Fill angularjs scope with a dynamic array

My Angular App works with

  <script>
    var app = angular.module('MyApp', []);
    app.controller('myCtrl', function ($scope, $sce) {

          $scope.urls = [
            {
              "url": $sce.trustAsResourceUrl("https://www.youtube.com/watch?v=KhzGSHNhnbI")
            },
            {
              "url": $sce.trustAsResourceUrl("https://www.youtube.com/watch?v=OPxeCiy0RdY")
            }
          ]

    });
  </script>

But it doesn't work with

  <script>
      urls = [
            {
              "url":"https://www.youtube.com/watch?v=KhzGSHNhnbI" 
            },
            {
              "url":"https://www.youtube.com/watch?v=OPxeCiy0RdY"          
            }
          ]
  </script>   

  <script>
    var app = angular.module('MyApp', []);
    app.controller('myCtrl', function ($scope, $sce) {

      function myUrl(url) {
          this.url = url;
      }

      $scope = [];
      urls.forEach(function (url, i) {

          $scope.push(new myUrl($sce.trustAsResourceUrl(url)));

      });

    });
  </script>

Update: still doesn't work

 <script>
    var app = angular.module('MyApp', []);
    app.controller('myCtrl', function ($scope, $sce) {

        function myUrl(url) {
            this.url = url;
        }

        $scope.urls = [];
        urls.forEach(function (url, i) {

            $scope.urls.push(new myUrl($sce.trustAsResourceUrl(url)));

        });

    });
  </script>

Error: [$sce:itype] http://errors.angularjs.org/1.4.3/$sce/itype?p0=resourceUrl

Solution

replace $scope.push(new myUrl($sce.trustAsResourceUrl(url))); with $scope.push(new myUrl($sce.trustAsResourceUrl(url.url)));

 urls = [
            {
              "url":"https://www.youtube.com/watch?v=KhzGSHNhnbI" 
            },
            {
              "url":"https://www.youtube.com/watch?v=OPxeCiy0RdY"          
            }
          ]


var app = angular.module('plunker', []);
    app.controller('MainCtrl', function ($scope, $sce) {

      function myUrl(url) {
          this.url = url;
      }

      $scope.urls = [];
      urls.forEach(function (url, i) {

          $scope.urls.push(new myUrl($sce.trustAsResourceUrl(url.url)));

      });

    });
