How to add og:video tag at my site? I want to share my video site on Facebook.
Facebook detect only thumbnail of video.
I see France24.com add og:video on the source of site and show direct video on facebook.
I use auto_opengraph but this module can't generate og:video 
How  can i do?
new version of XML Sitemap module helped me.


  The XML sitemap module creates a sitemap that conforms to the
  sitemaps.org specification. This helps search engines to more
  intelligently crawl a website and keep their results up to date. The
  sitemap created by the module can be automatically submitted to Ask,
  Google, Bing (formerly Windows Live Search), and Yahoo! search
  engines. The module also comes with several submodules that can add
  sitemap links for content, menu items, taxonomy terms, and user
  profiles.
