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 set of syntax elements comprising at least one of the following: a first syntax element identifying a first point cloud frame, a frame-specific attribute property being applied to the first point cloud frame, and the set of bits are indicated in the bitstream, or a second syntax element identifying a second point cloud frame, a frame boundary marker being applied to the second point cloud frame, wherein the length in bits of the second syntax element is greater than or equal to the number of bits in the set of bits.

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 general constraints information (GCI) for the video, the GCI comprising one or more syntax elements, wherein each of the one or more syntax elements is absent from the bitstream and has a value equal to a first predetermined value. Compared with the conventional solution, the proposed method can advantageously improve the coding efficiency.

Abstract: Embodiments of the present disclosure provide a solution for video streaming. A method for retrieving media data comprises: determining, by a first device, identity information for a target segment of a media representation from a manifest file, the target segment being specified as comprising one of the following: a concatenation of an initialization segment for the media representation and a media segment containing media data if the initialization segment is absent from the manifest file, or the media segment containing the media data if the initialization segment is present in the manifest file; and retrieving the target segment based on the identity information.

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 video and a bitstream of the video, wherein the media file comprises a data structure indicating video decoder initialization information (VDII) for decoding the bitstream, the data structure being at a level higher than a track level. Compared with the conventional solution, the VDII can be signaled more efficiently.

Abstract: Methods, systems and apparatus for video processing are described. One example video processing method includes performing a conversion between a video including a video region and a bitstream of the video according to a rule, wherein the rule specifies that an adaptive loop filtering operation is allowed for the video region in response to an absence of one or more adaptation parameter set (APS) network abstraction layer (NAL) units that include adaptive loop filtering data.

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 a first set of coded video data units representing a target picture-in-picture region in the first video, the first set of coded video data units being replaceable by a second set of coded video 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).
