You should post questions on the Media SDK support forum

Thanks I will post a question over there.

I already reported the installer issue internally, a fix should be out soon. I don't know when. In the meantime, use v2696. The differences between them are small.
Update: the v2712 was removed from Intel's website.

I got 2712 installed all okay by just moving the Media SDK folder to the location the setup.exe was looking for it and that worked okay, obviously for most people they will not know to do this so good Intel has removed it pending a fix.

A question relating to decoding, is Windows Media Player using the hardware decoding provided by QuickSync? The reason I ask is I'm playing 1080/50p video (H264 Level 4.2) flawlessly with an i7 Ivy Bridge using the CPU graphics when on my prior computer with Nvidia graphics card and i5 (before Sandy Bridge so no QuickSync) couldn't play these files without serious judder and freezing. When playing these 1080/50p files the CPU is around 3 to 5% for the most part, and CPU remains in power-saving mode according to Intel's Turbo Boost real-time reporting app, so seemingly do very little work at all.

Regards

Phil

Windows media player will use Microsoft's own DXVA decoder (Microsoft DTV-DVD decoder). It's not the most robust decoder in the world though...
Other options are FFDShow or LAV filters, both support the QuickSync decoder (most stable and allows subtitles in any player) or LAV using DXVA. ffdshow-DXVA is not stable.

Version 0.32 beta is out with the following changes:
* Added HW deinterlacing - can't be disabled in this build. Works on content marked as interlaced. If this version give you problems, please report and revert to the previous version.
* Added support for HW Detail and Denoise filters. Disabled in this build. Need ffdshow GUI for these features.
* FFDShow rev4453

Version 0.33 beta is out with the following changes:
* Support for H264 frame doubling/tripling flags.
* Added forced DI mode - currently disabled.
* Added forced filter order - currently disabled.
* FFDShow rev4455

I'm working on adding GUI to ffdshow and then all new features will be enabled.

Well and update to my endeavors. I finally managed to work on continuing to get QSync to function. I installed the latest version of ffshow and LAV splitter as suggested and checked everything for QSync. Once I started the encoding process I saw a 25% reduction in CPU usage and only taxed the CPU to 75% now instead of 100% as before. Also saw a increase in compilation time from avg. 9-12 minutes for a 1.5g file (before the change) to 59 minutes with new changes. So there was slight gain but more loss then I was expecting.

Can you describe your trasncoding flow (tools, scripts, content type, etc)?

Version 0.33.1 beta is out with the following changes:
* Support for H264 frame doubling/tripling flags.
* Added forced DI mode.
* Added forced filter order
* FFDShow rev4457 with new QuickSync config!

This version has the same QS decoder with upgraded ffdshow.
Control most QS decoder options, including video post processing via a new ffdshow configuration dialog. Look for a new entry just below "decoder options".
Visit the configuration once for your new settings to stick.

That might be a lot bit easier said then done. Transcoding flow, I'm not sure what that means exactly.

System is a ASUS Maximus IV GEN Z/GEN 3, intel i5 2500k

Tools? Not sure what you mean but I was using only MultiAVCHD

Scripts? Don't know what you mean by this term

Content type? I'll take a stab at it meaning file, which was MK 1080p movie encoding. I think MK file.

Sorry for the confusion
Content type is H264, 1080p, 30mbps (like in BluRay) or can be something more modest.
Some transcoding tasks are done via a collection of applications and avisynth scripts (MeGUI is a good example).
Some people just convert using commercial SW, some of which use HW encoding.
Usually the decoder takes a small part (time/cpu) of the encoding process.
If you meant MKV files, they are most likely H264.

Yeah MultiAVCHD is one of those SW apps but not commerical instead it's free and it incorporates ffdshow, Haali, AviSynth into an intuitive graphic GUI.

Plus no need to apologize, all this helps me to learn new terms and more about each.

You need to make sure ffdshow outputs the color space avisynth expects (YV12), otherwise a lot of needless conversions will occur.

FYI, all HW decoders output NV12 not YV12 and avisinth doesn't work in NV12.

Ok just to clarify ...how many people can enable quicksync as an option using the LAV filters with a Celeron G530/G620...etc. Im getting into a pissing match on another forum where everyone is saying you can not use quicksync on any Celeron. I even posted a screen shot showing the LAV config with quicksync as an option.

Video-mode HW deinterlacing works fine as it should do. (Pulldown detection does not work, however.)

Quicksync is selectable and works within the LAV decoder using a Pentium G850.

Will work only in desktop apps. That's the state today but Metro apps may be supported if the Intel Media SDK supports it.

Hello Ericgur. I try use Intel QuickSync Decoder. I use MPC-HC. CPU - Intel Core i3-2330M 2.2GHz with Intel HD Graphics 3000. OS - Windows-7 Ultimate x86 SP1. Play 1920x1080x50i 16Mbits/s video from camcoder Sony CX550.
I download ffdshow_rev4464_20120615_egur.exe from http://sourceforge.net/projects/qsdecoder/. I select QuickSync Decoder and use EVR, but play not smooth. After many experiments I found working configurations - ffdshow DXVA Decoder + EVR, and LAV Video Decoder + EVR. QuickSync Decoder load CPU for 20%, DXVA only 10%. FullHD video play smooth at both variants. But when I put USB-FLASH to my TV-set and run this video, TV play smoother and colors better. I posted this my settings, please check it. May be have errors, and need set or clear some checkbox.... I want that videoadapter switch output freq to freq of input video. Example: file is 50i, HDMI out is 50p; 25p -> 50p... Where I must set deinterlacing in settings for better quality? Or, HDMI can output 50i signal, and deinterlacing will be do in TV?

CPU usage seems fine for a dual core running high bitrate clips.
LAV video decoder doesn't support QS deinterlacing yet. Only ffdshow.
By default DI is off, you can change it in ffdshow's config->Intel QuickSync, right under decoder options.
DI will add CPU usage due to more copying. If you don't subtitles, let EVR do the DI.
ffdshow-DXVA is not maintained by me and it's known to have problems. If DXVA is good for you, try LAV's implementation.
ATM, I don't expose DXVA surfaces to the renderer. Instead I copy them to system memory, impersonating a SW decoder.
Adding more EVR buffers (MPC-HC output) may help stability. Give it a try.
I don't see the difference as to why colors are different when running from USB, it doesn't make any sense to me. Unless it's a really slow USB stick, playback should be smooth in all cases.

I try LAV's implementation, it work very well. I dont understand why ffdshow QS decoder dont play smooth.
Checkbox "Aggressive deinterlacing" in LAV Video dont work when select QuickSync decoder?
In Output Formats in LAV Video may be better select only NV12 and clear other checkbox, or not?

It works smooth for me and most users. If it doesn't for you, please share a clip.
I don't know what LAV is doing with aggressive deinterlacing.
NV12 is the preferred format for HW acceleration and usually asked for by EVR automatically. Some players will tell you what's the connection type.

Ericgur I wonder if you could answer a question I had around the h264 preset profiles used by QS. In programs such as Arcsoft Mediaconverter the only "handle"you have, other than bitrate, is a general quality setting. As you change this setting what are the changes to the actual h264 presets? If I set max quality for example, what is the preset profile QS uses (talking Ivy Bridge here)? Thanks

Sorry, I have zero experience with the encoder. You can ask in the Media SDK forum.
