{{xiph|XSPF}}
'''XSPF''', pronounced "spiff", is a [[playlist]] in [[XML]] format, which is supported by [[Xiph]]. It is a free and open format so can be easily, freely used for sharing playlists.

== Sample ==
A very simple document looks like this:
<syntaxhighlight lang="xml">
 <?xml version="1.0" encoding="UTF-8"?>
  <playlist version="1" xmlns="http://xspf.org/ns/0/">
     <trackList>
         <track><location>file:///mp3s/song_1.mp3</location></track>
         <track><location>file:///mp3s/song_2.mp3</location></track>
         <track><location>file:///mp3s/song_3.mp3</location></track>
     </trackList>
  </playlist>
</syntaxhighlight>

== Compatibility ==
{{compat}}

== VLC Extensions ==
XSPF supports extensions to allow applications to add special data. These extensions can appear in the following entries:
* playlist
* track

The extension format is defined in the namespace <code>xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/"</code>:
<syntaxhighlight lang="xml">
 <playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/">
  ...
  <extension application="http://www.videolan.org/vlc/playlist/0">
   ...
  </extension>
 </playlist>
</syntaxhighlight>

Currently, extensions support the following elements:
* vlc:node
* vlc:item
* vlc:id
* vlc:option

The extensions vlc:node and vlc:item are used to specify how to display the playlist tree, which is not supported by standard XSPF.

=== vlc:node ===
This element will be displayed as a node in the playlist. It appears as an extension of the '''playlist''' block (under playlist/extension). Only its name can be specified:
<syntaxhighlight lang="xml">
 <vlc:node title="Node title">
  [list of vlc:item or vlc:node]
 </vlc:node>
</syntaxhighlight>

=== vlc:item ===
This element represents a playlist item (not a node). It appears as an extension of the '''playlist''' block (under playlist/extension). It contains only a track id (see below, vlc:id):
<syntaxhighlight lang="xml">
 <vlc:item tid="42" />
</syntaxhighlight>

=== vlc:id ===
This element specifies a track's id. It appears as an extension of the '''track''' block (under playlist/trackList/track/extension).
<syntaxhighlight lang="xml">
 <vlc:id>42</vlc:id>
</syntaxhighlight>
The value of the id corresponds to the value of the attribute tid of vlc:item.
Note that each vlc:id has to be different, per entry, or it will not show them all.

=== vlc:option ===
This element allows you to add options to the input item. It appears as an extension of the '''track''' block (under playlist/trackList/track/extension).
<syntaxhighlight lang="xml">
 <vlc:option>option-name</vlc:option>
</syntaxhighlight>
Or, if the option has a value:
<syntaxhighlight lang="xml">
 <vlc:option>option-name=option-value</vlc:option>
</syntaxhighlight>

=== Example of XSPF with VLC extensions ===

Let's summarize these as an example.  This one shows passing VLC options per specified entry in the playlist.
<syntaxhighlight lang="xml">
 <?xml version="1.0" encoding="UTF-8"?>
 <playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/">
    <title>Playlist</title>
    <location>D:/media/example.xspf</location>
    <trackList>
        <track>
            <title>DVD seconds 42 to 45 muted</title>
            <location>dvd://d:\@1</location>
            <extension application="http://www.videolan.org/vlc/playlist/0">
                <vlc:id>3</vlc:id>
                <vlc:option>start-time=42</vlc:option>
                <vlc:option>stop-time=45</vlc:option>
                <vlc:option>no-audio</vlc:option>
                <vlc:option>some-option=100</vlc:option>
            </extension>
        </track>
        <track>
            <title>DVD seconds 49-55 unmuted (normal)</title>
            <location>dvd://d:\@1</location>
            <extension application="http://www.videolan.org/vlc/playlist/0">
                <vlc:id>4</vlc:id>
                <vlc:option>start-time=49</vlc:option>
                <vlc:option>stop-time=55</vlc:option>
            </extension>
        </track>
    </trackList>
 </playlist>
</syntaxhighlight>
Here is an example that shows how you can have it show nested entries within the playlist window:
<syntaxhighlight lang="xml">
 <?xml version="1.0" encoding="UTF-8"?>
 <playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/">
     <title>Playlist</title>
     <location>D:/media/example.xspf</location>
     <trackList>
         <track>
             <title>Track 1</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>0</vlc:id>
             </extension>
             
         </track>
         <track>
             <title>Track 2</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>1</vlc:id>
             </extension>
         </track>
         <track>
             <title>Track 3</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>2</vlc:id>
             </extension>
         </track>
         <track>
             <title>Track 4</title>
             <location>dvd://e:\@1</location>
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>3</vlc:id>
                 <vlc:option>my-option=100</vlc:option>
                 <vlc:option>start-time=42</vlc:option>
                 <vlc:option>stop-time=45</vlc:option>
                 <vlc:option>no-audio</vlc:option>
             </extension>
         </track>
     </trackList>
     <extension application="http://www.videolan.org/vlc/playlist/0">
         <vlc:node title="Node 1">
             <vlc:item tid="0" />
             <vlc:item tid="1" />
             <vlc:node title="Node 2">
                 <vlc:item tid="2" />
                 <vlc:item tid="3" />
             </vlc:node>
         </vlc:node>
     </extension>
 </playlist>
</syntaxhighlight>

This playlist example will be displayed as:
 Playlist
 `- Node 1
    |- Track 1
    |- Track 2
    `- Node 2
       |- Track 3
       `- Track 4

The input for ''Track 4'' will be created with the option ''my-option'' set to 42.

There are many advantages to using XML as the format.

== Unsafe operations ==
Some operations, like setting volume, setting sout destination, etc. are deemed "unsafe" to be in the playlist, so you'll have to add those settings to the command line instead.
You'll get the error message: 
'''unsafe option "sout-audio" has been ignored for security reasons)''' or the like.
