Designing Hardware and Drivers for the Microsoft® Windows® Family of Operating Systems

Digital Video Camcorder Support in Windows


This article describes how developers of PC video-editing applications can call certain Microsoft® DirectShow® application programming interfaces to control a digital video (DV) camcorder device connected to a PC running the Microsoft® Windows® operating system. This paper also recommends a mechanism to preserve application performance while the camcorder performs time-consuming operations. The information in this paper applies to for Windows 98 SE, Windows Millennium Edition, Windows 2000, and Windows XP.

Note: Msdv.sys is a kernel streaming minidriver that utilizes the system-supplied streaming class driver, Stream.sys, to control a DV camcorder device. For documentation about writing kernel streaming minidrivers, see "Streaming Devices" in the Windows DDK.
