CoreAVC / DVXA Problems.
 

Just to the point. I'm just recently re-install my Windows (from XP to 7)
And I have a problem with all HW Acceleration playback method, yeah its make my processor workload reduced but the video itself became so slow but the problem is only exist when I play 1080p videos and if I'm let my processor decode its run smoothly.

I'm not new to this things n already recheck the everybody knows guide but I'm still clueless about it.

Thanks in advance if anyone can help.

EDIT : and I'm already try to disable Aero and no result.

What is your CPU and GPU?

Also, how about when you use Media Player Classic Homecinema with default settings?

X2 550 and 9600GT
Its run smooth when I'm disable CAVC/DVXA.

Proof I can activated CAVC/DVXA.

However the playback is so slow..

Is DXVA fine on your 720p videos?

Right its only persist in 1080p videos, its not like this before I'd change my OS.

Btw already uploaded the pic.

How much RAM does your 9600GT have?

512MB ?
VGA memory or ?

Could you open the video in MPC-HC, press Ctrl+J, play the video around a slow part and upload a screenshot.
If you only disable CoreAVC/the DXVA filter and keep the other settings intact, is playback back to normal?

There it is.

Wow surely there something wrong.Yep.

Try View-> Renderer-> Reset-> Default.

Also, did that particular video work when you were using Windows XP? Have you tried other 1080p videos?

Which version of nVidia drivers is being used on your computer?

Already did, no result.
All my 1080p videos working fine in XP with Core AVC 2.0 now its suffer very severe lags.Latest. 260.99 version.

What about: View-> Renderer-> Reset-> Optimal.

(by the way, I am out of ideas :p)

Already did too.

Yeah, I'm getting tired too lol... Thanks for your try anyway.

Maybe later I'm gonna ask that tutorial maker blogger or worse, revert back to XP. *sigh*

Hi,

May I ask what other codecs and/or codec packs (K-lite, CCC codec pack etc.) you have installed on your currrent Windows 7 installation? There's perhaps some conflict between codecs or something like that?

For the time-being, uninstall the codecs and/or codecpack you are using, use a tool that's called the CCleaner and use the built-in reg cleaner to clean up the windows registry(make backup of the windows registry first via the CCleaner tool). You can download CCleaner here: http://www.piriform.com/ccleaner

And then try to update to the latest codec pack (K-lite or CCC codecpack) and reinstall coreavc etc., see whether the problem is still there. Also you can update the Geforce drivers for your videocard, it may help. There has been an update recently, Forceware 266.58 WQHL.

As for MediaPlayer Classic's built-in DXVA support, perhaps you should use Microsoft's Media Foundation h264 decoder instead and see if works better with the 1080p videos. You can use the tool, Win7DSFilterTweaker, to switch between ffdshow, coreavc (when installed) and Microsoft media foundation H.264 decoder in Windows 7.


Hope this works for you.


Good luck!

Well turn out its 260.99 driver problem, I'm rollback the driver n its fine.
Thanks for the input anyway.

At least you got it fixed. Which driver version are you using now?

258.96

Btw is Nvidia driver jump that much in version number ?


if not, why the hell when I visit their site few weeks ago its show that 260.99 as the latest.

From http://www.nvidia.co.in/Download/Find.aspx?lang=en-in

Did you try 266.58?

I use a 9500GT/512DDR and Run Win7 X64. I suggest you remove every codec pack you've installed. and reinstall CoreAVC and MPC-HC. Though I suggest that you use MPC-HC's native DXVA filter. it looks better.

If something actually looks different to something else and you are not doing any post-processing, then something is not set up properly.
