timeout in AngularJS

To do what you want, whenever the application starts you redirect the route to any screen, to do this, do a state go in the run:

angular.module('myApp', [])
  .config(something => {})
  .run(function ($state) {
    $state.go('rotaDaTelaComVideo');
  });

According to Angular documentation: Documentation

In this way, it is safe to call a route in the run, at the same time that in the next iteration of the Angular it will load its module.

Bonus :

Still, if you want the video to run only once, you can save a flag in the localStorage:

angular.module('myApp', [])
  .config(something => {})
  .run(function ($state, $window) {
    if ($window.localStorage['alreadyShown'] !== true) {
      $state.go('rotaDaTelaComVideo');
      $window.localStorage['alreadyShown'] = true;
    }
  });

So it will only run the first time the user starts the application, or after clearing all data from the cache.

Inject $state to your Controller and after the video ends use $state.go .

function goLogin(){
$state.go("app.login-new");
}

<ion-view title="splash" id="splash" hide-nav-bar="true">
    <ion-content padding="true" class="has-header vcenter" scroll="false">
<video preload="metadata" autoplay="autoplay" webkit-playsinline="webkit-playsinline" class="videoPlayer">
  <source src="video/splash.mp4" type="video/mp4"/>
</video>
    </ion-content>
</ion-view>

Controller

.controller('splash', ['$scope', '$stateParams', 
function ($scope, $stateParams) {


}])
