For more information, see Kernel Streaming Proxy Plug-ins. Thank you for posting on the Intel Communities. Windows driver documentation is an open source project. You can provide plug-ins without altering existing minidriver binaries. These are COM interfaces that provide methods to access property values.

Providing a unified kernel streaming class model for both audio and video minidrivers. AVStream Simulated Hardware Sample Driver (Avshws), Windows 8.1. Requiring minidriver writers to produce less code. The sample demonstrates how to write a filter-centric AVStream minidriver. DirectX 9.0 contains updates for AVStream, kernel streaming components, and stream class.ĪVStream offers significant advantages to the vendor by: If you build on an operating system earlier than Windows XP, make sure that you use the latest available DirectX Driver Development Kit (DDK). Microsoft supports the stream class driver only for existing minidrivers.ĪVStream drivers build on Microsoft Windows XP, Microsoft Windows Server 2003, or any platform Windows 98 Gold or later version that has DirectX 8.0 or later version installed. Audio vendors should write minidrivers that run under Portcls.sys. The preferred class driver for audio drivers is the Microsoft-provided audio port class driver. Hardware vendors write minidrivers that run under Ks.sys. Microsoft provides AVStream as part of the operating system, in the export driver Ks.sys. AVStream is a Microsoft-provided multimedia class driver that supports video-only streaming and integrated audio/video streaming.
