INTRODUCTION

In the last few years the Open Source movement has changed the face of computing more than almost anyone would have thought possible. Many people in the industry believe that these changes are the most important changes in computing since IBM contracted Microsoft to write an for their personal . This article is intended to discuss the history, philosophy, and legal issues relating to Open Source. What is Open Source?

Open Source or open-source software is different from . In Open Source, the source code used in the software is available to anyone to examine, evaluate, and adapt. Open source has had an important impact on the way many developers view and create software. End users often use the term open-source to cover a variety of free and open source software.

The has this for a definition of open-source software:

Open source doesn't just mean access to the source code. The distribution terms of open-source software must comply with the following criteria:

1. Free Redistribution The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.

2. Source Code The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge. The source code must be the preferred form in which a would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.

3. Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.

4. Integrity of The Author's Source Code The license may restrict source-code from being distributed in modified form only if the license allows the distribution of "patch files" with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.

5. No Discrimination Against Persons or Groups The license must not discriminate against any person or group of persons.

6. No Discrimination Against Fields of Endeavor The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

7. Distribution of License The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.

8. License Must Not Be Specific to a Product The rights attached to the program must not depend on the program's being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program's license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.

9. License Must Not Restrict Other Software The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.

10. License Must Be Technology-Neutral No provision of the license may be predicated on any individual technology or style of interface.

Figure 1: The Open Source Model: Source code is available to public. The public is free to make improvements.

What is Free Software?

Free software is software that adheres to the concept of the four freedoms of software, as articulated by the GNU Project. These four freedoms are as follows:

 The user is free to use the software for any purpose.

 The user is free to study the mechanisms by which the program operates and to adjust these mechanisms to a specific purpose.

 The user is free to redistribute the software to another user.

 The user is free to adapt and improve the program and release these adaptations and improvements to the public. Free Software shares much of its philosophy with Open-Source software, but many people within the open source community feel that there are important distinctions between the terms, as described in the section Free Software vs. Open-source software.

Often Free Software is referred to as "free as in speech, not as in beer", stressing the idea that the Free-software movement is concerned with freedom, not with price. Throughout this book the reader should assume that the word "free" is referring to freedom.

Free Software vs. Open Source software

The primary distinction of open source software is that it's not about freedom, it's about what software does things better.

As a whole the movement is often called "Free and Open-Source software" (FOSS). For the purposes of clarity the abbreviation FOSS will be used when describing issues that apply to all open source software projects, whereas OSS will be used when describing issues that apply only to software with open-source licenses that allow future developers to close the source code, and FSS will be used when talking about issues that apply only to software with free licenses requiring future developers maintain the previous style of licensing (if not the license itself).

FOSS does not mean no cost

This is a common misunderstanding about FOSS, in no small part because nearly all FOSS programs are available free of charge. For example when the text editor Emacs was first released charged from time to time to get copies. Developers have the choice to charge under most FOSS licenses, although they rarely choose to. The only requirement to be a truly FOSS project is that the publisher provides the source code with the program, and to allow the user to edit that code.

On top of the initial cost of purchasing software, there are other ongoing costs associated with all software. This can come in the form of support agreements, the cost of customization, training costs support personnel and other sources. This is true of both traditional commercial software and FOSS programs. There is a large and active debate about which type of software is more expensive over the long run for large corporations, for individual users there is little to no question that FOSS is cheaper.

What is source code?

The source code of any software is written in a programming language, for example , Pascal or web programming languages like PHP. This code is written in textual form. The source code consists of instructions that define how a program behaves. The programmer can add or change instructions to adjust the program’s behaviour and add functionality. (Weber, 2004, p.4) Figure shows an example of a very basic piece of source code and its result.

This code is written in the web language PHP. By pointing a browser to the file on the , the result as shown on the left is displayed. The lines in the code preceded by two slashes (//) are comments. These are ignored when the code is executed, and are used to explain what certain code does and why. The words preceded by a dollar sign ($) are variables in which values of executed code can be stored.

Misunderstandings (?) of ``OpenSource”:-

The Open Source Definition is clear enough, and it is quite clear that the typical non-free program does not qualify. So you would think that ``Open Source company'' would mean one whose products are free software (or close to it), right? Alas, many companies are trying to give it a different meaning.

At the ``Open Source Developers Day'' meeting in August 1998, several of the commercial developers invited said they intend to make only a part of their work free software (or ``open source''). The focus of their business is on developing proprietary add-ons (software or manuals) to sell to the users of this free software. They ask us to regard this as legitimate, as part of our community, because some of the money is donated to free .

In effect, these companies seek to gain the favorable cachet of ``open source'' for their proprietary software products--even though those are not ``open source software''--because they have some relationship to free software or because the same company also maintains some free software. (One company founder said quite explicitly that they would put, into the free package they support, as little of their work as the community would stand for.)

Some Open Source Softwares

Open-source software is software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees.[19] Open source code can evolve through community cooperation. These communities are composed of individual as well as very large companies. Examples of open-source software products are:[20]

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

VLC is a portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as , 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 since VLC is no longer simply a client, that initialism no longer applies.[2][3]

It is a cross-platform media player, with versions for , MacOSX, GNU, Linux, BeOS, MorphOS, BSD, Solaris, Android, iOS, andeComStation.[4]

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 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 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 , 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.[5] 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.[6] The cone icon design was changed from a hand drawn low resolution icon[7] to a higher resolution CGI-rendered version in 2006, illustrated by Richard Øiestad.[8]

After 13 years of development, version 1.0.0 of VLC media player was released on July 7, 2009.[9]

VLC is 3rd in the sourceforge.net overall download count.[10] 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.[11]

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 and all file formats supported by libavcodec and libavformat. This means that VLC can play back H.264 or MPEG- 4video 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, mirror videos, 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 -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.[14] VLC can play videos in the AVCHD format, a highly compressed format used in recent HD camcorders. VLC can generate a number of displays.

Another way of doing it

INSTALATION OF VLC ON VARIOUS OS

VLC media player is compatible and works under Windows Operating Systems 2000/XP/Vista/7. It can also be used under Windows 95/98/Me usingKernelEx.

1. Download the self-extracting package (or the 7-zip/zip package, which requires an extraction first) from the VLC Windows download page. 2. Launch the .exe to install VLC. 3. Follow the steps in the installer.

1. Download the Mac OS X package from the VLC MacOS X download page. 2. Double-click on the icon of the package: an icon will appear on your Desktop, right beside your drives. 3. Open it and drag the VLC application from the resulting window to the place where you want to install it (it should be /Applications).

1. Download the Zip file from the VLC BeOS download page. 2. Unzip the file in a directory to install VLC.

Linux Mandrake

There are VLC packages for Mandrake 9.1 and Cooker. To install them, add the following sources for either Mandrake 9.1 or Cooker (you can use Easy urpmi for that): contrib from the core distribution and plf (Penguin Liberation Front) from the external add-ons. Then install the required packages with urpmi:

# urpmi libdvdcss2 libdvdplay0 wxvlc vlc-plugin-a52 vlc- plugin-ogg vlc-plugin-mad

Debian stable (lenny) Add the following lines to your /etc/apt/sources.list: deb http://download.videolan.org/pub/videolan/debian stable main deb-src http://download.videolan.org/pub/videolan/debian stable main

Then, for a normal install, write the following commands in Terminal:

# apt-get update # apt-get install vlc libdvdcss2

Debian testing (squeeze) You should not be using Debian testing unless you perfectly know what you are doing. It is almost impossible to support Debian testing and there are no plans to do it. For more information on Debian testing, please look at the Testing Page. Debian unstable (sid) Add the following lines to your /etc/apt/sources.list: deb http://download.videolan.org/pub/videolan/debian sid main deb-src http://download.videolan.org/pub/videolan/debian sid main

Then, for a normal install, write the following commands in Terminal:

# apt-get update # apt-get install vlc libdvdcss2

Linux (EL5)

1. Download and install the latest rpmforge-release rpm (eg rpmforge-release-0.3.6- 1.el5.rf.i386.rpm) 2. Either;

# yum install vlc or (if you have epel-release installed);

# yum --disablerepo='epel' install vlc

Linux Download the RPM package vlc and the packages listed in the required libraries and codecs section (the other packages are optional) from the VLC Red Hat download page and put them all into the same directory. Then install the RPM packages you have downloaded:

# rpm -U *.rpm

If you have not installed all the RPM packages included with your distribution, you may be asked to install a few of them first.

PLAYING AUDIO IN VLC

Playing an Audio Track You can play, enable and disable an audio track. To play a track: 1. Select Open File from the Media menu.

2. Select an audio file and click on the Open button. The selected track is played. 3. To disable a track, select the Disable option in the Audio Track from the Audio menu. The selected track will then stop. 4. To play the same track again, select the designated Track option in the Audio Track from the Audio menu. The selected track will then play. Recording Audio

You can record an audio track by pushing the record button ( ). In the default interface, you will not see the record button, but you can choose View->Advanced Controls or customize the interface (View->Customize) and add the record button to Line 2 (which is shown by default). The recording from a stream is stored somewhere in your files under a name like vlc-record-Date-Time-Channel- Track.mp3 (e.g.: "vlc-record-2011-09-22-10h19m48s-Radio CAFF- Silencio - Arrabal Salvaje.mp3", when recording from Radio CAFF (or more precisely from the underlying stream). Under my german Windows XP it was stored under "Eigene Dateien/Eigene Music" so I guess that you find it in an english Windows under "My Documents/My Music/", I don't know where it will be stored under Linux or any other OS (updates are welcome). You can automagically cut the stream into tracks by relaying the stream through Streamripper, i.e. by directing StreamRipper to the ShoutCast stream and directing VLC to the relaying port of StreamRipper (default http://localhost:8000). Audio Device

This option helps you to listen to audio files in two modes: stereo and .

1. To listen to an audio track in either the Stereo or Mono mode, select Open File or Open Disc from the Media menu. The Open dialog box is displayed.

2. Select an audio file and click on the Play button. The selected track is played. 3. Select Mono in Audio Device from the Audio menu if you want to listen to the audio track in the Mono mode. Mono refers to monaural sound that uses a single channel for sound reproduction.

1. Select Stereo in Audio Device from the Audio menu if you want to listen to the audio track in the Stereo mode. Stereo refers to sound that uses two channels for sound reproduction or stereophonic sound.

PLAYING VEDIOS IN VLC

Playing a Video Track

There are two main ways to open and play a video track:

1. Select Open File from the Media menu. 2. Select a video track and double-click it or click the Open button. The selected track will be played. Loading Subtitle Tracks

A subtitle is a textual version of a movie’s dialogue. are helpful if you are viewing a movie in a language that is not understandable to you. You can load subtitles for video tracks. Subtitles of the formats .cdg, .idx, .srt, .sub, .utf, .ass, .ssa, .aqt, .jss, .psb, .rt and smi are supported. VLC can read subtitles for the media formats such as DVD, SVCD, OGM files, and Matroska (MKV) files. To enable the subtitle for a track:

1. Select Open File under the Subtitle menu item from the Video menu. The Open Subtitles File dialog box is displayed. 2. Locate the file which contains the subtitle and click on Open. The subtitles are displayed. For more details, see Subtitles. Full Screen

This option is useful if you want to watch the video in the full screen mode.

1. Select Full Screen from the Video menu. The video will then occupy the entire screen. 2. To return to the original mode, press Esc on the keyboard or right-click the mouse and select the Leave Full Screen option. The video will then return to its original mode. Note: When you switch to full screen, the controls may appear for a short period of time. To restore the controls after they disappear, move the mouse or press any key

on the keyboard.

Always on Top This option is useful if you want the VLC media player to remain on the top of the screen always when other applications or files are open.

1. To make the VLC media player appear on top of the screen, select Always on Top from the Video menu. 2. If you do not want VLC to appear on the top of the screen, select the Always on Top option from the Video menu and manually minimise the VLC application. DirectX Wallpaper

This option is useful if you want to display the video which is being played as your desktop wallpaper. To view the current video file as wallpaper

1. Select Advanced File Open from the Media menu. The Open Media dialog box is displayed.

2. Select a file and click Play. 3. Select DirectX Wallpaper from the Video menu. The wallpaper mode will then display the video as the desktop background. Note: that this feature works only if you deactivate the overlay under Windows XP. Snapshot

This option is useful if you want to capture a portion of the video as an image.

1. Select Advanced File Open from the Media menu. The Open dialog box is displayed.

2. Select a file and click Play. 3. To capture an image from the video, select Snapshot from the Video menu. The image is captured in the .png picture format and is saved in the C:\My Pictures folder by default (C:\Users\Username\Pictures). Zoom

You can enlarge videos in different sizes. This option is useful if you want to change the size of a video track which is being played. The supported sizes are 1:4 Quarter, 1:2 Half, 1:1 Original (default) and2:1 Double. To view a video in a particular dimension, select a dimension from Zoom in the Video menu. The track is then resized based on the selected zoom ratio. Aspect Ratio Aspect ratio refers to the width of a picture in relation to its height. For example, the ratio 4:3 means four units wide to three units high. VLC provides a list of aspect ratio values which are Default, 1:1, 4:3, 16:9, 16:10, 2.21:1, 2.35:1, 2.39:1 and 5:4. To select an aspect ratio, select a value from Aspect Ratio in the Video menu. The video is then adjusted based on the selected ratio. Crop

This option is helpful if you want to capture a small portion of a video as an image. This also helps crop the black bars of the top and bottom of a video. The cropping values that are supported are Default, 16:10, 16:9, 1.85:1, 2.21:1, 2.35:1, 2.39:1, 5:3, 4:3, 5:4, and 1:1. To crop a video that is played, select a value from Crop in the Video menu. The video is then cropped based on the selected value. Deinterlace Deinterlace refers to a where interlaced video signals are converted into non-interlaced signals. VLC provides the Discard, Blend, Mean, Bob, Linear, X, Yadif and Yadif (2x) deinterlacement modes.

1. Select Deinterlace from the Video menu and choose the appropriate setting. 2. To change the deinterlacement mode select 'Deinterlace mode' is the Video Menu 3. Select a mode and observe the change in the video being played.

PLAYBACK ON VLC

VLC media player helps you to create media files. After creating media files, the quality has to be tested. You can test the quality and several other parameters using playback. In playback, you can specify parameters such as time, bookmarks, and titles.

Bookmarks You can mark and locate particular places in an audio or video file using the Bookmarks feature of VLC. If you want to view a particular scene in a movie or listen to certain tune in a song repeatedly, you can create bookmarks. To bookmark a scene in a movie:

1. From the Playback menu select the Bookmarks option, and the Manage Bookmarks. The Edit Bookmarks dialog box will be displayed. 2. Click Create to create a bookmark for the current track. The created bookmark is displayed in the Edit Bookmarks dialog box. 3. To view a scene that is bookmarked, select a bookmark from Bookmarks in the Playback menu. Note: Loading bookmarks is currently broken as of 0.9.9 see http://trac.videolan.org/vlc/ticket/2100. However it is confirmed that the current latest versionVLC 1.1.5 is able to load bookmarks.

Edit Bookmarks dialog box under Windows in VLC 1.1.5 Title

In a DVD format, each movie is referred to by its title or name. A title is displayed whenever a movie is played by any media player. You can view all titles in a folder in a sequential manner.

1. To open a folder, select Open Folder from the Media menu. Locate the folder in which the video files are present and click OK. 2. To select a title, click Title in the Playback menu. The selected title is then played. Chapter A video is divided into chapters. Different chapters can be accessed at random in a video which is being played. Using this option, you can directly view your favourite chapter without having to see the complete video. To play a chapter:

1. Select Open Folder from the Media menu. 2. Locate the folder in which the video files are present. 3. Select a video file and click OK. The file is played in the VLC media player.

1. Select Chapter in the Playback menu to view the list of chapters. Select a chapter of your choice. Then selected chapter is played. Navigation

In VLC, you can navigate to different titles and their corresponding chapters. You can also customise a DVD by selecting options such as subtitle, angle and so on. 1. To customize a title, select the required option from DVD Menu in the Navigation menu. 2. To view a title, select a Title under Navigation in the Playback menu. The selected title is played. 3. To view a chapter in a title, select Title. When you select a title, the chapters in a title are listed. Select a chapter. Refer to Title and Chapter sections for more details. Program

This option is enabled only if streams of format DVB and TS are played. Choose the program to select by giving its Service ID. Only use this option if you want to read a multi-program stream (like DVB streams for example). Description needs to be improved Specify the time

This option is used to go to a specific frame in a media file and listen or view once again.

1. To specify time select Jump to Specific Time from the Playback menu. The Go to Time dialog box is displayed. 2. Enter the time in hh:mm:ss. 3. Click on the Go button. The control moves the to a specific frame and the media file continues from that specified frame. 4. Click Cancel to exit the dialog box. Note: Ensure that time limit is within the range of length of the media file.

TROUBLESHOUTING IN VLC

File does not play, only sound or only video

Maybe the file you are trying to read is not fully supported by VLC media player. VLC does not use the codec packs (the software that decodes video signals) you might have installed. It comes with its own codecs. If there is no open-source decoder for the format you are trying to read, it won't be supported (There is an exception, under Windows, for codecs that use the DirectShow framework). To find out, open the Messages window in the Tools tab and restart your stream. Look for error messages (red messages).

In this example, the file contains a IV41 video stream, a codec that is not supported by VLC. You may of course have other messages. If you post them to a VideoLAN mailing list or in the forum, please include such a log. It is very valuable in troubleshooting. Weird VLC behavior and crashes A very common thing is a corrupted VLC preferences file. Don't hesitate to delete it if problems appear suddenly. You will find in the FAQ details on how to delete your preferences file. Computer crashes / Video is corrupted

Another common problem is buggy video drivers. Try upgrading them from the website of your video card's manufacturer. Also, you can try disabling Overlay (Preferences/General/Video, untick "Overlay video output").

UNINSTALLING VLC

Frequently Asked Questions On VLC

What is VideoLAN? What is the VideoLAN Team? VideoLAN is a group of people, that produces and distributes free and open source software for video and multimedia purpose, released under Open Source licenses. It started as a student project at the French École Centrale Paris but is now a worldwide project with developers from everywhere and dozens of millions of people using VideoLAN's software. What is the legal structure of VideoLAN? VideoLAN is a French non-profit organization. VideoLAN has its own bank account and is fully responsible of this website. What are the differences between VLC, VLC media player, VideoLAN Client, VideoLAN Server and VideoLAN? VLC is the official name of VideoLAN's main product, often named VLC. VideoLAN Client is an ancient name of this product. VideoLAN Server is another product of VideoLAN, but is discontinued since a long time. Does VLC support DVDs from all regions? This mostly depends on your DVD drive. Testing it is usually the quickest way to find out. The problem is that a lot of newer drives are RPC2 drives these days. Some of these drives don't allow raw access to the drive untill the drive firmware has done a regioncheck. VLC uses libdvdcss and it needs raw access to the DVD drive to crack the encryption key. So with those drives it is impossible to circumvent the region protection. (This goes for all software. You will need to flash your drives firmware, but sometimes there is no alternate firmware available for your drive). On other RPC2 drives that do allow raw access, it might take VLC a long time to crack the key. So just pop the disc in your drive and try it out, while you get a coffee. RPC1 drives should 'always' work regardless of the regioncode. Where does VLC store its config file? Currently, a config file is created on a per user basis (there is no global configuration file). If you modify the available options in VLC and save the new configuration, then a configuration file will be created in your user directory. The precise location of this file depends on the Operating System you are running:  Linux / Unix: $(HOME)/.config/vlc/vlcrc (v0.9.0 and above), $(HOME)/.vlc/vlcrc (v0.8 and older)  Mac OS X: HOME/Library/Preferences/org.videolan.vlc HOME/Library/Prefer ences/VLC (v0.9 and older)  Windows 95/98/ME: C:\Windows\Application Data\vlc\vlcrc  Windows 2000/XP: C:\Documents and Settings\%username%\Application Data\vlc\vlcrc  Windows Vista/7: C:\Users\%username%\Application Data\vlc\vlcrc  BeOS: config/settings/vlcrc VLC crashes. Increase the verbosity (either in the preferences or with a - vv command line option) and look at the debug messages (in the terminal or in the Messages window). If you are convinced that it is a bug in VLC, have a look at the bug reporting page. How can I take screenshots? To take a snapshot of the video displayed by VLC, you just need to press the pre-defined snapshot hotkey:  Windows / Linux / Unix: Ctrl+Alt+S  Mac OS X: Command+Alt+s To change it, go to Preferences -> Interface -> Hotkeys settings, check Advanced options, and set Take video snapshot. You can also take a snaphot via the menu Video -> Snapshot. To change the snapshot format or directory, go to Preferences -> Video. Where are my screenshots? If you haven't changed the snapshot directory in your preferences, your screenshots should go to:  Windows: My Documents\My Pictures\  Linux / Unix: $(HOME)/.vlc/  Mac OS X: Desktop/ To change it, go to Preferences -> Video -> Video snapshot directory.
