Facebook is a funny creature.
If you post the link too quickly sometimes it doesn't pick up the embed. Once this happens once it'll cache that request so subsequent requests will no longer pick up the vid until the cache is cleared. To solve it use the short url (http://youtu.be/ijkDwqVUyQw) and leave it for a few seconds to load the preview. It caches by url only so changes in the url will let it try and cache again.
