With fitvids.js Library, Video is Shown but There is No Way to Control by
Code

I'm using fitvids.js and my HTML is this:
<div class="fitvids">
<iframe src="video/myVideo.mp4" width="500" height="281"
allowfullscreen></iframe>
</div>
The video is shown as it should, but the problem is that I can not control
my video (pause, play, ...) through jQuery/JavaScript using my custom
"Pause Me" button. When I "alert" the content of the iframe tag through:
alert($("iframe").html());
, I see an empty message. There is no sign of the video tag in the alert
and I know that without video tag I cannot pause/play my video through
code.
I hope I have provided enough info for you guys to help me out break this
lock.
