Switching clip for videoPlayer in Unity 5.6.0f3 causes Lag and makes CPU usage 100%

Making project with SteamVR and unity 5.6.0f3. making a simple switching video mechanism and everytime the videoclip switches within the videoplayer and it plays the new clip. it causes a CPU usage spike which shows that the problem is with VideoPlayer.set_clip()


and my steamVR switches from the application to the compositor screen for a split second.
My settings for the videoplayer is

I have also tried stopping the clip before switching and playing again.
This is my code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Video;
[RequireComponent(typeof(AudioSource))]
public class PlayVideo : MonoBehaviour
{
    
     public VideoClip clip;
     private SerialUISummoner canvas;
     VideoPlayer video;
     int vsyncprevious;
     private bool playing = false;
     // Use this for initialization
     void Start()
     {
         video = GetComponent<VideoPlayer>();
         video.clip = clip;
         video.SetTargetAudioSource(0, GetComponent<AudioSource>());
         canvas = Object.FindObjectOfType<SerialUISummoner>();
     }
     // Update is called once per frame
     void Update()
     {
         if (canvas != null)
         {
             if (canvas.Showing && !playing)
             {
                 playing = true;
                 print("START");
                 PlayVid();
             }
             if (!canvas.Showing && playing)
             {
                 playing = false;
                 StopVid();
             }
         }
     }
     public void PlayVid()
     {
         video.Play();
     }
     public void StopVid()
     {
         video.Stop();
     }
     public void Change()
     {
         if (video != null)
         {
             playing = false;
             video.clip = clip;
                 playing = true;
                 PlayVid();
         }
     }
