I've installed latest iGPU drivers for my Pentium G3420 yesterday - v.3412 - and find out today two extraordinary things that I would never expect.


1) QuickSync transcoding - yes decoding and encoding - is available for the first time in a Pentium CPU (Haswell-DT core) !!


I tried it and it really works!


QuickSync encoding with Pentium G3420!


2) HEVC_VLD_Main appeared while enumerating DXVA device decoders !!




How on earth could a Haswell iGPU offer HEVC_VLD decoding ?


We have to wait and see!!!

Yes, it looks like that.


The only way I can think of Haswell decoding H.265 in HW, is by utilizing the EU's - meaning the programmable HW of iGPU.


Because the fixed-function QuickSync ASIC, is built for H.264/MPEG2/VC1 and MJPEG only.


I don't know if Intel could use some of the fixed-function logic of H.264 HW decoder for H.265.


These two algorithms have many things in common, but they are different.

Finally, we have official support of HEVC GPU accelerated decoding in latest 3621 Intel's driver.
Quote:
HEVC decode now supported by the driver and video players can now take advantage of the GPU accelerated decode support offered by Intel
Quote:
Transcoding to HEVC is currently not supported.

It's time for video developers to implement it in their decoders, in order to check it out!
