DSGrab - Command Line DirectShow Image Capture tool
DSGrab is a command line DirectShow Image Capture tool. It will capture a single still image from a compatible capture device (e.g. web cam, tuner card, etc.) and save it as a file to the disk. The primary purpose of the application is to create a "live cam" feed on a web site by using it in conjuction with the built in Windows Task Scheduler, a manipulator tool such as ImageMagik, and an FTP tool such as WinSCP. It is also (probably) the least amount of code you could write to interact with the DirectShow APIs.
