Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing - Page 7

I can confirm this myself, I was having exactly the same issues, driver said it was the latest but I downloaded and installed from the Intel site instead and my problems went away.

New driver fixed my problem. Thanks!

@ericgur

Will you check BBC Life Dics 4 Plants (1080i60 VC-1)? I see lots of block noises with QuickSync. It plays fine with WMVideo Decoder DMO (as well as ArcSoft/CyberLink decoders). A 2-min clip for you.

Thats a horrible file host, i wasn't able to download that file, it kept redirecting me to the waiting page.

But i would wager its the known issue with interlaced fields, which supposedly might improve with an upcoming driver.

Eric:

Let me start by thanking you for your work on this project. I am an audio - video enthusiast, and have built several PCs in my life. Most recently I built an HTPC using the Intel i3 2105 Sandy Bridge chipset. I have no video card - or audio card. Gigabyte mobo. I have read through the thread several times - and have made modifications to the computer per the recommendations here. Latest drivers from Intel - ffdshow, LAV, and the media player (MCE?). I get it to come up out of XBMC whenever a 1080p MKV is selected. Quicksync is selected in the LAV software. And - to your great credit everything works fine.

I must preface this next paragraph to explain that I understand well over 10% of what you people are talking about on this forum. So - let me get to the point. I (Captain Ahab) am pursuing the magical 24Hz (Moby Dick) 1080p playback. Before I took on the Quicksync stuff - I would select the option in XBMC to match refresh rates - and the playback at 24 Hz would be stuttery - not from an audio perspective - but almost like you were watching flash cards from the video perspective. Selecting Hardware acceleration (given that I do not have a video card) made it worse. This lead Captain Ahab onto this QuickSync forum.
Yet Moby Dick still eludes me. When I am playing a movie - all the data on the screen - when I hit "o" tells me the movie is like 23.997 Hz 1080p. My projector says it is 1080i 60 Hz. When I try to match refresh rates in the LAV software (ELV - or something) the option is greyed out - I cannot select it.
Please direct me to what I am missing - and dont be hesitant to dumb down the level to that of a Kindergartener.
Thanks

Hi Eric,

First of all I would like to thank you to enable us to take profit from our HD graphic units!

I am however facing a very anoying problem. As far as I know, the way to enable the quicksync hardware on a z68 motherboard together with a discrete graphic card is either to connect the hdmi output of the motherboard to a display or to use the "detect" button on the resolution control panel (cableless setup). Unfortunately, I my only hdmi display input is in use by the discrete graphic card, so I cannot use the cable method (my display does not have any other digital inputs).

The "detect" method is not working for me. When I click on detect, the control panel only shows an unconnected display of my discrete card (GTX560), but the hd graphics output is missing. I have the newest HD graphic drivers installed (2559) together with the newest nvidia drivers. The HD graphics is enabled both in the motherboard bios and in Windows (I tested it by directly connecting it to my display instead of the graphic cards: in this case, the quicksync acceleration is available, but my discrete card is not used).

Do you have any idea of what am I doing wrong?

Thanks!

I have a different motherboard then you but I did run into a similar problem. I had to enable in my bios a setting called "IGD Multi-monitor Support" or the bios would not enable the integrated video card if I didn't have an HDMI cable connected to it.

Thanks for your answer. I have a gigabyte Z68 motherboard with standard bios (no UEFI). I have enable the "equivalent" option (which refers to the activation of iGPU to enable multi-monitor setup in windows) with no success.

Considering that the cable setup works and that my display has an additional VGA (analog) input, do you think if I connect a HDMI to VGA cable from the motherboard to the display, at least windows would realise that the iGPU is connected so that quicksync can be enabled? I assume that no analog signal can be ouput through the HDMI motherboard output (so no image will be displayed), but maybe at least the signal pin would be activated...

Thanks Eric.

I've installed Lucid Virtu but, If have understood it correctly, having the main display connected to the discrete card, I can program it so that the mediaplayer uses either the iGPU or the discrete one, but not both at the same time (iGPU for decoding and discrete for shaders/rendering). Is it correct?

Regarding the hardware solution, considering that the motherboard output is HDMI only, do you know if a solution like the VGA dummy may work also for HDMI?

Thanks!

hi everyone
i have a problem in enabling "intel Qsync" in ffdshow filter
my cpu is 2500k and oced at 4.6 ghz and os is win 7 x64
vga is gtx 560 ti and it's the master adapter(monitor cable is connected to it)
when i try to set "intel Qsync " in ffdshow codec page there is nothing for selecting it(see below)

i installed igpu driver and it's up to date
ffdshow filter is a part of klite codec pack 8.6
how can i fix this problem?
thanks in advance

Unless your using the Intel GPU, Qsync is of no use as your primary vga adapter is set as being the NV 560

Hi Ericgur,

I've been unsucessful enabling QSync with MultiAVCHD. I use MultiAVCHD for all my HTPC needs because of its Blu-Ray file compiler feature. I have an Intel i5 2500k processor on ASUS Maximus IV Gene-Z/Gen-3 board. I also have the Intel IGPU enable in the bios and the Intel IGPU drivers loaded. I use an older verison of FFDShow which only has Intel QuickSync check boxes. I had installed a newer verison of FFDShow but it would load everything it found on my drive (and not just one folder) whenever I tried to add a file for processing. So I went back to the older verison.

MultiAVCHD works fine but my CPU is still taxed to 100% so the QSync feature is not being utilized.

Is this a problem with MultiAVCHD or the older verison of FFDShow or something completely different that I'm not aware of?

Thanks in advance for any help.

[quote=ericgur;21980470]Loading all the files is not ffdshow's fault - players fault. ffdshow doesn't load files (except subtitles).QUOTE]

Ok my mistake. I thought I had read on one of the FFDshow update versions the incorporation of a file loader that would load all the files from a selected folder.

In any case I haven't gotten around to trying the fixes you mentioned but maybe this weekend when I have more time to dig in if things don't work right and get messy.

But you know my true pursuit of this whole QSync process is for faster Transcoding and file processing to Bluray folder compilation. My present HTPC rig compiles a 1.5gig file in about 9 minutes. So I don't know that having QSync enabled and working is actually going to gain me much faster compilation times. I know and understand it will free up my CPU from being 100% taxed but does the IGPU truly calculate and perform compilations that much faster?

Hey Eric,

first of all thanks for your effort creating this.
Now my question: I've got a core i3 2100 on an asrock h67de3 mainboard and lav 0.5.5 installed to use it within mediaportal.
In the lav configuration I can choose the iqs hw acceleration but in the field "decoder" below it always says "inactive" even if mediaportal is playing tv.
For me this looks like iqs is not being used especially because the cpu load is on the same level as without any acceleration (it's a low level but anyway...).
I've got the last bios version, the newest graphics driver and I don't know what to do else...

Cheers,

Rico

It would only show anything else then when Media Portal would manage to show the settings page of the currently active LAV Video decoder. However, Media Portal is not capable of this, it'll always create a second instance of the decoder to show the settings page.
means no decoder is active, no software decoder, no hardware decoder, no nothing. So it does not mean that QuickSync is not active, it just means that nothing is being decoded at all (by this LAV instance)

This means that it'll never properly show if the decoder is running.
As long as it says "Available" next to the dropdown when you select QuickSync, it should be fine.

It does say "available" so I guess its all right then...
Thx

Hi


Is there a white paper or some API details on how to update the samples in the Media SDK to support encoding to Blu-ray/AVCHD? I can get the sample_encode working fine but it lacks covering all the parameters required for Blu-ray. Yes I could buy a third party solution but if I can do this myself, obviously the money is better in my pocket!

Also not sure if anyone has picked up on my post in the Intel support forum but the graphics install from Intel for 64 bit (may applied to 32 bit as well) on HD 4000 driver version 2712 is broken. On a clean install you will not get QuickSync working. See original details here http://communities.intel.com/message/156508#156508

Phil
