Core i3 Intel HD Graphics - DXVA Issues
Hei,
Is anyone esle seeing artifacts/blockiness on H264 when using DXVA on Intel's Core i3 HD Graphics. I'm seeing it when using MPC-HC, ffdshow, etc. Guessing it's a driver issue. Thanks |

afaik intel has not provided casimir with this hardware yet so we cannot fix it right now.

there are 2 big problems to solve before we can release a new stable.

i worked around this by encoding with --no-deblock
cludgy i know, but not too bad considering i have a lot of very noisy HD stuff. it seems the DXVA gear isn't deblocking, hence the drifting out of whack, and random edges with trails of crap. encoding without deblocking eliminates this problem at the cost of coding efficiency.

Grab the latest drivers from Intel here...
http://downloadcenter.intel.com/Sear...ae+HD+Graphics I haven't tested recently however as far as i know there is no change in the situation. Also, wish Intel would introduce a gamma adjustment option! Both NVidia and ATI have it, so why not Intel!? Cheers |

Already tried that, won't let me install them as they are not certified (win 7 64bit). I'm searching if it is possible to force install them but might end up waiting for dell anyway. But VC1 dxva is also not possible at the moment as the intel driver doesn't provide the ModeVC1_VLD device.

Is there some temporary workaround to run deblocking on the cpu rather than through dxva on intel cards? Update: I found a workaround. Set the Microsoft DTV-DVD Video Decoder to Prefer in External Filters. It will use dxva and doesn't seem to have any rendering issues. Last edited by JohnPeterson; 8th October 2010 at 15:58. |

maybe it has something to do with the way the video was encoded?
I always assumed it's a problem with the video if it was giving problems with the microsoft filter. Last edited by mindbomb; 1st December 2010 at 17:44. |
