Provided you are using the NextGEN Facebook Pro version (video detection modules are not included in the NextGEN Facebook Free version), videos from SlideShare, Vimeo, Wistia, and YouTube will be detected automatically from the following locations:

  1. A video entered in a theme or plugin custom field defined under the SSO > Advanced > Custom Meta > “Video Embed HTML Custom Field” or “Video URL Custom Field” options.
  2. A video entered in the custom Social and Search Optimization metabox “Video Embed HTML” or “Video URL” options.
  3. Embedded video HTML in your post / page content text or from a shortcode in your content text.

NextGEN Facebook does not consider simple URL links to videos to be an important / integral part of your content (like an embedded video). If you’d like NextGEN Facebook to consider video links as equal to embedded videos, you must use a custom NextGEN Facebook content filter like this one.
