'''M3U''' (''MP3 URL''<ref name="WinPlay3v20"/><ref name="Gnomie"/> or Moving Picture Experts Group Audio Layer 3 Uniform Resource Locator<ref>{{cite web |url=http://ftp6.nero.com/user_guides/mediahome/NeroMediaHome_Eng.pdf |title=Nero MediaHome 4 - Manual |author=Nero |archive-url=https://web.archive.org/web/20150905193735/http://ftp6.nero.com/user_guides/mediahome/NeroMediaHome_Eng.pdf |archive-date=2015-09-05 |url-status=live}}</ref> in full) is a computer file format for a multimedia [[Playlist|playlist]]. One common use of the M3U file format is creating a single-entry playlist file pointing to a [[Engineering:Streaming media|stream]] on the Internet.  The created file provides easy access to that stream and is often used in downloads from a website, for emailing, and for listening to [[Internet radio]].

Although originally designed for audio files, such as [[MP3]], it is commonly used to point media players to audio and video sources, including online sources. M3U was originally developed by [[Organization:Fraunhofer Society|Fraunhofer]] for use with their Winplay3 software,<ref>{{cite web|url=http://www.winamp.com/download/docs/index.jhtml?filenumber=120&language=english&layout=normal&prevlayout=normal|archive-url=https://web.archive.org/web/20020606035458/http://www.winamp.com/download/docs/index.jhtml?filenumber=120&language=english&layout=normal&prevlayout=normal|archive-date=2002-06-06|title=WINAMP.COM &#124; Winamp Documentation|date=June 6, 2002}}</ref> but numerous media players and software applications now support the format.

Careless handling of M3U playlists has been the cause of [[Vulnerability (computing)|vulnerabilities]] in many music players such as [[Software:VLC media player|VLC media player]],<ref>{{cite web |url=https://www.videolan.org/security/sa0804.html |year=2008 |title=VideoLAN-SA-0804 (CVE-2007-6683) |quote=Arbitrary file overwrite and other abuses through M3U parser and browsers plugins.}}</ref> [[Software:ITunes|iTunes]],<ref>{{cite web|url=http://cve.circl.lu/cve/CVE-2012-0677|title=CVE-2012-0677: Heap-based buffer overflow in Apple iTunes before 10.6.3 allows remote attackers to execute arbitrary commands|website=cve.circl.lu}}</ref> [[Software:Winamp|Winamp]],<ref>{{cite web|url=https://cve.report/CVE-2000-0624/|title=CVE-2000-0624: Buffer overflow in Winamp 2.64 and earlier allows remote attackers to execute arbitrary commands via a long #EXTINF: ext|website=www.cvedetails.com}}</ref> and many others.<ref>{{cite web |url=https://packetstormsecurity.com/search/?q=m3u&s=files |title=247 search results |work=[[Packet Storm]] |access-date=2018-01-23}}</ref>

==File format==
There is no formal specification for the M3U format; it is a de facto standard.

An M3U file is a [[Plain text|plain text]] file that specifies the locations of one or more media files. The file is saved with the "m3u" [[Filename extension|filename extension]] if the text is encoded in the local system's default non-Unicode encoding (e.g., a Windows codepage), or with the "m3u8" extension if the text is [[UTF-8]] encoded.<ref>{{cite web |url=https://www.nero.com/enu/wGlobal/content/elements/sysreq/n2015pla-sysreq.php?viewmode=nElement&vlang=us |title=Nero 2015 Platinum - System Requirements |quote=MP3 URL + UTF-8 (M3U8)}}</ref>

Each entry carries one specification.  The specification can be any one of the following:
* an ''absolute local pathname''; e.g., C:\My Music\Heavysets.mp3
* a ''local pathname'' relative to the M3U file location; e.g. Heavysets.mp3
* a [[URL]]

Each entry ends with a line break which separates it from the following one. Furthermore, some devices only accept line breaks represented as <code>CR&nbsp;LF</code>, but do not recognize a single <code>LF</code>.

===Extended M3U===
The M3U file can also include comments, prefaced by the "#" character. In '''extended M3U''', "#" also introduces extended M3U directives which are terminated by a colon ":" if they support parameters.

Apple used the extended M3U format as a base for their [[HTTP Live Streaming]] (HLS)<ref name=hls>{{cite web|url=https://developer.apple.com/documentation/http_live_streaming/about_the_common_media_application_format_with_http_live_streaming|title=About the Common Media Application Format with HTTP Live Streaming &#124; Apple Developer Documentation|website=developer.apple.com}}</ref> which was documented in an Independent Submission Stream RFC in 2017 as RFC 8216.<ref name="rfc8216">{{cite book|chapter-url=https://tools.ietf.org/html/rfc8216#section-4.3|title=RFC 8216: HTTP Live Streaming|journal=Request for Comments (RFC) Pages - Test|chapter=4.3 Playlist Tags|publisher=RFC Editor|author1=R.

Some tags only apply to the former type and some only to the latter type of playlist, but they all begin with <code>#EXT-X-</code>.

===M3U8===
The [[Unicode]] version of M3U is M3U8, which uses [[UTF-8]]-encoded characters. M3U8 files are the basis for the [[HTTP Live Streaming]] (HLS) format originally developed by [[Company:Apple Inc.|Apple]] to stream video and radio to [[Software:IOS|iOS]] devices, and which is now a popular format for adaptive streaming in general.

The 2015 proposal for the HLS playlist format uses UTF-8 exclusively and does not distinguish between the "m3u" and "m3u8" file name extensions.<ref name="HLSdraft">{{cite web|url=https://tools.ietf.org/html/draft-pantos-http-live-streaming-17.html|title=HTTP Live Streaming|first1=Roger|last1=Pantos|first2=William|last2=May|website=tools.ietf.org}}</ref>

==Internet media types==

The only Internet media type registered for M3U and M3U8 is <code>application/vnd.apple.mpegurl</code>, registered in 2009 and only referring to the playlist format as used in HLS applications.<ref>{{cite web|url=https://www.iana.org/assignments/media-types/media-types.xhtml#audio|title=Media Types|website=www.iana.org}}</ref><ref>{{cite web|url=https://www.iana.org/assignments/media-types/application/vnd.apple.mpegurl |title=Data |publisher=iana |access-date=2019-10-21}}</ref>

The current proposal for the HLS playlist format acknowledges two media types which it treats as equivalent: <code>application/vnd.apple.mpegurl</code> and <code>audio/mpegurl</code>.<ref name="HLSdraft"/> Likewise, these are the two types recommended for HLS use by Microsoft.<ref name="Win10"/>

For non-HLS applications, no media types were standardized or registered with the [[Organization:Internet Assigned Numbers Authority|IANA]], but a number of media types are nonetheless associated with the historical and ongoing use of the M3U and M3U8 formats for general playlists:
* <code>application/mpegurl</code>
* <code>application/x-mpegurl</code>
* <code>audio/mpegurl</code>
* <code>audio/x-mpegurl</code><ref name="WinPlay3v20">{{cite web |url=http://www.iis.fhg.de/audio |archive-url=https://web.archive.org/web/19970606171426/http://www.iis.fhg.de/departs/amm/layer3/winplay3/ |url-status=dead |archive-date=1997-06-06 |title=WinPlay3 - Windows real-time ISO/MPEG Audio Layer 3 Player |date=1996-10-30 |author=Fraunhofer Gesellschaft, Fraunhofer Institut für Integrierte Schaltungen-A |access-date=2018-01-21 }}</ref><ref name="Gnomie">{{cite web |url=https://lockergnome.com/mp3/article14.html |first=Matt |last=Gruett |title=M3U FILES AND STREAMING |archive-url=https://web.archive.org/web/20010426110118/https://lockergnome.com/mp3/article14.html |archive-date=2001-04-26 |url-status=dead |work=LockerGnome}}</ref>

These types, plus <code>application/vnd.apple.mpegurl</code> and <code>application/vnd.apple.mpegurl.audio</code>, are supported for HLS applications by (for example)  Microsoft's [[Software:Windows 10|Windows 10]]<ref name="Win10">{{cite web|url=https://blogs.msdn.microsoft.com/ie/2015/01/29/simplified-adaptive-video-streaming-announcing-support-for-hls-and-dash-in-windows-10/|title=Simplified Adaptive Video Streaming: Announcing support for HLS and DASH in Windows 10 – IEBlog|website=blogs.msdn.microsoft.com}}</ref> and [[Software:Internet Explorer|Internet Explorer]] 9,<ref>{{cite web|url=https://developer.mozilla.org/en-US/docs/Web/API/HTMLVideoElement|title=HTMLVideoElement|website=MDN Web Docs}}</ref> and LG's [[Software:WebOS|WebOS]].<ref>{{Cite web |url=http://developer.lge.com/webOSTV/api/supported-standard-web-api/html5-standard/audio-video/ |title=::: LG Developer &#124; Audio & Video ::: |access-date=2015-12-12 |archive-url=https://web.archive.org/web/20151222151959/http://developer.lge.com/webOSTV/api/supported-standard-web-api/html5-standard/audio-video/ |archive-date=2015-12-22 |url-status=dead }}</ref>

==Examples==

;Example 1
This is an example of an extended M3U file on the Windows platform. Sample.mp3 and Example.ogg are the media files. 123 and 321 are the lengths in seconds.<ref>{{cite web|url=http://www.clearone.com/uploads/resource/030055_Creating_Playlists_to_Work_with_the_Streaming_Music_Manager-0.pdf|title=DigiLinX Application Note - Creating Playlists to Work with the Streaming Music Manager|date=2007-10-05}}</ref> A length of -1 or 0 may be used when the media file is a streaming file, as there is no actual, predefined length value. The value after the length is the title to be shown, which is generally the same as the location of the file which is on the second line. On the [[Software:MacOS|macOS]] and [[Software:Linux|Linux]] platforms, Unix paths are used.
 #EXTM3U
  
 #EXTINF:123, Sample artist - Sample title
 C:\Documents and Settings\I\My Music\Sample.mp3
  
 #EXTINF:321,Example Artist - Example title
 C:\Documents and Settings\I\My Music\Greatest Hits\Example.ogg

;Example 2
This example shows how to create an m3u file linking to a specified directory (for example, a [[Engineering:USB flash drive|flash drive]], or CD-ROM). The m3u file should contain only one string: the path to the directory. After starting, the media player will play all contents of the directory:
 C:\Music

;Example 3
Here is another example, using relative format. The M3U file is placed in the same directory as the music, and directories must be preserved when moving the playlist to another device if subdirectories are used. This method is more flexible, as it does not rely on the file path staying the same.

This is the same file as above, saved as sample.m3u in C:\Documents and Settings\User\My Music\
 #EXTM3U
  
 #EXTINF:123, Sample artist - Sample title
 Sample.mp3
  
 #EXTINF:321,Example Artist - Example title
 Greatest Hits\Example.ogg

This format in an M3U allows copying to another device for playback. All files and directories referred to must also be copied.

;Example 4
Here is a mixed example:
 Alternative\Band - Song.mp3
 Classical\Other Band - New Song.mp3
 Stuff.mp3
 D:\More Music\Foo.mp3
 ..\Other Music\Bar.mp3
 <nowiki>http://www.example.com:8000/Listen.mp3</nowiki>
 <nowiki>http://www.example.com/~user/Mine.mp3</nowiki>

Notes:
* Alternative and Classical are sub-directories of the directory that this playlist is stored in.
* "Song" and "New Song" are in sub-directories of the directory that this playlist is stored in.
* "Stuff" is in the same directory that the playlist is stored in.
* "Foo" is in the specified (Windows) volume and directory, which may or may not be the same directory the playlist is in.
* "Bar" is in a different directory at the same level as the playlist directory. The double-dots reference the parent directory of the playlist directory, then into the sub-directory "Other Music" to reach "Bar".
* "Listen" is a Shoutcast stream.
* "Mine" is an MP3 stored on a web server.

;Example 5

References to other M3U playlists, for example, are generally not well-supported.
