If you have ever tried to use an iframe, video or media element tag with a external site as source you have probably seen the Can't interpolate error. Heres two simple methods to get this working for you.

Method 1: Simple & Hackish

<iframe ng-src='{{ trustSrc(mainVideoUrl + video.filename) }}'>
</iframe>

Method 2: Proper Way

.config(function($sceDelegateProvider){
  $sceDelegateProvider.resourceUrlWhitelist([
    'self',
    "http://www.youtube.com/embed/**"
  ]);
})

Now you can use any url from youtube.com/embed/* or this domain.

<!-- Assuming mainVideoUrl == 'http://www.youtube.com/embed/'-->
<iframe ng-src='{{ mainVideoUrl + video.filename }}'>
</iframe>
