I'd like to track when the user clicks Play on a Youtube video in a Galleria slideshow, for tracking in Google Analytics.
As far as I can tell, Galleria creates an iframe with the src attribute set to your video URL, and not using the YouTube Iframe API, which allows you to listen to events.
So the only way I can think of doing it is implementing a plugin or modifying the Galleria video methods to use the Youtube Iframe API. Unless there's another way (or someone has already done this)?
