Create and develop multimedia or rich content based on the Windows Media SDK and components like Advanced Systems Format (ASF) file container, Windows audio and video codecs, streamable objects and DRM handling. Reads the metadata in ASF and MP3 files.

The Windows Media Format SDK provides application developers with access to the components of the Windows Media Format. These components include the Advanced Systems Format (ASF) file container, the Windows Media Audio and Video codecs, basic network streaming capability, and digital rights management.

The objects of the Windows Media Format SDK manipulate the components of Windows Media at a low level; the other components of the Windows Media SDK include objects that work on a higher level.

The primary purpose of the Windows Media Format SDK is to enable developers to create applications that play, write, edit, encrypt, and deliver Advanced Systems Format (ASF) files and network streams. These files and streams commonly contain audio and video content encoded using the Windows Media Audio and Video codecs. However, ASF can contain any type of data.

Main features:

- Support for industry-leading codecs. The Windows Media Format 11 SDK includes the Microsoft Windows Media Video 9 codec and the Microsoft Windows Media Audio 9.1 codec. Both of these codecs provide exceptional encoding of digital media content. New for this release is the Windows Media Video 9 Advanced Profile codec, which provides optimizations for broadcast video. This SDK also includes the Microsoft Windows Media Video 9 Screen codec for compressing computer-screen activity during sessions of user applications, and the Windows Media Audio 9.1 Voice codec, which encodes low-complexity audio such as speech and intelligently adapts to more complex audio such as music, for superior representation of combined voice-music scenarios.
- Support for writing ASF files. Files are created based on customizable profiles, enabling easy configuration and standardization of files. This SDK can be used to write files in excess of 2 gigabytes, enabling longer, better-quality, continuous files.
- Support for reading ASF files. This SDK provides support for reading local ASF files as well as reading ASF data being streamed over a network. Support is also provided for many advanced reading features, such as native support for multiple bit rate (MBR) files, which contain multiple streams with the same content encoded at different bit rates. The reader automatically selects which MBR stream to use, depending upon available bandwidth at the time of playback.
- Support for delivering ASF streams over a network. This SDK provides support for delivering ASF data through HTTP to remote computers on a network, and also for delivering data directly to a remote Windows Media server.
- Support for editing metadata in ASF files. Information about a file and its content is easily manipulated with this SDK. Developers can use the robust system of metadata attributes included in the SDK, or create custom attributes to suit their needs.
- Support for content editing applications. This SDK enables applications to seek to points within a file by presentation time and by video frame. In addition, files created by using the Windows Media Format SDK can maintain timestamps in formats used in film and television production.
- Support for reading and editing metadata in MP3 files. This SDK provides integrated support for reading MP3 files with the same methods used to read ASF files. Applications built with the Windows Media Format SDK can also edit metadata attributes in MP3 files using built-in support for the most common ID3 tags used by content creators.
- Support for Digital Rights Management protection. This SDK provides methods for reading and writing ASF files and network streams that are protected by Digital Rights Management to prevent unauthorized playback or copying of the content.

Windows Media Format SDK - a neat, useful tool that provides developers access to the components of the Windows Media Format.
