Thank you for testing!

On my Intel Corporation 3rd Gen Core processor Graphics 
Controller, the results were even more exciting: from ~35% to ~7% 
CPU load while playing a 720p H.264 film.  That's a factor of 5.

Sadly, my hardware's too old to accelerate H.265 (HEVC) stream 
(they play just fine on the CPU), but even so: a significant 
majority of my media collection just got significantly 
accelerated…  for free!  \o/

I love this business,

T G-R
