DirectShow filters (DXVA) for G570

Hi all

I'm trying to set up a G570 for video playback, and have run into a persistent problem.

When using a various players and DS filters to use the 6370M for hardware acceleration of VC-1 video, I get the same error message:

"This application has requested the runtime to terminate in an unusual way. Please contact the applications support team for more information"

PotPlayer tries to play VC-1 video with its own codecs, but the result is unwatchable. I have CoreAVC installed, too, and it's happy to use DXVA for h264 video, but CoreAVC won't intrinsically do VC-1.

So far I've been using MPC-HC (32bit and 64bit) and Potplayer. I've tried the ffmpeg DXVA codec (32 and 64bit), and the Arcsoft VC-1 codec (32 bit). They all fail with exactly same error message. The system is using factory installed Windows 64bit HomePremium.

The laptop has video drivers versioned 8.790.9.0, and I notice the lastest version available is only a minor point release later, and both are dated last year. (The newer drivers weigh a cheerful 470M, too).

I'm a bit reluctant to try generic AMD drivers, I don't use laptops much (I'm doing this for a friend) and don't even know if generic drivers will work, let alone make any difference to the problem.

Has anyone else had this problem and found a fix for it?

Cheers

What does DXVA Checker report?

 

Hi namaiki

Here's a clip (attached) made with DXVAChecker 2.5 (later versions throw an exception at startup despite efforts to install runtimes etc).

I'm not sure how to interpret the results though. On another computer with an nVidia GTS250 there's an entry for

ModeVC1_IDCT: DXVA1/2, 720x480 / 1280x720 / 1920x1080

which is missing from the 6370's capabilities. Also, the DXVA-HD tab is completely blank on the 6370.

This isn't looking good; the CPU isn't quick enough to do VC-1 in software.

Have you tried LAV filters?

Does it provide any more details? Did you try using MPC-HC's internal VC-1 filters?

 

That was the complete error message.

Using the internal VC-1 filter gave me an error in atiumdva.dll and MPC crashed.

So now I have set LAVSplitterSource, CoreAVC, ArcsoftHD Audio and LAVVideo as the external filters, so no hw acceleration for VC1 files. It actually does wotk OK on the i3 except for one file, a short from Drillbit Taylor, and everything seems to have problems with it too. It doesn't even start playing on the current setup. This particular file has been the corner case that just won't work, and requires a lot of fiddling with. It's 00032.m2ts off the Drillbit Taylor BD for reference.
