I believe with a customized mpegdecoder and player, one highly optimized for the mini-mac hardware it should be entirely possible. Most of the performance issues with HDTV playback is the decoder and player are separated. ffmpeg --> mplayer.... etc..... The best boast to performance I've seen is having the AGP write code run concurrently inside the decoding loop... That is described on Intel machines in this paper: www.cs.princeton.edu/~chenhan/papers/icme2002t.pdf Code here: http://www.cs.princeton.edu/omnimedia/software.htm Which Ive referenced before on this list. The paper describes other optimizations such as macro-block arrangement for better cache locality.. etc... However, I believe using exisiting open source mpeg2 decoding code, and exisiting player code one could mash them together to "exploit the concurrency between the CPU and the AGP write buffer"(page 3) and come up with a HDTV capable player for the mini-mac ( and for much lower power machines )... .... Anyone going to 'donate' a mini-mac to me and let me try? ;) -- Anthony Vito [EMAIL PROTECTED] _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
