--- Comment #15 from Gwenole Beauchesne <gb.devel at gmail.com> ---
BTW, I had proposed an EXT_image_dma_buf_import_with_glformat extension that
would allow you to map each individual plane as a separate EGLImage akin to
what we do in Wayland, but requires you to write your own shader to perform YUV
to RGB conversion. Is that something that interests you and that I should
persue on pushing out?

Full support for GL_OES_EGL_image_external with planar YUV formats would
require much more work in Mesa, especially if you additionally want to support
fancy stuff like field selection, customization of the color matrix for
conversion (bt.601 vs. bt.709 vs XXX), etc.
