Vimeo Froogaloop API, working in Fiddle but not WP
From: https://developer.vimeo.com/player/js-api#universal-event-spec If you’re embedding and controlling multiple players on a page or using our JS API library (Froogaloop), you should give each player a player_id that matches the id of the iframe element. http://player.vimeo.com/video/VIDEO_ID?api=1&player_id=vimeoplayer You may need to add the player_id query parameter to the src definition.
