Unity, How To SetPixels32 Properly? - unity3d

Question

I'm receiving the error SetPixels32 called with invalid number of pixels in the array UnityEngine.Texture2D:SetPixels32(Color32[]) on a line of code that is trying to retrieve a pixel array.
In some instances I receive the error but in others the webcams stream just fine. I'm not sure why this is occurring. This is the line of code that is giving me problems:
streamTexture.SetPixels32(webcamTexture.GetPixels32(pixels))
That isn't much to go on, however, below is the full script. If Anyone can tell me why this error is occurring since the streaming texture is set to the dimensions of the webcam texture. Any help is much appreciated!
using System.Collections;
using UnityEngine;
using Photon.Pun;
using UnityEngine.UI;
public class WebcamStream : MonoBehaviourPun, IPunObservable
{
[SerializeField] private LocalPlayerSettings playerSettings;
[SerializeField] private AvatarHandler parent;
[SerializeField] private RawImage streamRawimage;
private WebCamTexture webcamTexture;
private Texture2D streamTexture;
private Color32[] pixels;
private byte[] data;
private void OnEnable()
{
if (!parent.photonView.IsMine)
return;
InitWebcam();
}
private void OnDisable()
{
if (!parent.photonView.IsMine)
return;
webcamTexture.Stop();
}
private void InitWebcam()
{
//cast dimensions of target UI as ints for new webcam texture
int width = (int)streamRawimage.rectTransform.rect.width;
int height = (int)streamRawimage.rectTransform.rect.height;
//set new dimensions and target device
webcamTexture = new WebCamTexture(width, height)
{
deviceName = playerSettings.Webcam
};
//display webcam texture on the raw image and start camera
streamRawimage.material.mainTexture = webcamTexture;
webcamTexture.Play();
//set pixels and stream texture to match webcamTexture
pixels = new Color32[webcamTexture.width * webcamTexture.height];
streamTexture = new Texture2D(webcamTexture.width, webcamTexture.height, TextureFormat.RGB24, false);
//Begin Streaming Webcam Data
StartCoroutine(StreamWebcam());
}
private IEnumerator StreamWebcam()
{
while (webcamTexture.deviceName == playerSettings.Webcam)
{
if (webcamTexture.isPlaying)
{
//set the target texture pixels to the webcam texture pixels and apply get/set
streamTexture.SetPixels32(webcamTexture.GetPixels32(pixels));
streamTexture.Apply();
//convert image to byte array
data = streamTexture.EncodeToJPG();
}
yield return null;
}
webcamTexture.Stop();
if(WebCamTexture.devices.Length > 0)
{
InitWebcam();
}
}
public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
{
if (stream.IsWriting)
{
//send the byte array through the stream
stream.SendNext(data);
}
else
{
//convert object received into byte array via cast
data = (byte[])stream.ReceiveNext();
//create new texture to load received data into
streamTexture = new Texture2D(1, 1, TextureFormat.RGB24, false);
streamTexture.LoadImage(data);
//set webcam raw image texture to the newly updated texture
streamRawimage.texture = streamTexture;
}
}
}

Solved! There was another script responsible for enabling this scripts game object and needed a yield for about 1 second.
Also a quick edit of streamRawimage.material.mainTexture = webcamTexture; to streamRawimage.texture = webcamTexture; fixed another issue surrounding a missing texture.
