Missing OpenGL extension GL_EXT_framebuffer_blit on iMX6 Linux
Missing OpenGL extension GL_EXT_framebuffer_blit on iMX6 Linux
Hi.
We are using iMX6 SABRESD board with ltib-4.1.0. We need blit functionality for OpenGL framebuffer objects. It is present in OpenGL GL_EXT_framebuffer_blit extension, but is missing on iMX6.
We use QOpenGLFramebufferObject class from Qt. There is blitFramebuffer() method that was working fine on desktop and Android devices. Its method hasOpenGLFramebufferBlit() returns false on iMX6 which means extension is not present. As expected, blitFramebuffer() itself is not working (screen remains black).
We need this extension enabled. Why is it missing on iMX6 and is it possible to add it?
Regards,
Federico
