About VLC media player

VLC media player is a highly portable multimedia player for various audio and video formats such as MPEG-1, MPEG-2, MPEG-4, DivX, mp3 and ogg. It also plays DVDs, VCDs, and various streaming networks. In addition to playing audio and video files, VLC media player provides additional formats which can be played and customized.

VLC media player was initially known as VideoLAN Client. However, in recent years, the software has also become an extremely powerful server to stream live and on-demand video in several formats to the intranet network and the Internet.

It started as a student project at the French École Centrale, Paris, but is now a worldwide project with developers from more than 20 countries.

VLC is built in a modular way. This means that you can choose from a range of different modules to decide how to control VLC and how to display the video output.

Note: The screenshots are taken from the MS Windows XP version. On other operating systems they might appear slightly different.

Understanding the VLC interface

VLC has several interfaces:

• A cross-platform interface, for Windows and GNU/Linux, called wxWidgets,
• A native Mac OS X interface, and
• A skinnable interface for Windows and GNU/Linux.

Screenshots below are drawn from the various interfaces, but VLC's functions work essentially the same on all operating systems.

Windows and GNU/Linux (Qt)

The main interface of VLC media player looks as shown in the following figure. This is the default interface on Windows and GNU/Linux (the screenshot is done on Windows, but it would look quite the same on GNU/Linux).

Starting VLC Media Player

To start VLC Media Player

1. Select Programs from the Start menu.
2. Select VideoLAN and select the VLC media player.

When you start VLC media player, the application appears on the screen and a small icon File:VLCIcon.jpg appears in the taskbar. Click on the icon in the taskbar to show or hide the icon in the taskbar. Hiding the icon does not amount to quitting the application. It does run in the background even when you hide the interface.

Stopping VLC Media Player

To quit the application, right click on the File:VLCIcon.jpg icon in the tray and select Quit.
Or
Click the Close button in the main interface of the application.

Taskbar Icon

When VLC media player is running, its icon File:VLCIcon.jpg appears in the taskbar. Click on the icon in the taskbar to show or hide the icon in the taskbar. Hiding the icon does not amount to quitting the application. It does run in the background even when you hide the icon. Basic operations such as opening, playing or stopping a media file, or changing a track can be done from the menu obtained by right clicking the taskbar icon. The main interface contains a couple of sections:

Main Interface

Menu bar
The menu bar at the top contains all the options.
Track slider
The track slider is below the menu bar. It shows the progress of playing the media file. You can drag the track slider left to rewind or right to forward the track being played. When a video file is played, the video appears between the menu bar and track slider.
Note: When a media file is streamed, the track slider does not move because VLC cannot know the total duration.

Control Buttons
The buttons below the slider help in controlling the play.

Streaming Media Files

Streaming is a method of delivering audio or video content across the network without downloading a file before it is played. You can view or listen to the content as it arrives. The advantage is that you need not download large files to watch a movie or listen to music. VideoLAN is designed to stream MPEG videos on high bandwidth networks.

VLC can be used as a server to stream MPEG-1, MPEG-2 and MPEG-4 files, DVDs and live videos on the network in unicast or multicast.

Unicast refers to a process where media files are sent to a single system through the network. Multicast refers to a process where media files are sent to multiple systems through the network.

VLC is also used as a client to receive, decode and display MPEG streams. MPEG-1, MPEG-2 and MPEG-4 streams received from the network or video from a camcorder can be sent to one machine or a group of machines.



To stream a file

1. Select Streaming from the Media menu. The Open dialog box is displayed. The Open File tab is selected by default.
2. Select the media file from the options available such as a file, a network, a disc or a capture device.
3. Click on Stream. The Stream Output dialog box is displayed. Refer to Specifying Streaming Options.
4. Click on Stream in the Stream Output dialog box.

Note: When the streaming is being done, the slider moves to show the progress.

Converting and Saving a Media File Format

VLC media player is the best option for multimedia conversion. It can convert different media formats to the format of your preference. To convert a media file

1. Select Open File from the Media menu. The Open dialog box is displayed.
2. Select a media file and click on the Open button. The media file is played.
3. Select Convert/Save from the Media menu. The Open dialog box is displayed.
4. Select the media file and click on Convert. The Stream Output dialog box is displayed. Refer to Specifying Streaming Options

Audio

Using the VLC media player, you can play audio files of different formats. You can enable tracks, convert audio tracks, view tracks in various visualizations, and set visualizations. Audio tracks of the .asf, .avi, .divx, .dv, .mxf, .ogg, .gm, .ps, .ts, .vob, and .wmv formats are supported.

Note: The options under the Audio menu are enabled only if an audio file is played.

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 Play 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 stops.
4. To play the same track again, select the Track 1 option in the Audio Track from the Audio menu. The selected track is played.

Audio Device

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

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 monoaural sound that uses a single channel for sound reproduction.
4. 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.

Audio Channels

In audio, a channel refers to a stream of audio that is to be played by one speaker. For example, stereo audio, consists of two channels. This option is useful for codecs that don’t have support for more than 2 channels.

Select a channel type in Audio Channels from the Audio menu. VLC media player provides four audio channels and they are:

1. Stereo – Refers to the reproduction of the sound in two channels using more than one speaker. If you use this option, you would feel as though the sound is played from all the directions. You can observe this in a regular home theatre with 5.1 or 6.1 speakers.
2. Left – You can observe this in a regular audio player with 2.1 speakers. If you select the Left option, the music is played only in the left speaker. The speaker on your right is automatically switched OFF.
3. Right - If you select the Right option, the music is played only in the speaker on your right side. The speaker on your left is automatically switched OFF.
4. Reverse Stereo – There are several applications that are used to reverse the stereo whereas VLC has an in-built feature to reverse the stereo. This option is useful if you want the audio to play in tandem with the video. You can use the Reverse Stereo option if you want to deliberately change the audio output.

Imagine that you are watching a video. In the video, a person walks on the left side but the sound is produced on the right speaker. You can correct this by selecting the Reverse Stereo option in VLC. Select the Reverse Stereo option and play the same scene in the video and observe the difference.

You can observe this with 2.1, 5.1 and 6.1 speakers.

Visualise Audio

Visualizations display splashes of colour and geometric shapes when audio is played.

The different visual effects available are Spectrometer, Scope, VU Meter, Spectrum and Goom.

Video tracks of the .asf, .avi, .divx, .dv, .mxf, .ogg, .gm, .ps, .ts, .vob, and .wmv formats are supported.

Playing a Video Track

You can play, disable or enable a video track.

1. Select Open File from the Media menu.
2. Select a video track and click on the Play button. The selected track is played.
3. To disable a track, select Disable under the Video Track from the Video menu. The selected track stops.
4. To play the same track, select the Track 1 option under Video Track from the Video menu. The selected track is played.

Loading Subtitle Tracks

A subtitle is a textual version of a movie’s dialogue. Subtitles 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, and .ssa are supported.

VLC can read subtitles for the media such as DVD, SVCD, OGM files, and Matroska (MKV) files.

Example finding a Shoutcast radio stream

This example was verified as working on 15 October 2008, using VLC 0.9.4 under Windows Vista. This needs reproducing by other people on other versions and other operating systems.

1. Ensure your firewall is set to allow the VideoLan program to make outgoing connections.

2. Click Tools then Preferences, click Interface and then click All under "Show settings". Then click the "-" next to "Playlist" in order to show the "Services discovery" submenu. If the shoutcast radio listings box is empty, click it so that a check-mark appears. The text field underneath should now show the word "shout". Click the Save button to save and close the Preferences window:



3. Restart VLC media player to make it take notice of the changed preferences.

4. On the VLC interface click Playlist, then click Show Playlist. Select the "Shoutcast Radio" in the left hand panel. If nothing appears in the righthand panel, try double-clicking "Shoutcast Radio" and waiting, it may take a few minutes the first time. After a while the righthand panel displays a long list of titles.



5. Scroll down the radio stations in the right-hand panel and select one. Click the mouse right button and click the "Play" item.



6. It may take some time for the connection to the radio station to establish (and it may fail if the station's outgoing streams are all occupied). When it does connect, VLC should start playing the audio stream from the station:



Example playing a known Shoutcast radio stream

Go to http://www.shoutcast.com/ and search for a radio station of your choice. On Windows, right-click your mouse over Shoutcast's "Tunein" button and click "Save Link As..." to save the playlist on your computer. Remember where you saved the playlist, rename it to something that makes sense.

At any time later, you can use VLC to open the saved playlist and listen to that radio station.

For example, to find a BBC World Service radio stream, use a browser to go to: http://www.shoutcast.com/directory/search_results.jsp?searchCrit=simple&s=bbc

One of the stations listed may be playing the World Service, if so move your mouse over the "TUNEIN!" webicon and click the right mouse button and click "Save Link As...", as described above.

Play from an acquisition card

This currently only possible on Linux and Windows. Open the File menu, and select "Open Capture Device..."

On Windows, supported cards include webcams, TV cards, acquisition cards... provided they come with directshow compatible drivers (Almost all acquisition cards do). You can choose the device to use for video and audio capture using the "Video device name" and "Audio device name" selectors. If your device doesn't appear in the list, try to select the "Refresh list" button. You can access the settings of your acquisition device by selecting the configure button. Options here depend on the driver of the device. You can select the "Device Proprieties" box if you want the configuration dialog box of every device to be displayed after having pressed the Ok button. Select the Tuner properties box to be prompted for tuner settings (PAL/NTSC standard, frequency...) for TV cards.

Adding items, saving and loading playlists

In the wxWidgets interface, the Manage menu allows you to append an item at the end of the playlist (its playback won't start immediately), to save the playlist as a M3U or PLS file, or to import a playlist file.

In the MacOS X interface, saving a playlist can be done using the Save Playlist... function in the File menu. To import a playlist file, open it the same way as any other media file, using the Quick Open File... menu item.

Sorting

In the wxWidgets interface, Sort allows you to sort the playlist according to several criteria, or to shuffle it. You can also sort by clicking the header of the column.

In the MacOS X interface, sorting can be done by clicking the header of the column matching the criteria you want to use for sorting.

Playlist modes

The playlist supports several playback modes.

In the wxWidgets interface, the toolbar contains three playlist mode buttons. They allow to enable random mode, to repeat the whole playlist or to repeat one item.

In the MacOS X interface, random mode can be enabled by selecting the Random box. A drop down menu allows you to enable playlist and item repeat modes.

Misc

Search

You also have a search tool. Enter a search string and hit search. The next item to match the string will be highlighted. Keep hitting Search to cycle between all matching items.

Moving items

In the wxWidgets interface, the Up and Down buttons at the bottom of the playlist window allow you to move an item. Select an item and use these buttons to move it.

In the MacOS X interface, you can easily move an item with the mouse, using drag-and-drop.

Contextual menu

By right-clicking or control-clicking an item, a contextual menu will appear, giving access to a number of functions (for example, play the item, disable it, delete it, or get info on it).

If you ask for info, an item info dialog box will appear. This dialog box also allows you to change the name, the author and the location of the item to play.

Subtitles

VLC supports many kinds of subtitles.

Media with included subtitles

Many types of media can have embedded subtitles. VLC can read subtitles for the following media:

• DVD
• SVCD
• OGM files
• Matroska (MKV) files

Subtitles are disabled by default. To enable them, go to the Video menu, and to Subtitles track. All available subtitles tracks will be listed. Select one to get the subtitles. Depending on the media, a description (language, for example) might be available for the track.

Select a subtitles track under Windows or Linux- needs verifying for 0.9

Select a subtitles track under MacOS X- needs verifying for 0.9

DVD and SVCD subtitles are merely images, so you won't be able to change anything for them. OGM and Matroska subtitles are rendered text, so you will be able to change several options.

Text rendering options can be changed in the Preferences. In the Modules section, text renderer subsection, open the freetype page. You can then set the font and its size. For the font, you have to select a font file. Under Windows, they can be found in C:\Windows\Fonts. Under MacOS X, they are in /System/Library/Fonts. Size can be set either relatively or as a number of pixels.

You need to restart your stream for the font modifications to take effect.

Subtitles files

While modern file formats like Matroska or OGM can handle subtitles directly, older formats like AVI can't. Therefore, a number of subtitles files formats have been created. You need two files: the video file and the subtitles files that only contains the text of the subtitles and timestamps.

VLC can handle these types of subtitles files:

• MicroDVD
• SubRIP
• SubViewer
• SSA
• Sami
• Vobsub (this one is quite special: it is not made from text but from images, which means that you can't change the fonts)

To open a subtitles file, use the Advanced Open dialog box (Menu File, Open file). Select your file by clicking on the Browse button. Then, check the Subtitle options checkbox and click on the Settings button.

Select a subtitles file under Windows or Linux- needs verifying for 0.9

You can then select the subtitles file by clicking the Browse button. You can also set a few options like character encoding, alignment and size. The delay option allows you to delay the subtitles against the video if they are not in sync. If they are not at the same speed, you might also want to adjust the subtitles framerate.

Note: For Vobsub subtitles, you need to select the .idx file, not the .sub file. Encoding, alignment and size won't have any effect for Vobsub subtitles.

Font can be changed as explained in the previous section.

Video and audio filters

VLC includes a system of filters that allow you to modify the audio and video.

Deinterlacement and Post Processing

VLC is able to deinterlace a video stream using different deinterlacement methods. Deinterlacement can be enabled in the Video menu, Deinterlacement menu item. The Blend methods gives the best results in most cases. The discardmethod is a less resource consuming alternative.

On some particular streams (MPEG 4, DIVX, XVID, Sorenson, etc.), some additional image filtering can be applied to the video before display, improving its quality in some cases. This can be enabled in the Video menu, Post processing menu item. Different levels of post processing can be chosen here. A higher level means more filtering.

Video filters

VLC features several filters able to change the video (distortion, brightness adjustment, motion blurring, etc.).

With the wxWidgets interface, filters can be easily enabled using the Extended GUI. In the Video tab, simply select the filters to enable. Image settings can be easily adjusted.

Video filters selection in the wxWidgets interface- needs verifying for 0.9

You can enable these filters through the Extended Controls panel on Mac OS X. Click on the triangle next to Video filters to select your filters or expand the Adjust Image section to change the contrast, hue, etc.

Video filters selection in the Mac OS X interface- needs verifying for 0.9

For better control, you need to go to the preferences. To select the filters to be enabled, go to Video, then to Filters. In the "video filter module" box, enter the names of the filters to enable, separated by semicommas. Filters will be applied in the selected order. Valid names are "clone", "wall", "transform", "adjust", "crop", "deinterlace", "distort", "motionblur" and "logo".

If you want to tune the behavior of these filters, go to Video, Filters, [your filter]. For each filter, you will find a short description and the options.

Audio filters

Equalizer

VLC features a 10-band graphical equalizer. You can display it by activating the advanced GUI on wxWidgets or by clicking the Equalizer button on the MacOS X interface.

The equalizer in the wxWidgets interface- needs verifying for 0.9

The equalizer in the MacOS X interface- needs verifying for 0.9

Presets are available in the Audio menu in wxWidgets, or in the Equalizer window in the MacOS X interface.

Other audio filters

At the moment, VLC features two other audio filters: a volume normalizer and a filter providing sound spatialization with a headphone. They can be enabled in the Audio tab of the extended GUI for the wxWidgets interface and in the Audio section of the Extended Controls panel of the Mac OS X interface.

For better control, you need to go to the preferences. To select the filters to be enabled, go to Audio, then to Filters. In the "audio filters" box, enter the names of the filters to enable, separated by commas. Valid names are "equalizer", "normvol" and "headphone".

If you want to tune the behavior of these filters, go to Audio, Filters, [your filter]. The equalizer and headphone filters can be tuned.

Snapshots (aka, screenshots)

There are two ways to take snapshots (i.e., screenshots or frame grabs) with VLC:

1. Go to Video -> Snapshot, or
2. Press the snapshot hotkey
   • Windows / Linux / Unix: Ctrl-Alt-s
   • Mac OS X: Command-Alt-s

When a snapshot is taken, it will briefly preview as a thumbnail with its filename and then fade away.

To change the hotkey, go to Preferences -> Interface -> Hotkeys settings. Check Advanced options, and set Take video snapshot.

Snapshot location, format and name

The snapshot location depends upon your operating system:

• Windows: My Documents\My Pictures\
• Linux / Unix: $(HOME)/.vlc/
• Mac OS X: Desktop/

The default format for snapshots is PNG, but this may be changed to JPEG. Also, the default name for snapshots is vlcsnap- followed by a timestamp that is not the time of the frame in the video you're viewing.

The location, format and name of snapshots may be changed in the Preferences. Also, you may substitute other text for vlcsnap- in the Video snapshot file prefix and you may choose to have snapshots numbered sequentially (i.e., 000001, 000002, 000003, and so on) instead of with a timestamp. As of version 0.9.0, you may even use variables in the text used for the filename. For example, $T (must be upper case) will insert the video's time code into the file name. If you were to change the prefix to Friends-$T- while watching a DVD of Friends, then the snapshot filenames would look something like this: Friends-00_05_21-00004.png . This indicates a snapshot taken at 5 minutes and 21 seconds into the video; and it was the number 00004 snapshot of the day.

For a full list of variables, please see Documentation:Play HowTo/Format String.

Hotkeys

Most of VLC functions are accessible using hotkeys.

The list of the available hotkeys and their functions can be retrieved and altered in the preferences panel of the player. In the wxWidgets interface, preferences are available in the "Settings" menu, "Preferences" menu item. In the MacOS X interface, open the "VLC" menu, and select "Preferences". Select the "Hot keys" panel in the dialog.

As of version 0.9, a list of hotkeys is presented in a drop-down window. To change one, double-click its name to select it. Then, press the new key that will trigger the specified action. Modifier keys (such as Control/Command and Alt) may also be used.

In earlier versions, several boxes give the list of modifiers for the hotkey. To trigger an action using a hotkey, you need to press simultaneously the keys corresponding to the different selected modifiers as well as the key set in the dropdown.

To change the binding of a hotkey, select or deselect boxes corresponding to the different modifiers, and change the key by using the drop-down menu. Select the Save button to apply the changes.

Basic troubleshooting

File does not play, only sound or only video

Maybe the file you are trying to read is not fully supported. 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 (View menu) and restart your stream. Look for error messages (red messages)

The wxWidgets messages window- needs verifying for 0.9

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 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")
