MpegNetwork
- MPEG4是一种压缩率高、对传输带宽要求低、图像质量高的图象编码技术。提出了一套视频传输系统的实现方案。该方案基于OMAP1510具有的独特双核结构,结合蓝牙和MPEG4编码技术,实现窄带宽下的视频图像实时传输。-MPEG4 is a high compression ratio, and low transmission bandwidth, high image quality image coding techniques. A set of video transmission syst
7-Zip_v465_src
- 7-Zip 是一款号称有着现今最高压缩比的压缩软件，不用多说，只要从这个源码包就可以看出(解压缩后有37.6 M)。本人将它的控制台版本和自解压模块进行了翻译，以方便广大人民群众使用！同时更换了些图标使用惯了 WinRAR 的用户更习惯。推荐使用 vs2005 或 vs2008 编译。-7-Zip is a known today has the highest compression ratio of compression software, Needless to say, as long
LZZQ
- Compression speed ~= Decompression speed. (around 200-300 MB/s) CPU notes: LZZQ uses 32KB dictionary, reduce to 16KB (change HASH_SIZE to 4*1024) for good L1 cache access (with little reduction in ratio).
