DirectShow Dump Filter

Overview

This filter allows, when added to a DirectShow graph, any audio or video stream to be dumped to disk. It can take the place of an audio or video renderer. Using a Tee filter, it can dump a stream from any intermediate filter in the graph. It's typical use is in conversion graphs. Care is taken to preserve the presentation time stamps, even when running faster than the indicated playback speed.

For integration in commercial applications ask for the HDTV Filter SDK.
