WordPress.org

Callisto.fm's WordPress plugin works by including a javascript library that checks each page's HTML for video and audio players and then listens for user events like "play", "pause", "finish", and "fullscreen". These events are sent to Callisto's API where they are recorded for later analysis. You can then login to Callisto.fm and see realtime and historical charts that allow you to better understand how your visitors are engaging with your media.
