Media playerA Media player is a piece of software tailored for playing back different forms of multimedia file formats.
Formats that are generally played back by a competent Media player include DVD, CDDA, MPEG video, DivX, MP3, Karaoke (*.Kar), Ogg-variants and FLAC. Generally speaking, the more formats it can play, the better it is. Hard-to-get-at formats like QuickTime using the Sorenson codec are less common in media players.
There also exist hardware media players, such as MP3 players.
