Abstract: Embodiments of the present disclosure relate to multimedia processing method, apparatus, device and medium, wherein the method includes: presenting a first multimedia interface comprising first content; receiving an interface switching request of a user in the first multimedia interface; and switching from the first multimedia interface currently presented to a second multimedia interface, and presenting second content in the second multimedia interface, wherein the first content comprises the second content and other content associated with the second content, and the second content comprises a target audio and a target subtitle corresponding to the target audio.

Abstract: Disclosed are a subgraph matching strategy determining method, a subgraph matching method, a counting method, and a device; the matching strategy determining method includes: obtaining a pattern; generating a plurality of restriction sets, for the pattern, each restriction set being capable of eliminating all other automorphisms different from the pattern per se in the automorphisms of the pattern; obtaining a plurality of search order schedules, for the pattern; combining the plurality of restriction sets and the plurality of search order schedules, each combination being referred to as a configuration; using a performance prediction model to predict a computation amount of a subgraph matching algorithm corresponding to each configuration, and determining one or more configurations as a subgraph matching strategy, based on the predicted computation amount.

Abstract: Disclosed in embodiments of the present disclosure are a communication method and apparatus, and an electronic device. A specific implementation of the method comprises: in response to a call initiation operation of a multimedia conference, determining a candidate object of the multimedia conference according to an object targeted by the call initiation operation; and displaying, on a multimedia conference interface of the multimedia conference, call state information for the candidate object.

Abstract: Methods for rowgroup consolidation with delta accumulation and versioning in distributed systems are performed. The systems provide performant methods of row storage that enable versioned modifications of data while keeping and allowing access to older versions of the data for point-in-time transactions. The accumulation of valid rows, deletes, and modifications is maintained in blobs for rowgroups until a size threshold is reached, at which point the rows are moved into a columnar compressed form. Changes to data and associated metadata are stored locally and globally via appends, maintaining logical consistency. Metadata is stored in footers of files allowing faster access to the metadata and its associated data for transactions and instant rollback via metadata version flipping for aborted transactions, as well as lock-free reads of data.
