Hi All,

I'm having a 1k*1k*rgb texture that is rendered using shader and I want to copy the pixels to buffer so that I use Opencv with it. I tried glreadpixels and its very slow, I tried Pixbuffer of Egl, it has the same perforamance its very slow 7FPS. I'm using Mali400 on Exynos4412

Here is the code
  Please view it in pastebin, there is a problem with code posting here

    Hi Ahmed,

    Just checking I understand, it sounds like you are rendering something using the GPU, and them attempting to perform some CV on it. This sounds like a fairly unusual usecase, can you give us some more detail on what it is that you're trying to achieve, so we can better advise?

    Thanks,
    Chris
