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: A multimedia processing system and methods provide flexibility and modularity by separating data flow information from maintaining of stream state for multimedia components. The system includes a media processor component to process received media data, a media session to determine a timeline for events to occur for performing media processing and a topology loader component to load a topology that describes a flow for the received media data to enable processing via an extensible symbolic abstraction of media objects. The topology loader ensures that events described in the topology occur. The system also includes core layer components such as media sink components to determine a media stream for output from the multimedia processing system and a media source component coupled to supply media data for processing. The topology created in the system symbolically provides data flow information, independent of maintaining a streaming state of control information.

摘要: A computing system, which is in communication with a multimedia source and that includes at least one application for processing multimedia content from the multimedia source, includes an Application Programming Interface (API) for obtaining basic multimedia information that may be required by applications to process the multimedia content. By doing this, the invention enables multimedia application(s) to easily obtain the basic information from the API in a predetermined and standard manner, without having to obtain the information directly from the multimedia source, thereby reducing the functionality that has to be programmed directly into the application(s) for obtaining the basic information, and thereby reducing the cost, time, and resources that are required for creating the multimedia application(s).

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.
