这仅仅是为我工作的解决方案：

This is the only solution that worked for me:

var app = angular.module('plunker', ['ngSanitize']);

app.controller('MainCtrl', function($scope, $sce) {
  $scope.trustSrc = function(src) {
    return $sce.trustAsResourceUrl(src);
  }

  $scope.movie = {src:"http://www.***.com/embed/Lx7ycjC8qjE", title:"Egghead.io AngularJS Binding"};
});

然后在iframe：

Then in an iframe:

<iframe class="***-player" type="text/html" width="640" height="385" ng-src="{{trustSrc(movie.src)}}" allowfullscreen frameborder="0">
