Abstract: A video processing method includes performing a conversion between a video and a bitstream of the video. The bitstream conforms to a format rule specifying a condition that controls whether or how one or more syntax elements related to picture order counts for a long term reference picture are included in a reference picture list syntax structure in the bitstream.

Abstract: Non-power-two-partition tree in video compression is described. In an exemplary aspect, a method for video processing includes determining, for a conversion between a first block of video and a bitstream representation of the first block of video, whether a use of non-power-of-two partition trees (NPT-T) is enabled or disabled, wherein the NPT-T includes splitting the first block to multiple smaller sized child blocks of the first block, and at least one child block's width and/or height have a dimension that is a non-power-of-two integer; and performing the conversion based on the NPT-T in response to the determination that the NPT-T is enabled.

Abstract: A method includes performing a conversion between a block of a video and a bitstream of the video according to a rule. The rule specifies that whether a syntax element identifying a deblocking offset for a chroma component of the video is included in a video region level is determined based on a colour format of the video.

Abstract: Methods, devices and systems for configuring different access units in scalable video coding are described. In one example aspect, a method of video processing include performing a conversion between a video comprising one or more pictures in one or more video layers and a bitstream of a video, wherein the bitstream comprises a coded video sequence that includes one or more access units, and wherein the bitstream further comprises a first syntax element indicating whether an access unit includes a picture for each video layer making up the coded video sequence.

Abstract: A method of video processing includes making a first determination about whether a decoder-side motion vector refinement (DMVR) tool is enabled for a conversion between a current block of a current picture of a video and a coded representation of the video; making a second determination, based on the first determination, about whether or how to clip a motion vector according to a bounding block for reference sample padding in a reference picture used for determining a prediction block for the current block according to a rule, and performing the conversion based on the first determination and the second determination. By using the DMVR tool, an encoded motion vector from the coded representation is refined prior to using for determining the prediction block.

Abstract: A mail processing method and apparatus, a device, a medium, a computer program product, and a computer program provided in the present disclosure, where the method includes: receiving a to-be-sent mail; obtaining, if it is identified that the to-be-sent mail includes an instant messaging group identifier, a group mail address corresponding to the instant messaging group identifier; and taking the group mail address as a recipient address and performing a sending operation on the to-be-sent mail. In the present disclosure, in a case of receiving, by a mail server, a mail sent by a mail client, if it is identified that the recipient includes an instant messaging group name, the mail is sent to a group address corresponding to the group name, which improves functional integration of email and IM software, thereby providing richer collaborative office functions.

Abstract: A video processing method includes determining, for a conversion between a current block of a video and a bitstream representation of the video, whether to enable a level mapping operation or a level remapping operation based on a rule, wherein the level mapping operation or the level remapping operation includes changing between a first representation of a residual coefficient of the current block and a second representation of the residual coefficient of the current block based on neighboring residual coefficients of the residual coefficient; and performing the conversion by selectively using the level mapping operation or the level remapping operation based on the determining.

Abstract: Systems, methods and apparatus for video processing are described. The video processing may include video encoding, video decoding, or video transcoding. One example method of video processing includes performing a conversion between a video including one or more video regions and a bitstream of the video according to a format rule. The format rule specifies that a variable X indicates whether B slice is allowed or used in a video region. The format rule further specifies that the variable X is based on values of a reference picture list information present flag and/or a field indicating a number of entries in a reference picture list syntax structure.
