One issue is that even if your generic functions are sufficient to, say, do h264 idct and mc on the card, you then have to transfer the image back from the card to the CPU to do deblocking in software. Would only be a benefit if bandwidth was considerably faster and cheaper than CPU. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
