There is no libvdapu_965.so.

It's part of the x11 overlay in layman
layman --add x11
Let's clear this up: vdpau and vaapi are two APIs for hardware video
acceleration. The package x11-libs/libvdpau-va-gl implements the VDPAU api
using VAAPI+OPENGL library calls, the package x11-libs/libva-vdpau-driver
implements the VAAPI api using VDPAU library calls. So these two are
effectively opposites. I was once wondering if it would be possible to
bring these two to recurse...
But let's get back on topic: VAAPI is pretty much only implemented on
intel cards, and only on newer ones supported by the i965 driver. So you
will definitely need VIDEO_CARDS="i965 intel" set.
Next you need to install x11-libs/libva which will also pull in
x11-libs/libva-intel-driver. Check with vainfo that this works.
After that you can install x11-libs/libvdpau-va-gl and x11-misc/vdpauinfo.
You also need to have the environment variable VDPAU_DRIVER=va_gl set
somewhere. Drop this in /etc/profile.d/vdpau.sh:
export VDPAU_DRIVER=va_gl
Do the usual env-update && source /etc/profile, and then check with
vdpauinfo that everything works.
Now you can build all the packages you need with the vdpau USE flag.
