As you can see from DSRender and DSBuild, it s not difficult to construct DirectShow applications with lots of functionality. The definitions and interfaces for the DirectShow objects are straightforward and easy to use. It s this ease of use that makes DirectShow so powerful. In just a little more than 20 lines of code, you can build a fully functioning media player. All you need after that is user interface. That said, application programming for graphical user interfaces is time-consuming and generally takes more effort than the core of the application itself. Either of these examples can be dropped right into an existing Windows application pretty much as they are to provide broad media capabilities, although you would probably want to change the function names. Now, with the programming basics out of the way, we can move on to specific topics of interest, starting with the foundations of audio recording and playback.
