mplayer (media player for *nix)

Media player for linux (runs on many other Unices and non-x86 CPUs; see the documentation) plays most MPEG, VOB, AVI, OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, YUV4MPEG, FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL codecs.
