Help, Hardware Acceleration

[ocnos]

Hi,

Could anyone help me with this? I bought a mb with ATI HD3200 just for playing HD movies and now I can't get it working. I use Vista and MP. I have tried everything: ffdshow, Cyberlink codec, MP Enhanced Video Renderer option... But my CPU keeps at 60-70% usage, sometimes more, when playing HD

Click here for link to avivo codec

And for tweaking your HD3200 settings see here ATI HD Registry Tweaks

Which version of cyberlink codec did you use ?
You need at least Powerdvd 7.3 Ultra to get hardware acceleration.

I think you have to activate Aero in Vista to get DvXA when using ATI and Mediaportal

Thanks.
I have updated my avivo driver. My PowerDVD Version is 8 Ultra (plays blurays). I have Aero enabled.

However, I can't get HW acceleration enabled. For a start, how would I know if it was enabled? My CPU usage playing beowulf 1080p is around 50%, and I have a nice AMD dual core processor.

What exactly do these ATI tweaks? I didn't dare to try them... Would they help?

AFAIK these tweaks are not necessary for your setup.

Did you try to play the movie outside MP with Powerdvd?
Did you check the option "Enable hardware acceleration" in PowerDVD config?

I have set hardware acceleration in PowerDVD. It plays a bluray with less than 10% CPU usage.

However, I can't get PowerDVD playing any mkv file. I have read in forums that maybe it's impossible for it to deal with that container.

I have tried HD wmv and avis, but in those cases the "enable hardware acceleration" option was permanently disabled

In other players (zoomplayer, mpc, mpc hc with EVR) I can't get the CPU usage under 50% when playing MKV.

I don't really understand how this works... I see now that it isn't strictly a MP problem, but any help will be welcome!

Some mkv files are not coded correcty to play in hardware.

Go here: x264 Encoding Options for Hardware Compatibility & DXVA - Page 4 - AVS Forum and download the idc changer. You have to load the mkv file with this tool and set the level to 4.1 (5.1 won't be hardware accelerated).

Another thing to look at is that you don't have to have any postprocessing enabled (no ffdshow or directvobsub).

Also user EVR as rederer i Mediaportal. Do you have other codecs like CoreAVC and FFDShow Tryouts you have to make sure that they aren't used even if you have choosen Cyberlink as you codec in Mediaportal.

To play .mkv in PowerDVD you rename the suffix to .avi or .mp4. I've a CPU load of 2-4% when playing h.264 encoded .mkv with DxVA and 40-50% without.

My problem was, indeed, with the subtitles postprocessing. With VSFilter disabled, I have achieved Hardware Acceleration.

btw it works no matter if Aero is on or off.

I now face 2 problems:

1. Without VSFilter I can't manage my subtitles, and MP complains about it. is there an alternative that doesn't "bother" the hardware acceleration feature?

2. This is the worst part: there are some files that won't play, or will play with distorted image, due to (I suppose) the "purity" of the h264 encoding. With this files I would have to disable HA, something that won't be possible with my remote within MP.
I suppose that de IDC Changer tool could fix those files (all of them? maybe only some of them?) but it crashes both in XP and Vista.
