Another simple solution is to create a filter:
app.filter('trusted', ['$sce', function ($sce) {
return function(url) {
return $sce.trustAsResourceUrl(url);
};
}]);
Then specify the filter in ng-src
:
<video controls poster="img/poster.png">
<source ng-src="https://stackoverflow.com/questions/21292114/{{object.src" trusted}}" type="video/mp4"/>
