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.
摘要翻译：描述媒体处理方法，系统和应用程序接口（API）。在一个实施例中，媒体引擎组件（也称为媒体引擎）提供了简单而统一的方式，可以将媒体从原始到目的地呈现，而不需要关于底层组件及其连接性和管理的亲密知识。媒体引擎的客户不必担心如何渲染特定的媒体，而只能专注于要呈现的媒体以及媒体的播放位置。在至少一个实施例中，媒体会话被提供并由媒体引擎封装，并且提供了一种机制，通过该机制使附加组件对于应用是透明的，并且在至少一些实施例中是媒体引擎。在一些实施例中，媒体引擎和媒体会话提供用于构建，配置和操纵组件流水线（例如，媒体源，变换和汇点）的简单API，用于在源和一个或多个目的地之间的媒体流控制。

摘要： Techniques for playing a media file in a multimedia application include launching a multimedia application as one process and automatically launching a pipeline of one or more media processing components as one or more isolated processes. In this manner, any untrustworthy components can be executed in an isolated process that is separate from the execution process of the multimedia application, thereby improving fault tolerance and hang resistance.

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.
摘要翻译：多媒体处理系统和方法通过将数据流信息与维持多媒体组件的流状态分开来提供灵活性和模块化。该系统包括用于处理接收到的媒体数据的媒体处理器组件，用于确定用于执行媒体处理的事件的时间线的媒体会话，以及拓扑加载器组件来加载描述所接收的媒体数据的流的拓扑，以便能够经由媒体对象的可扩展符号抽象。拓扑加载器确保拓扑中描述的事件发生。该系统还包括诸如媒体接收器组件的核心层组件，以确定用于从多媒体处理系统输出的媒体流和耦合到供应媒体数据进行处理的媒体源组件。在系统中创建的拓扑符号地提供数据流信息，与维护控制信息的流状态无关。
