Fix Unity Project IOS Issues

Fix some issues in an already built app. We provide the files. The project was created using Unity 3D, Vuforia and XCode. We require the issue to be solved altering the project as little as possible. The project consists on an Unity app that when a marker is detected an animation of a 3D Asset starts followed by the reproduction of a video. The video pauses when the marker is lost and plays again from where it was left when the marker is found again. The issues are two: 1) the 3D asset shakes every now and then randomly 2) When we run the app on iPhone the sound of the video plays but the video doesn't show, problem we don't have when we run it on Android. Solutions we expect: 1) Nothing shakes when we run the app. 2) The animation of the 3D asset starts playing when the marker is detected and when that ends the video starts playing. The video pauses when the marker is lost and plays from where it was left when the marker is found again. Deliveries: Unity project, XCode Project.
