Purevideo H264 DXVA

Has anyone find a good working video codec using DXVA for h264 video? I've tried last Cyberlink, nero and elecard codecs (DXVA enabled)... and video is very slow, a lot of dropped frames. If I unchek DXVA, it plays almost fine but using a lot of CPU.

 

I have a nvidia 7950GT with last drivers.

 

Any solution?

Hi,

your GPU has not a very good h264 support build in so enabling dxva does not help very much.

All those codecs are not so that good in DVB application(Picture quality, stability). May be due to the various formats they have to deal with.

 

Although there is no DXVA support(expected soon) CoreAVC is by far better and CPU is pretty acceptable.

 

DVB community in majority come to that conclusion.

 

Cheers

So nvidia lied me... 7950GT was said "It's perfect for 1080p H264"

 

On the other hand, when is CoreAVC "hardware enabled" expected?

Come on... nVIDIA did not make a secret about what's being done within hardware and what is not.

Don't wait for that. CoreCodec people are still struggling with their DRM stuff...

 

CyberLink is the only decoder that seems to reliably support H.264 acceleration.

Cyberlink support very few h264 profiles... Doesn't it?

Are nvidia cards working in full screen (vmr) under vista?

 

I've got 7950GT and I'm thinking about migration to Vista... Under XP only Overlay is working fine... But you know, unnatural colours. :h

 

Is Vista 64bits better than 32bits one for a HTPC+DVBViewer system?

Has nothing to do with D3d Renderengine -> Moved.

 

XP is better than Vista. If you like to get more problems go to Vista 64bits.
