| 819630 | 2009-10-12 02:20:00 | So the Media PC has an AGP nVidia 7300GT 512MB, running on a 2.4Ghz P4, Win7. What I *want* is to have it offload the decoding of HD Video (h.264) to the Graphics Card, because at the moment the CPU is doing all the work and it can't keep up with 1920x1080 video, only 1280x720-ish (CPU sits around 70%). So, I tried looking in to PureVideo and CoreAVC, still isn't happy :( Any ideas? Thoughts / suggestions / recommendations appreciated. Kind regards Chill. |

I hate seeing my GTX 260 sit idle while the CPU gets raped. :dogeye: Indeed! Is that card actually grunty enough to run 1080p? Pretty sure (for example) that VDPAU on XBMC linux only works with an 8800GT or newer? |

| 819633 | 2009-10-12 02:59:00 | Yeah well my 7300GT is outputting the desktop at 1080p. This says its supposed to work with PureVideo: www.nvidia.com |

| 819634 | 2009-10-12 03:01:00 | not quite what you asked about but this is a way to reduce the CPU usage when decoding h264-uses core avc eugenia.gnomefiles.org |

| 819635 | 2009-10-12 03:01:00 | I thought it was up to the individual program too do that. | plod (107) | ||
| 819636 | 2009-10-12 03:20:00 | As far as I'm aware, CoreAVC accelerates the decoding on the CPU. It can even be faster than some video cards. I don't think coreavc does anything for graphics cards. What program are you using to play it back? please don't say vlc, only newbies who don't know anything about codecs use vlc. I know video can be accelerated using media player classic. |

| 819637 | 2009-10-12 03:21:00 | I believe the 7xxx series can only accelerate MPEG-2 video (and MPEG-2 can be used for HD video...), not H.264. | Sherman (9181) | ||
| 819638 | 2009-10-12 04:06:00 | This page seems to indicate h.264: www.nvidia.com And I've been using MPC-HC, already tried with the coreAVC codec unfortunately :( |

| 819639 | 2009-10-12 06:00:00 | I use Arcsoft Totalmedia myself (came bundled with my Asus mycinema usb Dvb-t tuner) On my Media PC (P4 2.93GHz 1.5GB DDR 9400gt XP Home), CPU usage around 10% On my lappy (Core2Duo 1.73GHz 3GB DDR2 go7400 Win7 32bit), CPU usage around 70% Both at 1600X1200 on an old iiyama 510pro CRT. in both cases I have enabled hardware acceleration. I think the h264 decoder on the 7 series is the main limiting factor.:( |
