I am facing the following issue on IMX6Q(Android 4.3JB):
EGLimage of a GraphicBuffer memory is attached to an OpenGL texture and the texture is attached to an OpenGL FrameBufferObject as a Color Attachment. Render to texture is being used for off-screen rendering.
This approach is being used in order to avoid glreadpixels.
I find that upon using glreadpixels, the rendered frame is being obtained. But, the provided GraphicBuffers are not getting updated at all.
I always get a black image upon dumping the contents of the GraphicBuffers to a file.
I have attached the test code. I am trying to display an image on screen using openGL in the test code.
Any help on this issue would be very valuable.
