ramonchin Posted September 16, 2007 Share Posted September 16, 2007 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? Quote Link to comment
Kat-CeDe Posted September 16, 2007 Share Posted September 16, 2007 Hi, your GPU has not a very good h264 support build in so enabling dxva does not help very much. Ralf Quote Link to comment

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 Quote Link to comment

Ralf So nvidia lied me... 7950GT was said "It's perfect for 1080p H264" On the other hand, when is CoreAVC "hardware enabled" expected? Edited September 16, 2007 by ramonchin Quote Link to comment
CiNcH Posted September 16, 2007 Share Posted September 16, 2007 (edited) So nvidia lied me... 7950GT was said "It's perfect for 1080p H264" Come on... nVIDIA did not make a secret about what's being done within hardware and what is not. PureVideo HD H.264 Decode On the other hand, when is CoreAVC "hardware enabled" expected? 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. Edited September 16, 2007 by CiNcH Quote Link to comment

ramonchin Posted September 16, 2007 Author Share Posted September 16, 2007 (edited) 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? Edited September 16, 2007 by ramonchin Quote Link to comment
Tjod Posted September 16, 2007 Share Posted September 16, 2007 Has nothing to do with D3d Renderengine -> Moved. XP is better than Vista. If you like to get more problems go to Vista 64bits. Quote Link to comment
