Description: a sample WDM stream class video capture driver that supports two IEEE 1394 digital cameras.
The same driver may be able to support other digital cameras that conform to 1394-based Digital Camera Specification from 1394 Trade Association.
Digital camera supported by dcam.sys is a data source that produces digital image data without any other input connection. It manifests itself in a DirectShow graph as a WDM Streaming Capture Device and as a capture filter that has output capture stream supporting image sizes of 320x240 with a UYVY color space. Its de-compressor, Msyuv.dll, is part of the OS delivery, and it can convert image data format from UYVY to RGB16, RGB8, or to a Direct Draw surface if the video card supports UYVY format. -a sample WDM stream class video capture driver that supports two IEEE 1394 digital cameras.The same driver may be able to support other digital cameras that conform to 1394-based Digital Camera Specification from 1394 Trade Association.Digital camera supported by dcam.sys is a data source that produces digital image data without any other input connection.

Description: 基于DirectShow+WMF SDK的
媒体广播应用
基于DirectShow+WMF SDK实现的媒体广播应用采用了两种开发平台———VS2005与BCB,利
用VS2005作Filter的底层开发,其中涉及视音频的采集、编码以及把编码后的媒体流进行广播 借助
BCB的组装控件特性构造Graph模型,将各Filter模块连接起来并协同工作,通过以上方式运用Direct-
Show+WMF SDK技术成功实现了媒体广播。
-This paper presents media broadcasting applications using two kinds of development platform-
VS2005 andThe BCB. The Filters, whose foundationalmodulewas exploitedwithVS2005, have involved the
collection and encoding of the video and audio, and the broadcasting of the encoded media stream. Through
constructingGraphmodules by BCB components, the Filters inter-related each other andworked together. U-
sing such skills and based on DirectShow and WMF_SDK technology, the application has realized media
broadcast successfully and effectively.

Description: DirectShow是微软公司在ActiveMovie和Video for Windows的基础上推出的新一代基于COM(Component Object Model)的流媒体处理的开发包，与DirectX开发包一起发布。DirectShow使用一种叫Filter Graph的模型来管理整个数据流的处理过程，运用DirectShow，我们可以很方便地从支持WDM驱动模型的采集卡上捕获数据，并且进行相应的后期处理乃至存储到文件中。这样使在多媒体数据库管理系统(MDBMS)中多媒体数据的存取变得更加方便。它广泛地支持各种媒体格式，包括Asf、Mpeg、Avi、Dv、Mp3、Wave等，为多媒体流的捕捉和回放提供了强有力的支持。(DirectShow is Microsoft Corp's ActiveMovie and Video for Windows based on the launch of a new generation of COM (Component Object Model) streaming media development package, and DirectX development kits released together. The process, DirectShow uses a Filter Graph model to manage the entire data stream using DirectShow, we can easily drive the model from the support WDM card to capture data, and the corresponding post processing and storage to a file. As a result, access to multimedia data becomes more convenient in a multimedia database management system (MDBMS). It supports a wide variety of media formats, including Asf, Mpeg, Avi, Dv, Mp3, Wave and so on. It provides strong support for the capture and playback of multimedia streams.) Platform: |
