VLC media player is a free and open source media player and multimedia framework written by the VideoLAN project.

VLC is a portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as DVDs, VCDs, and various streaming protocols. It is able to stream over networks and to transcode multimedia files and save them into various formats. VLC used to stand for VideoLAN Client, but that initialism is now deprecated.

It is one of the most platform-independent media players available, with versions for Microsoft Windows, Mac OS X, Linux, BeOS, and BSD.

The default distribution of VLC includes a large number of free decoding and encoding libraries; on the Windows platform, this greatly reduces the need for finding/calibrating proprietary plugins. Many of VLC’s codecs are provided by the libavcodec library from the FFmpeg project, but it uses mainly its own muxer and demuxers. It also gained distinction as the first player to support playback of encrypted DVDs on Linux by using the libdvdcss DVD decryption library.
