Author Topic: How to get your (supporting) video card to decode h264 using DXVA (Read 76729 times)

I think I'll just stick to the setting I already have. DXVA w/VMR9 on XP doesn't seem to support all types of 1080p videos (but Win7 does, why? perhaps DX11). If I encountered a 1080p video not supported by DXVA I'll just run CoreAVC.

It's probably because of Windows XP drivers limitation.

Depending on your CPU + GPU, you should always use CoreAVC + VSFilter, in that case.

~~How important is having ffdshow tryouts, Gabest's FLV Splitter, Gabest's MPV (MPEG-2) Decoder, and VSFilter installed alongside the latest build of MPC-HC?~~ I'll make that in a separate thread.

First, install the latest CCCP. (you shouldn't need to use the latest SVN builds, you just need to use something that is stable)

Here is my 'guide.'

Thank, I'll try your guide very soon and report what happens.

Probably no difference for XP as I already said everything above. D:

Do you mean I will still encounter the problem?

"DVXA Cannot decode videos that was encoded with numbers of reference frames that exceed certain levels." [taken from here]

what is reference frames? and what are the certain levels?

namaiki · « **Reply #87 on:** February 10, 2010, 09:48:43 AM »

The limitations will still apply.

Depends on the video card and other things, though I really don't know.

Is it true that using CoreAVC instead can decrease quality?

The image produced from any decoder should be identical, except where there are features not supported (or bugs) like in CoreAVC 1.x with weightp.

Do you have an nVidia video card?

CoreAVC 2.0 in Winxp fails at decoding some h.264 files such as http://bakabt.me/148848-elfen-lied-h-264-dvd-akh-anisubs.html
To play it correctly you'll need to either: disable CoreAVC from external filters or enable internal DXVA instead.

Yes 9500GT CUDA enabled. But I wanna utilize internal DXVA.

namaiki · « **Reply #91 on:** February 10, 2010, 10:00:33 AM »

Which version of CoreAVC?

Xemnarth · « **Reply #92 on:** February 10, 2010, 10:01:06 AM »

latest 2.0 professional

vuzedome · « **Reply #93 on:** February 10, 2010, 01:15:25 PM »

You'll need to update your graphic drivers, because as of 19x.xx something, DXVA works on all AVC levels for supporting nVidia graphic cards(such as yours).

You're not the only one, there have been reports of CoreAVC 2.0 loosing backward compatibility with some older versions of x264, its developers really know (?) what they're doing...

I followed you guide for configuring MPC-HC on XP, and I haven't encountered any problems for H.264 / DXVA , using nVidia 8800 GT.

The cpu utilization (Intel E8400) fluctuates between 2-10% but mostly 4% for Sky Crawlers 1080p H.264 [3xR].

very impressive.

Yes namaiki's guide works.

can you try niizk's ponyo 1080p release and see how it goes please? would really appreciate it.

I couldn't get DXVA to work with ponyo_on_the_cliff_ by_the_sea[1920x1040.h264.flac.ac3][niizk].mkv

In the status pane of MPC-HC it should write [DXVA], but it doesn't.

Same setup, cpu utilization ~30-40%

Xemnarth · « **Reply #99 on:** February 10, 2010, 04:10:27 PM »

yes it doesn't work here too
im using amd 64 athlon x2 + 9500gt + 3gb ram
there is a issue with the vmr9 renderless renderer i guess. evr cp can play ponyo on win7.
