Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing

Quicksync is confirmed for Intels next gen Atom tablets. Newest Media SDK support it. The fixed function unit is highly power efficient and fast.

What? You mean you can't just put in a new hardware request at work?

Every smartphone and tablet nowdays has hardware decoding/encoding capabilities.

For example my Note II can hardware encode/decode H.264 up to 1080p@30 fps (Bluray compatible).

The GPU is Mali 400MP4 (4core)@533 MHz.

My benchmarks say that HW decoder is 100% faster than the optimized software decoder running multicore and using SIMD NEON instructions on a quadcore Cortex A9@1.6GHz (Exynos 4412)

So, Silvermont will definitely have a HW decoder.

But even if you or Intel call it QuickSync, what are the characteristics and performance compared to Ivy's QS which is more than capable of even 4K H.264 ?

I don't know the performance of the yet-unreleased Bay Trail. At this point in time it's not important (SW stack may not be optimized enough). Performance is relevant near launch. By then, they will be disclosed.

For people who know Chinese, first review of Haswell is here:

http://www.chinadiy.com.cn/html/24/n-9024-7.html

It's a 3770K vs 4770K comparison.

Even if you don't know Chinese (like me) you can read the numbers and the names of benchmark applications (they are in English).

I worked out an initial version of QS that supports D3D11 HW video decoding (alternative to the limited D3D9).

Direct3D11 provides headless (disconnected iGPU) video acceleration. This hopefully solves multi-GPU setups. Media servers also enjoy this (no screen at all).

Minimum requirements:
- SandyBridge or newer (like before)
- 15.28 or 15.31 driver.
- Windows 8 (D3D11 and D3D9). Windows 7 (D3D9 only)
- 32 bit player
- LAV (32bit) and/or ffdshow (32bit) installed

Get the DLL from here. Rename the original IntelQuickSyncDecoder.dll file and use the new one instead.

This is an "alpha" SW, not well tested, etc. Please provide feedback.

My test system:
- Win8 Pro 64bit fully patched
- 2nd generation Core i7-2600 (SandyBridge)
- Radeon HD 6950 (connected to display), Catalyst 13.1.
- Intel HD 2000, latest 15.28 driver.

Update
The above DLL was updated (link updated too) and now it works on Win7. VC1 playback (D3D11) is operational too.

Hi,

thanks for this testbiuld.
I did a quick test, but on my system it's not working yet.

Win732bit
LAV 56.2
Intel HD4000 15.31 driver
AMD HD6570 CCC 13.1
DVBViewer Pro

Quicksync is shown available, but avcodes is stilled used. Same problem with ffdshow (your latest build).
Anything else that have to be done instead of replacing the IntelQuickSyncDecoder.dll?

That's great news. I've been anticipating headless support for a long time, and we have it now. Thank you.
Though, it is not working on my system. Whole setup below.

System: Windows 7 x64 SP1 with almost all updates including KB2670838.
Hardware: Intel HD Graphics 2000 + GeForce gtx 470.
Drivers: Intel 15.28.15.64.3062 (9.17.10.3062) + Nvidia 314.07
Software: Daum Potplayer x86 + LAV 56.2

That is some inconsistent test. Turbo issues on Haswell, oddly high 3770k results and so on. Here is a better one: http://diy.pconline.com.cn/329/3297240.html

Pretty good GT2 results and convincing system power improvements.

Headless only works on Windows 8.
Windows 7 lacks the required D3D11 support.

[egur]

Correct. Headless works only on Windows 8 (d3d11).
Windows 7 users should check that what worked before still does.
My own Windows 7 HTPC works fine with the new DLL as far as I could tell.

Full Screen Exclusive (FSE) layers like Windows Media Center do not exist on Windows 8 as far as I know. Please correct me if I'm wrong. That's why I don't know if D3D11 works in FSE applications.

[wanezhiling]

Wow a good reason to convince myself to win8?

[RBG]

This is sad. I wonder if it is technically impossible to fully port D3D11 functionality or it is just the way Microsoft is doing business... Well at least I can buy Lucid MVP, cause there is no way I am going to buy Windows 8.

WOOOWWW great news ! Thank you guy !!! Can't wait to go home tonight to test it

Lucid MVP needs a GTX geforce model. I bought it before understanding that i needed a GTX. So if you want i can give it to you........the standard edition

Parts of these functions need the new driver model WDDM 1.2 which is not available for 7 either, so they would need to port this as well, and who knows what all else this contains and how deep it goes.

So one can understand why its not done, even if it makes us sad.

[itsonlyjustincase]

Unfortunatly doesn't work with my app. It uses avcodec when i select quicksync

WIN8 64 bits
Asus ux32vd

[egur]

Please specify your setup - what SW is used (must be 32 bit) what driver? Is the iGPU enabled?

[itsonlyjustincase]

win8 64bits
i7 3517u
intel hd 4000 + nvidia geforce 620m
intel hd 4000 enabled by default.
Geforce 620m forced to use my soft Serato Video 32 bits (www.serato.com) cause they disabled intel gpu compatibility so that you can't run the soft using the intel GPU as it gives you an error message saying your intel gpu isn't supported. That is why i wanted to be able to launch it with the Nvidia GPU but use quick sync to play video
Driver 9.18.10.3071
