oEmbed is an open format for allowing representation of a URL on third party sites. If a media source provides an oEmbed option, you can fetch rich information about a requested resource and render in-depth HTML with it.<br />
<br />
Note: when enabling oEmbed, any HTML entered in the 'Embed template' field is ignored, as are call-backs defined in 'Embed HTML callback'. Additionally, XenForo handles only JSON responses from oEmbed sources.<br />
