    Abstract: Devices, systems and methods for digital video coding, which includes matrix-based intra prediction methods for video coding, are described. In a representative aspect, a method for video processing includes performing a conversion between a current video block of a video and a bitstream representation of the current video block according to a rule, where the rule specifies a relationship between samples of the current video block and matrices or offset values applied in a matrix weighted intra prediction (MIP) mode during the conversion, and where the MIP mode includes determining a prediction block of the current video block by performing, on previously coded samples of the video, a boundary downsampling operation, followed by a matrix vector multiplication operation, and selectively followed by an upsampling operation.

    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: Methods, apparatuses and computer program products for implementing dynamic retry of a resource service in a network system are provided. An example method may include: transmitting a first service request to the resource service, determining a first service availability indicator, calculating a first service availability estimate associated with the resource service based on the first service availability indicator, and determining whether to transmit a second service request based on the first service availability estimate. The example method may be repeated by an example apparatus continuously for each transmitted service request.

    Abstract: A vertically integrated retail system includes an embedded storefront adapted to operate in a distributed manner through independent units embedded in different web sites or content in other host applications. Each unit of the embedded storefront enables a user to purchase goods, services, or other entities without leaving the host application. The units are modules that may be inserted into a web page, application, game, or other electronic media. Units can include product content such as video or animation, images, text, audio, music, or any other type of interactive or non-interactive electronic content. A user may receive virtual currency, virtual goods (such as virtual items or enhancements within a game application), or other rewards for completing transactions using the unit in the host application. Units may be embedded in host content via hyperlinks included in the content or through an application programming interface of a host content provider.

    Abstract: Methods, systems and devices for using end of sequence indications are described. An example method of video processing includes performing a conversion between a video and a bitstream of the video, wherein the bitstream includes multiple layers in multiple access units, AUs, including one or more pictures according to a format rule, wherein the format rule specifies that, responsive to an end of sequence (EOS) network abstraction layer (NAL) unit for a first layer being present in a first access unit (AU) in the bitstream, a subsequent picture of each of one or more higher layers of the first layer in an AU following the first AU in the bitstream is a coded layer video sequence start (CLVSS) picture.
