How often is the current progress of a media updated when a visitor is playing it?
By default, the user watching a video or listening to an audio will be tracked every 5 seconds and whenever the player is interacted with by the user (such as when clicking pause, resume or fullscreen). To change the tracking interval, you can call the following tracking method:
// sends an update every 2 seconds to get more accurate results (this causes more server load)
var intervalInSeconds = 2;
_paq.push(['MediaAnalytics::setPingInterval', intervalInSeconds]);
