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.
