Hi,
For now, the best way I’ve found to embed youtube was commented here.
Have you tried to hide nav.bar? Something like this should work:
<ion-view title="..." hide-nav-bar="true">
<ion-content>
<div class="video-container">
<iframe src="http://www.youtube.com/embed/..." frameborder="0" allowfullscreen></iframe>
</div>
</ion-content>
</ion-view>
I leave this link that may be useful: YouTube Embedded Players and Player Parameters
