Monitor Shaka player

1Install shakaplayer-mux

Include the Mux JavaScript SDK on every page of your web app that includes video.

copy
<script src="https://src.litix.io/shakaplayer/5/shakaplayer-mux.js"></script> 

2Initialize Mux Data

Get your ENV_KEY from the Mux environments dashboard.

Call new shaka.Player like you normally would and get the return value (a reference to the player). Call initShakaPlayerMux with the player reference and the SDK options.

copy
<div id="my-player"></div>
<script>
  const playerInitTime = Date.now();
  const video = document.querySelector('#my-player');
  const player = new shaka.Player(video);

  // calling initShakaPlayerMux will return a shakaPlayerMux object
  // you will need this for handling any errors when calling
  // player.load()
  const shakaPlayerMux = initShakaPlayerMux(player, {
    debug: false,
    data: {
      env_key: 'ENV_KEY',
      // Metadata
      player_name: 'Custom Player', // ex: 'My Main Player',
      player_init_time: playerInitTime // ex: 1451606400000
      // ... and other metadata
    }
  });

  player.load('https://stream.mux.com/yb2L3z3Z4IKQH02HYkf9xPToVYkOC85WA.m3u8').then(function () {
    // Successfully loaded the manifest. Mux data will begin tracking
  }).catch(function (error) {
    // There was an error loading this manifest. Call shakaPlayerMux.loadErrorHandler(error) so that Mux data can track this error.
    shakaPlayerMux.loadErrorHandler(error);
    // Do the rest of your error handling logic
  })

  // When you are ready to destroy shakaplayer, you must also destroy
  // the mux monitor
  player.destroy()
  player.mux.destroy()
</script> 

3Make your data actionable

The only required field in the options that you pass into shakaplayer-mux is env_key. But without some metadata the metrics in your dashboard will lack the necessary information to take meaningful actions. Metadata allows you to search and filter on important fields in order to diagnose issues and optimize the playback experience for your end users.

Pass in metadata under the data on initialization.

copy
initShakaPlayerMux(player, {
  debug: false,
  data: {
    env_key: 'ENV_KEY',
    // Site Metadata
    viewer_user_id: '', // ex: '12345'
    experiment_name: '', // ex: 'player_test_A'
    sub_property_id: '', // ex: 'cus-1'
    // Player Metadata
    player_name: '', // ex: 'My Main Player'
    player_version: '', // ex: '1.0.0'
    player_init_time: '', // ex: 1451606400000
    // Video Metadata
    video_id: '', // ex: 'abcd123'
    video_title: '', // ex: 'My Great Video'
    video_series: '', // ex: 'Weekly Great Videos'
    video_duration: '', // in milliseconds, ex: 120000
    video_stream_type: '', // 'live' or 'on-demand'
    video_cdn: '' // ex: 'Fastly', 'Akamai'
  }
});

4Changing the video

There are two cases where the underlying tracking of the video view need to be reset:

1. New source: When you load a new source URL into an existing player.
2. New program: When the program within a singular stream changes (such as a program change within a continuous live stream).

Note: You do not need to change the video info when changing to a different source of the same video content (e.g. different resolution or video format).

New source

If your application plays multiple videos back-to-back in the same video player, you need to signal when a new video starts to the Mux SDK. Examples of when this is needed are:

• The player advances to the next video in a playlist
• The user selects a different video to play

See metadata in Make your data actionable for the full list of video details you can provide. You can include any metadata when changing the video but you should only need to update the values that start with video_.

It's best to change the video info immediately after telling the player which new source to play.

copy
// player is the instance returned by `new shaka.Player`
player.mux.emit('videochange', {
  video_id: 'abc345',
  video_title: 'My Other Great Video',
  video_series: 'Weekly Great Videos',
  // ...
}); 

New Program

In some cases, you may have the program change within a stream, and you may want to track each program as a view on its own. An example of this is a live stream that streams multiple programs back to back, with no interruptions.

In this case, you emit a programchange event, including the updated metadata for the new program within the continuous stream. This will remove all previous video data and reset all metrics for the video view, creating a new video view. See Metadata for the list of video details you can provide. You can include any metadata when changing the video but you should only need to update the values that start with video.

Note: The programchange event is intended to be used only while the player is currently not paused. If you emit this event while the player is paused, the resulting view will not track video startup time correctly, and may also have incorrect watch time. Do not emit this event while the player is paused.

copy
// player is the instance returned by `new shaka.Player`
player.mux.emit('programchange', {
  video_id: 'abc345',
  video_title: 'My Other Great Video',
  video_series: 'Weekly Great Videos',
  // ...
}); 

5Advanced options

Disable cookies

By default, Mux plugins for HTML5-based players use a cookie to track playback across subsequent page views. This cookie includes information about the tracking of the viewer, such as an anonymized viewer ID that Mux generates for each user. None of this information is personally-identifiable, but you can disable the use of this cookie if desired. For instance, if your site or application is targeted towards children under 13, you should disable the use of cookies.

This is done by setting disableCookies: true in the options passed to the Mux plugin.

copy
// player is the instance returned by `new shaka.Player`
initShakaPlayerMux(player, {
  debug: false,
  disableCookies: true,
  data: {
    env_key: "ENV_KEY",
    // ...
}); 

Over-ride 'do not track' behavior

By default, shakaplayer-mux does not respect Do Not Track when set within browsers. This can be enabled in the options passed to Mux, via a setting named respectDoNotTrack. The default for this is false. If you would like to change this behavior, pass respectDoNotTrack: true.

copy
// player is the instance returned by `new shaka.Player`
initShakaPlayerMux(player, {
  debug: false,
  respectDoNotTrack: true,
  data: {
    env_key: "ENV_KEY",
    // ...
}); 

Customize error tracking behavior

By default, shakaplayer-mux will track errors emitted from the video element as fatal errors. If a fatal error happens outside of the context of the player, you can emit a custom error to the mux monitor.

copy
// player is the instance returned by `new shaka.Player`
player.mux.emit('error', {
  player_error_code: 100,
  player_error_message: 'Description of error'
}); 

When triggering an error event, it is important to provide values for player_error_code and player_error_message. The player_error_message should provide a detailed description of the error as it happened. The player_error_code must be an integer, and should provide a category of the error. If the errors match up with the HTML Media Element Error, you can use the same codes as the corresponding HTML errors. However, for custom errors, you should choose a number greater than or equal to 100.

In general you should not send a distinct code for each possible error message, but rather group similar errors under the same code. For instance, if your library has two different conditions for network errors, both should have the same player_error_code but different messages

Error translator

If your player emits error events that are not fatal to playback or the errors are unclear and/or do not have helpful information in the default error message and codes you might find it helpful to use an error translator or disable automatic error tracking all together.

copy
function errorTranslator (error) {
  return {
    player_error_code: translateCode(error.player_error_code),
    player_error_message: translateMessage(error.player_error_message),
  };
}

// player is the instance returned by `new shaka.Player`
initShakaPlayerMux(player, {
  debug: false,
  errorTranslator,
  data: {
    env_key: "ENV_KEY",
    // ...
  }
}); 

If you return false from your errorTranslator function then the error will not be tracked. Do this for non-fatal errors that you want to ignore. If your errorTranslator function itself raises an error, then it will be silenced and the player's original error will be used.

Disable automatic error tracking

In the case that you want full control over what errors are counted as fatal or not, you may want to consider turning off Mux's automatic error tracking completely. This can be done by passing automaticErrorTracking: false in the configuration object.

copy
// player is the instance returned by `new shaka.Player`
initShakaPlayerMux(player, {
  debug: false,
  automaticErrorTracking: false,
  data: {
    env_key: "ENV_KEY",
    // ...
  }
}); 

Track Ad playback with a custom integration

Our integration for Shaka player does not have a built-in integration for tracking ad playback. If you would like to track ads played within Shaka player, you will need to build a custom integration, which is detailed here: Build a Custom Integration.
