摘要: Compositing functionality is provided in the form of an application program interface (API) that applications can utilize to composite images on video data that is to be rendered. In at least some embodiments, this functionality is exposed in a multimedia pipeline towards the end of the multimedia pipeline, such as at or by a renderer component. A set of methods exposed by the API permit an application to create and manage image compositing.

摘要: Strategies for automatically selecting the most appropriate processing pipeline (or runtime) for a particular data item are described. In one embodiment, a media playing application automatically selects the most appropriate media processing pipeline for a media data item from multiple available processing pipelines, or candidates. In this regard, the application makes this selection by utilizing heuristic techniques to identify which available pipeline provides the most enhanced playback experience to a user with respect to certain attributes such as supported playback features and security. These heuristic techniques can take one or more criteria into account and can be implemented in any suitable way. By way of example and not limitation, in one embodiment, a selection process is used wherein potential pipeline candidates are ordered and sequentially evaluated.
