    摘要: A system and methods provide handling of variable rate playback in a multimedia computer architecture. The systems and methods provide data structures and interfaces that enable a computer architecture and components therein with the ability to playback data at speeds faster and slower than real-time, to playback data in reverse, and to change the rate of playback at any point during playback. One embodiment is a method for providing low-latency, glitch-free changes in a multimedia architecture. Other embodiments are directed to defining multimedia component responsibilities for making rate changes, allowing rate changes to work with standard playback types, coder-decoders, and renderers. The methods include determining a minimum of the maximum reported playback rates and determining minimum and maximum playback rates in a set of modes including: reverse skip mode, reverse key frame mode, reverse full mode, forward full mode, forward key frame mode, and forward skip mode.

    摘要: A method and system provides interfaces, data structures and events for representing a “sink” of multimedia data to interact with objects in a multimedia system to control multimedia objects. The interfaces and data structures enable efficient management for media objects that must interface directly with each other. One embodiment is directed to providing a common interface and a single API to a plurality of media objects. In an embodiment, the API is a control layer that isolates the media objects from each other and provides a single point of control, allowing media objects to be added or removed without affecting any other media objects. The control layer allows users to become familiar with only one API instead of many thereby facilitating the tasks of programming and documentation.

    摘要: Media processing methods, systems and application program interfaces (APIs) are described. In but one embodiment, a media engine component, also referred to as a media engine, provides a simple and unified way of rendering media from an origin to a destination of choice without requiring intimate knowledge about the underlying components, their connectivity and management. Clients of the media engine need not worry about how to render the particular media, but rather can simply focus on what media to render and where to render the media. In at least one embodiment, a media session is provided and is encapsulated by the media engine and provides a mechanism by which additional components are made transparent to the application and, in at least some embodiment, the media engine. In some embodiments, the media engine and media session provide a simple API for building, configuring, and manipulating a pipeline of components (e.g. media sources, transforms, and sinks) for media flow control between an origin and one or more destinations.

    摘要: Media processing methods, systems and application program interfaces (APIs) in which a destination component, also referred to as a destination, provides an application with a simple and unified way of rendering, archiving, broadcasting (or other types of media output processing) media from an origin to a target of choice, without requiring the application to have intimate knowledge about underlying components, their connectivity and management. For example, applications can use a destination to help manage the rendering or archiving (or other processing) of the particular media.

    摘要: Techniques enable locating a position within a file that corresponds to a desired seek time without having access to an index specifying the desired seek time's position. An iterative process may be used to estimate the position that corresponds to the desired seek time. The process may iterate through multiple estimations until a difference between a time corresponding to an estimated position and the desired seek time is within an acceptable amount or until the process reaches an iteration threshold. The file may then be played beginning at or near the desired seek time. The techniques may therefore allow a user to seek within a file while the user progressively downloads or streams the file.
