Hardware acceleration with CoreAVC

[jnmfox]

I was unable to get all of my h.264 files to play with the included decoders. I purchased CoreAVC (and installed ffdshow for HD audio) which allows me to play both my Handbrake transcoded files and mkvs without issue. I've enabled DVXA via the CoreAVC control panel but I am still getting CPU usage in the 40-50% and the CoreAVC tray icon shows I am not using hardware acceleration.

Is there something I am missing to enable hardware acceleration with CoreAVC in Sage?

Also, what codec does everyone use for VC-1?

Which version of CoreAVC are you using? Latest version uses CUDA hardware acceleration (assuming nvidia) which requires a DX10 compatible graphics card.

Latest version, 3.0.1 I think. I have an AMD 6670.

put it in graphedit and see if the coreavc codec is being used or if someother codec has higher priority.

AMD (ATI based) cards use a different acceleration method similar to CUDA called "Stream", but you need to check with CoreAVC website to see whether is supported. Last time I've used CoreAVC was with version 2.6.1 and CUDA was enabled, but my graphics card wasn't up to it. Also it might be possible that you need to purchase extra CoreAVC licenses, also I recall that some version didn't have multicore support or if you wanted the support you needed to upgrade to a more expensive version. I recall I stopped using CoreAVC when I purchased my first extender.

Are you trying to use it with Windows 8 as it looks like that isn't supported yet...

It supports ATI via DXVA. At one point the CoreAVC notification icon was turning red (ATI acceleration) but then stopped. My videos are playing without issue so I shouldn't complain but the HW acceleration would be nice. I'm using Win 7.

All this makes me appreciate my HD300 more. If I could only get one at a reasonable price.

TMT5 decoder is the best one for me. After that would be the MS decoder, you (IIRC) have to have either WMP or WMC enabled for DXVA to work properly.

How do you enable WMP or WMC?

Thanks for the tip I was having a problem using MS decoder on 1 client I started up WMC let it update closed it down and now the Client works great.

Just start then up and let them update.

I usually go into the "enable or disable windows features" section of the programs and features control panel applet and remove both WMC and WMP. After finding out that DXVA has issues if you do that, I put them back. Seems to work better now.

Thanks, I'll give that a try.

Do you leave the features installed or can you remove them after their initial installation?

WMC like to respond to the 'green button' unless of course your remove the feature

And of course you need the Windows Media Center Pack license on Windows 8 to enable WMC.

You have to leave them. You can disable the green button by renaming ehsched.exe and ehtray.exe. You'll have to change the owner of the file by going to security, advanced. But if you rename those files, the green button will be inactive unless you actually have WMC on the screen.

Along those lines can I simply stop the associated services and set to manual start?

Fine, do it the smart way...
