Increasing memory usage when using target texture and saving the image

Hi,

The code below is run many times during every mainCamera's Update(). storeCamera is not the same as mainCamera and has no script component. The problem is that Unity's memory consumption becomes absurdly high after running this (going from 2GB to 11GB in 15sec). Is this issue related to Unity or the code?

Code (CSharp):

1.  
2. void Store(){
3. ...
4. storeCamera.Render();
5. ...
6. RenderTexture.active = storeCamera.targetTexture;
7. Texture2D r = new Texture2D(storeCamera.targetTexture.width, storeCamera.targetTexture.height);
8. r.ReadPixels(new Rect(0, 0, storeCamera.targetTexture.width, storeCamera.targetTexture.height), 0, 0);
9. r.Apply();
10. byte[] bytes = r.EncodeToJPG(75);
11. File.WriteAllBytes(framePath + frameIndex + ".jpg", bytes);
12. frameIndex++;    
13. }

 

When you make a Texture2D() yourself you have to Destroy() it when you're done, otherwise it will continue to occupy memory.

 

Thank you.
