Is this new on IVB, or should it also work on SNB?
The PRM available at <http://www.intellinuxgraphics.org/> for Ivy
Bridge mentions that the HW decoding engine supports H.264 high
profile up to level 5.1. For Sandy Bridge, the /vaapi.html page on the
same website mentions that it only supports H.264 high profile up to
level 4.1. Based on this data publicly available, you can see that
Sandy Bridge can't support 3840x2160 videos.
I'm sorry, thanks for pointing me to these documents. I had only
searched the intel.com website and I was surprised that such data is not
advertised there.
Greets,
Kiste
