If you are talking about this api:http://cgit.freedesktop.org/vaapi/libva/tree/va/egl/va_egl.h,
Then yes, it is not implemented in driver.

But there are other ways to map deocoded va sufaces to eglimage through dmabuf and vaAcquireBufferHandle.

A detailed implementation with comments here: https://github.com/01org/gstreamer-vaapi/blob/master/gst-libs/gst/vaapi/gstvaapisurface_egl.c

Anther implementation for the same here: https://github.com/01org/libyami/blob/master/egl/egl_vaapi_image.cpp
