Hi Pekka,

I finally got everything working. I am using gbm_bo_create() and
gbm_bo_get_fd() to get a buffer that is filled by my grabber. Then I
use eglCreateImageKHR() and glEGLImageTargetTexture2DOES() to display
My only problem left is that glEGLImageTargetTexture2DOES() does only
accept ARGB8888 and not RGB888, which means I have to waste a lot of
PCIe bandwidth. Any ideas how to get around this? Or what would be a
more appropriate place to post this question?
