Render Texture garbage collection

Hi,

I'm sending the views from two cameras over a TCP connection. The cameras render to render textures, and I convert them to byte[] and send them:

Code (CSharp):

1.    
2. IEnumerator SendTexture()
3.     {
4.         Debug.Log(gameObject.name + " In SendTexture(), sendingVideo = " + sendingVideo);
5.        
6.         readyToGetFrame = true;
7.  
8.         while (sendingVideo)
9.         {
10.             yield return new WaitForSeconds(1/fps);
11.             //Wait for End of frame - Render Textures shouldn't be called before that
12.             yield return waitEndOfFrame;
13.  
14.             // Get the images from the cameras to the textures
15.             RenderTexture.active = depthRenderTexture;
16.             depthTexture.ReadPixels(textureRect, 0, 0);
17.  
18.             RenderTexture.active = colorRenderTexture;
19.             colorTexture.ReadPixels(textureRect, 0, 0);
20.  
21.             // Convert the textures to byte[]
22.             colorBytes = colorTexture.GetRawTextureData();
23.             depthBytes = depthTexture.GetRawTextureData();
24.  
25.  
26.             readyToGetFrame = false;
27.  
28.             // Convert a 4 bytes per pixel array to one bytes per pixel
29.             singleChannelDepthBytes = Utils.GetSingleChannelDepth(depthBytes);
30.  
31.             // Actually sending the textures
32.                 Loom.RunAsync(() =>
33.                 {
34.                     timestamp = Utils.ToUnixTime(DateTime.UtcNow).ToString();
35.                     timeStampBytes = Encoding.ASCII.GetBytes(timestamp);
36.                     stream.Write(timeStampBytes, 0, timeStampBytes.Length);
37.                    
38.                     //Send the color image bytes
39.                     stream.Write(colorBytes, 0, colorBytes.Length);
40.  
41.                     //Send the depth image bytes
42.                     stream.Write(singleChannelDepthBytes, 0, singleChannelDepthBytes.Length);
43.  
44.                     //Sent. Set readyToGetFrame true
45.                     readyToGetFrame = true;
46.                 });
47.             //Wait until we are ready to get new frame (Until we are done sending data)
48.             while (!readyToGetFrame)
49.             {
50.                 yield return null;
51.             }
52.         }
53.     }
54.  

The problem is that Garbage Collection allocates 5.6 MB each time this happens:



Any advice?

Thanks
