Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing - Page 6

i have to wait until i build my htpc with i7 3770T then...

Intel should just hurry up with Ivy Bridge already, i sure could go for a new HTPC now, mine broke. :P

Getting replacement parts today, still would've wished i could've just thrown it out the window.

Vote for HW Video processing) (3d noise reduction, unsharp mask, lanczos resize, etc heavy filters).
Also hi10p support will be great (maybe at last partial acceleration).

Can it do interlaced VC1 now? I know interlaced VC1 is a problem for many decoders.

Can hardware post processing be enabled in raw video? Or only for those streams that it decodes?

In theory its possible, however i don't think egur is going to focus on that for the time being. He can comment on that some more, though.

Just finished reading this thread with great interest, but not sure I saw a final determination about whether the CPU I have is fully supported, G620. Is it?

If not, I will buy a new one, but would be really nice if it did as I unfortunately have to save money for some replacement hard drives (have 3 now that are starting to fail).

Just wondering, my main uses are live tv through wmc and playback of local files through plex. Do I stand to gain anything by using this or is it geared towards those playing media with mpc or mediabrowser, etc?

G620 here

Apologies first off if this is the wrong thread for this question? But this seems to be where all the Intel guys are..

I am running this version of ffdshow thru wmc, and it works great.

My issue is I'm trying to calibrate my signal path and have many issues.. I am using the AVSHD disc and it works great thru my PS3, but I am having a hard time setting brightness and contrast. I I've tried the controls in the Intel control panel to no avail.

Is there some setting in this path I need to change alter to mimic what I am getting out of my PS3?

Which driver? I'm on 2509, which is listed as the most current but I'm getting the unsupported error on my g620.

The G620 does not have QS, nor many features that the i3/i5 series have

2509. Yes, the G620 is supposed to not have QS, but for some reason the decorder works for several users here. Running LAV 0.45 and the only not supported message I get is if I try Cuvid (for obvious reasons).

Maybe it's just the QS encoder that is not present in the G620? I have no idea, but I saved 50% on the G620 compared to the i3 2100.

But I did have a set of driver issues. First when I tried the QS decoder i got a lot of video corruption. Then it worked after a driver upgrade. But then Mediaportal crashed on multiple occations so I downgraded the driver and lost QS. After reinstalling 2509 i got the QS decoder back again. Now it has been stable for a while, and i'm very pleased with LAV 0.45 QS.

hmm. I'm on LAV .44 so I'll try updating tonight and see what happens. I'll also reinstall 2509 from the intel site. Pretty sure I pulled it down from the initial windows update on this build.

Dear Eric, thanks a lot for coding this QuickSync module for ffdshow. I'm using a Z68 system, with a Radeon HD 5870. Using HW-acceleration on the HD5870 is such a waste, because it changes clocks from 157/300 to 400/900, thus any power savings from doing it in hardware, instead of software, is gone.

Now I've changed my plasma screen to the VGA output of the HD graphics, and I must say I'm very impressed by the QuickSync plugin. Power consumption is very low, and noise level doesn't increase when playing even demanding videos. As suggested by renethx, changing to the madVR renderer, running on HD graphics, further improves image quality. This makes for a great HTPC setup.

Sounds like a sweet HTPC you've made! Could be a good plugin development computer as well I think it would be nice of Intel to provide you with free SSD's after all the hard work you've done on this plugin.
I've considered pulling the 5870, or using Virtu, since I rarely have time for gaming. But that would require a 5m DisplayPort cable to the U2711...

Our PC's a work, Dell Vostro 460 has the i5-2400 CPU with HD Graphics 2000, on a H67 motherboard. To support the U2711 at 2560x1440 some PCs have a discrete GT420 card too. Now I enabled the HD Graphics in BIOS, and connected the same monitor to the VGA input of the monitor.

Opening a 1080p MKV file, using MPC-HC 1.6 and your ffdshow release, it uses libavcodec instead of QuickSync for decoding H.264. I'm using EVR as renderer. After changing from the Windows Update v2509 driver to a Gigabyte 2559, QuickSync now works! Tried downloading the latest 64-bit driver directly from Intel, but there's a CRC-error in libmfxhw64-s1.dll.

I found a clip that doesn't work properly with the QuickSync decoder. It seems playback is happening at max fps, the 2 minute clip completing in just a few seconds.

I made this QuickSync test to possibly help our graphics guy speed up his workflow, he's exporting a lot of videos using Adobe Media Encoder. Has there been some further QS development done on the prototype encoder, or is there another application that can benefit from the QuickSync encoder? A freeware video conversion app/plugin would be fantastic!

Playing the Hitachi HD Demo in 1080p using MPC DXVA Decoder on the GT420 average 2 % CPU. With ffdshow using QuickSync it averages 5-6 %. With the GT420 increasing it's clocks to 700/800 during playback, I imagine the QS decoder is much more power efficient.

Eric,

I don't have a SNB system to test out off-hand, but can you let me know if your decoder supports decode of 4K videos in hardware ?

Some samples are here:

For the YouTube clips, LAV Video Decoder does software decoding on a Core 2 Quad with 50% CPU utilization and no frame drops. Core 2 Quad doesn't seem to be good enough for the Crowd Run clip.

SNB does not support 4k decoding.
Its not 100% clear if thats a driver or a hardware limitation, although i would put my money on hardware.

IVB is supposed to support it.

I recently tried to enable quicksync decoding on my HTPC and I'm having some problems. I followed the "advanced mpc-hc set up" guide stickied on this forum. All files playback very glitchy... It's difficult to describe, but it looks like frames are repeating causing a strange stutter effect. Not like a dropped frame stutter, this looks almost like a strobe effect, or as my wife puts it, "seizure inducing". The mpc-hc osd doesn't seem to report anything out of the ordinary.

Some info:
i3-2100 with latest drivers from intel
Win7 home premium 64bit
MPC-HC 32bit
LAV filters v.0.45 32 and 64bit components installed
MadVR
no other codecs installed

Disable quicksync decoding and playback is fine. Disabling MadVR and enabling EVR had no effect, re installed each component, many system reboots, still nothing. Also removed lav video decoder and installed ffdshow quicksync, same issue. Problem effects all video stream types, h.264, mpeg 2, and VC1. I have a feeling I'm missing something obvious here but I have no idea what. I've spent the last few days going through each and every setting screen of every component and I'm stuck.

Thanks for your time,

Josh
