Summary

At this point, you should have a basic understanding of how DirectShow works. DirectShow applications create filter graphs; these filter graphs are composed of filters connected to form a path from stream capture to the display or storage of a stream. Filters are independent, object-oriented modules that handle one specific function in the processing of a media stream: capture or display of a video image, playing a sound, and so on. Now that we ve covered these basic points, we ll begin to explore GraphEdit, a useful DirectShow application that allows you to create your own, fully functional filter graphs with just a few mouse clicks so that you can put these abstract concepts into practice.
