Without having looked at it in detail, some thoughts. We need to do two things: motion compensation, and iDCT.
http://www.xfree86.org/~mvojkovi/XvMC_API.txt it
I reckon there are some people at the Theora lists that know much more about this stuff than we do. Perhaps we should ask them what they would like to have?
Also maybe not for this version of the card but later might look into http://dirac.sourceforge.net/index.html It uses wavelets and not Inverse Discreet Cosine transforms AFAIK. They also use "overlapped block motion compensation". http://dirac.sourceforge.net/documentation/algorithm/upconversion/index.htm Up-conversion and down-conversion of pictures - Fast up-conversion and down-conversion used in motion estimation and compensation http://dirac.sourceforge.net/documentation/algorithm/global_motion/index.htm Global motion estimation - Approximation of global motion between frames -- http://dmoz.org/profiles/pollei.html http://sourceforge.net/users/stephen_pollei/ http://www.orkut.com/Profile.aspx?uid=2455954990164098214 http://stephen_pollei.home.comcast.net/ _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
