I have a single page website or a web application, how can I re-scan the DOM to find new media that was added after the initial page load for example via Ajax / XHR?

You can re-scan the entire document for new media like this:


If you have only updated parts of your web page, you can search for newly added videos and audio only in that area by passing a DOM element as a second parameter:

var updatedElement = document.getElementById('justUpdatedElement');
_paq.push(['MediaAnalytics::scanForMedia', updatedElement]);

As a developer I want to see more details about the logged data, is it possible?

Yes, you can enable the debug mode by calling the following method:


Calling this method will start logging all tracking requests and some more information to the developer console of your browser.

Is it possible to change the ping interval when a media is played?

Yes, it is possible by calling the method setPingInterval. By default, an update is sent every 5 seconds. Sending the ping more frequently can be useful to get a bit more accurate statistics, sending it less frequently can be useful to reduce the amount of traffic your server has to handle.

var intervalInSeconds = 2;
_paq.push(['MediaAnalytics::setPingInterval', intervalInSeconds]);

Make sure to call this method as early as possible, for example just after _paq.push(['setSiteId', 'X']);

How do I setup media analytics when using multiple Matomo (formerly Piwik) JavaScript trackers?

Matomo lets you track a website into different Matomo installations or into different Matomo websites. Learn more about using Multiple Matomo trackers on the JavaScript Tracking guide.

If you are using the regular _paq.push tracking method, everything will work out of the box when you create more trackers via _paq.push(['addTracker', url, idsite]);

Using _paq.push for multiple trackers is a good and simple way when you want to track the same data into different Matomo installations or into different Matomo websites.

// configuration of first tracker
_paq.push(['setTrackerUrl', '']);
_paq.push(['setSiteId', 1]);
// configuration of second tracker
_paq.push(['addTracker', '', 2]);

If you are working with Matomo tracker instances because you want to configure each tracker instance differently and track different data into each Matomo, you need to set the tracker instances manually:

window.matomoAsyncInit = function () {
    // This works from Matomo 2.17.1. Before 2.17.1 you need to define a method
    // `window.matomoMediaAnalyticsAsyncInit` instead of `window.matomoAsyncInit`.

    var matomoTracker1 = Matomo.getTracker('', 1);
    var matomoTracker2 = Matomo.getTracker('', 2);
    var matomoTracker3 = Matomo.getTracker('', 3);

    Matomo.MediaAnalytics.setMatomoTrackers([matomoTracker1, matomoTracker2, matomoTracker3]);

    // Media Analytics tracking is enabled by default, you can customize the tracking like this:

It is important to define these methods before the Matomo tracker file is loaded. Otherwise, your matomoAsyncInit or matomoMediaAnalyticsAsyncInit method will never be called.

Is it possible to not use the "paq.push" methods and instead call the MediaAnalytics tracker methods directly?

Yes. To initialize the Media tracker you need to define a callback method window.matomoMediaAnalyticsAsyncInit which will be executed as soon as the media tracker is initialized. As soon as this callback is called, you can be sure that the Matomo.MediaAnalytics object is defined.

In the matomo.js tracker we differentiate between two kind of methods:

  • Calling a tracker instance method affects only a specific tracker instance. In the docs you can identify a tracker method when the method name contains a single dot (.). For example MediaAnalytics.disableTrackEvents refers to a tracker method tracker that can be called like tracker.MediaAnalytics.disableTrackEvents().
  • Calling a static method affects all created tracker instances. In the docs you can identify a static method when the method name contains ::. For example MediaAnalytics::removePlayer refers to a static method Matomo.MediaAnalytics.removePlayer().
window.matomoMediaAnalyticsAsyncInit = function () {
    // static methods
    var intervalInSeconds = 2;

    // tracker methods
    var tracker = Matomo.getAsyncTracker(); 
    // get tracker instance if you do not have a reference to the tracker instance yet

Can I disable the tracking only on a specific tracker instance?

Yes. The static method disableMediaAnalytics disables the tracking for all of your created tracker instances. However, the tracker methods disableTrackEvents and disableTrackProgress can be used to disable the tracking only for a specific tracker instance like this:

window.matomoMediaAnalyticsAsyncInit = function () {
    // get tracker instance if you do not have a reference to the tracker instance yet
    var tracker = Matomo.getAsyncTracker(matomoSiteUrl, piwikSiteId); 

How do I define a media title in case the title cannot be detected automatically?

Matomo will automatically detect the title of a video or audio in most cases. In case you are using an old version of a media player, or an exotic media player which does not allow us to detect the title automatically, you can optionally define a callback method to detect the title of a video or audio manually based on your own custom logic.

For example if you always have only on video on a page, you could fallback to use the page title as video title:

_paq.push(['MediaAnalytics::setMediaTitleFallback', function (mediaElement) {
    return document.title;

In case you have multiple videos on a page, or you want to detect the title relative to the video or audio element, you can do this based on the mediaElement argument:

_paq.push(['MediaAnalytics::setMediaTitleFallback', function (mediaElement) {
    return $(mediaElement).parent().find('h2').text();
