VADriverVTableEGL is deprecated in libva, we has a more efficient way to use vaapi and egl. You can refer to the examples in libyami-utils (https://github.com/01org/libyami-utils.git) for how to use vaapi and egl. > The DRM seems more complex, the reason I want to use the DRM is that, >GPU would not work with the 4K video rendering, so the DRM means that >directly output the video into video controller in our platform.

You should check libdrm and drm/i915.
