I doubt wrlib was made to process 512kbps stream in realtime ;-) However, FFmpeg built with CMOV optimisation shows ~1% performance improvement. First of all, assembly optimisations are very platform-dependant. Next, for every processor you have to implement several realisations, for ix86 they are MMX, SSE, 3DNow!, SSE4, SSE4.2 and so on. Hand-made MMX (as in our case) almost useless on current hardware and compilers... -- Regards, -- Sir Raorn. --- http://thousandsofhate.blogspot.com/
