VideoPlayer with Image Target

Hey, I have a VideoPlayer that is playing a video from an online link. I am trying to make the application so that when a specific image is tracked a video will start to play. Currently I am trying to play a video that is already prepared and paused in the Start() function. I have changed the code many times and nothing is working. can someone tell me what is wrong with the code please?

using UnityEngine; using UnityEngine.Video;

            GameObject camera = GameObject.Find("ARCamera/Camera");             vPlayer = camera.AddComponent<VideoPlayer>();             vPlayer.url = "http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4";             vPlayer.renderMode = UnityEngine.Video.VideoRenderMode.CameraNearPlane;             vPlayer.playOnAwake = false;             //vPlayer.targetCameraAlpha = 0.5f;             //vPlayer.prepareCompleted += Prepared;             vPlayer.Pause();                         Debug.Log("prep reached!");                     }

        void Playvid()         {             vPlayer.Play();             Debug.Log("playing vid!");         }
