I don't know a lot about video codecs, but surely there are some functions that are generic to more than one codec. Implementing some of this generic functionality in hardware can allow anyone to write an accelerated decoder (encoder even?) for any format that can make use of the hardware functions whether it be MPEG or theora or whatever. Then since only generic functions and not decoders for any one format are implemented then perhaps that can keep opengraphics out of potential patent issues?
I'm just getting up to speed on it now, but other than the YUV<->RGB conversion Tim and I are looking at, my experience so far is that pretty much every (in use) video codec has the basic JPEG alphabet: Huffman, entropy, quantization, iDCT, et. al. I found at least some of this stuff on opencores... _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
