- mp and mpeg_play are based on the stanford implementation. This is
- designed to run on *big* machines. Michael Van Elst replaced a lot
- of routines in mp with tight assembler ones, but he has admitted
- that he took the basic algorythms used as-is.
-
- The player algorythm is not optimised in anyway, for example should
- you get an I frame, then all sub components can only be the one
- type of block for an I frame, but the program checks every block each
- times and remakes the decision when it doesnt need to. I know of
- someone who looked into it and reckons that a decent frame rate is
- achievable even on an 030, he is pretty hot on this kind of thing,
- and I do believe him. What is needed is someone to look at the source,
- optimise it and create a new player.
-
- Hope this helps
