Summary

In this chapter, we ve covered the Sample Grabber from both the application side that is, the use of the Sample Grabber to provide access to the media stream in your own DirectShow applications and the Sample Grabber architecture. The design of the Sample Grabber is unusual, but it casts a lot of light on the internal design of DirectShow, the filter graph, and filters. With the Grabber Sample, you ve begun to explore how application and filter come together in a synergistic way. Now we ll move on to a source filter and learn how media samples are created.
