    Concatenate videos for playback in a Video.js player

    Table of Contents

    Requirements

    Note that this plugin requires the master branch of VHS.

    Test Page

    To use the test page, clone VHS, run:

    npm install
    npm run build
    npm link

    Then in the plugin-concat directory, run:

    npm link @videojs/http-streaming

    Installation

    npm install --save @videojs/plugin-concat

    Usage

    To include videojs-concat on your website or web application, use any of the following methods.

    <script> Tag

    This is the simplest case. Get the script in whatever way you prefer and include the plugin after you include video.js, so that the videojs global is available.

    <script src="//path/to/video.min.js"></script>
    <script src="//path/to/videojs-plugin-concat.min.js"></script>
    <script>
      var player = videojs('my-video');
     
      player.concat(options);
    </script> 

    Browserify/CommonJS

    When using with Browserify, install videojs-concat via npm and require the plugin as you would any other module.

    var videojs = require('video.js');
     
    // The actual plugin function is exported by this module, but it is also
    // attached to the `Player.prototype`; so, there is no need to assign it
    // to a variable.
    require('@videojs/plugin-concat');
     
    var player = videojs('my-video');
     
    player.concat();

    RequireJS/AMD

    When using with RequireJS (or another AMD library), get the script in whatever way you prefer and require the plugin as you normally would:

    require(['video.js', '@videojs/plugin-concat'], function(videojs) {
      var player = videojs('my-video');
     
      player.concat(options);
    });

    Method

    videojs-concat uses the standard VHS manifest parsers (m3u8-parser and mpd-parser at the moment) to create manifest objects from the downloaded manifests, then merges the JSON objects. The result can be passed as JSON via a data URI to VHS.

    To use videojs-concat, all that needs to be done is to call the function videojs.concat.concatenateVideos and wait for the asynchronous operation to finish. The operation is asynchronous to allow for downloading of the manifests.

    Limitations

    • Renditions must have both audio and video (though demuxed is supported in addition to muxed).
    • Only HLS and DASH are supported (at the moment).
    • Only one rendition is used per source.
    • Alternate audio is not supported (except demuxed with default audio playlists).
    • WebVTT subtitle playlists are not supported.

    DRM

    DRM is supported via videojs-contrib-eme.

    To use DRM encrypted sources, add keySystems information to each encrypted manifest object in the same way as would be done for videojs-contrib-eme. See the README for details.

    Normally, licenses are requested for a video when segments are appended to the browser and the browser needs to decrypt the video. However, with multiple videos being concatenated, determining which key system information to use for the license request becomes challenging. Therefore, videojs-concat returns a function, initializeKeySystems(player) which sets up all of the key systems at once. initializeKeySystems(player) should be called after setting the source on the player. See [HLS Widevine and DASH Widevine] for an example.

    Examples

    Two of the same DASH source

    player.concat({
      manifests: [{
        url: 'https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd',
        mimeType: 'application/dash+xml'
      }, {
        url: 'https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd',
        mimeType: 'application/dash+xml'
      }],
      targetVerticalResolution: 720,
      callback: (err, result) => {
        if (err) {
          console.error(err);
          return;
        }
        console.log(result);
        player.src({
          src: `data:application/vnd.videojs.vhs+json,${JSON.stringify(result.manifestObject)}`,
          type: 'application/vnd.videojs.vhs+json'
        });
      }
    });

    Two of the same HLS source

      }],
      targetVerticalResolution: 720,
      callback: (err, result) => {
        if (err) {
          console.error(err);
          return;
        }
        console.log(result);
        player.src({
          src: `data:application/vnd.videojs.vhs+json,${JSON.stringify(result.manifestObject)}`,
          type: 'application/vnd.videojs.vhs+json'
        });
      }
    });

    Two of the same demuxed HLS source

        mimeType: 'application/x-mpegURL'
      }],
      targetVerticalResolution: 720,
      callback: (err, result) => {
        if (err) {
          console.error(err);
          return;
        }
        console.log(result);
        player.src({
          src: `data:application/vnd.videojs.vhs+json,${JSON.stringify(result.manifestObject)}`,
          type: 'application/vnd.videojs.vhs+json'
        });
      }
    });
