Already supported.
Needs a recent enough driver to work properly though, 2696 seems fine.

Is it active if VC-1 is checked for QS in LAV?
May I ask why there is no extra checkbox for it?

[nevcairiel]

VC-1 is WMV3 Advanced Profile, and WMV3 is VC-1 Simple/Main Profile. Its the same codec, just different profiles of it. Doesn't make sense to add an option for that.
Also, there is little space.

[aufkrawall]

Alright, thanks. Will check it out.

Just out of curiosity is it 3D capable? Would you mind sharing size and model?

I got a Sony KDL-55HX755.
It is 3D capable, and i briefly tried the 3D, and quickly hated it. Was more fun in the cinema.

Other then that, i'm pretty happy with it.

egur, there's still something wrong with MPEG2 interlaced.
With EVR CP of MPC HC it still jitters but it's deinterlaced.
With madVR it doesn't jitter but the stream doesn't seem to be marked as interlaced so madVR doesn't deinterlace it.

Nice one, have fun with it.
It's normal to not like the 3D on size this small ... and on LCD TV. You should try it on a 100+ inch screen at a 1x width distance and of course with a bright projector not like most cinemas.
but I won't hijack the thread with this any more.

Question to the IVB owners:
How does it work with 4k?
Maybe even with 60fps?

FFDShow or LAV?
Could be that the iGPU isn't strong enough for this setup. I had many performance issues with EVR-CP.
My favorite setup is EVR + vobsub (v2.0 or newer) for subs.

I tested it with the toughest clips - works very well.
The hardest clip was 4K@50fps with ultra bitrates (>200mbps).
The test machine was a laptop class i7 and 1333MHz ram.
4K really stretches the memory subsystem and implies that I need to export DXVA surfaces to avoid copying.
This will be the next big feature after deinterlacing is fully functional. I need to work out the details with Nev so this will go smoothly. DXVA implies some changes on how a DirectShow decoder works.

Also on the TODO list are (random ordered):
* Support MVC (H264 stereo and MVC profiles).
* Support MJPEG - MSDK 2012 added this support, usually an indication for future HW or driver support.
* Support scaling - may provide a significant performance boost for 4K clips for users with a smaller resolution display (currently 99.999% of users).

I use a dedicated graphics card and QS via the multi monitor trick.
Since VC-1 interlaced works, I suppose it's just related to MPEG2.
Not a drama, every phone can play 1080p MPEG2 in software (even that old ones with a turntable ).
But it's a bug and why not fix it.
I use LAV but afair it happened with ffdshow too.

Nice to hear. So, if I'd play a 4k 60fps H.264 movie, it should simply work with QS via LAV?

That is a nice todo list.
Although I'd let madVR do the scaling with a Radeon HD 7770 if I created a HTPC.

Hopefully with Haswell a dedicated graphics card will be completely superfluous for HTPC.

Eric,

could you please test two more "special" 4K clips ?

1) http://p.gokuai.com/index.php?m=Inde...5Yj637KS6yyu75

This is a 4096 x 3072 H.264 clip at 117,586 fps and very low bitrate 6.6Mbps.

The "special" thing about this clip is the ultra high resolution and frame rate.

2) http://115.com/file/clozg3pv#
Girls.Generation.Oh.4in1.201002.HDTV.x264.2160p.120fps.DTSES.6.1ch.part1.rar

Girls.Generation.Oh.4in1.201002.HDTV.x264.2160p.120fps.DTSES.6.1ch.part3.rar

The way to download them

That is a huge clip:
Girls Generation Oh 4in1- 3840x2160@120fps-Ref16-100Mbps

It has a resolution of 3840x2160 at 119,880 fps and 100Mbps bitrate.

Both were indicated by wanezhiling.

Good luck!

[egur]

The bitrate is not a problem for QuickSync. Clips with 300-500mbps played fine.
120fps? I don't know. Should be in DXVA territory. I'll give them a try when I'm in the lab.

Though this isn't a real 4k source right but upsampled ? i mean which consumer satellite these days transmits 4k 120 fps Progressive yet, anyway this will be one of the common big problems 2x times the resolution but we hardly gained 50% reduction and the bandwith will be enourmous just for normal nice playback without 120 fps ?

@egur

as nev said i tested under win7 and it was also ok according to the readme todo so as the driver was also for win7 despite the way it was categorized in the downloadcenter. The problems for now are mostly Video Related QS not working and Adobes Flash Player makes problems (shows some strange black stripes over the video surface renders sometime very weird Video results), if those are really known Win 8 optimized caused issues the driver shouldn't be allowed to install under Win 7
D3D 9 seems stable and slightly improved (especially latency feeling on Aero) but D3D 10 seems to suffer from Render issues http://img14.imageshack.us/img14/137...ssuewin7sb.png (could explain the much lower Game Graphic Benchmark Value in the Windows Performance Index with this Driver, compared to 2719 which doesn't show these D3D 10 Render issues i encountered, though it's hard to categorize these as they are random happening also how they look, sometimes i get flickering black stripes)

So yeah on SB Win 7 it's not overall stable, but it shows some nice improvements that i would like to see in the new Win 7 driver also (Aero subjective Performance improvement, faster mode switching times)

[egur]

The Win8 drivers are still in Beta and have an issues list a mile long (according to the release notes)...
I might be able to get hold of a Windows 8 system and start testing, but it will not be soon. I'm too busy with another project. At home I can try this driver family (15.28), but I'll wait for another release or two.

Motherboard: MSI Z77A-GD65
OS: Windows 7 Pro 64-bit SP1
Driver: 8.15.10.2712 (link: http://downloadcenter.intel.com/Deta...adType=Drivers )
ffdshow: ffdshow_rev4441_20120430_xhmikosr_icl12.exe (I can give your build a go if you want to)
LAV Filters: 0.50.2

Does it require lucid or something?

//Danne

I've been doing a search on just this issue as have the same problem. QuickSync isn't being shown as available to any software. This is an i7 3770 (not K), Intel DZ77BH-55K motherboard and the latest 8.15.10.2712 drivers on Windows 64bit, no other graphics card.

Did you find a solution?

Edit: Solution, there is a bug with the driver installer, see here for a fix: http://communities.intel.com/message/156486#156486

I tried running the installer and didn't get any warnings or errors (SandyBridge, Win7 SP1 64 bit). Used the installer from the link you posted (Intel Download center).

Maybe the installer was updated. Can you download again and compare the files.

The config.ini file you refer to doesn't contain paths. All the files are located relative to setup.exe so it doesn't matter were you extract the files to.

Please try again, and if you get errors, let me know.

[nevcairiel]

Must be a bug in the 2712 installer, never had any such problems with 2696 or any previous drivers.

Have a look in the route of c:\Intel there are some Log files, it is in there it mentions a problem finding the SDK, however....

I suspect if you already installed an older driver that worked you will have the SDK files already (albeit perhaps older ones), and these might be left in the correct location and are found by this installer, so as you update QuickSync still works based on previous installations of the SDK.

For me it fixed the issue, and I'd already tried several un-installs/re-installs. This was a clean install of Windows 7 on the Ivy Bridge and I'd only ever installed the most recent graphic drivers.

I'll download the one there now and check the Hash's and see if they have changed it since I had got it.

Edit: The current file for download is identical to the one I downloaded and had issues with.
