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 current video block of a video and a bitstream of the video based on a first syntax element, wherein the first syntax element specifies the number of additional general constraints information (GCI) bits in a syntax structure for general constraints information other than at least one second syntax element, the at least one second syntax element is used for byte-alignment of the syntax structure, and a value of the first syntax element is allowed to be equal to 6.

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 current point cloud sample of a point cloud sequence and a bitstream of the point cloud sequence, wherein during the conversion at least one of the following data units comprises an integer number of bytes: a first data unit indicating an end of a point cloud frame associated with the current point cloud sample, a second data unit comprising attribute values for a single attribute in the current point cloud sample, or a third data unit specifying a single attribute value for all points in the current point cloud sample. Thereby, the proposed method can advantageously better support the encapsulation of data units in the type-length-value (TLV) bytestream format.

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 each media sample in an external stream representation (ESR) in the media presentation corresponds to a media sample in a main stream representation (MSR) in the media presentation, a presentation time of the media sample in the ESR being the same as a presentation time of the corresponding media sample in the MSR. Thereby, 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 method for video processing. The method comprises: performing a conversion between a target video block of a video and a bitstream of the video based on a general profile indicator of a profile defining capabilities for decoding the bitstream, wherein at least two bits of the general profile indicator are combined to indicate a bit depth for the profile.

Abstract: Embodiments of the present disclosure provide a solution for media data transmission. A method for media data transmission is proposed. The method comprises: receiving, at a first device, a metadata file from a second device; and determining, from the metadata file, an indication for indicating whether a first set of coded video data units representing a target picture-in-picture region in a first video is replaceable by a second set of coded video data units in a second video.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: receiving, by a first device, a metadata file from a server; and determining, from the metadata file, a list of region identities (IDs) for indicating a first set of coded video data units in each picture of a first video representing a target picture-in-picture region which is able to be replaced by a second set of coded video units in a second video.

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 an external stream track comprising a set of samples, a sample entry type of a sample entry for the set of samples is encapsulated based on a restricted scheme, the sample entry comprises an indication associated with the restricted scheme, and a value of the indication indicates that a sample in the set of samples is allowed to contain more than one coded picture of the external stream track.

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 the bitstream when at least one condition applies. The at least one condition comprises a first condition that the bitstream is indicated to conform to at least one second profile. The first profile corresponds to a first bit depth and a first relative sample rate of color components of video samples. The at least one second profile corresponds to a second bit depth different from the first bit depth and a second relative sample rate of color components of video samples, which is the same as the first relative sample rate.
