Follow-up of kernel patch: https://lists.freedesktop.org/archives/dri-devel/2015-July/086041.html
The Kodi/XBMC and ChromeOS developers want to transcode NV12 to RGB with OpenGL shaders, importing the two source planes through EGL_EXT_image_dma_buf_import. That requires importing the Y plane as an R8 EGLImage and the UV plane as either an RG88 or GR88 EGLImage.
