The plugin will also provide you with dedicated elements to embed media elements from a variety of sources. Currently, self-hosted HTML5 audio and video files, and videos from YouTube, DailyMotion and Vimeo are supported. All videos can either be directly inserted via iFrame or with a preview image (or a variety of other triggers) to be opened in a lightbox.
