    License: MIT Coverage Status Slack

    Node library to create an HLS by truncating the length of an HLS VOD.

    Installation

    npm install --save @eyevinn/hls-truncate
    

    Usage

    The code below shows an example on how an HLS VOD of 30 seconds can be truncated into a new VOD of approx 4 seconds.

    const hlsVod = new HLSTruncateVod('http://testcontent.eyevinn.technology/slates/30seconds/playlist.m3u8', 4);
    hlsVod.load()
    .then(() => {
      const mediaManifest = hlsVod.getMediaManifest(4928000);
      console.log(mediaManifest);
    });
    

    What this library does can be illustrated by this simplified example below.

    Consider the following:

    #EXTM3U
    #EXT-X-TARGETDURATION:3
    #EXT-X-ALLOW-CACHE:YES
    #EXT-X-PLAYLIST-TYPE:VOD
    #EXT-X-VERSION:3
    #EXT-X-INDEPENDENT-SEGMENTS
    #EXT-X-MEDIA-SEQUENCE:1
    #EXTINF:3.000,
    segment1_0_av.ts
    #EXTINF:3.000,
    segment2_0_av.ts
    #EXTINF:3.000,
    segment3_0_av.ts
    #EXTINF:3.000,
    segment4_0_av.ts
    #EXTINF:3.000,
    segment5_0_av.ts
    #EXTINF:3.000,
    segment6_0_av.ts
    #EXTINF:3.000,
    segment7_0_av.ts
    #EXTINF:3.000,
    segment8_0_av.ts
    #EXTINF:3.000,
    segment9_0_av.ts
    #EXTINF:3.000,
    segment10_0_av.ts
    #EXT-X-ENDLIST
    

    and with this library we can generate a new VOD by truncating to the nearest possible length (depending on segment length). Eg. for a target length of 5, this will result in:

    #EXTM3U
    #EXT-X-TARGETDURATION:3
    #EXT-X-ALLOW-CACHE:YES
    #EXT-X-PLAYLIST-TYPE:VOD
    #EXT-X-VERSION:3
    #EXT-X-INDEPENDENT-SEGMENTS
    #EXT-X-MEDIA-SEQUENCE:1
    #EXTINF:3.000,
    segment1_0_av.ts
    #EXTINF:3.000,
    segment2_0_av.ts
    #EXT-X-ENDLIST
