=== <span id="Disk_image"></span> Compact Disc (CD) Images ===
 +
If you have a [[CD-DA]] (audio CD), [[SVCD]], or [[VCD]] packaged inside a CD-image, in some cases [[VLC media player]] can play this without you having to mount it or extract it. You can simply choose ''Open file'' and pick the CD-image. For CD-image support VLC has to be [[compile]]d using libcdio (<code>--enable-libcdio</code>) and the various plugins which use libcdio need to be selected (<code>--enable-cddax</code>, <code>--enable-vcdx</code>). Some of these options may not be the default for your [[operating system]].
 +
 
 +
The kinds of Compact Disc formats supported are CDRWIN's ''BIN/CUE format'', cdrdao's ''TOC format'', and a limited set of Nero (NRG) formats.
  
=== Play DVD/SVCD/VCD iso's / Images ===
+
:''([[libcdio]] also supports ISO-9660 image reading, but at present there is no VLC access plugin which uses it. [[DVD]] images follow the UDF format and there is some UDF support through libcdio. It is possible that will get added in the future; volunteers are most welcome.)''
If you have a DVD/SVCD/VCD packaged inside an image/iso file vlc can play this without you having to mount it or extract it in anyway. You can simply chose open file and pick the iso file. This is true for the standard .iso and .img files, not if its some proprietary format which is specific to a certain program (For example NERO's .nrg)

=== How to enable/use subtitles ===
 +
Before you try to enable [[subtitle]]s make sure the subtitles you have are in a format that VLC can read! You can find the list of compatible subtitle formats [https://www.videolan.org/vlc/features.html here].<br />
 +
If VLC has detected any sort of subtitles available, you will be able to turn them on under the menu: ''Video → Subtitles track → Track 1''
 +
 +
Auto-detection of subtitle files uses a 'fuzzy' logic which you can specify. If this is wrongly specified you may end up with more subtitle file options than really exist or miss some that are provided. By default it loads any file in the expected directory if part of the video name is matched exactly. If you don't see the number of subtitle options you expect, you might want to allow more 'fuzziness' by changing the preference in ''Video → Subtitles → Subtitle auto-detection'' where help is available if you 'hover' over the field.
 +
 +
If you mainly use .srt or .sub subtitles you can automatically enable them when detected; set the ''Input/Codecs → Advanced → Choose subtitle track'' option to 0, which will automatically enable the subtitle track. You can also experiment with the ''Choose subtitle language'' option on the same page. It may require some experimenting but it is possible to have subtitles enabled automatically.
 +
 +
'''Note:''' On macOS, the ''Video → Subtitles track'' menu item is permanently disabled for some reason. You must manually specify the location of the subtitles file in the ''Subpictures'' pane of the [[preferences]].
 +
 +
Unfortunately the default font for .srt subtitles does not display Unicode characters&mdash;characters that are not shown include hexadecimal U+2011 (non-breaking-hyphen <code>&#x2011;</code>), U+2012 (figure dash <code>&#x2012;</code>) and U+2A2F (cross-product <code>&#x2A2F;</code>).
 +
 +
=== Playing Windows Media files ===
 +
VLC should be able to successfully play both audio and video in .wma and .wmv 1 and 2. For the newest version (wmv3) only the Windows version of VLC will be able to play it, since no [[open-source]] implementation of wmv3 has yet been made, VLC plays it by using the Windows API. [[DRM]]-crippled files, however, cannot be played with VLC on any operating system.

 +
=== Be remotely controlled ===
 +
VLC provides a series of interfaces which allow it to be controlled in various ways such as via telnet, a web browser, several iPhone apps, desktop widgets and more. See [[VLC HowTo#Remote_Control_for_VLC|VLC HowTo#Remote Control for VLC]].
 +
 +
=== Announce What's Playing to IRC ===
 +
Announce the currently playing track to mirc (an IRC client). This is often referred to as a "now playing" script.<br />
 +
One approach to get this functionality with VLC is with the [[HTTP interface]].<br />
 +
Using it you can create a simple file which will display "''Artist'' with the song ''Title'' from the album ''Album'' and the genre ''Genre''" inside a page in your browser. You can then pull that page from mirc with standard sockets and thereby use the text in a script in mirc. Below I will provide some VERY simple and very ugly examples on how you could use this. The examples are tested with VLC 0.8.5 and mirc 6.12. I can't guarantee the code will work with any other versions (although it most likely will).<br />
 +
Okay, so here we go.<br />
 +
You start by creating a test.html file in the http interface directory ("{{Path to VLC|windows|dir=y|q=n}}\http").<br />
 +
Paste the following on ONE line of the file or it will not work:
 +
 +
<pre>
 +
ANNOUNCE <vlc id="value" param1="'ARTIST' vlc_get_meta"/>
 +
with the song <vlc id="value" param1="'TITLE' vlc_get_meta"/>
 +
from the album <vlc id="value" param1="'ALBUM' vlc_get_meta"/>
 +
, The genre is <vlc id="value" param1="'Genre' vlc_get_meta"/>
 +
</pre>
 +
— or for streaming server info —
 +
<pre>
 +
ANNOUNCE <vlc id="value" param1="'TITLE' vlc_get_meta"/>
 +
with the song <vlc id="value" param1="'NOW_PLAYING' vlc_get_meta"/>
 +
</pre>
 +
 +
Remember to leave an empty line behind the actual line of code, vlc/mirc seems to want this.<br />
 +
Then you must create a script in mirc under remote (<kbd>Alt+R</kbd>) and paste in the following:
 +
 +
<pre>
 +
alias now {
 +
  sockopen vlc_meta_info 127.0.0.1 8082
 +
}
 +
 +
on *:SOCKOPEN:vlc_meta_info: {
 +
  sockwrite -n $sockname GET /test.html HTTP/1.1
 +
  sockwrite -n $sockname Host: localhost
 +
  ;sockwrite -n $sockname Connection: Keep-Alive
 +
  sockwrite -n $sockname $crlf
 +
  sockwrite -n $sockname $null
 +
}
 +
 +
on *:sockread:vlc_meta_info: {
 +
  if ($sockerr > 0) return
 +
  :nextread
 +
  sockread %temp
 +
  if ($sockbr == 0) return
 +
  if (%temp == $null) %temp = ---
 +
  if (ANNOUNCE isin %temp) {
 +
    %temp = $remove(%temp,ANNOUNCE )
 +
    describe $active is listening to %temp
 +
  }
 +
  goto nextread
  
Before you try to enabled subtitles make sure the subtitles you have is in a format that vlc can read! You can find the list of compatible subtitle formats http://www.videolan.org/vlc/features.html here].
+
  sockclose vlc_meta_info
If vlc have detected any sort of subtitles availeble, you will be able to turn them on under the menu: ''Video->Subtitles track->Track 1''
+
}
 +
</pre>
  
If you mainly use .srt subtitles or .sub, you can get them turned on automatically when found, if u set the ''Input/Codecs->Advanced->Chose Subtitle track'' to 0, it will automaticly turn on the subtitle track. You can also experiment with the ''Chose subtitle language'' on the same page. But if u experiment a bit with the settings u should be able to get subtitles turned on automatically.
+
A couple things you may want to change are the [[port]] number the HTTP interface listens on (that's the first line and [[port]] 8082 in my case) and the text ''is listening to'' to whatever you like.
  
=== Playing windows media files ===
+
That's pretty much it. You should enable the HTTP interface in VLC by default if you want to use this on a regular basis. This is done under [[preferences]] in ''Interface → Main interfaces''.
VLC should be able to succesfully play both audio and video in wma and wmv 1 and 2, for the newest version (wmv3) only the windows version of vlc will be able to play it, since no opensource implementation of wmv3 have been made so far, so the windows vlc plays it by using the windows api. DRM files however can not be played on any OS.
 
  
=== How to adjust picture brightness/colors/contrast.. ===
+
Then with all this done (and VLC restarted) you can type <code>/now</code> in mirc and it will display your currently playing track.
  
'''If you are using the wxwindows userinterface:'''
+
This was made for mp3 tracks, so if it doesn't work with other types of media let me know.<br />
 +
You can reach me at: jonas (at) vrt.dk<br />
 +
(I'm also regularly in the freenode videolan channel, nickname E-bola)
  
You can adjust the typical values to tweak the picture of your video source by turning on the extended GUI. This is done in the menu: ''Settings->Extended GUI''. That will give you some extended control options for the video picture as well as an equalizer for the audio.

You can ofcourse always simply find a link to a radiostream and then open it as you would any other network stream in vlc. But if u would like to browse a list of online radios, you can try the list of shoutcast radio stations vlc can download for you. First you need top open the playlist window: View->Playlist. Once you have the playlist window open chose: ''Manage->Service discovery->Shoutcast radio listings''. After 10 seconds or so the playlist should have become populated by radio station entries. You obviously require internet access for this to work! If you want the stations sorted alphabetically, you can chose: ''Sort->Sort by title''. Also note shoutcast have many thousands stream availeble, per default in 0.8.2 250 stations are downloaded, this can be changed in the preferences under: <u>Playlist->Service discovery->Shoutcast</u>. Note that the more stations u want to add, the longer delay u will see when the station list is downloaded parsed and added to the playlist. Also note you should see 2 "Folder nodes" in the playlist under shoutcast called Genres and bitrate where the stations will be listed under their respective areas. Note that most stations claim to be multi genre, so a station might be listed under both Top40, pop and rock.

This area of the wiki contains a list with some of the possibilities VLC media player gives you. It was made to help people better realize the potential VLC has. Some entries will simply mention the possibility, while others try to explain how to do it as well.

Mediaplayer

Compact Disc (CD) Images

If you have a CD-DA (audio CD), SVCD, or VCD packaged inside a CD-image, in some cases VLC media player can play this without you having to mount it or extract it. You can simply choose Open file and pick the CD-image. For CD-image support VLC has to be compiled using libcdio (--enable-libcdio) and the various plugins which use libcdio need to be selected (--enable-cddax, --enable-vcdx). Some of these options may not be the default for your operating system.

The kinds of Compact Disc formats supported are CDRWIN's BIN/CUE format, cdrdao's TOC format, and a limited set of Nero (NRG) formats.

(libcdio also supports ISO-9660 image reading, but at present there is no VLC access plugin which uses it. DVD images follow the UDF format and there is some UDF support through libcdio. It is possible that will get added in the future; volunteers are most welcome.)

How to enable/use subtitles

Before you try to enable subtitles make sure the subtitles you have are in a format that VLC can read! You can find the list of compatible subtitle formats here.
If VLC has detected any sort of subtitles available, you will be able to turn them on under the menu: Video → Subtitles track → Track 1

Auto-detection of subtitle files uses a 'fuzzy' logic which you can specify. If this is wrongly specified you may end up with more subtitle file options than really exist or miss some that are provided. By default it loads any file in the expected directory if part of the video name is matched exactly. If you don't see the number of subtitle options you expect, you might want to allow more 'fuzziness' by changing the preference in Video → Subtitles → Subtitle auto-detection where help is available if you 'hover' over the field.

If you mainly use .srt or .sub subtitles you can automatically enable them when detected; set the Input/Codecs → Advanced → Choose subtitle track option to 0, which will automatically enable the subtitle track. You can also experiment with the Choose subtitle language option on the same page. It may require some experimenting but it is possible to have subtitles enabled automatically.

Note: On macOS, the Video → Subtitles track menu item is permanently disabled for some reason. You must manually specify the location of the subtitles file in the Subpictures pane of the preferences.

Unfortunately the default font for .srt subtitles does not display Unicode characters—characters that are not shown include hexadecimal U+2011 (non-breaking-hyphen ), U+2012 (figure dash ) and U+2A2F (cross-product ).

Playing Windows Media files

VLC should be able to successfully play both audio and video in .wma and .wmv 1 and 2. For the newest version (wmv3) only the Windows version of VLC will be able to play it, since no open-source implementation of wmv3 has yet been made, VLC plays it by using the Windows API. DRM-crippled files, however, cannot be played with VLC on any operating system.

How to control the aspect ratio of the video

Transcluded from Change the aspect ratio

Graphical and command-line approaches are both possible. For all methods both decimals and width:height values may be given, so a fullscreen aspect ratio would be accepted as both 4:3 and 1.33 (lists of popular aspect ratios: Widescreen.org and Wikipedia).

For the Qt Interface: In the menu bar select ToolsPreferencesVideoForce Aspect Ratio.

As described in Documentation:Command line#Video_options --aspect-ratio can be given on the command-line. Unlike the graphical approach, this will not modify settings permanently.

Be remotely controlled

VLC provides a series of interfaces which allow it to be controlled in various ways such as via telnet, a web browser, several iPhone apps, desktop widgets and more. See VLC HowTo#Remote Control for VLC.

Announce What's Playing to IRC

Announce the currently playing track to mirc (an IRC client). This is often referred to as a "now playing" script.
One approach to get this functionality with VLC is with the HTTP interface.
Using it you can create a simple file which will display "Artist with the song Title from the album Album and the genre Genre" inside a page in your browser. You can then pull that page from mirc with standard sockets and thereby use the text in a script in mirc. Below I will provide some VERY simple and very ugly examples on how you could use this. The examples are tested with VLC 0.8.5 and mirc 6.12. I can't guarantee the code will work with any other versions (although it most likely will).
Okay, so here we go.
You start by creating a test.html file in the http interface directory ("%PROGRAMFILES%\VideoLAN\VLC\http").
Paste the following on ONE line of the file or it will not work:

ANNOUNCE <vlc id="value" param1="'ARTIST' vlc_get_meta"/>
 with the song <vlc id="value" param1="'TITLE' vlc_get_meta"/>
 from the album <vlc id="value" param1="'ALBUM' vlc_get_meta"/>
, The genre is <vlc id="value" param1="'Genre' vlc_get_meta"/>

— or for streaming server info —

ANNOUNCE <vlc id="value" param1="'TITLE' vlc_get_meta"/>
 with the song <vlc id="value" param1="'NOW_PLAYING' vlc_get_meta"/> 

Remember to leave an empty line behind the actual line of code, vlc/mirc seems to want this.
Then you must create a script in mirc under remote (Alt+R) and paste in the following:

alias now {
  sockopen vlc_meta_info 127.0.0.1 8082
}

on *:SOCKOPEN:vlc_meta_info: {
  sockwrite -n $sockname GET /test.html HTTP/1.1
  sockwrite -n $sockname Host: localhost
  ;sockwrite -n $sockname Connection: Keep-Alive
  sockwrite -n $sockname $crlf
  sockwrite -n $sockname $null
}

on *:sockread:vlc_meta_info: {
  if ($sockerr > 0) return
  :nextread
  sockread %temp
  if ($sockbr == 0) return
  if (%temp == $null) %temp = ---
  if (ANNOUNCE isin %temp) {
    %temp = $remove(%temp,ANNOUNCE )
    describe $active is listening to %temp
  }
  goto nextread

  sockclose vlc_meta_info
}

A couple things you may want to change are the port number the HTTP interface listens on (that's the first line and port 8082 in my case) and the text is listening to to whatever you like.

That's pretty much it. You should enable the HTTP interface in VLC by default if you want to use this on a regular basis. This is done under preferences in Interface → Main interfaces.

Then with all this done (and VLC restarted) you can type /now in mirc and it will display your currently playing track.

This was made for mp3 tracks, so if it doesn't work with other types of media let me know.

Streaming - client

Listen to online radio

Transcluded from VLC HowTo/Listen to online radio

For the Qt Interface on 3.0.6:

  1. If not already visible, open the playlist sidebar through ViewPlaylist
  2. Scroll down the sidebar, if necessary, to the section Internet
  3. Click the entry Icecast Radio Directory
  4. Select a listing
  5. Start listening

Streaming - server

VLM

VLM is the Video On Demand part of the VLC streaming server features. It lets you set up a bunch of entries, and then lets users ask for and receive those streams. It has A LOT of possibilities and I will try to cover them all here.

You can divide VLM entries into 2 general categories: VOD, and broadcast entries.
