Decoding of mp3 (and/or other media) with FP routines is extremely slow on systems w/o fp processor. No matter is it "soft-float" or "kernel-trap emulator". Both cases it is the emulator.(but SF is a litthe faster because it has no "trap" overhead). > Does anybody use MPlayer on MIPS? > What performance do you get? I used mplayed with libmad (libmad uses only integer ops to decode mp3). It consumes about 10-15% of cpu time (au1200) to play mp3 file. ()_() -( ^,^ )- -[21398845]- -- -<27.09.2005 11:33>- (") (")
