Question Convert Render Texture to OpenGL TEXTURE 2D

Hi everyone ! I'm new with OpenGL,

I need to convert a RenderTexture from my main Camera to an OpenGL TEXTURE_2D to send it using Spout in a UWP project.


here is what i tried, but getting error (cannot convert System.IntPtr to uint) :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Spout.Interop;
5. using System;
6. using OpenGL;
7.  
8. public class SpoutSend : MonoBehaviour
9. {
10.     //SpoutSender sender;
11.     public RenderTexture texture;
12.     DeviceContext deviceContext;
13.     SpoutSender sender;
14.  
15.     // Start is called before the first frame update
16.     void Start()
17.     {
18.         deviceContext = DeviceContext.Create();
19.         IntPtr glContext = IntPtr.Zero;
20.         glContext = deviceContext.CreateContext(IntPtr.Zero);
21.         deviceContext.MakeCurrent(glContext); // Make this become the primary context
22.         sender = new Spout.Interop.SpoutSender();
23.         sender.CreateSender("CsSender", 1920, 1080, 0); // Create the sender
24.     }
25.  
26.     // Update is called once per frame
27.     void Update()
28.     {
29.         var Texturepointer = toTexture2D(texture).GetNativeTexturePtr();
30.         sender.SendTexture(Texturepointer, Gl.TEXTURE_2D, 1920, 1080, false, 0);
31.     }
32.  
33.     public Texture2D toTexture2D(RenderTexture rTex)
34.     {
35.         Texture2D dest = new Texture2D(rTex.width, rTex.height, TextureFormat.RGBA32, false);
36.         dest.Apply(false);
37.         Graphics.CopyTexture(rTex, dest);
38.         return dest;
39.     }
40. }
