##Multiple Graphs in DirectShow Applications sometimes need to start and stop some filters independently of others, and to switch connections dynamically. GMFBridge is a multi-graph toolkit that shows how to use multiple DirectShow graphs to solve these problems. There are two example applications (in C++ and VB6)

In this article, Geraint Davies shows how to solve these problems using multiple, related graphs of filters. The accompanying source code includes GMFBridge: GMFPlay shows how to view multiple clips as a single movie, and GMFPreview demonstrates how to keep showing the preview stream from a video capture device while starting and stopping capture into different files.
