My trivial experiment shows 2 things: 1) It pays off bigtime to allow mjpegtools to use the MMX instruction set. 2) We only get a minimal benefit from compiling for athlon instead of i586. When the discussion of mjpegtools started, some people wanted local recompilations but these numbers to not support that idea. They do, however, strongly support the idea of building and distributing mjpegtools with and without the MMX instructions. [The former is in order to get the performance benefit, the latter in order to follow the Mandrake architecture policy] If you can help Austin in any way to set that up, we would all be very grateful. So far, Austin has only received vague instructions and ridicule despite his best attempts at asking polite and constructive questions. Narfi.
