Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises determining, during a conversion between a target video block of a video and a bitstream of the video, a prediction of the target video block from a buffer set. The target video block is coded with intra block copy (IBC) mode. The method further comprises performing the conversion based on the prediction. Compared with the conventional solution, the proposed method can advantageously improve the IBC buffer design and thus improve the coding effectiveness and coding efficiency.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: obtaining, during a conversion between a target video block of a video and a bitstream of the video, prediction information of a target subblock in the target video block based on types of predicted samples in the target subblock, the target video block being coded by a geometric partitioning tool; and performing the conversion based on the prediction information of the target subblock.

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: Techniques for video processing, including video coding, video decoding and video transcoding are described. One example method includes performing a conversion between a video picture that includes one or more tiles and one or more rectangular slices and a bitstream of the video according to a rule. The rule specifies that, for iteratively determining information about the one or more rectangular slices, a variable indicating a tile index is updated only for slices having indices that are smaller than a value equal to a number of slices in the video picture minus 1.

Abstract: Various methods are provided for programmatically providing a platform for responding dynamically providing a response to a property level availability call through API request based on run-time information. One example method may comprise receiving the property level availability call, the property level availability call configured to elicit a response identifying an availability of one or more of the plurality of specified properties for a specified time frame, determining, based on an associated bid, whether an affirmative response to the property level availability call is profitable, and in an instance in which the affirmative response is profitable, causing transmission of the affirmative response.

Abstract: Embodiments of the present disclosure provide a solution for video processing. A method for video processing is proposed. The method comprises: determining, during a conversion between a target block of a video and a bitstream of the video, first motion information of a plurality of geometric partitions of the target block based on a geometric partitioning mode (GPM) with motion vector differences (GMVD); and performing the conversion between the target block and the bitstream based on the first motion information, the bitstream including a first set of indications of GMVD information associated with the target block. Compared with the conventional solution, the proposed method can advantageously improve the encoding/decoding efficiency.

Abstract: A method for video processing is provided to include: performing a conversion between a current video block of a video and a coded representation of current video block, wherein the conversion uses a coding mode in which the current video block is constructed based on a first domain and a second domain and/or chroma residue is scaled in a luma-dependent manner, and wherein information used for the coding mode is signaled in a parameter set that is different from a sequence parameter set (SPS), a video parameter set (VPS), a picture parameter set (PPS), or an adaptation parameter set (APS) used for carrying adaptive loop filtering (ALF) parameters.
