[needs-packaging] mesa
Please include "gallium_drv_video.so" which is a native va-api state tracker for mesa(gallium).

URL: http://mesa3d.sourceforge.net/
URL: http://freedesktop.org/wiki/Software/vaapi/ #intel/vdpau
License: http://www.mesa3d.org/license.html

Notes:
Currently (as of today) in ubuntu 15.10 nightly amd64, va-api(vaapi) on AMD/Ati radeon opensource display hardware is using a vdpau backend  0.7.4 by Splitted-Desktop Systems (wrapper) on gallium r600. Although its possible and probably preferred (better performance less copying) to use a native implementation which mesa(gallium) 10.4 and higher delivers in a form of a va-api state tracker.

The preferred setup needs that "gallium_drv_video.so" binary which is
currently unavailable in ubuntu and debian. As an example I added a
package/binary from archlinux. Copying the gallium_drv_video.so to
/usr/lib/x86_64-linux-gnu/dri/ and symlinking(correcting) the
libLLVM-3.6.so to arch-linux default /usr/lib/ location and exporting a
variable was enough to make it work!

#example by archlinux

export LIBVA_DRIVER_NAME=gallium
vainfo #preferred setup using gallium va-api from arch-linux (symlinked libLLVM-3.6.so to /usr/lib)

      VAProfileH264High               :	VAEntrypointVLD

I guess this binary "gallium_drv_video.so" might be available as a
compile flag in the current mesa implementation... intel and vdpau has
their own current implementation in a separate libva branch
