With media tracking you can track the use of media streams (depends on your service package). The recorded functions are open, play, pause and stop (depending on the embedded medium), play duration, bandwidth, volume and mute setting.
Webtrekk offers you the possibility to track the use of media/videos on your website. Here is a guide to the implementation of the tracking.
You can find the latest documentation at this link: Media Tracking Plugin (v4.1.4).
There you can also download the documentation as a PDF file as well as the plugin.
