Combined Community Codec Pack

The Combined Community Codec Pack, more commonly referred to as the CCCP, is a filter pack for Microsoft Windows designed originally for the playback of anime fansubs. The CCCP is developed and maintained by members of various fansubbing groups. The name is a pun on the Союз Советских Социалистических Республик (Soyuz Sovyetskikh Sotsialistichyeskikh Respublik), the Russian name for the USSR; the Cyrillic name for the USSR is initialized CCCP, however it transliterates to SSSR.

As of 2006, the CCCP is now the official Matroska playback solution on Windows, having superseded the Matroska Playback Pack.
