Documentation

M3U8Parser makes it easy to read, edit and create a m3u8 file.

M3U8Parser does not try to validate your file, it's your responsability to follow RFC.
Require .netstandard2.0 / .net6

Usage:

Read a file and edit it

    // Load a file
    var masterPlaylist = MasterPlaylist.LoadFromFile("master.m3u8");

    // Example, list all stream uri
    foreach(var stream in masterPlaylist.Streams)
    {
        Console.WriteLine("Uri:" + stream.Uri);
    }
    
    // Delete CLOSED-CAPTIONS type EXT-X-MEDIA
    masterPlaylist.Medias.RemoveAll(m => m.Type.Equals(MediaType.CloseCaptions));

Or your can create a master file

    var masterPlaylist = new MasterPlaylist(hlsVersion: 4);

    // Add EXT-X-MEDIA
    masterPlaylist.AddMedia(new Media
    {
        Default = true,
        AutoSelect = true,
        Language = "eng",
        Name = "English",
        Type = MediaType.Audio,
        GroupId = "audio"
    });

    // Add another EXT-X-MEDIA but from text, yes it works!

    var mediaWithDv = new Media("#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID=\"audio\",NAME=\"English DV\",LANGUAGE=\"eng\",AUTOSELECT=YES,DEFAULT=NO");
    mediaWithDv.Characteristics = "public.accessibility.describes-video";

    masterPlaylist.AddMedia(mediaWithDv);

    // Add EXT-X-STREAM
    masterPlaylist.AddStream(new StreamInf()
    {
        Codecs = "avc1.4d401f,mp4a.40.2",
        Bandwidth = 900000,
        Uri = "v0.m3u8"
    });
    
    masterPlaylist.AddStream(new StreamInf()
    {
        Codecs = "avc1.4d401f,mp4a.40.2",
        Bandwidth = 1000000,
        Uri = "v1.m3u8"
    });

This code should produce the following master playlist:

#EXTM3U
#EXT-X-VERSION:4

#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="English",LANGUAGE="eng",AUTOSELECT=YES,DEFAULT=YES
#EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID="audio",NAME="English DV",LANGUAGE="eng",AUTOSELECT=YES,DEFAULT=NO,CHARACTERISTICS="public.accessibility.describes-video"

#EXT-X-STREAM-INF:BANDWIDTH=900000,CODECS="avc1.4d401f,mp4a.40.2"
v0.m3u8
#EXT-X-STREAM-INF:BANDWIDTH=1000000,CODECS="avc1.4d401f,mp4a.40.2"
v1.m3u8
