Microsoft
Media Foundation for Windows Phone

Applies to: Windows Phone 8 Developer
Preview only

 

Microsoft
Media Foundation (MF) is a framework for audio and video capture and playback
for the desktop. Microsoft Media Foundation for Windows Phone is a
reimplementation of a subset of the MF APIs. This feature enables Windows Phone
8 Developer Preview apps to implement the following scenarios.

• Rendering video to textures in
  apps that use native code.
• Displaying cinematics for
  games.
• Playing in-game background
  audio in apps that use native code, such as a game soundtrack.

 

XAML and
Direct3D apps for Windows Phone

 

Applies to: Windows Phone 8 Developer Preview only

 

With Windows Phone 8 Developer Preview, you
can use Direct3D to render graphics that are displayed behind or inline with
XAML controls and content. With the DrawingSurfaceBackgroundGrid control, your
graphics are displayed across the entire screen, below any other XAML elements
on the page, including any elements in the frame. With the DrawingSurface
control, you can choose an area of the screen to draw on. The size and layout
of your drawing surface are handled just as they are with other XAML controls. Both
of these controls require your application to create a Windows Phone Runtime
component defining a class that implements an interface, either
IDrawingSurfaceBackgroundContentProvider or IDrawingSurfaceCOntentProvider, and
hosts the actual Direct3D drawing code. To receive touch input, your class must
also implement IDrawingSurfaceManipulationHost.
