I have to admit that I am quite reluctant to do these things, first because mplayer already has a long list of dependencies and second, it takes me longer to test things under the various options and circumstances. If there is a *serious* reason to add something, of course I can do it. In the x264 case, the reason is a tremendous performance increase by using the ASM stuff. But for mplayer, only a very tiny fraction of the code actually uses ssse3. Turning off ssse3 and using the base system gcc does *not* completely turn off asm optimisation as it does for x264. It still uses mmx, 3dnow and sse123. I don't even have an ssse3 machine for testing. Do you have a video file for which decoding without ssse3 is too slow but fast enough with it? Riggs
