Great news!
I have Intel processor and Nvidia GTX460M with proprietary drivers.
I have installed: libvdpau (for nvidia), CUDA, opencl-nvidia, libva
and libva-vdpau-driver. I have not installed in my system: libva-utils
and libva1. Arch linux has not dev version, only the items I've
listed. What I need to use to test: vaapi o vdpau? I think vdpau for
Results for playback of a h264 movie:

With CIN_HW_DEV=vaapi ./cin --> CPU 60%
with CIN_HW_DEV=vdpau ./cin --> CPU 11%
without vdpau or vaapi      --> CPU 60%.

With vdpau the whole system seems to me less reactive, but the
playback FPS are always at their max (as in the other cases).
I exit with CTRL+C voluntarily (I did not crash) to create a dump that I attach.
