Create professional-quality media applications and components with Microsoft Media Foundation—and deliver the next generation of high-definition multimedia. With this hands-on book, you’ll learn how to build applications to capture video and audio files of different types, process media information, and stream it over the Internet. If you program with C++ and the Component Object Model (COM), this book is ideal—especially for developers looking to transfer their skills from Microsoft DirectShow®.

Discover how to:

• Construct media pipelines with individual Media Foundation components
• Build a simple video player to see how a basic media session works
• Create applications that transcode media content from one format to another
• Process data streams by writing Media Foundation Transform objects
• Examine the internal architecture of Media Foundation Sources and Sinks
• Design a custom media session object to learn advanced Media Foundation concepts
• Create image overlays on top of video and send the result over the network
