile. The first profile comprises a Still Picture profile corresponding to a first bit depth higher than a predefined value, and the at least one second profile comprises at least one non-Still Picture profile corresponding to at least one second bit depth.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: performing a conversion between a bitstream of a video and a media file of the video, wherein a first data structure in the media file comprises a first indication and at least one second data structure describing a preselection in the media file, and the first indication is signaled before the set of second data structures and specifies the number of non-alternative tracks grouped by a preselection track group for the preselection.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: performing a conversion between a bitstream of a video and a media file of the video, wherein the media file comprises a group of labels comprising a first label, a first indication in a first data structure for the first label is coded with a single bit, and the first indication indicates whether the first label contains a summary label for the group of labels.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: receiving, at a first device, a metadata file from a second device; and determining a descriptor in a data set in the metadata file, a presence of the descriptor indicating that a representation in the data set is a main stream representation (MSR).

Abstract: Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: performing a conversion between a point cloud sequence and a bitstream of the point cloud sequence based on a tile inventory, the tile inventory being valid starting from a first coded point cloud frame in the bitstream, the first coded point cloud frame immediately following a data unit for the tile inventory in a bitstream order, or the first coded point cloud frame following the data unit in the bitstream order and having a frame counter partially indicated in the data unit. Thereby, the proposed method can advantageously better support the application of the tile inventory.

Abstract: Embodiments of the present disclosure provide a solution for media processing. A method for media processing is proposed. The method comprises: performing a conversion between a media file of a media and a media presentation of the media, wherein the media presentation comprises a main stream representation (MSR) and an external stream representation (ESR) associated with the MSR, a concatenation of a first segment in the ESR, a second segment in the MSR corresponding to the first segment, and subsequent segments following the second segment in the MSR results in a file conforming to a file format standard. Compared with the conventional solution, the proposed method can advantageously support the extended dependent random access point (EDRAP)-based technology more efficiently.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing comprises: performing a conversion between a media file of a first video and a bitstream of the first video, wherein the media file comprises an indication indicating that a first track carrying the bitstream of the first video and a second track carrying a bitstream of a second video are a track pair for providing a picture-in-picture service. The proposed method advantageously makes it possible to support picture-in-picture services in a media file based on ISO base media file format (ISOBMFF).

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing comprises: performing a conversion between a media file of a first video and a bitstream of the first video, wherein the media file comprises a first indication indicating whether a first set of coded video data units representing a target picture-in-picture region in the first video are replaceable by a second set of coded video data units associated with a second video. The proposed method advantageously makes it possible to support picture-in-picture services in a media file based on ISO base media file format (ISOBMFF).

Abstract: Methods, systems, and apparatus for video processing are described. One example video processing method includes performing a conversion between a video comprising a luma block and a bitstream of the video according to a rule. The rule specifies that whether a slice header (SH) includes a first syntax element is based on a second syntax element. The first syntax element indicates whether use of a delta quantization parameter (QP) is enabled for one or more coding units (CUs) of a specific slice of the luma block.
