“The Media Player Codec Pack supports almost every compression and file type used by modern video and audio files. The package is simple to install, while also offering advanced settings to the high end user. A codec is a piece of software on either a device or computer capable of encoding and/or decoding video and/or audio data from files, streams and broadcasts. The word Codec is a portmanteau of 'compressor-decompressor'”
From Cole Williams, this software contains multiple media codecs. Note, the Windows 7 Codec Pack installed various adware including the SearchMe toolbar by Spigot during installation.
