What software pack need for GPU HEVC (8-bit) decode on HD4600? I tried MPCHC1.7.10+LAV - quicksync not available...

[NA1]

I'm use last version Intel drivers for HD4600 for Win 8.1. Intel the declared GPU accelerated decoder for the 8-bit HEVC streams. And, pls, get me right settings for this software pack. I get demo content from this site:http://demo-uhd3d.com/ Demo UHD-3D - Ultra-HD / 4K / HDR / 3D

Hello MadToster,

Thank you for joining the Intel communities.

Since consumers expect to optimize their media applications for all types of devices, it's important to look at the capabilities of the recent generations of Intel processors.

1. 4th Generation Intel Core processors (Haswell CPU 2- 3.5GHz, 4 Cores): Includes an HEVC Software Decoder capable of real time decode of HEVC 4K streams.
2. 5th Generation Intel Core processors (Broadwell): Supports HEVC 8-bit software/hybrid encode.
3. 6th Generation Intel Core processors (Skylake) Supports hardware accelerated HEVC 8-bit decode and encode.

You can see more information related to this at the following link:

It's wrong info.

Real info is here:

I tested with this version and newer - it not work. How to make the claimed by Intel ii will work? And with any set of programs it will work? I have i7 4700HQ. Software decoding in MPC-HC+LAV Filters worked with 8/10-bit/50Mbit/s H.265 demos (55-70% cpu load). 80-120Mbits (8-bit) not worked. Intel promised to work with any 8-bit hevc content on HD4600. At a minimum, meet the specifications UHD BD/8-bit (because the restrictions for bandwith are not listed in the table for 15.36.14.4080 version and newer). But I do not turn-on GPU acceleration, but this should work by Intel claims...

In this case, let me investigate on this and as soon as I get information how you can get the correct settings I will post it here.

Hi,

On Haswell and Broadwell, there is no Fixed Function HEVC Decoder logic.

So hybrid mode is used. At a high level, CPU and GPU EU are used to perform decoding functions.

CPU handles VLD, EU handles Post-VLD, with kernels, no Fix Function involved.

Regards,

Ivan

Hi, sorry, I was a very busy and not read the your answer.

Your answer mean that info from /thread/59216 -NEW- Intel® Iris™ and HD Graphics Driver update posted for Haswell and Broadwell version 15.36.14.4080 (see link above) not correct?

If not correct and using hybrid decoding, you maybe take me correct setup info for good perfomance for H265/8bit/4:2:0 (with 50-160Mbit/s average video bitrate) under

Windows 8.1? What video driver version need, what software players (MPC-HC with LAV is good choice?) and what correct setup i do it, for example, into MPC-HC 1.7.10 with LAV 0.67 (what internal settings will correct for use with HYBRID(CPU/GPU) for H265 decoder on 4700HQ with HD4600 GPU)?

I tried select in LAV Video Filter quicksync - it not worked (worked with 1080p H264). I tried DVXA2 in LAV Video Filter + Output (EVR(custom)) in MPC-HC 1.7.10 - sign "H/W" in mpc-hc status bar is On, but video is freezing (low fps) and cpu usage not exceeded 50%. It strange result. In fact - hybrid decoder for H265 not work with 4700HQ by using last drivers from Intel.

Please, get me 100% worked software setup for Windows 8.1 for H265/8bit/4:2:0 brand demos (with 160Mbit/s maximum bitrate - specification for Main HEVC Level 5.1 mandatory)...
