Transformer rules not working

I’ve been struggling with the plugin since its Github days. Sorry about that.

But here’s where I’m stuck now. Got the plugin running, got my URL verified, feed link is working, set it up as dev RSS, it’s working, can see the articles on mobile app.

But there is one major issue: almost all my articles have featured videos and the theme places it. (I just have to put the video URL, say YouTube, Vimeo etc into a meta box while composing). This doesn’t appear on the instant articles. And I understand that it’s a transformation problem.

I’ve tried multiple variations of Transformer Rules, but nothing seem to work. Can someone please help this poor soul. 🙁

My HTML code looks like this:

<div class="video_outer">
     <iframe id="my_youtube_player" width="600" height="560" src="http://www.youtube.com/embed/1y4UroIP4kM?enablejsapi=1&feature=oembed&wmode=opaque&showinfo=0&showsearch=0&rel=0&start=5" frameborder="0" allowfullscreen=""></iframe>
</div>

Another minor problem:
Once I give Facebook app access, and click on the Login with Facebook button, it loads the same page again. I’ve given it access so nothing happens now. Same button reappears. No list of pages I manage. How to solve this issue?

Please help.
