Angular youtube-embed error when passing a variable in ng repeat
<p>I have installed this <a href="https://github.com/brandly/angular-youtube-embed" rel="nofollow">youtube-embed package</a> in order to do manipulate elements on my page on player events. In my app I am listing articles with <code>ng-repeat</code> so I need to pass the video url as a variable to the directive. Since on the package github page it is described that you should pass a <code>$scope variable</code> name as a string to the directive in order to display a video, since I can't pass it as a scope variable, I wonder if I can pass it in ng-repeat?
Because when I do it like this I get an error:</p>

<pre><code>&lt;youtube-video video-url="{{article.external_media[0].original_url}}"&gt;&lt;/youtube-video&gt;
</code></pre>

<blockquote>
