Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.

Media streams from containers processed by hosted code

Interaction between an application, a user interface framework, and a graphics module to render a portion of an application surface. The application requests a surface corresponding to a particular range of the application surface from the user interface framework. In response, the user interface framework provides the requested ranged surface to the application. The application instructs the graphics module to populate the ranged surface by drawing into the ranged surface. The application then instructs the user interface framework to compose the ranged surface using the drawn ranged surface and other information available to the user interface framework. The user interface framework composing a composed surface using the drawn surface provided by the application, and additional information available to the user interface framework. The user interface framework may cache information from previously composed surface to allow for faster re-rendering should those portions later come into view on the display.

Application and user interface framework interaction

A style model implementation that is applied to objects within a user interface to define any attributes of the objects. The model is divided into two parts: a 'runtime' which uses a style definition to affect the look and feel of the user interface, and a 'design-time' which is the experience presented by WYSIWYG tools used to define the look and feel of the user interface. The design-time may be implemented in terms of the run-time objects. Properties associated with the styles can be set on the objects using the design-time UI and enforced at runtime. Styles may be grouped into themes to provide an easy mechanism to apply changes to many objects.
