Need a H.264 Decoder (DXVA) that properly decodes movies

I think the picture above is self explanatory. That picture corruption always occur when default MPC-HC decoder is used. And many times, movies also get blocky and pixelated.

Another DXVA decoder I had tried was Microsoft DTV-DVD video decoder which produces picture as good as FFMPEG. However, the downside is it sometimes fails to play anamorphic videos in their proper ratios.

I know that I can always use FFMPEG or FFDSHOW software decoder but seek time is really slow on my old laptop. Also, some HD movies can use 100% cpu and things go very sluggish.

What card do you have and what driver version do you use?

[Cyber-Mav]

coreavc's cuda mode should do the job.,

I afraid I could not use that since I do not have Nvidia GPU.

What card do you have and what driver version do you use?

It's Intel GMA 4500MHD with latest driver (8.15.10.1986). From what I've read this GPU supposed to be fairly good in video decoding (correct me if I'm wrong).

try DivX h.264 decoder or DiAVC decoder (http://forum.doom9.org/showthread.php?t=143455)

also post MPC-HC bug report here, sample and MediaInfo will be nice

Which version of MPC-HC are you using?
Anyway this is a really strange problem...maybe a video driver issue?

Is Di-AVC safe to use? I got this screen when I tried to download it.

Anyway, it says on homepage that Di-AVC is a software decoder, it's probably not DXVA compatible.

I'm using version 1.3.1426.0. I've always kept MPC-HC (also my video driver) up-to-date in hope that there's a fix to my problem.
I'm not really certain on what caused this picture corruption. I suspect MPC-HC decoder is at fault because another DXVA decoder (Microsoft's) works just fine (except aspect ratio issue).

powerdvd has a dxva decoder i think, give it a test?

[littleD]

Try the most recent version of MPC HC.

[nurbs]

He'll need a time machine if you want him to use a more recent version of MPC-HC than the one that was released today.

Give Arcsoft Video Decoder a try too. I'm using that for all my H264 decodes and yes it uses DXVA. It's the only one that works perfectly for my ATI card.

I installed PowerDVD trial version but couldn't find its H.264 decoder to use with MPC-HC. I can use its MPEG-2 decoder though.

How can I get it from Arcsoft? They do not offer video decoder for download. Is it bundled within some of their softwares, if so, which one should I download: ShowBiz, TotalMedia, or something else?

Unfortunately newer versions of Cyberlink PowerDVD / Arcsoft TMT don't allow their H.264 decoders to be used in MPC-HC. You've got to get one of the earlier versions. Some versions of PDVD8/9 and TMT 2 have it.

@ mk.2 - "Avast" - find your problem here, report false positive ;)
diavc.ax is decoder and this file you only need
DiAVCSetting.exe is program to change decoder merit and register it to system...

PowerDVD is not good, it dont play many files, DxVA as I remember didnt work propetly with some files causing black screen... of course in the latest version that connect to MPC-HC...
dunno about ArcSoft, but probably the same

Can someone know maybe the latest version (link to pack, cause I will extract decoder with Universal Extractor will be usefull) ?
Because I want to try some new tests ;)

This was already discussed and resolved. See the DiAVC thread!

(I got reply from the Avira AntiVir developers. They said it's a FALSE POSITIVE and that it will be fixed in the next signature update. You should do the same: Report the problem to Avast)

BTW: Was the DivX H.264 decoder mentioned in this thread? It's free and it's definitely fast!

I found trial version of TMT 2. The program itself does not work well with W7 but its decoder works fine. There's no corruption or any visible pixelation. However, Arcsoft's decoder suffers the same problem as Microsoft's decoder; wrong ratio in anamorphic videos, which I later found out that actually caused by MPC-HC internal MKV splitter. I installed Haali Media Splitter and problems solved. Now I can use either Microsoft's or Arcsoft's decoder without ratio problem . Beside both of these decoders can decode MPEG-2 using DXVA as well (though I don't need it).

:thanks: Thanks you everyone for your inputs.
