[MPlayer-dev-eng] icc benchmark

[Carl Eugen Hoyos]

Hi!

Using Michaels suggestion -
http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2007-June/052274.html
- I managed to compile an optimized mplayer with icc. I immediately ran
a benchmark on my old h264 sample (fanta4 trailer). Both executables
where compiled with -fno-inline-functions for dsputil_mmx.o. (That saves
~2 secs.)

mplayer fanta4_720p.mov -nosound -benchmark

I will try to produce a patch, it would include something like the
following, would that be acceptable?
