I know, i read this article already. My problem is that i have the youtube link in a customfield (not in the post_content).
So i cant use “Attach Video” because your script will not find the youtube-embeded code in the post.
That means, it is not possible (for me) to get an playable youtube video on facebook, right? If so, is there maybe a workaround? To change a little bit the code is not a problem for me.
