摘要:
This document describes techniques for, and apparatuses capable of, provider-specific parsing for content retrieval. In one embodiment, a user's computing device receives code (e.g., an executable script) from a content provider and utilizes a parsing scheme associated with the content provider to parse the code and determine an address that can be used to retrieve an instance of content. The instance of content can then be retrieved using the address and without executing the code. In some embodiments, the parsing scheme is specific to the content provider and can be updated based on a change to the code.
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:
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.

Systems and methods for resolving a partial topology are disclosed. In one embodiment a media engine includes a topology loader module that receives a partial topology from another module associated with the media engine. The topology loader implements logic operations that convert a partial topology into a full topology, which may be returned to the media engine for presentation of the media stream(s) to a user.

Audio data having M channels includes a header with metadata specifying a conversion function for converting the M channels of digital audio data into N channels of data. The metadata is a string of coefficients, which may be specified by the content author, to define to conversion of the M channels of digital audio data into N channels.
摘要:
Methods for streaming web content data via a computer-readable medium. The web content data comprises one or more media samples. The media samples are encoded in a streaming media format as a web component stream. The web component stream is combined with other component streams comprising additional data other than web content data into a presentation stream. The presentation stream is transmitted via a media server to a client. Rendering commands, which are included in one or more rendering samples encoded in the web component stream along with the media samples, coordinate synchronization between the media samples and the additional data when the client renders the presentation stream.

The subject disclosure is directed towards a technology in which a mobile device service plays background audio as instructed by a third party audio player application. The service continues to play background audio after the audio player application is deactivated from the foreground, e.g., as another application becomes the foreground application. Also described is launching agents to obtain additional information and/or to handle custom audio formats, and handling of user requests from a universal (system) volume control or the audio player application (when in the foreground).
