Yea, it's a while since I played with intel, but IIRC it only worked
for vo rather than decode, but then I didn't try very hard.

True, but, skylake can probably do hevc which is not so easy and the
OP has a laptop.
cherryview/braswell which I think are similar gen but low power can
do main level 6.2
Shame it's only 8 bit, looks like you'll need broxton (whatever that is)
to get 10bit -
I know there are vaapi patches for mplayer - it would be good if they
could be fixed. Since the thread on devel stopped I have retested (AMD)
several times in the hope that I could declare working, but no luck.
I'll retry again as time permits, because it seems a shame that they
apparently worked OK on intel.
Ignoring hw dec the post processing on recent intel chips is quite good
when I was testing a baytrail (10W TDP) it has a nice motion adaptive
de-interlace with edge interpolation which would be expensive for HD on CPU.
