dxva is a codec feature, not so much a player feature. You should bug the ffdshow guys to work on a dxva implement of their generic routines, or the xvid guys (which would then allow ffdshow xvid routines to use it).
I remember back in the day when my ati aiw rage pro could playback dvd resolution mpeg2 files on a p100, simply because the rage pro did hardware motion compensation, while everyone else was complaining about how badly dvd's looked on their 300mhz systems. DXVA would be a huge step in the right direction, especially for a system that multitasks such as an htpc where it might be recording a tv stream while decoding a different one. I know most of the htpc users are using hardware mpeg2 cards, but if you haven't noticed even transferring to ide takes a good chunk of cpu. Even offloading just the post processing would result in huge speed ups.
But I digress, this is something you need to take up with the codec makers. |
