# node-m3u



A node.js module for creating m3u / m3u8 files. Supported dialects are [m3u][],

[extended m3u][] and [http live streaming m3u][].



[m3u]: http://en.wikipedia.org/wiki/M3U

[extended m3u]: http://en.wikipedia.org/wiki/M3U#Extended_M3U_directives

[http live streaming m3u]:http://tools.ietf.org/html/draft-pantos-http-live-streaming



## Current Status



This module is still new, but I'm going to use it in production over at

[transloadit.com][] next.



[transloadit.com]: http://transloadit.com/



## Installation



    npm install m3u



## Usage



The default `Writer` class can be used to create basic m3u files:



    var writer = require('m3u').writer();



    // A comment.

    writer.comment('I am a comment');



    // An empty line.

    writer.write(); // blank line



    // A playlist item, usually a path or url.

    writer.file('foo.mp3');



    console.log(writer.toString());



The `ExtendedWriter` supports all methods of the normal `Writer`, as well as

additional capabilities defined by the extended m3u format.



    var writer = require('m3u').extendedWriter();



    // Adds a playlist item preceeded by an optional EXTINF tag for the duration.

    // and title of the item.

    writer.file('bar.mp3');

    writer.file('bar.mp3', 23);

    writer.file('bar.mp3', 23, 'Artist - Title');



    console.log(writer.toString());



The `HttpLiveStreamingWriter` supports all methods of the `ExtendedWriter`, as

well as additional capabilities defined by Apple:



    var writer = require('m3u').httpLiveStreamingWriter();



    // EXT-X-TARGETDURATION: Maximum media file duration.

    writer.targetDuration(10);



    // EXT-X-MEDIA-SEQUENCE: Sequence number of first file (optional).

    // (optional)

    writer.mediaSequence(0)



    // EXT-X-PROGRAM-DATE-TIME: The date of the program's origin, optional.

    // (optional)

    writer.programDateTime('2011-04-11T21:24:06Z');



    // EXT-X-ALLOW-CACHE: Set if the client is allowed to cache this m3u file.

    // (optional)

    writer.allowCache(true);

    writer.allowCache(false);



    // EXT-X-PLAYLIST-TYPE: Provides mutability information about the m3u file.

    // (optional)

    writer.playlistType('EVENT');

    writer.playlistType('VOD');



    // EXT-X-ENDLIST: Indicates that no more media files will be added to the m3u file.

    // (optional)

    writer.endlist();



    // EXT-X-VERSION: Indicates the compatibility version of the Playlist file.

    // (optional)

    writer.version(3);



    // Adds a playlist as the next item preceeded by an EXT-X-STREAM-INF tag.

    writer.playlist('another.m3u', {

      bandwidth: 3000000, // required

      programId: 1,

      codecs: ['avc1.42001e', 'mp4a.40.34'],

      resolution: '640x480',

    });



    // EXT-X-DISCONTINUITY: Indicates that the player should expect the next video segment to be a different resolution or have a different audio profile than the last.

    writer.discontinuity();



    console.log(writer.toString());



## Todo



I don't have plans for more features at this point, except bug fixes.



## Contributing



Stuff I probably won't have time to do myself, and would love to get patches for:



* Implement the ability to read m3u files

* Support node.js's writeable stream interface for the writers

* `HttpLiveStreamingWriter#key()` (EXT-X-KEY)

* Support JS date objects for `HttpLiveStreamingWriter#programDateTime()`
