Abstract: A media timeline is described. In an implementation, a method includes receiving a request from an application at an application programming interface (API) to interact with a plurality of media. Based on the request, a media timeline is generated. The media timeline is for exposure via the API to the application and includes a plurality of nodes. The media timeline defines a presentation of a first media referenced by a first node with respect to a second media referenced by a second node.

Abstract: 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 used 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.

Abstract: 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.

Abstract: Incorporating interactive media into a playlist allows for media, operable to play automatically without a prompt after being loaded, to be loaded into a playlist and played from the playlist without overlapping playback with other media in the playlist. Incorporating interactive media into a playlist involves employing a playlist, a media wrapper, a media control, and a media player to preroll media, immediately stop playing the prerolled media while other media is playing, signal that media has finished playing in order to seamlessly begin playing the next media in the playlist.

Abstract: 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.
