VLC media player (also known as VLC) is a highly portable free and open-source media player and streaming media server written by the VideoLAN project. It is a cross-platform media player, with versions for Microsoft Windows, Mac OS X, Linux, BeOS, MorphOS, BSD, Solaris, iOS, and eComStation.[12]
VLC media player supports many audio and video compression methods and file formats, including DVD-video, video CD and streaming protocols. It is able to stream over computer network and to transcode multimedia files.[12]
VLC used to stand for VideoLAN Client, but since VLC is no longer simply a client, that initialism no longer applies.[13][14]
The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding 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 and its own protocols. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and Mac OS X by using the libdvdcss DVD decryption library.
History
The VideoLan project was originally started as an academic project in 1996. It was intended to consist of a client and server to stream videos across a campus network. VLC was the client for the VideoLAN project, with VLC standing for VideoLan Client. Originally developed by students at the École Centrale Paris, it is now developed by contributors worldwide and is coordinated by the VideoLAN non-profit organization.
Rewritten from scratch in 1998, it was released under the GPL on 1 February 2001. The functionality of the server program, VideoLan Server (VLS), has mostly been subsumed into VLC and has been deprecated.[15] The project name has been changed to VLC because there is no longer a client/server infrastructure.
The cone icon used in VLC is a reference to the traffic cones collected by Ecole Centrale's Networking Students' Association.[16] The cone icon design was changed from a hand drawn low resolution icon[17] to a higher resolution CGI-rendered version in 2006, illustrated by Richard Øiestad.[18]
After 13 years of development, version 1.0.0 of VLC media player was released on July 7, 2009.[19]
The version 2.0.0 of VLC media player was released on February 18, 2012 [11][20]
VLC is second in the sourceforge.net overall download count.[21] VLC was available for the iPad, iPhone, and iPod Touch from the Apple AppStore, but was pulled due to a licensing conflict between the GPL and the iTunes Store agreement.[22]
Design principles
Interfaces
In VLC, interfaces are modules, which means that VLC's core can launch one, many, or no interfaces.
The default GUI is based on Qt 4 for Windows and Linux, Cocoa for Mac OS X, and Be API on BeOS; but all give a similar standard interface. The old default GUI was based on wx on Windows and Linux.[23]
The interface contains an easter egg which changes the VLC traffic cone logo so that it's wearing a Santa hat. The logo changes on December 18, one week before Christmas, and reverts to its normal appearance on January 1.
VLC supports highly customizable skins through the skins2 interface, also supporting Winamp 2 and XMMS skins. The customizable skins feature can malfunction depending on which version is being used.
For console users, VLC has a remote control interface and an ncurses interface. As VLC can act as a streaming server, rather than a media player, it can be useful to control it from a remote location and there are interfaces allowing this. The Remote Control Interface is a text-based interface for doing this. There are also interfaces using telnet and HTTP (Ajax).
Control
In addition to these interfaces, it is possible to control VLC in different ways:
- Configurable hotkeys
- Mouse gestures
- LIRC and infrared controllers
- D-Bus
- Laptop motion
- Remote control software for mobile operating systems such as Android, Symbian and iOS (iPad, iPhone, iPod Touch)
Modular design
VLC, like most multimedia frameworks, has a very modular design which makes it easier to include modules/plugins for new file formats, codecs, or streaming methods. VLC 1.0.0 has more than 380 modules.[24]
The VLC core creates dynamically its own graph of modules depending on the situation: input protocol, input file format, input codec, video card capabilities and other parameters. In VLC, almost everything is a module, like interfaces, video and audio outputs, controls, scalers, codecs, and audio/video filters.
Features

Because VLC is a packet-based media player, it can play the video content of some damaged, incomplete, or unfinished videos (for example, files still downloading via peer-to-peer (P2P) networks). It also plays m2t MPEG transport streams (.TS) files while they are still being digitized from an HDV camera via a FireWire cable, making it possible to monitor the video as it is being played. The player can also use libcdio to access .iso files so that users can play files on a disk image, even if the user's operating system cannot work directly with .iso images.
VLC supports all audio and video formats supported by libavcodec and libavformat. This means that VLC can play back H.264 or MPEG-4 video as well as support FLV or MXF file formats "out of the box" using FFmpeg's libraries. Alternatively, VLC has modules for codecs that are not based on FFmpeg's libraries. VLC is one of the free software and open source DVD players that ignores DVD region coding on RPC-1 firmware drives, making it a region-free player. However, it does not do the same on RPC-2 firmware drives. VLC media player has some filters that can distort, rotate, split, deinterlace, and mirror videos as well as create display walls or add a logo overlay. It can also output video as ASCII art.
VLC media player can play high definition recordings of D-VHS tapes duplicated to a computer using CapDVHS.exe. This offers another way to archive all D-VHS tapes with the DRM copy freely tag. Using a FireWire connection from cable boxes to computers, VLC can stream live, unencrypted content to a monitor or HDTV. VLC media player can display the playing video as the desktop wallpaper, like Windows DreamScene, by using DirectX, only available on Windows operating systems. VLC media player can create screencasts and record the desktop. On Microsoft Windows, VLC also supports the Direct Media Object (DMO) framework and can thus make use of some third-party DLLs. On most platforms, VLC can tune in to and view DVB-C, DVB-T, and DVB-S channels. On Mac OS X the separate EyeTV plugin is required, on Windows it requires the card's BDA Drivers.
VLC can be installed or run directly from a USB flash drive or other external drive. VLC can be extended through scripting. It uses the Lua scripting language.[25] VLC can play videos in the AVCHD format, a highly compressed format used in recent HD camcorders. VLC can generate a number of music visualization displays. The program is able to convert media files into various supported formats.[26]

Browser plugins
On Windows, Linux, Mac, and some other Unix-like platforms, VLC provides an NPAPI plugin,[33] which enables users to view QuickTime, Windows Media, MP3, and Ogg files embedded in websites without using additional products. It supports many web browsers including Firefox, Mozilla Application Suite, and other Netscape plug-in based browsers; Safari, Chrome, and other WebKit based browsers; and Opera. Google used this plugin to build the Google Video web browser plugin before switching to use Adobe Flash.[34]
Starting with version 0.8.2, VLC also provides an ActiveX plugin, which lets people view QuickTime (MOV), Windows Media, MP3, and Ogg files embedded in websites when using Internet Explorer.
Applications that use the VLC plugin
VLC can handle some incomplete files and in some cases can be used to preview files being downloaded. Several programs make use of this, including eMule and KCeasy. The free/open-source Internet television application Miro also uses VLC code. HandBrake, an open-source video encoder, loads libdvdcss from VLC Media Player.

Android support
As of May 2012, the VLC team states that a version of VLC for Android "is in development".[46] On 29 December 2011, Softpedia reported "Also important is the fact that almost every video filter can now be transcoded and it can be ported to mobile operating systems (Android and iOS) as well as 64-bit Windows."[47]
Despite no official version being yet available, a non-official Android build has been compiled by Austen Dicken, based on the "pre-alpha" source code of VLC for Android, by the VLC team.[48][49][50][51]
Legality
The VLC media player software installers for the Mac OS X platform and the Windows platform include the libdvdcss DVD decryption library, even though this library may be legally restricted in certain jurisdictions.[52][53]
USA
At least one recent release of the VLC media player software is able to read video and audio data from DVDs that incorporate Content Scramble System (CSS) encryption, even though the VLC media player software lacks a CSS decryption license.[54] The unauthorized decryption of CSS-encrypted DVD content and/or the unauthorized distribution of CSS decryption tools may violate the US Digital Millennium Copyright Act,[54] although the decryption of CSS-encrypted DVD content has been temporarily authorized for certain purposes (such as documentary filmmaking that uses short portions of DVD content for criticism and/or commentary) under the Digital Millennium Copyright Act anticircumvention exemptions that were issued by the US Copyright Office in 2010.[55] (These exemptions do not change the DMCA's ban on the distribution of CSS decryption tools.)[56]
