Actually, I think this version will do encode vaapi device selection
too, like this:
CIN_DRM_DEC=/dev/dri/renderD129 CIN_DRM_ENC=/dev/dri/renderD128 bin/cin
but for some reason decode via Radeon device (on pcie bus?) and encode
on integrated GPU via i965 driver much slower!
I used intel_gpu_top and radeontop (1.4 git from github) for checking
each video block load.

hm, so it also works slow with just Intel device. But may be this is
because I run whole thing with remote display via ssh!
