General interface description
VLC has several interfaces: a cross-platform interface, for Windows and GNU/Linux, called wxWidgets, a MacOS X native interface and a skinnable interface for Windows and GNU/Linux.
Windows and GNU/Linux
This is the default interface on Windows and GNU/Linux (the screenshot is done on GNU/Linux, but it would look quite the same on Windows.
The wxWidgets interface
This interface also features an Extended GUI which contains many additional features. To display or hide it, go to the Settings menu and click Extended GUI.
The wxWidgets interface with extended GUI
Native Mac OS X (Cocoa)
This is the default interface on Mac OS X.
The Mac OS X interface
This interface features an Extended GUI as well. It is called "Extended Controls" and can be opened through the Window-menu.
The Mac OSX interface with with the extended controls panel
Simple play
Play a file
To open a file, open the File menu, and select the Quick Open File menu item. An Open File dialog box will appear. Select the file you want to open, and select Open. VLC will start playing the selected file.
An alternative is to Drag'n'Drop your file on the VLC main interface or playlist window from the file explorer (Finder on MacOS X).

Play a CD/DVD/VCD
To Play a CD, VCD or a DVD, open the File menu, and select the Open Disc... menu item. In the Open Disk Dialog Box, select the type of media (DVD, VCD or Audio CD). When reading a DVD, you can enable DVD menus by selecting the DVD (menus) Disc type in the wxWidgets Interface. In the MacOS X interface, this can be done by selecting the "Use DVD menus" dialog box.
You can select the drive from which the media should be read by giving the appropriate drive letter or device name in the "Device Name" text input. This should be autodetected on MacOS X.
If you want to start the DVD or VCD playback from a given title and chapter instead of from the beginning, you can set it using the Title and Chapter selectors.
You can start playback by selecting the Ok button.

Play a network stream (WebRadio, WebTV, ...)
To open a network stream, open the "File" menu and select the "Open Network Stream" menu item.
- To open a UDP unicast stream, select UDP/RTP, and set the appropriate UDP port in the selector (it is 1234 for streams sent by a VLC or VLS server).
- To open a UDP multicast stream, select UDP/RTP multicast. Give the address of the multicast group in the "Address" text input, and select the appropriate UDP port.
- To open a stream sent over http (Webradios, WebTVs, Shoutcast, Icecast...), ftp, or mms (Microsoft Media Server), select "HTTP/FTP/MMS", and give the corresponding complete URL, (such as http://live.stream.org:8080/live or mms://live.ms.stream.net:8080/live.asf) in the corresponding text input. This also the way to open a RTSP stream with the MacOS X interface.
- To open a RTSP stream (sent by Darwin Streaming Server, VLC, etc), in the wxWidgets interface, select "RTSP" and give the URL in the text input.
You can start playback by selecting the Ok button.
If you get some stuttering during playback, you can try to increase the size of the read buffer. This can be done in the Open Network Stream dialog box, by selecting the Caching box. You can then choose the amount time (in milliseconds) VLC should store data in its buffer before starting playback.

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. The Advanced options... button allows to select some further settings useful in some rare cases, such as the chroma of the input (the way colors are encoded) and the size of the input buffer.

On Linux, supported cards include webcams, TV cards, acquisition cards, provided they are supported by the Video4Linux architecture. Haupaugge PVR 250/350 cards are also supported, using the IVTV drivers.
- For Video4Linux devices, you can set the name of the video and audio devices using the "Video device name" and "Audio device name" text inputs. The "Advanced options..." button allows to select some further settings useful in some rare cases, such as the chroma of the input (the way colors are encoded) and the size of the input buffer.
The Open Video4Linux dialog- wxWidgets interface
- To use a Hauppauge PVR card, select the PVR tab in the "Open" dialog box. Use the "Device" text input to set the device of the card you want to use. You can set the Norm of the tuner (PAL, SECAM or NTSC) by using the "Norm" Drop Down. The Frequency selector allows you to set the frequency of the tuner (in kHz), the bitrate selector to set the bitrate of the resulting encoded stream (in bit/s). The "Advanced Options button allows to set some more settings, such as the size of the encoded video (in pixels), its framerate (in frame per second), the interval between 2 key frames, etc.
After having set all the required parameters, you can start the capture by selecting the "Ok" button.

<sect1><title>Using subtitles</title>
<para>VLC supports many kinds of subtitles.</para>
<sect2><title>Media with included subtitles</title>
<para>Many types of media can have embedded subtitles. VLC can read subtitles for the following media:</para>
<itemizedlist> <listitem><para>DVD</para></listitem> <listitem><para>SVCD</para></listitem> <listitem><para>OGM files</para></listitem> <listitem><para>Matroska (MKV) files</para></listitem> </itemizedlist>
<para>Subtitles are disabled by default. To enable them, go to the <emphasis>Video</emphasis> menu, and to <emphasis>Subtitles track</emphasis>. 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.</para>

</mediaobject>
<para>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.</para>
<para>Text rendering options can be changed in the Preferences. In the <emphasis>Modules</emphasis> section, <emphasis>text renderer</emphasis> subsection, open the <emphasis>freetype</emphasis> 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 <emphasis>C:\Windows\Fonts</emphasis>. Under MacOS X, they are in <emphasis>/System/Library/Fonts</emphasis>. Size can be set either relatively or as a number of pixels.</para>
<para>You need to restart your stream for the font modifications to take effect.</para>
</sect2>
<sect2><title>Subtitles files</title>
<para>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.</para>
<para>VLC can handle these types of subtitles files:</para>
<itemizedlist> <listitem><para>MicroDVD</para></listitem> <listitem><para>SubRIP</para></listitem> <listitem><para>SubViewer</para></listitem> <listitem><para>SSA</para></listitem> <listitem><para>Sami</para></listitem> <listitem><para>Vobsub (this one is quite special: it is not made from text but from images, which means that you can't change the fonts)</para></listitem> </itemizedlist>
<para>To open a subtitles file, use the Advanced Open dialog box (Menu File, Open file). Select your file by clicking on the <emphasis>Browse</emphasis> button. Then, check the <emphasis>Subtitle options</emphasis> checkbox and click on the Settings button.</para>
<mediaobject>

</mediaobject>
<para>You can then select the subtitles file by clicking the <emphasis>Browse</emphasis> 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.</para>
<note><para>For Vobsub subtitles, you need to select the <userinput>.idx</userinput> file, not the <userinput>.sub</userinput> file</para> <para>Encoding, alignment and size won't have any effect for Vobsub subtitles.</para> </note>
<para>Font can be changed as explained in the previous section.</para>

</sect1>
<sect1><title>Video and audio filters</title>
<para>VLC includes a system of <emphasis>filters</emphasis> that allow you to modify the audio and video.</para>
<sect2><title>Deinterlacement and Post Processing</title>
<para>VLC is able to deinterlace a video stream using different deinterlacement methods. Deinterlacement can be enabled in the <emphasis>Video</emphasis> menu, <emphasis>Deinterlacement</emphasis> menu item. The <emphasis>Blend</emphasis> methods gives the best results in most cases. The <emphasis>discard</emphasis> method is a less resource consuming alternative.</para>
<para>On some particular streams (MPEG 4, DIVX, XVID, Sorenson, ...), some additional image filtering can be applied to the video before display, improving its quality in some cases. This can be enabled in the <emphasis>Video </emphasis> menu, <emphasis>Post processing</emphasis> menu item. Different levels of post processing can be chosen here. A higher level means more filtering.</para>
</sect2>
<sect2><title>Video filters</title>
<para>VLC features several filters able to change the video (distortion, brightness adjustment, motion blurring, ...).</para>
<para>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.</para>

<sect3><title>Other audio filters</title>
<para>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.</para>
<para>For better control, you need to go to the preferences. To select the filters to be enabled, go to <emphasis>Audio</emphasis>, then to <emphasis>Filters</emphasis>. In the "audio filters" box, enter the names of the filters to enable, separated by commas. Valid names are "equalizer", "normvol" and "headphone".</para>
<para>If you want to tune the behavior of these filters, go to <emphasis>Audio, Filters, [your filter]</emphasis>. The equalizer and headphone filters can be tuned.</para>

<sect1><title>Basic troubleshooting</title>
<note><para>This is very incomplete</para></note>
<sect2><title>File does not play, only sound or only video</title>
<para>Maybe the file you are trying to read is not fully supported. VLC does not use the codec packs 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).</para>
<para>To find out, open the Messages Window (View menu) and restart your stream. Look for error messages (red messages)</para>

<para>In this example, the file contains a IV41 video stream, a codec that is not supported by VLC.</para>
<para>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.</para>

<sect2><title>Weird VLC behavior ("stopped working")</title>
<para>A very common thing is a bogus preferences file. Don't hesitate to delete it if problems appear suddenly. You will find in the FAQ details on <ulink url="http://www.videolan.org/doc/faq/en/index.html#id2470084">how to delete your preferences file</ulink>.</para>
</sect2>
<sect2><title>Computer crashes / Video is corrupted</title>
<para>Another common problem is buggy video drivers. Try upgrading them from the website of your video card's manufacturer.</para>
<para>Also, you can try disabling Overlay (Preferences/General/Video, untick "Overlay video output")</para>
