Current Position (parameter: pos)

The pos action records which parts of a media file have been viewed. It is also used to track the last position in case the user closes the browser or app window.

This action always works with two parameters:

  • mt1 – current play position (in seconds)

  • mt2 – total length of the media file (in seconds)

When to send

  • Default interval: every 30 seconds while the media is in play mode.

  • Do not send pos events when the media is paused or stopped. In these cases, the timer must also be paused.

  • For live streams (no total length mt2 available), the interval is fixed at 60 seconds.

Rules & Pitfalls

  • The allowed interval depends on the total length of the media file (mt2).

  • The media pixel divides the total length by 60 to calculate the minimum interval.

  • The interval can never be shorter than 10 seconds.

  • After each pos event, the timer restarts.

  • If you send events more frequently than allowed, additional requests are ignored.

Formula: 

Interval = max(10, mt2 / 60)

Examples:

  • mt2 = 600s (10 min) → 600/60 = 10s

  • mt2 = 1200s (20 min) → 1200/60 = 20s

If the calculated interval is 30 seconds but you send every 20 seconds, only every second request is accepted. This means the event is effectively measured after 40 seconds.
