1080p mkv file problem (MC and MPC-HC)

[bliving]

hi,

1. Windows Media Center(x64) plays 720p mkv files fine(no dxva though). but 1080p files give choppy playback(not watchable at all). How to fix 1080p playback?

2. 720p mkv uses dxva in Media Player Classic-HC(x64), 1080p doesn't. anyway to force dxva?

I have haali media splitter 1.9.63.13 and MPC-HC 1.2.1164(x64)

please help.

Is the 1080 file you have DXVA compliant?

 

[bliving]

I think so, because in Windows XP it used DXVA.

I would make sure, use Gspot or something equivalent to that and see if the profile is 4.1 or lower.

 

[bliving]

Gspot doesn't show anything for both 720p and 1080p.

Hmmm it might have problems with windows 7, try Media Info i guarantee it will work.

Unless things have changed and they often do, you shouldn't be getting DXVA on either of those. There are other factors to consider as well for compliance such as ref frames etc. I would of thought your processor would be capable of either files but you could try CoreAvc it is a very efficient codec and can use Cuda for Acceleration as well. Other than that the only thing i can suggest is to ask on Avsforum or Doom9.

Thanks! I'll ask.

i say get coreavc and don't bother with dxva. my processor isn't great either but i run 1080p with no problems just using haali + coreavc in mpc-hc.

Hi garbonzo,

coreavg doesnt work on WMP under Windows7 RC1.

How could you work it under Windows7?

Thank you.

Hi and welcome to SF

Have you upgraded the driver for the vid card?

hi matchbox,

no need to post twice. patience is a virtue

CoreAVC works fine in windows 7. i use it with Media Player Classic rather than WMP, it's a much more powerful app that gives you fine control over how video is displayed on your system.

it may work with WMP too, i don't know. try searching the form, there are dozens of threads about watching HD videos with WMP...

Sory for the twice post.

I prefer using WMP rather then using Media Player Classic.

But coreavc codec doesnt run when plaving mkv. WMP using native codecs and prevent other third party codecs (coreavc,ffdshow) for mkv.

How can I handle this?

As he said try searching the forum, and if you don't find anything start a new thread about your problem (instead of hijacking one).
