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： A set of interfaces and data structures (i.e., a demultiplexer API) for representing a demultiplexer of multimedia data is presented. The data structure utilizes a number of fields, each containing an element of a command. In one embodiment, at least seven commands are formed for proper operation of the demultiplexer, including Initialize, SetPresentationDescriptor, GetPresentationDescriptor, GetPendingPresentationDescriptor, ProcessInput, ProcessOutput, and Flush commands. The demultiplexer API allows the consumer to use muxed stream data such as DV in a uniform manner to generate elementary stream data such as audio and video (compressed or uncompressed) and allows demultiplexers to be used as an independent component.
摘要翻译：提出了一组用于表示多媒体数据的解复用器的接口和数据结构（即解复用器API）。数据结构使用多个字段，每个字段都包含命令的元素。在一个实施例中，形成用于解复用器的正确操作的至少七个命令，包括Initialize，SetPresentationDescriptor，GetPresentationDescriptor，GetPendingPresentationDescriptor，ProcessInput，ProcessOutput和Flush命令。解复用器API允许消费者以均匀的方式使用诸如DV的多路复用数据流数据来生成诸如音频和视频（压缩或未压缩）的基本流数据，并且允许解复用器被用作独立的组件。

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).
