DirectShow技术在视频转码中的应用研究

The Application Research of DirectShow in Video Transcoding

随着计算机技术和多媒体技术的发展,数字视频技术在现实生活中获得了广泛的应用。在实际应用中,经常需要把视频从一种格式转变为另一种格式,文中就运用DirectShow来进行视频转码作了介绍,并且以AVI文件转换为ASF文件为例,说明了如何利用DirectShow技术来构建格式转换方案,以及如何编程实现这个方案。

With the development of technology of computer and multi-midea, digital videos have been used widely. In practical use, videos are usually transformed from one type into another. Taking the transformation of AVI documents into ASF as an example, the essay explores how to conduct video transcoding with DirectShow, as well as how to construct transcoding methods and how to realize it.
