Hello, I was sucessfull using this https://github.com/nfl/jquery-oembed-all
Just add to Admin CP -> Appearance - > Custom HTML & CSS
then add to Custom Header
and enable it.
<script src="https://rawgit.com/nfl/jquery-oembed-all/master/jquery.oembed.js"></script>
<link rel="stylesheet" href="https://rawgit.com/nfl/jquery-oembed-all/master/jquery.oembed.css" />
<script>
$(function(){
$("div.topic-text a").oembed();
});
</script>
It doesn't embed all links, but if you use https you can have error by loading via http, i'm still seeing it. : )
edit. using this:
<script src="https://rawgit.com/kassius/jquery-oembed-all/master/jquery.oembed.js"></script>
<link rel="stylesheet" href="https://rawgit.com/kassius/jquery-oembed-all/master/jquery.oembed.css" />
<script>
$(document).ajaxComplete(function() {
$("div.topic-text a").oembed();
});
</script>
With this code I was able to embed wikipedia articles through https and also pdf through scribd. Very cool!!
