I've found that mplayer's measuring is not precise :( Here my test with using RDTSC: Old stuff: rd_tsc: 774377 rd_tsc: 765985 rd_tsc: 265309 New CPU optimized stuff: rd_tsc: 661154 rd_tsc: 641317 rd_tsc: 222448 New MMX2 optimized stuff: rd_tsc: 269544 rd_tsc: 329189 rd_tsc: 173110 git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@2824 b3059339-0415-0410-9bf9-f77b7e298cf2
