[Libva] egl and vaapi

[Michael Henson]

My apologies if this is well known information ... I have not been able to
find an answer in my searching.
I am using libva to decode JPEG. I want to then use decoded surface as a gl
texture. This works fine if I use copySurfaceGLX(). However it seems that
the copy surface is slow (450MB/s) on Intel i7 ivy bridge 4770. Possibly
because it is waiting for sync ... Not sure. I am assuming that it is
possible to use the decoded result directly by associating it with a
texture target. To this end I tried to implement with EGL. However va_egl.h
no longer contains any of the surface management functions that it used to.
Without transitioning to wayland, I am uncertain what to do.
Can someone please point me in the right direction.
Thanks,
Michael.
