## VFW Video Capture

The Video Capture filter is installed with the DirectShow run time. If you have video capture hardware that uses Video For Windows, this filter is available in the Filter Graph Editor when you choose Insert Filters from the Graph menu, under the Video Capture Sources.

Unlike ordinary DirectShow filters, special category filters, such as Video Capture Source filters, can work with more than one device. When DirectShow is installed, it will look for devices installed on your computer that work with the special category filter and list the options in that category. For example, in the Video Capture Source filter category, DirectShow will list all the video capture cards installed on the system. You then need to choose which device to use.

The Video for Windows Video Capture filter has two output pins called Capture and Preview.

The filter supports the IAMVfwCaptureDialogs interface.

The capture output pin supports the IAMStreamConfig, IAMVideoCompression, and IAMDroppedFrames interfaces.
