CCCP (Combined Community Codec Pack)是一个普遍用于动漫影片的解码器安装包，安装后Media Classic Player或Windows Media Player就可以播放MKV格式的文件。当然计算机的其它各种音视频格式他也支持的。提供了对多核处理器的支持，上个版本还是2月份的，终于更新了，新版本去掉了Win9x支持以及更多的更新。虽然这里的CCCP不是Союз Советских Социалистических Республик，但是看得出来弄这个的家伙还是很怀念苏联的嘛。

The CCCP (Combined Community Codec Pack) is a DirectShow filter pack specifically built for playing anime. It has been assembled by some of the most knowledgeable people in online anime distribution, and one of the primary design goals is to play as much as possible with as little as possible. The CCCP attempts to be as unintrusive on your system as possible. The pack is also now officially endorsed by the Matroska Project, the developers who designed the MKV format.
