Subject: [PATCH] drm/fourcc: Add formats R8, RG88, GR88
Date: Thu,  9 Jul 2015 01:38:42 -0700	[thread overview]
Message-ID: <1436431122-14489-1-git-send-email-chad.versace@intel.com> (raw)

The Kodi/XBMC 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.

I recently sent a patch series to mesa-dev that uses these new formats:
