zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.

VFW(Video for Windows)是Microsoft推出的关于数字视频的一个 VFW logo 软件开发包，VFW的核心是AVI文件标准。AVI(Audio Video Interleave)文件中的音、视频数据帧交错存放。围绕AVI文件，VFW推出了一整套完整的视频采集、压缩、解压缩、回放和编辑的应用程序接口(API)。它引进AVI的文件标准，该标准未规定如何对视频进行捕获、压缩及播放，仅规定视频和音频该如何存储在硬盘上，在AVI文件中交替存储视频帧和与之相匹配的音频数据
