Arg.  It’s back.  I can’t figure out what combination of things makes it work or not work.

On an related note, they just released a new version of mpc hc.  A few issues:

1.  I was hoping they had DXVA VC-1 for Clarkdale, but unfortunately it isn’t there. 
2.  The really cool sync the refresh rate with the video frame rate feature doesn’t seem to work right with my setup. 
3.  mpc-hc.exe doesn’t terminate when using Haali or Intel Media SDK VC-1 decoder (hangs on desktop with MediaBrowser).  Only works with internal filters.  This was happening in the last version as well.

Hopefully, there will be a patch for these…

I may still use it though, other than these it is very impressive.

Sky Captain.mkv (VC-1, EAC3) 0-60 seconds

GraphEdit (no audio pin)
Haali -> -> Enhanced Video Renderer

I had to eyeball the numbers, but these are the results.

FFDShow                 Peak 11-20 – 14 median
Intel Media SDK
2.0.005 (dburckh)    Peak 29-52 – 33 median
2.0.006 (Intel)         Peak 29-52 – 34 median
1.5       (babgvant)   Peak 7-12  – 9  median

Clearly DXVA is not working in 2.0.00x.  Did you do some additional magic to force it in your 1.5 build?  I’m going to play with 1.5 again to see how it performs.

I don’t have any benchmarks against GraphStudio.  I’ll try that as well.

The MediaSDK VC-1 decoder is DXVA2 only on Intel GPUs (tested with an i5 and i3), on other GPUs it’s SW only (~15% on my Q6600 + ATI3650). 

Now that Sage has there own MKV splitter I’ve been using the ArcSoft TMT2 Video Decoder instead, so I haven’t messed w/ the Intel one for a while.

So, I should be getting hardware acceleration on my i3-540 in MPC HC with EVR, correct?  It doesn’t appear that is happening.  Is there something else I need to set?  I’m using the Haali’s MKV splitter.  I’m a little in the dark on what it takes to make DXVA2 work.  Does it require Media Foundation? 

I’m willing to read if you have a good post.  Most of the stuff I’m seen on DXVA2 is pretty muddy.  I’m pretty sure that DXVA2 requires EVR.  I’m not sure if it require Media Foundation.

Yes, I meant the 2.0.005 Beta version.  I was just abbreviating it.  So are they calling that Beta 1 and 2.0.006 Beta 2? 

Tell you what I’ll do to atone for my many sins on this post.  I’ll test 1.5, 2.0.0005 and 2.0.0006, ffdshow tryouts and post my results.  I’ll use a common file and time sequence.  I’ll use SpeedFan to track the mini-max CPU (Other suggestions welcome).  Might be a couple of days before I can get time to do all this…

The only thing is that is useful is how to disable the MS VC-1 DMO filter manually (there are tools for this).  Or what it takes to build the Intel WMV3 decoder to play VC-1.

I was getting major stuttering with the MS decoder and Intel 1.5, but  I’m having weird issues with AC3 passthrough.  Sometimes it’s fine, some times it stutters and dies.  I’ve even consider SP1 beta.  I have a work-around and I’ll give 1.5 another go. 

I’m a somewhat amazed that you are getting such low utilization with software rendering.  Do you have something bigger than a i3-5[3-4]0 or do you think you are getting HW acceleration? 

The only decent VC-1 decoder I have found is the MPCHC decoder (DXVA), which doesn’t seem to work on Clarkdale.  The MS one stutters even on my i7.  I was going to play with the ArcSoft one, but the ffdshow one is working pretty well.

On my i3-540 25-35%  (ffdshow tryouts 15-25%)

FYI:  H264 (DXVA is around 7%)
