摘要： 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.

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.

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.

摘要： Methods and systems enable content authors to achieve frame-accurate editing and, in at least some embodiments, reduce the amount of content that needs to be decompressed in order to operate on the frames. Some embodiments ensure that bit rate integrity is preserved so that bit rate conditions associated with streaming environments are preserved. Various embodiments intelligently determine which content portions should be decompressed, processed, and recompressed and which content portions should not be decompressed.

摘要： Various embodiments related to the performance of gapless audio playback of two or more audio tracks are provided. One disclosed embodiment provides a method of performing gapless audio playback comprising rendering a plurality of samples of a current audio track via a current filter graph, and notifying an end-of-stream soon event via a current filter graph. Upon detecting the end-of-stream soon event, a next filter graph corresponding to a next audio track is pre-rolled and then paused. An end-of-stream event is notified at the current filter graph signaling an end of the current audio track. Then, upon detecting an end-of-stream event, the next filter graph is signaled to begin rendering samples of the next audio track.
