Cannot get pixels when webcam is not running

I am trying to simply sync the current camera frame with the other person in the mutliplayer room, using photon. This is my script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

 public class streamWebcam : Photon.MonoBehaviour
 {
 
     public Texture2D imgCam;
     public Texture2D nocam;
     public Texture2D receivedImage = null;
 
     public void sendBytes()
     {
         WebCamTexture webcamTexture = new WebCamTexture();
 
         if (WebCamTexture.devices.Length > 0)
         {
             imgCam.SetPixels(webcamTexture.GetPixels()); //<--- ERROR HERE 
             imgCam.Apply();
             webcamTexture.Play();
         }
         else
         {
             imgCam = nocam;
             imgCam.Apply();
         }
 
         photonView.RPC("bytes", PhotonTargets.All, imgCam.EncodeToJPG(), PhotonNetwork.player.NickName);
     }
 
     [PunRPC]
     void bytes(byte[] received, string playername)
     {
         if (PhotonNetwork.player.NickName != playername)
         {
             print("received!");
             Texture2D got = new Texture2D(640, 480, TextureFormat.RGBA32, false, false);

             got.LoadImage(received);
             got.Apply();
             receivedImage = got;
         }
     }
 }

But i get this error when i try to do imgCam.SetPixels(webcamTexture.GetPixels());

Cannot get pixels when webcam is not running. I searched every where and didn't find anything regarding this. Please help.

Thanks, Mark.
